The Aspire Nautilus 2 e cig tank has to have been one of the most hyped releases by a vape company ever – well almost.

nautilus 2 colours

They really milked this release didn’t they lol!


All the razzmatazz surrounding the Nautilus 2 couldn’t have passed you by unnoticed lol and like me you probably got out the original and had a play on it to see what all the fuss was about.

So Does the Nautilus 2 Live Up to the Hype?

Anyway…I’m sure that pretty much every single e-cigarette user out there has at some point used the original Nautilus tank on their vaping journey – I certainly did.

I’m a DTL vaper nowadays but I still enjoy MTL vaping especially first thing in the morning – old habits – using the K2 tank – also from Aspire.

I’ve been using the Nautilus 2 for some time now – so has it become my go to MTL tank?

Will it take a place on our Best MTL Vape Tank list?

Let’s see if all that hype was worth it – unlike the luke warm reception the Nautilus X received after a similar social media teasing campaign 😉

In the Box

It’s a dinky little box with the front window revealing a tantalizing glimpse of the Nautilus 2 tank.

nautilus 2 box

And yeah half of the front and indeed back is taken up by the now obligatory TPD nicotine warning – *sighs*- still I guess it saves on design costs lol.

Inside you’ll find:

  • 1x Nautilus 2 tank(Pre-installed a 0.7ohm coil)
  • 1x Extra Coil(1.8ohm)
  • 1x Extra Glass Tube
  • 8x O rings
  • 1x User Manual
  • 1x Warning Card
  • 1x Extra Drip tip

Nautilus 2 Specs

  • Height: 53mm
  • Diameter: 22mm
  • Capacity: 2ml
  • Material: Stainless steel / aluminium

The fact it comes with x2 coils is a nice touch.

However despite one of them ‘appearing’ to be sub ohm [0.7ohm] Aspire gives its top wattage at 23watts.

You can of course take DTL hits and to be honest I quite enjoyed that way of vaping on this nifty little tank but more on that later.

Key Features

Apart from the design – which we’ll get to – and the fact it comes in an array of colour choices – it’s the airflow that catches the eye.

The original had x3 settings and to be fair even wide open the draw was tight.

nautilus 2 airflow

The Aspire Nautilus 2 has x5 airflow holes each one diminishing in size. The beauty of this is you can tailor your perfect settings.

Wide open and the draw is airy but with just enough restriction and of course the less holes you open the tighter it becomes.

You get a fabulous vape whichever way you set it and with just the tiniest hole open – the vape whilst restrictive and on the warm side it isn’t in any way uncomfortable and the flavour really does zing!

How To Fill The Aspire Nautilus 2 Tank

It’s a top fill design which simply means you do the following:

  • Unscrew the bell shaped outer sheath
  • Fill straight into the tank [avoiding the central chimney] – there’s plenty of room too.
  • Ensure the coil hasn’t come loose
  • Replace the outer sheath
  • Waith for 5 minutes for the e liquid to soak into our coil
  • Vape on!

How To Fill The Aspire Nautilus 2 TankUnfortunately it’s not what you might call a ‘clean hand’ coil swap and you will lose any e-liquid left inside the tank when it comes to swapping them out.

Depending on the coil you’ll be vaping between 10 and 23 watts.

Design and Build Quality

I’ll be honest when I first caught a glimpse of the Nautilus 2 my first reaction as one of horror [sez me with the original caged in that weird cut-out sheath].

nautilus 1 and 2 compared
my trusty old Nautilus

Given its bell shape I did call it the ‘bell-end tank’ [lol] however it kind of grew on me and now I’ve had it in my hands so to speak I actually really do like it.

I now can’t get away from thinking it looks more like a buoy – you know those things in the sea that ships and boats bump into – so the name Nautilus kinda fits the look if you catch my drift.

nautilus 2

So I now call it the ‘Hello Sailor’ tank – ooo get me 😉

Anyway design wise I think it’s stunning – but like most things it’s subjective. I can only say initially I hated it but in my hand and on a mod I love it.

nautilus 2 hand size

I received the black version and Aspire like to point out the tank [apart from the stainless steel version] has an anodized finish which gives it a very nice matte look and feel.

Build wise and as you might expect from Aspire everything is machined to perfection.

There’s no screeching or ‘crunchy sandy’ sounds off the connections which screw together snug and sweet.

You get x2 vase shaped mouthpieces – one that matches the colour of your mod and a stainless steel one.

drip tip nautilus 2

I have tried other tips and with a bit of O ring fiddling about I did get a couple on.

All in all it’s a solid well-made beautifully designed piece of kit and in the time I’ve been using it there’s been absolutely no leaking whatsoever.

How Does Aspire Nautilus 2 Tank Perform?

First and foremost this a MTL [mouth to lung] tank – perfect for beginners as it mimics smoking a cancer stick – I’ll get onto the DTL element in a minute.

I tried a variety of e-liquids including 50-50 and 70-30 percent VG and PG mixes.

nautilus 2 parts

The Aspire Nautilus 2 was able to handle the thicker e-liquids and wicked like a dream.

Even with the airflow wide open the taste was simply sensational and if you like a rich flavour and a warm vape – close those holes off a bit and you get a sumptuous vape.

On the 0.7ohm coil I hit my sweet spot at 21.5watts vaping Black Note E Juice, a 50/50 tobacco e-liquid. I adore this flavour and the Nautilus 2 took it to a new level for me.

Obviously the throat hit will depend on the e-liquid – nicotine level etc.

But what I can say using a 18mg nic liquid [old school haha] the hit and flavour was fantastic – as close to a stinkie as you’ll get.

With a 70/30 3mg e-liquid (JAC Vapour Premium E Juice) again the flavour was intense and of course the vapour was much thicker.

The throat hit was of course much smoother and I instinctively began DTL vaping and to be fair it was quite a nice lung hit.

nautilus 2 on the pebble

I would say it’s a great tank to ‘have a go’ at DTL vaping – just make sure you turn down that nicotine level 😉

On the 1.8ohm coil things it’s fair to say calmed down a little – only a little mind.

The flavour dimmed a touch due to the lower wattage I guess so for me the 0.7ohm just shades the two in overall performance.

Again that’s subjective.

As a regular vaper of both styles I’m seriously impressed with this tank – seriously impressed.

“Well hello sailor” indeed 😉

What I Like

Never thought I’d say this but I love the design – how fickle am I lol.

The ease of filling is a bonus as is the fact that all the other Aspire Nautilus coils will fit this new tank – I found two left in an old packet which put a smile on my face lol.

The airflow control is exceptional and I mean exceptional.

Most of all I love the taste.nautilus 2 wismec mini

I did a flavour test using fresh coils on the original Nautilus and the newer version and the difference whilst not palpable was noticeable – and that’s despite using the same coil – e-liquid and wattage.

What you put that down to is up to you – could it be the pronounced domed bell shape – the superior airflow?

Who knows – but there was definitely a better cleaner and I have to say smoother overall experience on the Nautilus 2.

What I Don’t Like

Struggling here.


Still struggling…

OK to be honest and after sleeping on it [not literally lol] there’s not a lot if anything I don’t like.

I know some folks outside the EU will moan about the 2ml capacity however that is a ‘design’ feature forced upon Aspire by the EU’s TPD legislation.

As a regular MTL vaper I know that 2ml lasts a good while – unlike a 5ml tank of 3mg e-liquid when we’re sub ohm vaping – so whilst it may be a negative in some minds – to me it ain’t 😉

Final Review Verdict

As I said there was a bit of this old school vaper that wanted to dislike the Aspire Nautilus 2 – no idea why call me a grumpy old sod who rejects change and new-fangled stuff.

nautilus 2 on defender

However as David Brent once said ‘you’ve charmed me’ and it really has.

From its stunning design [buoy not bell-end] – its ease of fill – ease of use and most importantly its flavour – this is a super little tank perfect for beginners and regular MTL vapers alike.


If I was sat adrift on a buoy and I dropped the Aspire Nautilus 2 into the ocean…

Would I dive in and get it?

Damn right!


  • Awesome air flow
  • Lovely design
  • Compact
  • Superb flavour
  • Cross series coils
  • 0.7ohm coil adds a new dimension
  • New design sheath way better than the cut out I have lol
  • Decent price


  • 2ml capacity might annoy some [blame the EU]

aspire-nautilus-2-reviewWell worth the wait and indeed the hype - the Aspire Nautilus 2 is a must have tank.


  1. Well, gave it a few weeks, and it’s now officially binned. The tank looks fantastic, but the airflow is way too tight for MTL use. You really have to suck on this, and that can easily lead to throat muscle strain. That’s opening all holes fully. As a check, I dug out a Kanger Aerotank and it was such a relief that I kept a four year old tank as a spare. Much looser draw, lots of vapor production, perfect little pen style MTL tank. Such a reminder that the rise of sub-ohm has totally left MTL folk in the wind. I’m sure the Nautilus with a sub-ohm works perfectly with your diaphragm doing the heavy lifting though!

    You know, I think I’ll actually go buy another Aerotank. Before MTL tanks completely exit the stage…

  2. For everybody struggling to fill the nautilus 2 tank. I recently purchased this with the zelos and read a review online of how to use best before using it myself. On one of them it stated that when filling the tank, just before the last tighten of the “bell end” outer sheath to tip it upside down and tighten as the air that remains in the tank when compressed down by the outer sheath forces the liquid through the coil.

    It worked for me. Just thought it could help.

  3. I had to laugh at your “would I dive in after it” comment. I had to buy this kit today after literally dropping my old eleaf in the sea! No I did not dive in after it šŸ˜‚

  4. I have been using this tank now for about three months – a miserable three months. I fill the tank every day, just about once per week I can NOT get the tank open. it’s awful. if I don’t tighten the outer layer, it leaks – if I tighten it too much, I can’t get it off! I have to use a rubber/gripper that is a kitchen tool you use to open jars! this is not a true ‘top-fill’ – how do I find a true top fill that I won’t have to fight with to fill???

    • Try tossing the tank in the freezer for a couple minutes. Sounds strange… but it’s helped me many, many times with stuck tanks.

  5. Hiya im using the zelos kit with the nautilus 2. Im finding that i have tons of vapour but no flavour. Yet if i vape on my aspire k2 i get tons of flavour. I bought the zelos kits because the flavour was said excellent but i cant taste it. Im using 70vg liquid which tastes amazing in my k2

  6. So, I’ve had this tank with the Zelos kit for a while now, and im struggling to find liquids that keep their flavour for chain vaping, ive tried numerous different liquids now, ranging from 80vg/20pg to 60pg/40vg and cannot find more than one or two that im really happy with, can you please recommend me some A – fruit based liquids that work well and B – some menthol/fruit liquids?? Thanks in advance šŸ˜€

    • Hey Mark,

      I can tell you what I like but that is of course no guarantee you’ll like them too šŸ™‚

      Nasty Juice – Not nasty at all! These are fruit based and have a cooling effect that’s really refreshing. Not a menthol cooling though it’s more subtle and for my tastes far better. Really interesting and recommended. You should be OK with the 70VG in the Nautilus, although I was using these in sub ohm tanks with bigger coils.

      Vaporfi Grand Reserve is another quality range of juices. Click the link previously to check out the review <---. Colonel Boom’s Ceasefire was a favourite fruit mix but I vaped too much and got the dreaded vapers tongue.

      The other fruits I like are from Twelve Monkeys and Illusions Vapor. But both are high VG (80+) though and aren’t necessarily the best choice for the Nautilus coils.

      Let us know how you get on!

  7. Hi, All i seem to be getting lately is a burnt taste, i have literally just gone and bought this tank, filled it with 12mg left for a good 20 mins and again burnt taste, what am i doing wrong? its on 12 watts…….i am at a loss at the moment! rang the shop back up and they have said it could be that the 12mg is too high! can you please offer me any advise as i’m really getting fed up! Thanks šŸ™‚

    • Hey Joanne,

      If the coil has a burnt taste then you may need to replace the coil. Depending on how bad it is the coil may be a goner unfortunately.

      But first, try taking the wattage down a touch, see how it is and work your way back up a little again to 12W. Or if the vape is OK at 11W then stick there.

      Also, may sound strange but vaping is different to smoking in the way you do it.

      Just gently inhale, slow and smooth rather than sharp draws. You don’t really need to do the latter when vaping, the tank/coil does a lot of the work for you.

      Basically, you need to give the juice time to pull through the small holes on the side of the coil, through the cotton and onto the coils. Another word you may see describing this is ‘wicking’.

      Also, what PG/VG ratio e-juice are you using? ie: 50PG/50VG, 40PG/60VG etc. A juice higher in VG is thicker than one higher in PG.

      So if you are using the 1.8Ohm coil then it’s recommended to stick around the 50/50 ratio.

      Let me know what you are using Joanne.



      • Morning,

        I’m using a mixology one with a 50/50 I went back to the shop yesterday and they sorted the flavour…..luckily you get 2 coils, i wish i could say all is now good……but……. every time i add liquid its flooding, i tighten everything before adding the liquid but its still flooding, i must lose 1/3 of the liquid each time, am i doing something wrong?

        Thank you

        • Just getting around to comments now Joanne šŸ™‚

          When you say flooding to you mean e-liquid is getting into the base and coming out of the airflow holes?

          – Might sound a silly question but where are you adding the e-liquid?
          – How much do you fill the tank?
          – Are you making sure no eliquid goes down the center of the coil?

          Overfilling and juice getting down the center of the coil can cause flooding.

          It’s always a good idea to take the tank apart, clean everything under warm water (not the coil) and dry fully.

          While the tank is apart just check the seals look to be in place.

          Make sure the threading on the coil head is dry

          – Put you coil back in place firmly. It should go in smoothly, ensure there is no cross threading or parts of the thread that is damaged.
          – Put glass back in place
          – Close the airflow holes
          – Fill just half way up the coil
          – Replace outer cover – Don’t screw too tight! Just enough
          – Leave to sit for 10-15 mins with airflow holes closed.
          – Set wattage low and work your way up.

          Let me know on the above Joanne.

          • Sorry my original reply disappeared but reappeared after the second reply so wasnt sure if you had received the first one.

            I am adding the liquid to the tank between the glass and the coil so i know its in the correct place šŸ™‚ as i’m filling i can physically see the liquid leaving the tank and flooding the coil, everything is correctly installed (well i’m guessing it was as the lady at the shop did it all for me so i’m just taking off the top and refilling, but making sure everything is tight but not too tight that i can loosen it again) i add liquid to about halfway up the coil so its defo not overfilling, however i have realised that i dont close the air flow holes, so next time i will try closing them.

          • The only other thing I can think of Joanne is a faulty coil could be the issue. Have you tried a new coil?

            And.. Just to be doubly sure šŸ™‚

            When you remove the outer case to refill, you re-tighten the coil before refilling?

            The only other thing if it’s coming out that fast is the connection between the coil and the base. Just be sure all threading is dry and clean, the thread on the base where the coil screws in and the coil head thread itself.

          • I have the same problem … bought it today.. took it out from the box filled it up and now after couple of hours I looked all liquid is gone… at first I thought alright maybe just at beginning… I filled it up again and realise that all liquid is coming out from the air flow holes… I read the comment about take it a part and try to clean it but I can’t get that glass tube off…
            thanks šŸ™‚

          • Hi Mundra,

            Take a look at the response above. Sounds like the coil isn’t seated properly.

            If you can slide your finger nail in at the base of the glass it should come off easily as it’s just held in place by the O ring. Try running warm water over that part of the tank as well, should help ease it off. Just to sat the coil shouldn’t be getting a soaking so please remove before introducing any kind of water šŸ™‚

  8. Hey guy I am relativly new new to vaping (3months) started with a eleaf istick 20w which is great no issues loved it still do. How ever the time came for an upgrade and I thought I would get the aspire zelos 50w with the nautilus 2 tank (came as a kit with 1.8 and 0.7 coils). I used 30pg/70vg juice from rejuiced (which is nice tasty too) am looking to see what the best coil and wattage setup would be for this pg/vg set any help and advice would be great and thanks in advance

    Paul šŸ™‚

    • Hey Paul!

      The 70VG juice will be better with the 0.7ohm coil. As for wattage, this is very much a personal preference and dependant on your flavour. I would just start at around 15W and work your way up until you find the right setting for you.

      I personally like the 0.7Ohm around 19W with a 70VG juice.

      With the 1.8Ohm coil I tend to try and use 50/50 or max 60VG/40PG juice. Again, sam goes for the wattage. Start low and work your way up until you hit your sweet spot.

      Let us know how you get on mate.



      • Hey Jonny

        I sound advice will give it a go. Been finishing my old juice so I will change the coils after cleaning the tanks. I know in previous comments here u use this device in terms of the tank do u know if it can be extended Ave seen the glass to extend others (again nood question lol) I will defo give this a try and let you know how I get on. Found this review very helpful too.

        Cheers again Jonny


        • Thanks Paul,

          No, unfortunately there isn’t an extension for the Nautilus 2, or not one that I have seen anyway! There were extensions for others but I think with the outer metal cover on the nautilus 2 it makes it a little more difficult.

          Keep us updated mate and be sure when refilling you make sure the coil is screwed in place properly, can sometimes come unscrewed a little when taking outer cover off. What I find works is not screwing the outer cover on too firmly!



      • Hey Jonny,

        Just an update as asked and thanks again for the advice been awesome.

        So took your advice using to 0.7 coil also worked through the wattage mine seems to be best at 19.5 /22.5 with the 30pg/70vg mix from rejuiced as before and it’s going like a dream a few times I’ve got a burnt taste(only with certain flavours.This was fixed just by dropped the wattage and it’s fine. also using a vapouriz voltair tank too which I need to reduce the Watts from time to time as a taste of burnt I think it depends on the flavour as to what the best Watts are (you will know better than me as am still classed as a nood lol) with the aspire zelos with nautilus2 tank I cant seem to find the temp controls and other settings not sure if I need this or not. But no leaks or coil coming out all been good.

        Thanks for the advice and stuff has worked a treat ā˜†ā˜†ā˜†ā˜†ā˜†


        • Good to hear Paul!

          Yeah.. I get the onset of dry hits now and then when using a 70VG juice in the Nautilus 2.

          Basically, the higher VG is a little thicker and the Nautilus coils are quite small, as are the holes that allow the juice to soak through to the cotton. The result is that as you take say 3/4/5 drags in quick succession your cotton starts to dry out as the juice takes time to re-soak the cotton. This is also known as wicking which you may have heard.

          I can kind of tell when this is going to happen so just hold back a short while or reduce the wattage as you’ve already sussed.

          You can also try a couple of drags WITHOUT pressing the fire button. This can help draw the juice through to the coil a little.

          Flavours can also have an effect if you are using sweeter flavours.

          Temp Control – You’re right, you don’t need this with the coils you are using, stick to the wattage. Temp control only works with different coil materials which the Nautilus coils don’t have.

        • Jonny

          I ment to ask if I was wanting to get a sub ohm tank could I use it on my aspire zelos? And what would be the best on In your opinion to use for the kit?


  9. Mate, just bought one of these bad boys and struggling madly.

    Every time I try to top it up the coil comes away with the dome.

    Short of getting the pliers out to screw in the coil I am at a loss. Any suggestions?

    • Hey Dudds,

      I had this a few times when I first started using. This is what I did to fix.

      When tank is empty

      – Unscrew outer sheaf
      – Remove glass (you may need to just slide a nail around the base of the glass to pop it up
      – Screw the coil in firmly by hand
      – Glass back on
      – Fill with juice
      – Important bit: Screw outer sheaf back on – Do this so it’s on (obviously) but don’t over-tighten, it doesn’t need to be screwed on super tight.

      Because the coil acts as the chimney it connects to both the base and the top cap/outer sheaf.

      I always manage to refill when the tank is pretty much empty, but if you have a bit of juice left in the tank then you could use a pair of slim pliers to tighten.

      After I did the above though I didn’t have the coil screwing off problem.

      Let me know how you get on mate.


      • Flavour great, air flow great, design dreadful, glass unscrews, coil unscrews at best tank gurgles when refilled. I have spilt more juice than care to mention and I suspect the poor design will goose the battery. Now using my trusted aspire K3 tank with zelos, no problems-no leaking. Compromise on flavour a bit, but worth it. the Nautalis 2 is useless. Do not buy

    • If by DL you mean direct to lung I’d stick with zero or 3mg šŸ™‚
      I use quite high nic for mouth to lung between 12 and mostly 18mg – what can I say I’m old school and miss the hit šŸ™‚

  10. Just binned my one after 2 weeks of non stop leaking & gurgling. Absolutely rubbish. Many people have said the same. The design is flawed. Total waste of money and i paid Ā£25 for the pleasure. Never again will i believe the hype of an aspire product online or the shop seller who mugged me off with his shit waffle!!!

    • I totally agree and can only think that the reviewer doesn’t vape with this kit 24/7. Leaks like crazy, messy design which means the atomiser unscrews from the battery virtually every time you try to remove the “bell end” cover from the leaky glass tube!

      Too many fragile parts too mean “Aspire” milk the hell out of you – when inevitably due to the rubbish design the glass breaks or the coil sticks to the bell end case and unscrews like mine has a few times and your faced with having to order replacement parts.

      I’ve been vaping for 4 years and tried loads of kit and this earns a fair 1 out of 5 stars – for serious heavy duty use -avoid!!!

      • I can’t speak for Neil on the amount he uses the Nautilus 2 but I use it on a regular basis as my go to MTL tank (although not 24/7) and I agree that the coil coming loose when unscrewing the top cap was a major pain in the ass at first.

        It didn’t cause me leaking personally though as I was only unscrewing when the tank was due a refill and I always made sure the coil was screwed down securely again before refilling.

        I did find after screwing the coil down tight and going easy on screwing the top cap on afterwards that this helped stop the coil unscrewing as one with the top cap/outer bell case.

        Never had any glass break in any tank though, bar once when I dropped a Kanger sub tank on tiled flooring.

        Although, I agree Jon, they need to address the coil unscrewing in some way for future updates!

        • As it says in my profile I use the nautilus 2 daily so yeah 24/7 šŸ™‚ the only leaks and gurgling I’ve had is if I’ve overfilled and as Jonny mentioned screwing everything back together a little too tightly can mean you have to remove the whole thing to get it apart for filling.
          To be honest whilst it can be annoying I don’t see it as much of an issue – but let’s hope the Nautilus 3 if there is to be one will have a simpler top fill and maybe even a clean hands coil swap šŸ™‚

  11. Hi Neil, just getting to grips with progressing from starter pens & your reviews have been really helpful – thanks. I’d love to know what the favourite tobacco liquid you mentioned is?

  12. Your review was one of the reasons why I bought this tank. And as you said, for an ex-smoker it’s vaping experience is probably among the best out there.

    But what drives me nuts is the refill. I honestly don’t know what I am doing wrong but on every single time I refill the tank I end up with a serious amount of liquid inside the coil chimney. Sometimes it’s enough to turn it on it’s head and fire a few times, sometimes I have to shake it out and a visible drop comes out of the driptip or I have to use some papertowel rolled tight to soak out the liquid from inside the coil. Without doing this I get nasty hot spits. Once it’s cleaned I can vape without any spits until I refill again.

    This happens with the 0.7, the 1.6 and the 1.8ohm coil on both of my Nautilus 2 tanks. I am careful to not fill any liquid into the coil and I also never fill over the max-line. What could I possibly do wrong? It appears as if the liquid gets soaked into the inside of the coil chimney from below. The coil is screwed in tight and it does not make a difference if I use some pliers to screw it a bit tighter or just my hand. I usually use a 75VG/25PG/10Nic mix but it also happens on 50/50 mix. It’s even worse when I use a CBD mix with 70VG/30PG (that’s what the 2nd Tank is for). And as I said, once I’ve cleaned the chimney I don’t have the problem anymore until the next refill.

    I would very much appreciate if you (or someone) could point me into the right direction because out of desperation I’ve ordered a T22 now just to have some piece of mind.

    • Hey Raphael,

      A tough one this as it looks as if you’ve tried all the solutions that would normally fix the issue, which sounds like the coil is flooding. The PG/VG mixes that you have used sound like they should be OK as well, not too thin as to flow through the coil.

      I personally use this tank for my MTL vaping on a regular basis and haven’t had this problem. Although every time I refill any tank I have a routine of giving all parts a wipe down before refilling/changing a coil.

      So just kind of thinking out loud here…

      Could you be getting a condensation build up in the mouth piece that is adding to the excess moisture build up?

      Could it be when replacing the top/outer tank after filling, does this look to be screwing on to the top of the coil securely?

      Sounds simple but it may be worth taking the tank apart fully, giving it a clean, drying with a paper towel and reassembling. And when refilling ensure the threads on the outer tank that attach to the top of the coil are clean and dry.

      I would have said it’s possible you have a faulty coil but it’s very unlikely all three with different resistances would be faulty.

      You mention you have done the tissue rolling and mopping trick and it has worked, this is also what sorts out gurgling, popping and excess juice on the coil for me as well.

      I’ll have a play around with my Nautilus 2 and see if I can see another solution but if anyone else has had a problem with their Nautilus 2 tank leaking though the mouthpiece then feel free to share your fixes in the meantime!

  13. Like someone else, after about a week, I have been plagued with leaks as well.

    As a newbie I was told that with the Zelos /N2 combo (kit) I should only be vaping on max 15 Watt with the 0.7 ohm coils and that a ‘higher’ VG content (40 if you can believe that was called ‘high’) is what is causing the leaks because the holes on the 0.7 coil are too tiny.

    I was told to try reducing the Watts to 14 and add some PG to my mix.

    I think this advice is bonkers and, as a newbie, I really do need to resolve this issue if I am going to stay off the cigarettes as I can’t afford to buy another tank or mod yet.

    So I have tried 70/30 PG/ VG and 60/40 (adding 1.3 nicotine 100 mg in a VG base to 10 mls of PG/VG). We cannot buy nicotine ready-to-vape in Australia and must get our nicotine from overseas (mine is top grade from the U.S.) and mix it in ourselves (also bonkers).

    Your help really appreciated !

    • Hey Leigh,

      I feel for you in OZ, absolutely crazy laws over there regarding nicotine in juices!

      Good to see you are questioning that advise, does seem a little odd. The wattage may kind of make sense with the 1.8Ohm coil but not the 0.7.

      I use the Aspire Zelos/Nautilus2 kit on a regular basis when I want that mouth to lung vape.

      It’s rated for use at 17-23W, and while these ‘recommended ratings’ on all coils are just a guide, I find they are pretty accurate on the Nautilus 2.

      I personally use my Nautilus 2 with 0.7 ohm coil around 18W and upto 20W depending on which juices I’m using. I find different flavours are better for me at different wattages creating warmer/cooler vapes.

      As you can see in the review, Neil found 21.5W was his sweet spot.

      So.. A little strange that someone would recommend a max 15W with the 0.7Ohm coil.

      In short, there is no ideal wattage for all. It’s personal preference and just takes a little experimenting, start low and work your way up until you find ‘your’ sweet spot.

      Not sure what they meant with ’40’ being high either?! Maybe they were referring to a 60VG/40PG ratio?

      If so then it should have no issues with that. Neil and myself have both used 70VG/30PG with no issues.

      It’s not that common to see juices with a PG higher than 50/50 nowadays.

      OK.. So leaking.

      It could be that you are using too high a PG juice in both instances. You can check out our PG Vs VG article here for more info on both. but… 70PG/30VG is likely to be a very thin juice. PG is thinner than VG.

      Thinner juices could wick too quickly resulting in the juice just flowing through the cotton down via the center of the coil into the base, exiting via the airflow holes.

      Another reason for leaking from the airflow holes is that the coil isn’t screwed in fully.

      I have found, on occasion, that when unscrewing the outer cover to refill the coil can unscrew a touch as well.

      So, before you refill, make sure the coil is screwed in properly before putting the outer piece back on.

      It’s also worth, after filling, just to wipe the outer glass and the inside of the cover with a tissue to mop up any juice residue. I have found when I didn’t do this that you get a little juice showing on the outside of the tank.

      Not sure where you are from in OZ but heat can have an effect. If you are in a cool or AC room and then venture outside into higher temperatures then the juice thins out and can cause leaking. This happened a lot to me on a trip to South East Asia a while back.

      In short, I’m thinking it could be a result of the super high PG juice you are using. If you try for a 60 VG juice I think that may help a little.

      Let me know how you get on though and if you have any other questions please ask away.



  14. **Noob question alert!**

    Will this tank work with an aspire K3 battery? I need an alternative as the ‘glass’ part of the K3 tank is not very well protected and I’ve cracked 2 in the past. Thanks for any replies.

    • Hey Dan,

      Clumsy vaper hey! We’ve all been there šŸ™‚

      The Aspire BVC coils that normally come with the K3 are (99% sure) compatible with the Nautilus 2 tank so yes you should be just fine to use the Nautilus 2 tank with the K3 Battery.

      These are the coils I’m talking about –


      The Nautilus 2 tank is 22mm in width. The K3 battery is just 18mm in diameter. So it might look a little odd. Personal preference there though!

      Also, you won’t be able to use the 0.7Ohm coil with the K3 battery as the power just won’t be there.

      Not sure what coils you use at the moment but 1.8ohm should be just fine.



    • Hey Paul,

      I’ve not personally experienced any leaking with mine.

      Are you using the same e-juice for both tanks? If so what is the PG/VG ratio?

      A couple of things to try though.

      When unscrewing the outer case to fill be careful the coil itself doesn’t come unseated even half a turn.

      With mine I HAVE noticed that sometimes the coil can screw out with the part of the tank that you unscrew to fill.

      Before filling just make sure your coils are screwed into the base fully, don’t over-tighten just finger tight.

      Another thing to try: Take the tank apart fully, clean (including the threads on the coil and the threading where the coil screws in) and re-assemble.

      May also be worth having a look over this e cig tank troubleshooting guide that may help.

      Let us know how you get on.



  15. That Aspire Nautilus 2 Tank, looks nothing like the one I’ve just purchased. It has a 5ml tank and fills from the bottom. Someone explain!!?

  16. Bought the Zelos a little over two weeks ago and well what can I say, so far so good, I’m pretty much impressed. Jonny your review of the Aspire Zelos is fabulous, even the mention of the bell shape is a must lol, only thing I don’t like about it, is that 2ml tank, everything else gets a thumbs up:)

  17. Nice review.

    I’ve had 2 Nautilus 2 tanks and both have failed me! (both original, checked the codes).

    The first would not draw any air so every hit was dry and burned my throat. I wasted 3 coils in the process. The replacement did let air through – and also the liquid: it leaked like a sieve!

    Not happy and I really wanted this to replace the terrible Nautilus X tanks (I have 2).

    Sorry Aspire. You let me down on the latest 4 purchases. I may just go back to my Triton Mini. But now I’m Ā£100 down with nothing but worthless tanks to show for it. I won’t buy from Aspire again.

    • Sorry to hear that glen, sounds like you had a bit of a nightmare.

      I’m actually using the Nautilus 2 as I write, not had any issues so far.

      Without stating the obvious Glen (as you seem to have ample experience) did you make sure of the following:

      Was the airflow fully open?
      When filling, being careful not to get any juice in the coil head itself.
      Letting the coil sit for 5-10 minutes to allow the wick to fully soak up the juice.

      May be worth breaking the tank down and giving it a full clean and trying again? Although you sound like you’ve had enough at this stage!

      Can I ask what PG/VG ratio of juice you were using? I’m actually using Twelve Monkeys Tropika which is a 90VG/10PG and I’m actually surprised that such a high VG ratio wicks and works well in this tank. I thought it might have been too ‘thick’ for these coils.

      • Wow I was worried if it would be able to handle 70/30 or 80/20… 90/10 is wild. No issues at all after trying such high VG %?

        • I haven’t tried anything above 70VG in the Nautilus 2. 70VG was fine although you have to give the coil time to re-soak that juice in between vaping. 60VG/40PG is my preferred.

          • I’m confused then. The comment I replied to says:

            “Iā€™m actually using the Nautilus 2 as I write, not had any issues so far.”

            “Iā€™m actually using Twelve Monkeys Tropika which is a 90VG/10PG and Iā€™m actually surprised that such a high VG ratio wicks and works well in this tank.”

          • Ahh! Yes.. Sorry.. you’re quite right! Thanks for the reminder! That was a while back and used many tanks since, forgot I was vaping Tropika quite a bit! šŸ™‚

            It did work just fine with the 0.7ohm coil, I remember that I did have to adjust my vaping style sometimes.. ie: take it easy with the chain vaping and hold back a touch if you feel the cotton drying out and allow the juice to soak back into the cotton.

            I’ve reverted to 60VG – 70VG max since for regular vaping, just cuts down on the extra steps.

          • You said you were using 90/10 juice in the comment that I replied too, but then you replied to me saying you never used above 70/30. Was the 90/10 on a different device?

            Yesterday I replied and said I was confused about this and you people deleted my comment. Why would you do that when I am just trying to get some clarification?

          • Okay I see it’s something odd with your website. I checked your site many times yesterday and my reply was gone. After posting another comment just now the original showed up as “awaiting moderation” again.

  18. Don’t change… I love your reviews/style lol ?

    Besides I also find them v. helpful, this one prompted me to actually go and buy the Nautilus 2 and I’m loving it. Having used it for a week or so with the 0.7 ohm coil, I totally agree with everything you wrote. From the weirdly attractive bell end/buoy look of it to the awesome air flow and superb flavour. It’s currently attached to my Pebble (great combo)… I find I consistently reach for this over my Isub S even though I found that to be pretty damn good too.

    • Haha thanks very much – I have mine on the Pebble – right next to me now – and yup it’s a great combo. Glad you’re enjoying it šŸ™‚

  19. I use the nautilus mini since I stop smoking, a little more than a year.. Nice review cause you mention the airflow which was a little tight and or maybe I get bored with the old one

  20. I bought the Nautilus X about a week ago, and was initially impressed. However, after a few days, the flavour seemed diminished, and the coils didn’t seem to be robust enough (3 coils during the week). I now have the Nautilus 2, and I am, so far, impressed. Using the 0.7 coil at the moment, and I have to say that the vape is smooth, and the flavour is deeper than the X. I’ll give it a try for the next week or so, and swap to the 1.8 coil to see how that goes. FIrst impressions though, forget the X, and try the 2.

  21. I could have done without all the “lol” and “sez” throughout the entire article. The *multiple* childish names were a little annoying too. Other than that pretty nice review.

    • Not the first time it’s been pointed out I can be a little puerile and doubt it will be the last lol – point taken and I shall try to be a little more serious in my review style šŸ™‚ cheers!
