The Aspire Odan sub ohm tank is bound to raise a few eyebrows with its unconventional and somewhat different approach to glass tubing.Aspire Odan Sub Ohm Tank Review

Over the last six years, Aspire have certainly released their fair share of tanks whether designed for the virgin vaper or the mainstream direct to lung user.

The Nautilus 2s, Triton, Tigon and renowned Cleito spring instantly to mind as do the K range of tanks and their CE5 clearomizer for the purest of mouth to lung experiences.

Simplicity has played a large part in the success of a company that has a knack of producing designs of mass appeal and appearance.

Lately there has been some tough competition in the sub ohm tank market with the likes of the OFRF nexMesh, SMOK TFV16 and of course the Horizontech Falcon King all jostling for your hard earned cash. It’s all about the expectation.

You’re about to find out if the Aspire Odan can sit with the best sub ohm tanks with my honest and unbiased review. Let’s cut to the chase..

What Can We Expect From The Aspire Odan Sub Ohm Tank?

The Odan Sub Ohm tank comes in two distinct versions, both offering TPD and non TPD compliancy. There’s the standard version (I’m reviewing the non TPD version) and the mini version which comes as 25mm in diameter and a height of 57.5mm making it actually taller than its big Brother.

The 2ml TPD Version doesn’t appear come with the diamond design glass.

The colour schemes available are Dark Blue, Emerald, Rainbow, Stainless Steel, Smoky Quartz and Black. Each variation has a drip tip to compliment.

Aspire tell us that the diamond cutting technology employed on the glass section is designed to offer improved heat resistance over traditional glass. The included mesh coils are comprised of 20% organic cotton and 80% linen fibre offering a slower, more efficient rate of wicking.

The main body of the tank is comprised of PVD (Physical Vapor Deposition) which should make it stronger and more durable during everyday use. Meanwhile the Odan utilises a special airflow channelling system to ensure an instant cloud and flavour hit.

Aspire also include an integrated shut off valve to prevent liquid entering the coil chamber when swapping coils out, making it a leak free experience.

This product was sent for the purposes of review, thank you Aspire. As always this will in no way alter my thoughts or opinions.

Design And Build Quality

When I first lifted the Odan out of the box the first thing to strike me was the apparent weight of this bad boy! Around 120 grams in the hand making it very substantial.diamond glass Tube

The second thing to hit home was the amazingly intricate work on the diamond cut glass tubing!

Glass Tube ( A cut above the rest)

I received my review model in the rainbow colour scheme which I’m not normally a big fan of. Aspire have decided to colour code the inner chimney which really does give off an extremely impressive effect.Odan tank colour options

It’s certainly bound to raise a few smiles of approval among those of a more outgoing, extrovert nature. In the words of the Wife, “It’s just like looking through a stained glass window”.

The intricate cutting and bevelling of the glass tube really does catch the light in a very sparkling manner adding to its appeal. Although only 5ml in capacity, it somehow feels more and that’s probably due to the doming.

Replacing Glass Tube

  • Remove the top cap by unscrewing counterclockwise.
  • Pull the glass tube up and free of the O ring seal on the deck.
  • Firmly seat a new glass section onto the O ring seal of the deck.
  • Screw the top cap back on with a clockwise motion. Do not over-tighten!

Drip Tip

Comprised of resin for added heat resistance, the 810 drip tip is available in six different colours designed to match the scheme of your chosen tank and has a pleasant honeycomb effect.810 replacement o ring colours

It incorporates two O rings of its own so don’t expect any old replacement to fit here.

Top Cap

Aspire have utilised their infamous “lift to fill” mechanic with the Odan sub ohm tank and we’ve seen the same technique used on the likes of the Tigon, for example.

How To Fill The Aspire Odan Tank

  1. Locate the arrow on the top cap.
  2. Grab the sides of the top cap to lift lid.
  3. Gently push backwards following the direction of arrow to expose fill port.
  4. Carefully squeeze E-liquid into tank.
  5. Pull the top cap back into place.
  6. Push down firmly on top cap to secure into place.

This is a very silky smooth operation, the tolerances being set to just the right level. Being a larger tank makes it that little bit easier to carry out too.

Chimney And Coil Placement

The Inner chimney of the Odan extends the theme used on the 5ml glass. It has diamond cut outs that allow the “plug and play” coils to line up with when inserting.

Simply push the coil up and into the chimney.

How To Change the Aspire Odan Coil

  1. Unscrew the base of the tank anticlockwise.
  2. Push the coil up and into the chimney while aligning the wick ports.
  3. Screw the base firmly back into position with a clockwise motion.

Aspire have incorporated a shut off valve which means it is possible to change a used coil mid tank avoiding that dreaded feeling of juice loss. Nice touch!

Bottom Airflow

There’s some substantial knurling featured on both the top cap and bottom airflow ring to facilitate ease of use.

It’s a piece of cake making the finest of adjustments thanks to some buttery smooth tolerances and three very sizeable cycloptic airflow slots featuring stoppers on either side.

As usual, what you change on one side will be mirrored on the other.

O rings

A special mention here for those often under attack! The O rings on the Aspire Odan are up there with the very best I’ve had the pleasure to work with.

O Ring Quality
A very strong O ring secures the glass tube to the deck.

The beefy one that secures the glass section to the base of the tank is especially effective in its sealing qualities. In all other areas of use they work pretty much perfectly.

How Does The Aspire Odan Sub Ohm Tank Perform?

The tank came with the 0.3ohm mesh coil preinstalled so that’s where we will begin.

0.3ohm Mesh Coil – Aspire Recommend 35-45W

Aspire Odan 0.3ohm replacement mesh coilThe output rating for the coil is stated as being between 35-45W so I decided to carry out my initial test slap bang in the middle at 40W.

As the rating for both coils were relatively low I felt comfortable enough to use my SX Mini SL Class single 18650 battery mod in partnership with the Odan…

Not exactly “matchy matchy” so please excuse some of the included pics if easily offended!

The juice of choice was Riot Squads Smashed Apple Pie, a 70VG/30PG ratio and one the coils should have no problem keeping up with.

(NB: The SX Mini SL Class was running on “Standard setting” to emulate the majority of box mods currently on the market)

Airflow wide open – No restriction

This offers an incredible amount of airflow with the very slightest touch of restriction but all I generally get is a taste of sweet nothing on the exhale and poor flavour quality all round.

Airflow Half open – Semi restrictive

A marked difference is observed over no restriction and some of the buttery back notes and traces of cooked apple are starting to appear while the cloud production remains as thick, dense and as satisfying as that of no restriction of airflow.

Airflow over three quarters closed – Restrictive

This is certainly a restrictive lung hit as the vape becomes warmer allowing the apple notes to fully shine through.

It’s now all systems go with those bakery elements really turning the profile into the apple pie experience I’ve come to know and love.

0.2ohm Mesh coil – Aspire Recommend 50-60W

Aspire Odan 0.2ohm replacement mesh coilThe recommended power setting for this coil is 50-60w so once again I went straight down the middle and tested at 55w. This time vaping Riot Squad Strawberry Scream with a 70VG/30PG ratio.

There was a noticeable difference in performance between the two coils.

Aspire Odan 7ml glass
The 7ml glass tube was used to test the 0.2ohm mesh coil

Airflow wide open – no restriction

I was instantly able to pick out the punchy fruit theme of this profile and a pleasing degree of creamy texture on the exhale. A very good start.

Airflow half open – semi restrictive

A more concentrated flavour was experienced on this setting with just a touch of a throat hit as cloud production became suppressed but still really chucking , ’em! The strawberry theme was coming to life.

Airflow three quarters closed – restrictive

The strawberry had become much sweeter while the cream notes made way for a more candy like, single flavour profile. The extra restriction was also warming the vape in an appealing way.

At no point during the testing of the 0.2ohm coil did I feel that it was under performing.

It was able to produce very bright and clean flavour across all three airflow settings, something the 0.3ohm coil was lacking slightly.

So no prizes for which one I preferred!

Unfortunately whatever setting you decide to employ, the Aspire Odan tank is noisy and prone to whistling on the less restrictive airflow settings.

Across the board you won’t be able to lose that “wind tunnel” effect which is disappointing because it distracts from an otherwise enjoyable vaping experience.


  • Easy fill top slide mechanism prevents leaking.
  • Convenient “plug and play” coils make swapping out very easy.
  • Lower coil wattage means increased battery life.
  • Exceptional flavour output ( Especially 0.2ohm mesh coil).
  • Substantial knurling for airflow adjustment as well as top cap removal.
  • Very good O ring tolerance and performance.
  • No leaking experienced from airflow ports.


  • 0.3ohm mesh coil lacks flavour when airflow fully open.
  • A loud tank that occasionally causes whistling.
  • The diamond cut glass. (won’t be for everyone – subjective con).

Final Verdict

Having spent enough time with the Aspire Odan tank there’s very little to knock.

Aesthetically it’s very pleasing on the eye. As much as the diamond cut design of the 5ml glass looks classy and elegant especially in direct sunlight, it still remains more of a talking point than of practical use.

For this reason I found myself using the straight 7ml version which in all honesty is far better suited to the SX Mini SL class single battery tube style mod.

The top cap slide mechanism works like a dream and is compatible with most nib variants to ensure a leak free fill. Both threading and O rings are manufactured to a very high standard. The large one situated in the deck is especially good because you can almost hear the suction as it grips down on the glass tube.

When chain vaping, the tank at best feels only warm to the touch, substantiating Aspires claims of heat resistance although it should be noted that maximum output tested was 60W.

Hardly pushing things compared to other sub ohm tanks of this ilk.

The airflow control ring works perfectly allowing you to dial into a direct to lung preference of choice. It didn’t take long for me to find my favoured restrictive setting and offered me terrific flavour, especially with the 0.2ohm mesh coil.

Coil performance

The coils themselves worked very well although the preinstalled (0.3ohm) had me doubting the validity of linen as a choice of wicking material.

They were also both running well below 3.7V at their maximum output recommendation.

Still, the flavour and cloud output provided by the Aspire Odan tank easily matches that of the Horizontech Falcon King, pound for pound.

I’ve thrown liquid ratios of 50VG/50PG at the tank and it refuses to leak!

I’ve thrown high VG DIY juice in it, again it kept up with no signs of a dry hit.. Even my own creations tasted good in this tank and that’s saying something!

I can only conclude that the linen material included plays a very important role in soaking up the e-liquid. This makes for a very consistent and reliable performance.

Each coil will last around 7-10 days if using juices with plenty of sweetener. They are also more than capable of replicating good flavour when switching profiles. Stick to ratios of 70VG/30PG with less sweetener and expect anything up to two weeks shelf life.

So would I recommend the Aspire Odan? If you’re already into sub ohm vaping and want to increase battery life without sacrificing flavour and cloud production, then yes! This a tank you should really be considering. Keep in mind however that it’s a bit of a beast. Make sure you have a mod that’s capable of handling the above average diameter.

My name is Neil and I've been a keen vaper for eight years, having been smoke free since 2014. That's all thanks to being introduced to a CE4 clearomiser by a work mate. In 2015 I started a Facebook group encouraging members to help others make the switch, sharing thoughts and opinions while acknowledging all the hard work that goes into running a vape shop and the guidance those folks give. I've also created a You Tube channel, Ncboreas Vapes. It's primarily there to help the newer vaper so if you've any questions feel free to drop by! There are so many positives to vaping and absolutely none to smoking. It's a message I continue to spread. Long Live Vaping. Live Longer Vaping.

aspire-odan-tankThe Aspire Odan does an impressive job. The flavour and cloud production is fantastic for a sub ohm tank while the coils can easily cope with all types of juice ratios. Plug and Play technology means fast replacement of coils, even with juice in the tank. Look beyond the somewhat noisy vape and you're rewarded with a tank that performs with the best of 'em. Highly recommended to the seasoned sub ohm vaper among you!


  1. Finally! I thought I was going mad when I tried my blueberry cake on the 0.3ohm coil, as I couldn’t get the notes. I was getting deep saturated notes on my Aegis Boost, but nothing on the odan 0.3ohm. Then I read your review. Now I’m following this site. That’s what I want no bs, all that hype and I was gutted until I tried the 0.2ohm.

    • Thanks for the kind words, Bruce!
      Every reviewer here at goes the extra mile to ensure a full and unbiased opinion. There was a distinct difference between the two sub ohm coils which obviously warranted a mention. It made my day to know you’re now following us! That’s very much appreciated so thanks again.
      Stay Safe!

    • In all honesty I’ve not tried the Cleito Pro, Jonathan but put against the Cleito 120 it performs better with a brighter, crisper flavour. Could be due to the linen used for wicking. Also doesn’t leak like the Cleito 120 does. Build quality is also improved. Just a shame about the lower wattage recommendations although it doesnt affect performance unduly. The 0.2 coil is superb..

      Thanks for taking the time to read the review. 😁

  2. It’s nice to see that Aspire are back into the true pioneering mode again, the glass isnt going to be for everyone but is sure as hell unique, I like this review. Good Job Neil. GV

    • It’s Aspire at their most innovative, Terry! The wick port locking mechanism is the first one I’ve come across. It means life is easy when switching out coils mid tank. As for the diamond cut glass? Mmm. As I wrote it won’t be for everyone but when it glints in the light is a thing of real beauty and if anything is a talking point. lol
      Thanks for taking the time to read and comment, my friend. Thanks also for those kind words.

      Kind regards,

  3. You can still get great flavour and cloud production with these coils. I was dubious at first about the linen fibre material combined with relatively low power output but it seems it does actually help with overall performance.
    Thank you for taking the time to read and comment, Scott.

    Kind regards,

  4. So they have taken the idea of voopoo with the Matt tank and have made the same thing with a stylish glass but not as powerful coils
