Has Uwell Stopped the Crown from Slipping Even More?

Uwell are hoping the Crown 3 tank will once again make them the right royal choice for sub ohm vapers.

The original Crown has gone down in legend as one of the very best tanks ever made – whilst the Crown 2 was pretty much forced to abdicate from its throne by a vapers revolt given the flavour was shall we say more peasant than pleasant.

Uwell Crown 3 reviewedSo with a brand new coil and brand new push and pull system to swap them out – and a fancy coloured band to crown things off – has Uwell regained the royal seal of approval?

Let’s stop with the really really bad metaphors and take a look at what the Uwell Crown 3 has to offer.

For the record I received the none TRPR/TPD compliant version coming in at 5mls – there is an EU friendly version the Crown Mini which comes in at 2ml.

As always my thoughts and opinions are my own.

Inside the Box

The Uwell Crown 3 vape tank comes in one of those tough plastic boxes with everything neatly packed away inside.

This is NOT the TRPR/TPD compliant version – this is 5ml.

The EU version is called the Crown 3 Mini and has a 2ml capacity and will be available in the UK soon, if not already, depending on when you read this review.

Crown III Quick Start Guide

OK when you first receive the tank you’ll need to unscrew the base to pull the coil out in order to prime it.

The coil is press fit so there’s nothing to unscrew once you’ve got the base off just pull it out.

crown III coil swap

  • Remove the coil and drizzle a little bit of e-liquid on the exposed cotton and push the coil back in screwing the base back on.
  • Remove the top cap and fill via the juice ports. Ensure your airflow is closed while filling.
  • Leave for at least 5minutes before vaping to allow the cotton to become soaked.

Cleaning the Tank

The tank can be fully taken apart from cleaning and maintenance however just like its predecessor there is a ‘locking ring’ under the top cap that you’ll need to unscrew and remove.

This is where that little Crown tool comes in – line up the slots and unscrew – the tank can then be taken apart.

Strangely the tank can be used without the locking ring and should you lose the little tool it can be opened with a suitable screwdriver.

Key Features

There’s not much difference in looks from the other versions however you’re looking at a slightly larger diameter than the not so well received Crown II measuring up at 24.5mm.

And of course the funky colour band around the 510 drip tip [which can be swapped out] makes for an eye catching feature.

But it’s the complete re-working of the coils that’s key here.

Gone is the old screw in style replaced with the simple push ‘n pull which seems to work well.

The bottom airflow has been redesigned with two large slots that are fixed [they don’t spin right round baby] and have a nice resistance to them.

As I mentioned I did own the original Crown sub ohm tank but it seems to have gone to that lost zone in everyone’s home where single socks go – in other words I can’t find it anywhere lol so actual comparisons are difficult.

There are just two coils out at the moment and no word from Uwell as to if or when a RBA deck might be released – though experience shows they do take their time 😉

Design and Build Quality

As you might expect the build is excellent with maybe the top cap being a little scratchy to take on and off.Uwell crown 3 review

I’ve been using this close to 2 weeks and haven’t had any threading issues as such – it just feels a little ragged so not sure if that may become an issue further down the line.

crown III components

I’m also not that keen on the ‘locking screw’ – why they feel the need to add that I don’t know and it does make taking the tank apart a bit of a bind.

You can vape without it, however, the airflow changes giving a much airier vape with maybe a little loss in flavour – more on that later.

Design wise and despite this being the 5ml version it doesn’t look that long on a mod – indeed Uwell seem to have been able to keep its length down so it doesn’t tower over the squatter mods out there.Uwell Crown 3 on limitless mod

There are plenty of colour options too with Sapphire Blue – Matte Black – Black – Rainbow and Stainless Steel which is the one I received.

The colour of the band on the drip tip depends on the colour of the tank you choose with mine being a quite regal green.

The central chimney has a very RTA look about it and the engraving on the top cap is nice without being obtrusive and the knurling on the base matches with the III detail.

All in all it’s a nice looking tank looking good on my devices.

How Does the Uwell Crown 3 Perform?

The first thing I have to say is on using both coils there was very little – read if any – break-in time for the coils and this is a real positive for me!

I’ve lost count of the amount of sub ohm stock coils that can take 2 or 3 tank fills before you get a decent flavour – with both these coils I had no such issue.

In fact the flavour I’m getting is absolutely stunning and then some!

Those of you who vaped on version 2 might be from the camp that said the flavour was not so good – all I can say about the Uwell Crown 3 is that they have nailed the flavour with these new coils.

However, I think they’ve been a little shall we say ‘conservative’ on the recommended wattage for both of them as they can take a touch more power without blinking!

I’ve been using quite a sweet lemony e-liquid and after at least 20 tank fills there’s no loss in flavour whatsoever I so I reckon these coils can maybe take some hits before needing to be replaced.

0.25 ohm SUS316 Parallel Coil 80 to 90W

At the low end the flavour is good however the vapour is wishy washy to say the least.

At 90 watts the flavour is intense – really intense – with a nice warmth to it and the vapour does crank up a little but this isn’t a cloud chaser!

At 100watts – over the max – the taste surprisingly stayed strong with the merest increase in temp – and as you might expect the clouds were thicker though still not epic.

I did go to 110 watts but whilst I had no bitter burn taste I could instinctively feel it was too much.

0.5ohm SUS316 Parallel Coil – rated for 70-80W

At the low end again the flavour was excellent and again the vapour was more of a mist than a fog.

80 watts brought the tank to life a little with the flavour increasing significantly but again the vapour whilst OK was not superb.

Pushing this coil to 90 watts – over its max – and again things perked up with a pleasantly warm vape great taste and half decent clouds.

What I Like

I love the flavour I’m getting off these new style stock coils – it’s knock your socks off good!

I like the design and look of the Uwell Crown 3 tank too and like I said even as a 5ml monster it doesn’t seem to tower over my mods.

Speaking of design I do like that fancy coloured band on the drip tip – it’s little details like that adds something in my opinion.

The airflow is excellent making a real difference to your vaping style and even with my preferred wide open the flavour is intense with a lovely cool airy vape.

Close those off a touch and flavour absolutely pops off your taste buds.

And I do like the simple push ‘n pull coil swap method and yes you can replace the coils with e-liquid in your tank and it is relatively ‘clean hands’ too.

When I’m writing I tend to chain vape and I did notice the tank whilst getting a little warm after half a dozen pulls in quick succession it doesn’t get uncomfortably hot.

After all the RTAs – RDTAs and RDAs I’ve been using recently I’ve enjoyed a pretty much leak free vape experience off the Crown 3 which I have to say has been nice lol.

Daft as it sounds the addition of a top cap cover – that yellow thing – is a nice touch and will keep debris and creepy crawlies out of your spout 🙂

What I Don’t Like

The fill ports are a little small and I have noticed the larger nozzles can leave a little juice under the top cap which can seep through once screwed back on if you forget to wipe it off.

Not a major issue if you have a small nozzle [as I tell all the girls] but something to bear in mind when filling.

Uwell also recommend closing the airflow when filling – as is recommended for most tanks – and yes I did get a tiny drizzle of juice once by filling whilst left open – not a lot but again something to bear in mind.

As to the ‘tank locking ring’ it is what is is – maybe a little over engineered and maybe a little fiddly taking on and off but as I’ve said you can vape without it – you may just notice a slight change to the airflow and tiny dip in flavour.

Final Review Verdict

The original Crown sub ohm tank was one of the most popular tanks ever made with vapers absolutely loving it.

We can draw a line through the second one given it received more than a few negative reviews however with the Crown III Uwell has a winner on their hands.

The flavour from this tank is exceptional – beating the new Cleito EXO hands down and that’s saying something.

Whilst the cloud chasers might be a little miffed the flavour chasers are going to absolutely love this – the flavour pings off your tongue right through the low to high settings – it’s bloody awesome!

So it’s safe to say I would buy the Uwell Crown 3 if it decided to join it’s big brother in the vaping abyss!
