The Crown 4 vape tank has been designed by Uwell, part of the Crown Tank series it has been designed to produce large clouds and flavour alike, thanks to its sub ohm coils it is compatible with high VG eliquids and has a 2ml max capacity. We recommend this vape tank for intermediate to advanced users.

The 510 connection allows you to use it with a range of vape devices, designed for sub ohm vaping we recommend higher powered devices. The Stainless Steel construction makes it very durable yet still lightweight.

A secure threaded top fill mechanism makes refilling a quick and clean task, removing the cap will reveal two large juice ports which fit most bottle nibs including the larger unicorn bottles. The seals throughout the filling and glass sections make the Crown 4 virtually leak-free

Offering large cloud and flavour production from eliquid, you have full control over the flow of vapour thanks the adjustable triple bottom airflow. Meaning you have the option of a restricted inhale or a breezy direct to lung vape. The 510 drip tip ensures a cool vape.

The newly designed Crown 4 Coils all feature a ‘plug and pull’ fitting, meaning changing your coil doesn’t require you to empty your tank and is quicker overall. The SS904L features a vertical coil structure and features a fast ramp up. The Double Helix coil features a mesh coil build for improved flavour.

Important information about sub ohm vaping:

This vape tank is intended for sub ohm vaping. Sub ohm tanks require a greater amount of knowledge and experience to use safely. They use specially designed sub ohm vape coils that register below 1.0 Ohm resistance, for use at higher wattages.

We recommend that when sub ohm vaping, you do not use an e-liquid that has higher than a 6mg nicotine strength, this will be too harsh on the throat. Sub ohm vaping produces more vapour and because of this, an increased throat hit. You should pair tanks like this with a high VG e-liquid, that is 60% VG or higher.


The 2ml Uwell Crown 4 is a sub ohm vape tank which features a triple adjustable bottom airflow.
With a sleek triple adjustable airflow, the Uwell Crown 4 is a high performing yet versatile sub ohm vape tank.
The 2ml Uwell Crown 4 sub ohm vape tank employs the Uwell Crown 4 vape coils available in 0.2 Ohm and 0.4 Ohm variants.
Utilising the Crown 4 vape coils which are available in a range of resistances, the Crown 4 vape tank allows users to configure their ideal vape.
The Uwell Crown 4 sub ohm vape tank features a threaded removable cap for a fast and effective refill method.
To refill the Crown 4 vape tank, simply unscrew the drip tip top cap and fill the juice port with e-liquid for an easy and hassle-free process.

Just couldn’t take to it (15 February 2020)

It’s okay and that’s about it for me. One thing I don’t like and have never liked it is the coil wattage being completely off what’s recommended. Some people have said they took it over 30 watts the recommended wattage. Too complicated for to find the sweet spot and never really had one to be honest. Nunchuku is better

The best tank (15 August 2019)

I bought this tank a fair few months ago now, and as I've been through many different ones, I wanted to wait to do this review until it had gone through alot of vaping hours. I must say I'm really impressed. It's still working as good as the first day I brought it. Hard-wearing, great flavour and cloud production and the coils last a long time providing there looked after properly. I give the product a solid 10 out of 10 all the way. If your looking for a excellent tank buy this one!

Great tank (02 May 2019)

Upgraded to this from the old school crown 1, using with the mesh coils.
Flavour is excellent, tank was easy to put together, doesn't leak and it looks a lot smarter and compact on my mod.
One small gripe is that the spare glass isn't the 5ml bubble so you have to cough up extra for one unless you're happy with 2ml.

Excellent tank (17 April 2019)

Probably one of my top 3 favourite tanks on the market for flavour. The build quality is excellent and probably the best of my top 3 but produces the least clouds compared to the other 2. Operation of the tank is like no other in its price range and catagory, silky smooth. This tank also very rarely, if ever, leaks. If leaking is your biggest annoyance then this is definitely the tank for you.

Great tank (15 April 2019)

This has to be my second favourite tank by Uwell, the only downside for me is the coils not being suited for high wattage.
Great flavour and great tank all round.

Awesome! (06 January 2019)

This tank, especially with the mesh coil.. Amazing.. Its a juice drinker tho!

By Benzil from RUTLAND

God I love a crown! (29 December 2018)

Bought this as I was in love with the v1. This does not disappoint at all. Considering there not mesh coils in the box the flavour is really good.
