Uwell Replacement Tanks UK — Valyrian 2 Pro, Crown IV & Crown V

Skip to product grid

2 products

If you have been vaping for a while, you already know that a good tank matters just as much as a good coil. A tank controls how much flavour you taste, how big your clouds are, and how often you have to stop and refill. Uwell has built its whole reputation on making solid, dependable Uwell vape tanks that vapers actually trust, and on this page you will find three of their best sellers, all explained in plain simple language.

Uwell started out in Shenzhen back in 2015 and within just a few years it became one of the most respected names for tank technology in the whole vaping world. Here is a fun fact for you — Uwell was actually one of the very first brands to popularise mesh coil technology, and that same mesh design is now copied by almost every big vape brand out there today. So when you buy from this brand, you are buying from the people who basically started the trend.

📢 Two Things You Need to Know

  • Disposable Ban (1 June 2025): Single-use vapes are now illegal in the UK. Every legal device must be rechargeable with a swappable pod.
  • Vape Tax (1 October 2026): A duty of £2.20 per 10ml lands on nicotine-containing liquids. Stock up on tanks and coils now to save.

💡 The Truth About Tank Capacity In The UK

You will often see people searching for a 10ml vape tank or a 6ml vape tank, and honestly it is a fair question. Under UK TPD rules, every tank, pod, and cartridge sold here is legally capped at 2ml of e-liquid, no matter what the international box says.

The Valyrian 2 Pro ships at 8ml outside the UK. The Crown IV ships at 6ml outside the UK. The Crown V ships at 5ml outside the UK. Every version sold on this page fits a UK legal 2ml glass instead, which is why you may notice bigger numbers floating around elsewhere online.

Then we have the Uwell Crown V Vape Tank, priced at £26.99, down from £31.95. The Crown V is the upgraded version of the Crown IV, and it improves the fill mechanism with a silicone check valve that stops leaks even if the tank happens to tip over by accident.

Which Uwell Tank Should You Actually Choose?

Not sure which tank to pick? Here's our quick take:

  • Best for Cloud Chasers: Uwell Valyrian 2 Pro — 2ml capacity, 80-120W coils, hinged flip top, £26.99
  • Best Budget Pick: Uwell Crown IV — 2ml capacity, 60-80W coils, quarter twist top, £8.99
  • Best Everyday Vape: Uwell Crown V — 2ml capacity, 50-70W coils, silicone check valve, £26.99

 

How To Choose

If cloud size and long vape sessions matter most to you, go with the Valyrian 2 Pro. If you are watching your budget but still want great flavour, the Crown IV at only £8.99 is very hard to beat. And if you want a balanced, leak-resistant tank for daily use, the Crown V ticks that box nicely without any fuss.

All three of these are proper Uwell vape tanks built with the same core technology, and none of them will let you down as long as you match the coil resistance to the wattage your mod can comfortably handle.

 

Looking After Your Uwell Tank

Taking care of your tank properly will make it last a lot longer and taste a lot better too. Always prime a new coil by adding a few drops of juice directly onto the cotton before your first vape, and give it five to ten minutes to soak in properly before you fire it. This one simple step prevents dry hits and burnt cotton, which is the most common reason coils die early.

Try to keep your tank topped up rather than letting it run completely dry, and give the glass a quick rinse with warm water whenever you change your e-liquid flavour. Store spare coils in a cool, dry place, and replace them every one to three weeks depending on how often you vape and how sweet your juice is — since sweeter juices tend to gunk up coils faster.

 

Fun Facts About Uwell Tanks

  • Mesh coils — like the ones used in all three of these tanks — heat up faster and more evenly than old-fashioned round wire coils, and that is exactly why the flavour tastes so much richer and fuller.
  • Uwell's self-cleaning system was actually patented by the company, so you genuinely will not find the exact same technology built into rival tanks from other brands.
  • The word "Valyrian" was chosen to sound powerful and mythical, matching the tank's reputation for producing some of the thickest clouds in the sub-ohm category.

 

Frequently Asked Questions — Uwell Tanks

What is the difference between the Uwell Valyrian 2 Pro and the Uwell Crown V tank?

The main difference comes down to capacity and purpose. The Valyrian 2 Pro is built for big cloud chasers who vape at higher wattage (80-120W), while the Crown V is designed for a smoother, more controlled direct-to-lung experience at lower wattage (50-70W). Both share the same self-cleaning technology but suit different vaping styles.

How often should I change my Uwell tank coil?

Most vapers get around one to three weeks out of a coil, though this really depends on how much you vape and what juice you use. Sweeter e-liquids with more sugar content tend to gunk up coils faster, so you may need to change them sooner. Once you notice a burnt taste or reduced flavour, it is time to swap the coil out.

Can I use the Uwell Crown IV coils in the Crown V tank?

No, the coils are not interchangeable between the two tanks even though they look fairly similar. The Crown IV uses its own SS904L and UN2 coil range, while the Crown V uses a newer coil series designed specifically for its base and airflow system. Always check the product listing to confirm which coil series matches your tank before buying replacements.

What is the tank capacity of the Uwell Valyrian 2 Pro?

The Uwell Valyrian 2 Pro Replacement Tank holds a 2ml capacity in the UK (TPD compliant). The international version ships with 8ml glass, but every UK version sold on this page comes with the smaller, fully legal 2ml glass.

Is the Uwell Crown IV tank good for beginners?

Yes, the Crown IV is a great choice for beginners moving into sub-ohm vaping because it is affordable, reliable, and easy to fill and maintain. The included coils cover a gentle wattage range (60-80W), so new vapers can ease into bigger clouds without jumping straight into extremely high wattage setups.

Do these tanks fit on any vape mod?

All three tanks use a standard 510 threaded connection, which means they will physically screw onto the vast majority of box mods and regulated devices on the market. That said, always check your mod can handle the wattage range of the coil you plan to use, especially with the higher-powered Valyrian 2 Pro coils (up to 120W).

What is Pro FOCS technology?

Pro FOCS stands for Pro Flavour Optimised Core System, and it is Uwell's own technology used across the Crown and Valyrian ranges. It works by carefully controlling the heating temperature and airflow around the coil to bring out the truest flavour from your e-liquid, rather than just producing bigger clouds with less taste behind them.

Why is my Uwell tank leaking?

Leaking is usually caused by a loose top cap, a damaged O-ring, or filling the tank too quickly and flooding the coil. Make sure every seal is seated properly when you reassemble the tank, fill slowly, and avoid overfilling past the marked line. If leaking continues, check the glass for cracks or replace the O-rings, since worn seals are a common culprit.

What wattage should I vape at with the Crown IV coils?

The 0.4Ω coil performs best between 60 and 70 watts, while the 0.2Ω coil is rated for 70 to 80 watts. Starting near the lower end of the range and slowly increasing the wattage is a good habit, since it lets you find the sweet spot for flavour without risking a harsh or burnt tasting hit on a fresh coil.

Is there a Uwell Valyrian 3 or Valyrian 4 tank available?

Plenty of people search for a Uwell Valyrian 3 or Uwell Valyrian 4 hoping to find a newer release, but as it stands the Valyrian 2 Pro is currently the flagship cloud tank in this lineup and it is what we stock. It carries the same big cloud, high-capacity spirit that made the Valyrian name so popular in the first place.

Which Uwell tank gives the biggest clouds?

The Uwell Valyrian 2 Pro is the clear winner for cloud production thanks to its high wattage coil options going all the way up to 120 watts and its wide bore 810 drip tip. If dense, thick clouds are your main priority, this tank is built exactly for that purpose and will not disappoint cloud chasers.

How do I fill my Uwell tank without spilling juice?

Hold the tank upright, open the top fill mechanism fully — whether that is the hinged flip cap on the Valyrian or the quarter turn cap on the Crown tanks — and pour slowly down the side of the glass rather than straight into the centre. Avoid filling past the marked juice line and always avoid getting liquid into the centre airflow tube.
