Two of the best vape tanks on the market right now (they’re both literally ranked inside our Best Vape Tanks Guide), and they’re aimed at completely different vapers. The Uwell Valyrian IV is a cloud-first beast with the biggest capacity in the Valyrian lineup. The Vaporesso iTank T is a cleaner, smarter daily driver built around convenience and flavour precision. Both are excellent. But they are not interchangeable.
Here’s the straight version of which one you should buy.
Specs Side by Side: What the Numbers Actually Mean
The 32mm diameter on the Valyrian IV is big. It’ll overhang on most single-battery mods. If you’re running a compact setup, that’s going to look odd and potentially rock on the 510 pin depending on your mod’s deck. The iTank T at 24.5mm fits clean on almost anything.
The 8.5ml capacity on the Valyrian IV is genuinely significant. If you vape heavily at high wattage, you can go most of a day without refilling. The iTank T gives you 6ml with the included bubble glass, which is still solid for a full day of moderate vaping.
Bottom airflow on the Valyrian IV means air comes in below the liquid level. That creates the conditions for leaking if seals degrade. Uwell’s self-cleaning leak-proof tech redirects condensation and largely solves this, but it’s a structural consideration worth knowing. The iTank T’s top airflow means liquid never has a direct path to the airflow inlets. Structurally, it’s the more leak-resistant design.
Uwell Valyrian IV Coil Performance
The V-Coil is the headline feature here. The 0.18Ω V-Coil running at 90-100W uses PRO-FOCS 4.0 technology with a large-area organic fibre structure for rapid wicking. The 0.35Ω option runs 55-65W and is the better pick for flavour-focused sessions. You get both in the box.
The pre-installed 0.18Ω V-Coil is one of the best stock coils I’ve seen at this size. Cloud output is comparable to an RDA at 90W+, and it doesn’t drink juice at the rate you’d expect for a tank this large. Coil lifespan runs around two weeks of steady use without high-sweetener juice.
One gripe: coil removal requires a twist rather than a straight pull. You get used to it, but it’s less intuitive than push-fit designs. The V-Coil platform is also backwards compatible with Valyrian II and III coils, which gives you some flexibility if you’re already stocked up.
The drip tip is proprietary. It doesn’t fit standard 810 or 510 replacements. If customising your setup matters to you, that’s a real-world frustration.
Vaporesso iTank T Coil Performance
The GTi coils use COREX 2.0 technology, which runs an upgraded morph mesh grid for more precise temperature alignment. In real terms: quicker heat-up, more even saturation, and better heat resistance from the cotton, which extends coil life.
You get the 0.2Ω and 0.4Ω GTi mesh coils in the box. The 0.4Ω at around 55W is my preferred daily coil. Warm vapour, strong flavour, and reasonable juice consumption. The 0.2Ω suits cloud-forward sessions but stays well below the Valyrian IV’s ceiling.
The GTi coil is a closed platform. It only works in Vaporesso tanks. In the UK, coil availability from major retailers is generally fine. In the US, you’ll likely need to order online rather than grab them from a walk-in shop. That’s worth factoring in before committing.
Uwell Valyrian IV Flavour Production
The Valyrian IV’s flavour is dense and layered. The larger heating surface area on the V-Coil saturates juice thoroughly at high wattage. On the 0.35Ω coil at 60W, flavour clarity is strong and the warmth enhances certain juice profiles, particularly fruits and desserts.
What it doesn’t do is give you the cool, clean flavour definition of a top-airflow tank. Bottom airflow draws warm air across the coil, which changes the profile. It’s not worse, just different. If you like a warm, full DTL hit with bold flavour saturation, the Valyrian IV delivers that better than most tanks at this price.
Vaporesso iTank T Flavour Production
This is where the iTank T wins the comparison. Top airflow keeps vapour cooler, and the COREX 2.0 morph mesh delivers more precise temperature alignment across the coil surface. The result is cleaner, sharper flavour with better definition between notes in complex juice profiles.
The 3D honeycomb airflow also keeps temperature consistent across sessions, so you don’t get the flavour drift that can happen with side-airflow tanks after extended chain vaping.
On fruity high-VG juice, the difference is noticeable. Notes are cleaner and easier to distinguish.
For vapers who prioritise flavour reproduction above raw volume, the iTank T has the edge here.
Uwell Valyrian IV Vapour Production
This is the Valyrian IV’s speciality. Running the 0.18Ω V-Coil at 90-100W produces dense, smooth cloud output at a level most sub-ohm tanks can’t match at stock.
The large coil surface area combined with the 8.5ml capacity means you can run extended sessions without throttling down or constantly reaching for the bottle.
For cloud-focused vapers, there’s nothing in this comparison that competes. The iTank T simply doesn’t operate in the same wattage territory.
Vaporesso iTank T Vapour Production
Solid, not spectacular. At 60-80W on the 0.2Ω GTi coil, vapour production is strong and satisfying for most vapers. Clouds are dense and consistent. But if your whole vaping identity is cloud output, this is not the tank that’s going to impress your mates.
What it does well is consistency. The self-circulating e-liquid system draws condensation back up into the tank, and the cool top airflow keeps vapour even across long sessions. No hotspots. No sharp flavour drop-off after twenty minutes of chain vaping.
Uwell Valyrian IV Ease of Use
The press-to-open top fill is quick and one-handed. The tank itself is straightforward to disassemble and clean. The coil twist-to-remove is the only ergonomic step that takes adjustment.
The big practical issue is size. At 32mm wide and 62.5mm tall, this tank is chunky. It’s a good fit on dual-battery mods like the VooPoo Drag 5 or 6, or the Aegis Legend 5. On a single-battery compact mod, it’s going to look and feel out of proportion. Pair it right and it’s a dream. Pair it wrong and it becomes a daily frustration.
Vaporesso iTank T Ease of Use
This is genuinely one of the most convenient tanks I’ve used. The slide-to-open top fill means you refill without removing the tank from your mod, one-handed, in seconds. The e-liquid self-circulating system keeps the bottom clean. The press-fit GTi coil installation is straightforward and fast.
One real-world gripe: the airflow ring has no stopper. It rotates freely all the way around, which means your airflow setting can shift in a pocket or bag without you noticing. It’s not a dealbreaker, but it’s the kind of thing you clock after a week of daily use.
The 24.5mm profile means it fits clean on anything from a compact pod mod to a full-size box mod. That versatility makes it a more practical choice across different setups.
Fun Fact: Vaporesso’s original iTank launched with 8ml capacity and a turbo airflow design, and quickly became one of the most recommended tanks for Vaporesso box mods. The iTank T is the “T” for top airflow, the biggest structural upgrade the line has seen.
Uwell Valyrian IV Price
Around $31.99 US at most major retailers. Verify current pricing with your preferred retailer before buying, as sale prices are common. UK pricing typically sits around £20-25 depending on retailer.
V-Coil replacement packs: check your retailer for current stock. The Valyrian IV V-Coils are backwards compatible with Valyrian II and III coils in a pinch, which gives you more sourcing options.
Vaporesso iTank T Price
Around $21.99 US at current retail, making it roughly $10 cheaper than the Valyrian IV. UK pricing typically lands around £18-22. The iTank T represents strong value for what it delivers, particularly given that the 6ml bubble glass upgrade and both coil options are included in the box.
GTi replacement coils are available from Vaporesso directly and most major UK retailers.

FAQ: Uwell Valyrian IV vs Vaporesso iTank T
Which tank has better flavor? The Vaporesso iTank T delivers cleaner, cooler, and more defined flavour thanks to its top airflow design and COREX 2.0 GTi mesh coils. The Valyrian IV produces strong, warm, dense flavour that works well at high wattage, particularly on fruits and desserts, but the iTank T edges it on clarity and note definition.
Is the Uwell Valyrian IV worth the extra cost over the iTank T? Depends entirely on what you vape for. If cloud output and maximum capacity are the priority, yes, the Valyrian IV justifies the extra spend. If you care more about flavour and everyday convenience, the iTank T is the better buy at the lower price point.
Can I use the Vaporesso iTank T on any mod? The iTank T uses a standard 510 connection, so it fits most box mods physically. It runs best between 40-80W. You’re locked into Vaporesso GTi coils, so availability from your usual retailer is worth checking before you commit.
Does the Uwell Valyrian IV leak? It performs well in real-world use despite using bottom airflow, which is typically the higher-risk design. Uwell’s self-cleaning leak-proof technology redirects condensation and significantly reduces leakage. Forum feedback across multiple months of use backs this up, with few consistent leaking reports.
What mods pair best with the Uwell Valyrian IV? High-wattage dual-battery mods with a wide deck. The VooPoo Drag 5 and Drag 6, Geekvape Aegis Legend 5, and similar 200W-capable box mods are the natural pairing. The 32mm diameter will overhang noticeably on compact or single-battery mods.
What mods pair best with the Vaporesso iTank T? The iTank T was designed for the Vaporesso GEN SE and GEN Max, and works best there. But at 24.5mm diameter, it fits clean on most 510-compatible box mods and performs well between 50-80W, so your options are broad.
