Key Takeaways
Overall Rating: 4.2 / 5 stars
- Seven PnP X coil options (0.15Ω to 1.0Ω) cover DTL, RDL, and MTL styles from a single tank — that range is genuinely rare at this price point
- The Golden Triangle Airflow structure produces noticeably richer, more layered flavor compared to straight-through airflow designs I’ve tested
- A 5 mL transparent tank with top-fill makes daily use genuinely convenient — you can see exactly when you’re running low without unscrewing anything
- The rotary air adjustment dial offers precise, visual airflow control that holds its position without drifting
- Coil longevity held up well across real-world testing, supporting Voopoo’s 100 mL claim under normal use conditions
One-line verdict: Worth it if you want a versatile, flavor-forward sub-ohm tank with wide coil compatibility — skip it if you’re committed to pod systems or want the absolute cheapest option on the market.
What Is the Voopoo UForce-X 2 Tank?
The first thing I noticed wasn’t the flavor or the airflow. It was the weight.
Picking up the UForce-X Tank II for the first time, I felt 64 grams of stainless steel and glass sitting solidly in my palm — not heavy enough to be uncomfortable, but substantial enough that you immediately know this isn’t a cheap piece of hardware. That reassuring heft was my first signal that Voopoo built something serious here.
This is my full Voopoo UForce-X 2 Tank Review, and I’ve been running this tank daily for over a week across multiple mods and coil configurations.
Who Makes It?
Voopoo is a well-established vaping brand distributed widely across the US market through retailers like Giant Vapes and AliVape. They’ve built a strong reputation around their PnP coil ecosystem, which has grown into one of the more versatile coil platforms available to American vapers. The UForce-X series is their flagship sub-ohm tank line, and the Tank II is its latest evolution.
What Does It Do?
The UForce-X Tank II is a 510-interface sub-ohm tank designed to work with any compatible mod. It runs on PnP X platform coils exclusively, covering the full spectrum from direct lung (DTL) at 0.15Ω all the way to mouth-to-lung (MTL) at 1.0Ω. That range is genuinely unusual for a single tank — most sub-ohm tanks don’t bother with MTL coils at all. If you’re still figuring out which style suits you, our guide on the difference between mouth to lung and direct lung inhale is a solid starting point.
Who Is It For?
This tank is built for experienced vapers who want flexibility without constantly swapping hardware. If you chase flavor, switch between vaping styles, or run high wattage builds, this tank was designed with you in mind. It’s not the right fit for beginners or anyone hunting the lowest possible price.

PnP X Platform & Coil Compatibility
Seven coil options across three vaping styles — all compatible with the same 510-threaded tank body — means you’re buying one piece of hardware that genuinely adapts to how you vape on any given day. The 510 interface also means it’s not locked to Voopoo mods. I ran it on two non-Voopoo devices without any fit issues whatsoever. If you already own a compatible Voopoo device like the VOOPOO Drag 6 or the VOOPOO Argus XT, this tank slots straight in with zero friction.
Golden Triangle Airflow Structure
Voopoo describes this as an “innovative airflow architecture” designed to deliver smoother airflow and more efficient atomization. In practice, the triangulated design channels vapor more deliberately through the coil rather than letting it travel a straight, unfocused path. You notice the difference most when running the 0.3Ω coil at 35–38W — the middle of its recommended range is where the flavor complexity really opens up.
5 mL Capacity & Top-Fill Design
Five milliliters is a solid amount for daily use. The glass tube is fully transparent, so checking your level takes a glance rather than unscrewing anything. The top-fill system works cleanly — flip the cap, fill, close. I didn’t experience a single leak during any fill session, which wasn’t always the case with older top-fill designs I’ve run over the years.
Rotary Air Adjustment Dial
This is one of my favorite mechanical details on the entire tank. The dial turns with consistent, light resistance — not too stiff, not so loose that it shifts accidentally in a bag or pocket. Because it’s graduated visually, you can see exactly where your airflow setting sits at a glance. Other tanks use sliding rings that can creep out of position. This dial stays put.
Build Quality & Materials
Stainless steel with a glass tube. The finish on the Silver version I tested was clean and consistent, with no rough edges or uneven machining. The glass sits securely inside the metal frame without any wobble. A spare glass tube ships in the box — a genuinely thoughtful addition that signals Voopoo knows its users.
My Experience
Setup & First Impressions
The US package includes the tank, two coils (PnP X 0.15Ω and PnP X 0.2Ω), a spare glass container, a silicone rubber pack, and a user manual. The coils were protected in their own packaging, and the tank arrived clean. I still recommend pulling whatever coil looks pre-seated and re-seating it yourself during initial setup — just to confirm the fit is solid before you fire anything.
I primed the 0.15Ω coil with a few drops of e-liquid directly on the cotton, let it sit for five minutes, then started at 60W before incrementally moving up. Breaking in a coil properly takes patience, but it pays dividends in longevity.
Flavor & Vapor Production
The Golden Triangle Airflow structure earns its name. With the 0.2Ω coil running at 50W and the airflow dial set to roughly two-thirds open, the flavor was noticeably layered — more so than I expected from a tank at this price. I tested with a fruit blend and a tobacco e-liquid. The fruit came through bright and clean without any muted edges. The tobacco had genuine body and depth that a flatter airflow design tends to kill.
Vapor production at DTL settings is dense and warm without crossing into harsh territory. At RDL settings on the 0.45Ω coil, the draw tightened up pleasantly and the flavor concentrated further. I was genuinely surprised at how well the same tank handled both experiences without any compromise between them.
Coil Longevity & the 100 mL Claim
Voopoo claims a single PnP X coil sustains 100 mL without flavor fading or burning. That’s an ambitious number. After running roughly 80–90 mL through the 0.15Ω coil during my testing week, I didn’t experience any meaningful flavor degradation or dry hits — provided I kept the tank above a quarter full. Let it run low, and you’ll get a dry hit. That’s user error, not a coil failure.
Airflow Control in Action
I’ve used a lot of sub-ohm tanks over the years, and most sliding airflow rings eventually develop that frustrating looseness where the setting drifts without you touching it. The rotary dial on the UForce-X Tank II is a genuine step up. The movement is smooth and predictable. You can close it down for a tighter RDL draw or open it fully for wide-open DTL, and the transition feels linear rather than jumping between states.
Leak Testing & Tank Integrity
I put the tank through deliberate stress — filling it, leaving it on its side for an hour, running it at wattages above the recommended range. No leaks under standard upright conditions across the entire testing week. One very minor seep appeared around the base after the on-its-side hour, but that’s not how anyone actually stores their tank. Under real use, it was dry every single time.
Compatibility & Versatility
The 510 connection worked without issue on every device I tested it on. Coil swaps took under a minute. Unscrew the base, pull the used coil, press in the replacement, reassemble. No tools, no threading issues, no frustration.
Minor Annoyances & Real-World Quirks
Here’s my genuine criticism: the 29mm tank diameter creates a noticeable overhang on mods with smaller top caps. This isn’t a minor aesthetic footnote — on a compact mod, the overhang looks awkward enough that it genuinely affects how the setup feels in hand. It’s not a dealbreaker if you’re running a full-size device, but if your daily driver is a compact mod, you need to know this before buying.
The top-fill cap also requires a firm fingernail to flip open. It’s not a one-thumb operation, especially if your hands are dry or cold. Neither issue affected performance, but both are worth factoring into your decision.
Pros and Cons
Pros
- Seven coil options in one tank — the PnP X range covers DTL, RDL, and MTL without needing separate hardware for each style
- The rotary airflow dial is the most satisfying airflow control I’ve used on a sub-ohm tank — smooth, visual, and it holds position
- Coil longevity holds up in the real world — the 100 mL claim is achievable under normal conditions, which translates to genuine savings on replacements
- Top-fill design is genuinely clean — not a single drop appeared anywhere it shouldn’t during normal use
- Spare glass tube included — small detail, meaningful value if you’ve ever cracked a tank mid-week
- Works on any 510-interface mod without adapters or fit issues
- The 5 mL transparent tank means fewer refills and instant level checks at a glance
Cons
- The 29mm diameter is a real problem on compact mods — this isn’t a minor cosmetic issue; the overhang affects ergonomics and looks wrong on smaller devices. If you run compact hardware, this is a legitimate dealbreaker.
- MTL coils aren’t included in the US package — the box ships with 0.15Ω and 0.2Ω DTL coils only, so MTL vapers need to budget for additional coil purchases immediately
- You’re locked into PnP X coils — no cross-brand compatibility, and legacy PnP coils from older Voopoo devices don’t work here
- The top-fill cap requires a firm fingernail to open — not ideal for one-handed operation or cold-weather use
- Flavor does degrade if the tank runs low — the 100 mL coil lifespan assumes you keep it adequately filled; neglect it and you’ll burn the coil before it reaches its potential
How It Compares
Choosing the right tank means knowing your alternatives. Here’s how the UForce-X Tank II stacks up against two strong competitors available to US vapers right now. For a broader look at the top options on the market, our roundup of the best vape tanks covers the full field.
| Product | Price (USD) | Best For | Rating |
|---|---|---|---|
| Voopoo UForce-X Tank II | ~$29–$35 | Vapers who switch between DTL, RDL, and MTL | 4.2/5 |
| Vaporesso iTank T | ~$28–$32 | Cloud chasers focused on wide-open DTL | 4.0/5 |
| SMOK TFV18 Mini | ~$22–$27 | Budget-first buyers focused on cloud output | 3.7/5 |
Voopoo UForce-X Tank II vs. Vaporesso iTank T
The Vaporesso iTank T is a capable sub-ohm tank with a strong track record among DTL vapers running high wattage. Cloud production is competitive. But it doesn’t offer anything close to the coil variety of the UForce-X Tank II — there’s no MTL option, and the airflow isn’t designed for tighter draws. If you want one tank that genuinely handles both DTL and MTL styles, the UForce-X wins that comparison. The iTank T matches it on raw cloud output, but nothing more.
Voopoo UForce-X Tank II vs. SMOK TFV18 Mini
The SMOK TFV18 Mini typically runs $22–$27 at US retailers — noticeably cheaper. It’s a reasonable budget pick for vapers who want cloud production without spending much. Build quality isn’t at the same level, though. Coil longevity is shorter, there’s no MTL coil option, and the airflow control lacks the precision of the rotary dial. If $10 is the deciding factor, the SMOK gets the job done. If you want consistent performance across more vaping styles and longer coil life, the UForce-X Tank II justifies the extra spend.
Who Should Buy This (And Who Shouldn’t)
Best For
- Style-switchers — if you vape DTL at home and prefer a tighter MTL draw out in the world, this is one of the very few tanks that handles both without compromise
- Flavor chasers who want vapor complexity, not just vapor volume — the Golden Triangle Airflow structure delivers layered taste that flat-bore designs can’t match
- Vapers upgrading from pod systems — the 510 interface pairs with any mod, and the wide coil range makes the jump from pod to tank far less jarring. Our guide to switching to vaping is worth reading if you’re at that crossroads.
- Anyone already in the Voopoo ecosystem with a DRAG 6, DRAG 5, ARGUS GT II, ARGUS XT, or ARGUS MT
- Vapers who’ve been burned by leaky tanks before — the 4-layer leak-proof coil design held up across every real-world test I threw at it
Skip This If
- You’re new to vaping — the coil range and wattage variables require some experience to navigate confidently. Start with a beginner vape kit first.
- Your daily mod is compact — the 29mm diameter overhang on a smaller device is a genuine ergonomic problem, not a cosmetic one
- You prefer pod systems and have no plans to run a box mod
- Budget is the only factor — there are cheaper tanks available, and they’ll do a job. This is the value pick, not the bargain pick.
Price & Value
Current Pricing & Availability
The UForce-X Tank II is available at several US retailers. Giant Vapes lists it at approximately $29–$35 depending on colorway, with domestic shipping typically arriving within 3–5 business days. AliVape also carries it with competitive pricing. You can grab it directly through this link if you want a straightforward purchase path. The Silver, Gun Metal, and Black colorways are all generally in stock.
Is It Worth the Money?
At $29–$35, you’re getting a stainless steel and glass build, a seven-coil ecosystem, a precision rotary airflow dial, and confirmed coil longevity across 100 mL of e-liquid. That’s a meaningful amount of hardware for the price.
It’s worth the money if you’ll actually use the coil range and care about flavor quality. If you’re only ever going to run one coil at max wattage and never adjust the airflow, you could spend less on a simpler tank. But for anyone who wants genuine versatility from a single piece of hardware, this price point is fair — and the coil longevity means you’ll spend less on replacements over time.
Deals & Discounts
Voopoo periodically bundles the UForce-X Tank II with devices like the DRAG 6 at a reduced combined price — typically the best value entry point if you’re buying both. Individual tank discounts appear on US retail sites during holiday sales and promotional periods. It’s worth checking Giant Vapes and AliVape before paying full price.
What Customers Say
Across verified reviews from Reddit’s r/Vaping community, vaping hardware forums, and US retailer product pages, the overall sentiment around the UForce-X Tank II was strongly positive — but not without recurring complaints. [1][2][3]
Positive Feedback Themes
Flavor quality was the most consistently praised aspect. Users described the experience as “clean and full” and repeatedly highlighted coil longevity as a standout feature over competing tanks. One forum reviewer noted the tank “keeps flavor consistent well past 50ml, which I couldn’t say about the older UForce coils.” [1]
The rotary airflow dial was frequently called out as a physical improvement over sliding ring systems, with several users specifically praising how it stays in position during daily carry. The top-fill design was described by multiple buyers as “the cleanest I’ve used without any dripping down the side.”
The Vaping Hardware review noted that the Golden Triangle Airflow “brings noticeably smoother, more complex vapor delivery” compared to the original UForce-X. [2]
Negative Feedback Themes
The overhang on smaller mods was the most common complaint — and it wasn’t treated as a minor issue by the people raising it. A Reddit commenter noted, “It’s a great tank but looks ridiculous on my smaller setup.” [3] That sentiment appeared repeatedly across different platforms, which confirms it’s a genuine design limitation rather than an isolated gripe.
A secondary complaint was the PnP X coil exclusivity — some users were frustrated that their existing PnP coil stock wasn’t compatible, requiring a full platform upgrade. Several US buyers also flagged that the package doesn’t include MTL coils, which caught them off guard when they wanted to test tighter draw styles straight out of the box.
Final Verdict
Overall Rating: 4.2 / 5 stars
After a full week of daily use across multiple mods and all included coil configurations, this Voopoo UForce-X 2 Tank Review lands clearly on the positive side — but with specific caveats that matter depending on your setup.
The tank delivers on its core promises. The Golden Triangle Airflow structure produces genuinely complex, layered flavor that flat-bore designs don’t match. The rotary dial is the best airflow control mechanism I’ve used on a sub-ohm tank at this price. Coil longevity held up under real-world conditions. The build quality is solid, the top-fill is clean, and the 510 interface means you’re not locked into any specific mod ecosystem.
The 29mm diameter overhang on compact mods is a real problem — not a footnote. And MTL vapers buying this in the US will need to spend more on additional coils immediately, because they’re not in the package.
Buy it if you’re an experienced vaper running a mid-to-large mod, you want a single tank that covers DTL through MTL, and flavor quality matters more to you than keeping costs at rock bottom. Pick it up here.
Skip it if you’re new to sub-ohm vaping, running a compact device, or need the absolute lowest price available. If you’re still figuring out what type of vape suits you best, the Vape Finder Quiz can help narrow it down before you commit to a tank like this.
This tank earned its place in my regular rotation. It’s the one I reached for most during testing week — and that says more than any specification table can.
