Just the mod. Vaporesso GTX 18 Tank sold separately. Runs any 510 tank up to 40W. Been out long enough that there's a proper record of how it holds up — and it holds up well.
Overview
Pick it up and the first thing you notice is the weight. 83 grams. Smaller in the hand than it looks in photos. The anti-scratch coating covers most of the body — doesn't feel plasticky, doesn't pick up fingerprints the way bare metal does. Six colours: Black, Silver, Red, Blue, Green, Pink.
Two output modes: One's manual — you set the wattage yourself between 5 and 40W. The other is Smart Mode, which reads the coil resistance and picks the wattage for you. Smart Mode gets most coils close enough to the right wattage that you wouldn't bother overriding it. If you run multiple different tanks, that saves a lot of fiddling. Some people never touch manual mode after the first day.
Screen is 0.69 inches: Tiny but readable. Shows what it needs to — wattage, coil resistance, battery level. No touchscreen, no complicated menu. Three clicks gets you into wattage adjustment, five clicks turns it on or off.
2000mAh built-in battery with USB-C at 2A: About an hour to charge from flat. At MTL wattages it'll last most people all day — crank it for sub-ohm DTL use and you'll be reaching for the cable by mid-afternoon.
One gripe you'll see mentioned: the GTX Tank 18 fill port is a bit awkward to use. That's a tank issue. The mod itself scores 9/10 consistently across reviewer sites that have put time into it. Nobody's really got much to say against it.

Key Benefits
Smart Mode is genuinely good. Not all mods have it and the ones that do don't always get it right. This one does.
22.7mm wide. That's narrow. Goes in a pocket properly rather than just technically fitting.
510 connection, so you're not stuck with Vaporesso coils range — whatever tank you already own, it'll likely run on this.
The build quality at this price is better than expected. Anti-scratch coating actually works. Two reviewers tested it for months of daily carry and didn't have complaints about how it looked after.
2000mAh is enough for all-day MTL. Not enough for all-day 40W sub-ohm blasting. Know which one you are before you buy.
Setup
Charge it via USB-C first. Attach a 510 tank. Five clicks on the fire button to power on — Smart Mode activates automatically, reads the coil, sets the wattage on its own. If you'd rather set it yourself: three clicks into the wattage screen, up and down buttons to adjust, three clicks to exit. Prime any new coil before the first fire.
Compatibility
510 thread, 0.15–5Ω. Designed for the GTX coil range but works with anything in that bracket.
GTX Coils that work natively:
- GTX 0.8Ω Mesh — 12–20W
- GTX 1.2Ω Mesh — 7–11W
- GTX 0.4Ω and 0.6Ω also available
Price
The Vaporesso GTX One Mod is available at Vape Online Store for £21.99.
FAQs
- Tank included? No. Mod only.
- What's the point of Smart Mode? Reads the coil resistance when you plug in a tank and sets the wattage automatically. Most useful if you swap tanks regularly. Also just removes one thing to think about.
- GTX One vs GTX One Pro — what's actually different? Pro has a 3000mAh battery (50% more), bigger 0.87" screen, physical lock button, and costs more. Standard GTX One is lighter and smaller. If you do a lot of MTL at lower wattages and want something pocketable, the standard one is fine. If you want more battery and don't mind the extra size and cost, get the Pro.
- My tank uses TFV coils / Smok coils / whatever — will this fire it? If it's 510 thread and the resistance is 0.15 to 5Ω, yes.
- Why does the battery feel small? 2000mAh is enough for a day of MTL vaping at 12–18W. If you're running a sub-ohm tank at 35–40W all day, you'll need a charge mid-day. That's not unique to this mod — it's the physics of battery capacity vs output.
- Is there a lock button? No separate lock button. Five clicks powers the device on and off. For a lock function you'd need the GTX One Pro.
