The Vaporesso GTX One Pro is a mid-size MTL/RDL vape kit built around a 3,000mAh internal battery, the AXON chipset, and the XTank T top-fill tank, delivering up to 40W of output across four GTX mesh coil resistances (0.4, 0.6, 0.8, and 1.2 ohm).
Powered by COREX heating technology with a Morph-Mesh coil structure and micro-fibre cotton wicking, the GTX One Pro produces consistent flavour from the first puff to the last through Pulse Mode on the AXON chip.
Fitted with a 0.87-inch OLED screen showing seven live functions (mode, puff counter, smart on/off, battery level, wattage, resistance, and lock status), USB-C 5V/2A fast charging, and SSS Leak-Resistant top airflow design, the GTX One Pro is engineered for daily MTL vapers and former disposable users moving to a refillable kit. Fully UK TPD compliant with a 2ml XTank T, MHRA registered, and compatible with any 10ml nicotine salt e-liquid.
Why Choose the Vaporesso GTX One Pro?
3,000mAh Battery with Up to 3 Days Runtime
The 3,000mAh internal battery delivers up to three days of vaping per charge on moderate use, roughly 50% longer runtime than the original GTX One. Actual battery life depends on coil choice and wattage setting.
AXON Chipset with Pulse Mode
Vaporesso's AXON chip controls output across the full 5W to 40W range with Pulse Mode, which keeps wattage stable from the first puff to the last. Includes short-circuit protection, over-discharge protection, and a 10-second cut-off.
COREX Heating Technology
The XTank T uses Vaporesso's COREX heating system with a Morph-Mesh coil structure and micro-fibre cotton wicking. Vaporesso reports a 50% improvement in vapour efficiency compared to standard mesh coils, producing richer flavour at lower wattages.
Four GTX Mesh Coil Options
Compatible with the full GTX mesh coil range in 0.4 ohm (RDL), 0.6 ohm (RDL), 0.8 ohm (MTL/RDL), and 1.2 ohm (tight MTL). The kit ships with the 0.6 ohm pre-installed and a 1.2 ohm spare, covering both main draw styles out of the box.
XTank T with Top-Fill, Top Airflow Design
The included XTank T has a 2ml TPD capacity, top-fill opening via a silicone refill plug, and top airflow adjustment. The SSS Leak-Resistant design minimises leaking through the drip tip and base, even when the kit is carried in a pocket.
0.87-inch OLED Screen
The display is 26% larger than the standard GTX One screen, showing seven live functions at once, mode, puff counter, smart on/off, battery level, wattage, coil resistance, and lock status.
USB-C 5V/2A Fast Charging
Fast-charging via USB-C at 5V/2A charges the 3,000mAh battery in approximately 90 minutes. USB-C cable included in the box.
Premium Build with PU Leather Finish
Aluminium chassis with PU leather side panels, anti-slip silicone base, and precise button feedback. Weighs 140g and measures 137.25 x 23.2 x 30.05mm for a comfortable in-hand feel.
Six Colour Options
Available in Black, Silver, Brown, Red, Pink, and Blue. Each finish pairs the PU leather side panels with a matching chassis colour.

GTX Mesh Coil Options and Recommended Wattage
The XTank T accepts the full GTX mesh coil range. Each coil is tuned for a specific draw style and wattage window. Here's the recommended setup for each resistance.
| Coil | Wattage Range | Best Wattage | Draw Style |
|---|---|---|---|
| GTX 0.4 ohm Mesh | 26W to 32W | 30W | RDL, looser draw |
| GTX 0.6 ohm Mesh (Included) | 20W to 26W | 24W | RDL, balanced |
| GTX 0.8 ohm Mesh | 12W to 16W | 16W | MTL to RDL |
| GTX 1.2 ohm Mesh (Included) | 8W to 12W | 11W | Tight MTL |
The 0.6 ohm coil suits 50/50 VG/PG nic salt e-liquids like DojoLiq, ELFLIQ, and Hayati 10ml bottles at 20W to 26W. The 1.2 ohm coil is best for tight MTL draws similar to a cigarette, paired with 20mg/ml nicotine salt at 8W to 12W.
How to Use the Vaporesso GTX One Pro
First Time Setup
Remove the plastic film, unscrew the XTank T from the mod, open the silicone refill plug on top, and fill with your chosen 10ml nic salt e-liquid. Screw the tank back onto the 510 thread connection. Leave to prime for 5 to 10 minutes so the cotton wicking fully saturates.
Powering On and Off
Press the fire button 5 times rapidly to power on or off. The screen lights up and shows the current coil resistance, wattage, and battery level.
Adjusting Wattage
Press the fire button 3 times to open the menu. Use the + and - buttons to adjust wattage within the recommended range for your coil, 8W to 12W on the 1.2 ohm coil, 20W to 26W on the 0.6 ohm coil.
Locking the Device
Hold the + and - buttons together for 3 seconds to lock the fire button and prevent accidental firing in a pocket. The lock icon appears on the OLED screen.
Changing the Coil
Unscrew the XTank T from the mod, empty any remaining e-liquid, unscrew the base, and pull out the old coil. Insert the new coil, screw the base back on, refill with e-liquid, and prime for 5 to 10 minutes before vaping to prevent dry hits.
When to Replace Your GTX Coil
GTX mesh coils typically last 1 to 2 weeks with regular daily use, depending on the e-liquid, wattage setting, and vaping frequency. Replace the coil when you notice any of the following signs.
- Burnt or harsh taste on every draw, even after refilling with fresh e-liquid
- Reduced flavour intensity compared to a fresh coil
- Noticeably thinner vapour production
- Gurgling sound when inhaling, caused by flooded or worn wicking
- Leaking from the tank base or airflow holes
- Darkened e-liquid colour in the tank window
Sweet dessert and custard e-liquids shorten coil life compared to fruit or menthol flavours. Replacement GTX mesh coils are sold in 5-coil packs at OrderVape.
Who Is the Vaporesso GTX One Pro Best For?
Vapers Moving from Disposables
The 1.2 ohm coil at 10W to 12W delivers a tight MTL draw similar to the cigarette-style draw of former disposable vapes, making the GTX One Pro a solid step up for vapers switching to a legal rechargeable kit post-June 2025 UK ban.
Daily MTL/RDL Vapers
The 0.6 ohm coil at 20W to 26W delivers a balanced restricted direct lung draw with strong flavour reproduction, suited to daily vapers who want more vapour than a pod kit without going full sub-ohm.
Vapers Who Prefer Coil Swaps Over Pod Changes
Unlike pod kits like the XROS 5, the GTX One Pro lets you change just the coil (not the whole pod), making running costs lower and letting you reuse the same XTank T for months. One coil pack of 5 covers 5 to 10 weeks of vaping.
Vapers Who Want Multi-Day Battery Life
The 3,000mAh battery lasts up to three days per charge on moderate daily use, significantly longer than the 1,500mAh batteries in the XROS 5 and Luxe X Pro.
Vaporesso GTX One Pro vs XROS Pro 2
Both the GTX One Pro and the XROS Pro are mid-tier MTL/RDL Vaporesso kits, but they differ significantly in format and running cost. Here's the direct comparison.
| Feature | GTX One Pro | XROS Pro 2 |
|---|---|---|
| Format | Mod + XTank T (coil swap) | Pod kit (pod swap) |
| Battery | 3,000mAh | 2,000mAh |
| Max Wattage | 40W | 30W |
| Tank / Pod | XTank T, 2ml | COREX 3.0 pod, 2ml |
| Consumables | GTX mesh coils (5-pack) | COREX 3.0 pods (2-pack) |
| Draw Styles | MTL and RDL | MTL and RDL |
| Screen | 0.87-inch OLED | 0.96-inch colour screen |
| Best For | Lower running cost, bigger battery | Compact daily carry |
The GTX One Pro wins on battery life, wattage headroom, and lower long-term running cost. The XROS Pro 2 wins on pocket size and simpler pod-swap operation.

Frequently Asked Questions
Is the Vaporesso GTX One Pro MTL or DTL?
The GTX One Pro supports MTL (mouth-to-lung) and RDL (restricted direct lung) draws, not full DTL. The 1.2 ohm coil at 8W to 12W gives a tight MTL draw similar to a cigarette, while the 0.6 ohm coil at 20W to 26W gives a looser RDL draw. For sub-ohm DTL cloud chasing, see the Vaporesso Armour Ultra instead.
What coils does the Vaporesso GTX One Pro use?
The GTX One Pro is compatible with the full GTX mesh coil range, 0.4 ohm (26-32W, RDL), 0.6 ohm (20-26W, RDL), 0.8 ohm (12-16W, MTL/RDL), and 1.2 ohm (8-12W, tight MTL). The kit ships with the 0.6 ohm pre-installed and a 1.2 ohm spare. All four resistances are sold as 5-coil replacement packs.
How long does the GTX One Pro battery last?
Vaporesso's own testing reports up to 3 days of vaping per charge on moderate use, 50% longer than the original GTX One. Actual runtime depends on coil resistance and wattage, lower-wattage MTL setups (1.2 ohm at 10W) will exceed 3 days, while 0.4 ohm at 30W will drain the 3,000mAh battery faster.
How do I fill the XTank T?
Open the silicone refill plug on top of the XTank T, insert your e-liquid bottle nozzle, and fill up to the 2ml maximum line. Close the plug firmly, let the tank sit for 5 to 10 minutes to prime the cotton wicking, then vape as normal. Top-fill design means you don't need to remove the tank from the mod.
What e-liquid should I use with the GTX One Pro?
For the 1.2 ohm coil, use 50/50 VG/PG nicotine salt e-liquid at 10mg or 20mg strength, such as DojoLiq, ELFLIQ, Hayati, or Riot Salts. For the 0.6 ohm coil at higher wattages, you can use 50/50 nic salts at 10mg strength or standard 50/50 freebase e-liquid.
What is COREX heating technology?
COREX is Vaporesso's proprietary heating system used in the XTank T, combining a Morph-Mesh coil structure with micro-fibre cotton wicking. Vaporesso's lab testing reports a 50% improvement in vapour efficiency compared to standard mesh coils, meaning richer flavour at lower wattages and longer coil life.
How often should I change the GTX coil?
GTX mesh coils typically last 1 to 2 weeks with regular daily use. Replace the coil when you notice burnt taste, reduced flavour, thinner vapour, or gurgling on inhale. Sweet and custard e-liquids shorten coil life compared to fruit or menthol flavours.
Is the Vaporesso GTX One Pro UK TPD compliant?
Yes. The UK version of the GTX One Pro ships with a 2ml XTank T (TPD maximum), is MHRA registered, CE certified, and fully compliant with the UK's post-June 2025 regulations on refillable vape kits.
Does the GTX One Pro leak?
The XTank T uses Vaporesso's SSS Leak-Resistant design with top-fill and top airflow, significantly reducing leaking compared to bottom-airflow tanks. To prevent leaks, always prime new coils for 5 to 10 minutes, don't overfill past the 2ml line, keep the airflow fully open during use, and replace worn O-rings if you notice seepage.
What's the max wattage on the GTX One Pro?
Maximum output is 40W, with an operating range of 5W to 40W. Actual recommended wattage depends on the coil, 8-12W for the 1.2 ohm, 12-16W for the 0.8 ohm, 20-26W for the 0.6 ohm, and 26-32W for the 0.4 ohm.
How do I spot a fake Vaporesso GTX One Pro?
Every genuine Vaporesso pack includes a scratch-to-reveal security code on the outer box that scans against Vaporesso's official authentication page. Genuine units have precise button clicks, the AXON chipset's distinctive LED feedback on startup, and holographic authenticity stickers. Buy only through authorised UK retailers like OrderVape.
Can I use the GTX One Pro with any tank?
The GTX One Pro has a 510 thread connection and can technically run any 510-threaded tank, but it's optimised for the XTank T at 5W to 40W. Using high-wattage sub-ohm tanks beyond 40W is not supported, and larger tank bases over 24mm may overhang the mod.
