It’s been a minute since we reviewed a true beginner’s vape device — read: “not a pod mod.” Simple, but not dumb. Powerful, but not unwieldy. Compact, without being too limited. The Vaporesso GTX One kit is designed as an entry-level mouth-to-lung (MTL) setup, but to label it this way seems almost unfair. This is a good intro to advanced vaping, and one of the brighter surprises of 2020 so far.

Vaporesso GTX One

Discover the Vaporesso GTX One 40W Starter Kit, featuring a 2000mAh battery, 5-40W range, and comes with the ideal GTX 18 Tank to deliver MTL or DTL vapor. Constructed from durable zinc-alloy, the GTX One Starter Kit maintains an integrated 2000mAh battery rechargeable via Type-C MicroUSB Port. With a range between 5-40W, the GTX One can deliver vapor in MTL or DTL fashion thanks to its pairing with the GTX 18 Tank that is compatible with the extensive GTX Coil Series. Within the bubble glass tank the GTX 18 Tank can accommodate fills of up to 3mL through its top fill system while allowing coil changes from the bottom in a press-fit manner.

Aesthetics of the Vaporesso GTX One

The GTX One mod is an ideal size for beginning vapers. At 127.5mm tall (without tank), the mod is slender but tall enough to feel like an adult device, not a diminutive toy. With a 2,000mAh internal battery and zinc alloy construction, the GTX One has enough heft to feel commanding, but not overly heavy.

Vaporesso GTX OneAnd the device design is sharp enough to stand out, without drawing attention. It’s an attractive mod that strikes all the right notes. (Yes, even on my pink test model.)

The 0.69-inch OLED screen does what it needs to do – providing all the necessary information, without any visual trappings to get in the way. Get in, get vaping, move on with your day. It ain’t pretty, even by older standards, but it does the job.

The press-fit 510 connection is standard fare, but seemed more than sturdy enough, and all my test tanks sat flush without concern. Finally, the large firing key feels extremely solid, and works equally well in a trigger or thumb grip style.

Yes, the Vaporesso GTX One seems pretty “bare bones.” But that is clearly by design.

The Vaporesso GTX 18 Tank


The included GTX 18 tank was an appropriate inclusion, and a high-performing one at that. Despite the advertising talk, this tank is designed strictly for mouth-to-lung use, preferably with lighter (but not nic salt) e-liquids, this tank makes no attempts to be a multipurpose, versatile device. In other words, keep those VG-heavy e-liquids away from here, it’s simply not going to work out for you.

However, with thinner, PG-heavy juices, the easy-to-fill tank shines. It took a little while for me to “remember” how to vape MTL-style, but once I re-acclimated to the snug airflow and restricted draw, I found the GTX 18 was a solid, flavorful atomizer, with surprisingly ample vapor for a MTL setup.

The 0.8 and 1.2 ohm coils in the box both lasted well over a week each, with solid performance till the bitter end. And even then, the experience was still good, but flavor began to mute, while vapor production diminished considerably.

But the coils, despite the narrow juice ports, never once offered a dry hit or burnt flavor, even when pushing past the listed maximum. Strong performers in that regard.

Vaping the Vaporesso GTX One Kit

As mentioned above, the included GTX 18 tank offered the best experience when paired with its companion mod. Right out of the box, this married pairing provided a seamless, simple vape that rarely went past 20 watts, yet offered more than enough power and vapor to keep most vapers at bay.

But I was intrigued by the 40-watt potential of the GTX One, so I decided to slap on an older, smaller tank and a fresh coil to see how deep into sub-ohm waters we could go. It turns out, the GTX One has SOME chops at higher elevations … but your battery life might make you stick to MTL use.

At a more-reasonable 25 watts, I started puffing, using a 0.5-ohm coil. Naturally the vapor was a little weak at this level, so I pushed up a little more, and found that it offered a nice balance of flavor and vapor. I wasn’t pushing the coil past its limits, but it was satisfying.

40W Limit Test

If only it lasted. The 2,000mAh internal battery certainly offered strong draws, but the max wattage began taking its toll on battery life soon after. Before long, I was getting low power warnings WAY earlier than expected, forcing me to recharge soon after.

At just 20-30 watts, the GTX One offered near-all-day longevity. For the occasional sub-ohm tinkering, the GTX One is more than capable – especially given the smooth, steady power it provided. But this mod was not meant for these purposes, and it showed.


  • Slender, pocketable format
  • Strong MTL performance
  • Long-lasting coils


  • Battery life fades over 30 watts
  • Antiquated design
  • Tank isn’t very versatile

Bottom Line

GTX One TankThe Vaporesso GTX One is one of the best dedicated beginner MTL devices I’ve tested to date. The fact that I had to push the mod into sub-ohm territory to find flaws is pretty indicative of how solid this device is. It’s more attractive than a stick mod, more customizable than an AIO device, and a much better bridge between entry-level and advanced vaping.

When used as intended (especially with the included GTX 18 tank), the Vaporesso GTX One will offer bold flavor and satisfying vapor in a very competitive package. Yes, the battery life suffers at higher wattages, but as an MTL device, this shouldn’t be a concern.

If there’s a new vaper on your shopping list, strongly consider the GTX One kit when browsing online.
