Vaporesso GTX GO 40 and 80 Starter Kit Review (2026)

Updated 2026-07-21 — Originally published 2021-07-01

Vaporesso has been a trusted name in vaping gear for years. This pair of vape pens proves the brand still knows how to build a solid, no-nonsense device. The vape pen format never really went away — it just got quieter while pod systems and mesh coils stole the spotlight. Vaporesso brought it back with a refresh in 2026, and the vaporesso gtx go 40 sits right at the center of that comeback alongside its bigger sibling, the GTX GO 80.

So does it still hold up? We spent real time with both pens to find out.

Key Takeaways

• The Vaporesso GTX GO 40 is compact, beginner-friendly, and pairs well with 0.4-ohm and higher coils.
• The GTX GO 80 offers more power, a bigger battery, and noticeably better airflow for flavor chasers.
• Both use Type-C charging and GTX mesh coils, with magnetic pods that make refills simple.
• US tank capacity sits at 3.5ml (GTX GO 40) and 5ml (GTX GO 80) — no 2ml restriction like UK models.
• Street prices in 2026 typically run $25-$35, making this one of the more affordable vape pen kits still worth buying.

Design

Vaporesso stuck with the classic vape pen shape here, and honestly, that’s the right call. Both the GTX GO 40 and GTX GO 80 use a metal-and-rubber shell that grips well in the hand and doesn’t feel cheap. Just one button sits on each device — simple by design — with a light ring around it that shows battery status at a glance.

The pod (Vaporesso still calls it that, not a tank) snaps onto the base with magnets. Pull to remove the coil; rubber washers keep leaks in check. Filling is easy too. Unscrew the top cap and you’re staring straight at the fill ports — no fiddly bottom-fill nonsense.

Size-wise, the vaporesso gtx go 40 is impressively small for how much power it puts out. “40” refers to its max wattage. It measures 110.3mm tall with a 22mm diameter and holds 3.5ml of e-liquid in the US version.

Built to house a larger battery, the GTX GO 80 is the bigger of the two. It measures 133.2mm long with a 26mm diameter and a 5ml tank. Both kits ship with US-spec tank capacities. No need to worry about the reduced 2ml sizes required under UK regulations.

Features

Don’t let the simple one-button layout fool you — there’s more going on under the hood than you’d think. The main thing is auto wattage control: pop in a coil, and the device reads it and adjusts power automatically. New vapers don’t have to touch a single setting to get a clean vape. A stack of standard safety cutoffs (short-circuit, overheat, that kind of thing) also shuts the device down before anything goes wrong.

On the power side, the GTX GO 40 runs a 1500mAh battery and charges via USB Type-C — a nice touch that’s now standard across most decent vape pens. The GTX GO 80 doubles that with a 3000mAh cell, also charged over Type-C.

Airflow adjusts by twisting the pod itself. No buttons, no menus. Turning either device on takes five clicks of the fire button, the same gesture nearly every manual vape uses these days. Once it’s on, the light ring tells you where your battery sits: green for 70-100%, blue for 30-70%, and red under 30%.

None of this reinvents the category. But it’s exactly what you want in a pen-style vape — beginner-friendly without being dumbed down.

Performance

Vaporesso GTX GO 40 Performance

The GTX GO 40 ships with a GTX 0.6ohm mesh coil. Quick tip: wet the coil with e-liquid before your first pull, or you’ll scorch the cotton and ruin it on day one. That’s not unique to Vaporesso — it’s true of pretty much any mesh coil on the market.

Airflow is the only thing you can really tweak here, since wattage adjusts on its own. With the airflow wide open, the flavor came through cleanly — not mind-blowing, but solid. We ran this pen for two straight days of regular use before forming an opinion, and it held up well.

Our take: it’s a genuinely well-built pen for its size. There’s a touch of draw resistance thanks to the 0.6-ohm coil (higher-ohm coils tend to have a tighter airflow channel), and the power felt slightly restrained compared to what we’re used to running on box mods. That’s more about our own vaping habits than a flaw in the device. We only noticed these quirks after testing the GO 80. On its own, the GO 40 is a genuinely satisfying vape.

Vaporesso GTX GO 80 Performance

The GTX GO 80 comes with a GTX 0.2ohm mesh coil, and the difference shows immediately — more airflow, more power, more flavor. We tested this one for what was supposed to be two days and ended up carrying it around a lot longer than that, which says something.

The 0.2-ohm coil makes everything feel punchier. More air moves through, which pulls more flavor off the coil. That’s not really a knock against the GO 40 — it just means the GO 80 is tuned for people who want a bigger, airier draw.

In our opinion, the GTX GO 80 edges out the 40 slightly on overall satisfaction, but the gap is small. You’d only really notice it after switching between the two over several sessions.

Difference Between the GTX GO 40 and the GO 80

Here’s the short version. Grab the GO 80 if you’re used to box mods or higher-wattage devices and want something smaller to carry around. The vaporesso gtx go 40 fits better if you’re newer to vaping, or you tend to vape 0.4-ohm coils and above — and it’s noticeably smaller in your pocket.

Final Verdict

We came away impressed with the Vaporesso GTX GO 80. It’s a small, well-made device that delivers a genuinely flavorful vape, with airflow control that’s simple to use and actually effective. The vaporesso gtx go 40 isn’t far behind. It just comes up a little short on raw power. Swapping in a different coil (sold separately) could close that gap, though we didn’t test alternate coils ourselves.

Vaporesso has built a strong reputation over the years, and the GTX GO lineup shows the brand still knows how to make a vape pen worth buying in 2026. If you’re shopping around, it’s also worth comparing this kit against other best beginner vape kits currently on the market, or checking current deals before you commit to a price.

Frequently Asked Questions

How do you change the power on a Vaporesso GTX GO 40?

You don’t manually set the wattage on the GTX GO 40 — it reads the coil’s resistance and applies the correct preset wattage automatically. The only adjustment you control directly is airflow, which you change by twisting the pod section on the base of the device.

How long do Vaporesso GTX coils last?

Most GTX mesh coils last somewhere between one and two weeks with regular daily use, though this varies a lot based on how often you vape and what e-liquid you run. Sweeter, higher-VG juices tend to gunk up coils faster than simpler nic salt blends, so heavy users of dessert flavors may need to swap coils more often.

Why is my Vaporesso GTX GO 40 leaking?

Leaking usually comes down to a loose top cap, a damaged rubber seal on the coil, or overfilling past the max fill line. Check that the coil is fully seated and the washers aren’t torn, and make sure you’re not tilting the pen sideways for long periods right after filling, since that gives e-liquid time to seep past the airflow slots.

How many watts is the GTX GO 40?

The GTX GO 40 tops out at 40 watts, which is where its name comes from. It has a usable range starting around 5W, with the device automatically selecting the right wattage based on the coil you install.
