The Gen Nano is a shrunken down, lower power version of the Vaporesso Gen. The Vaporesso Gen 220W was one of the most popular box mods of last year and it remains popular to this day. The Gen Nano retains the same design, modes, and features that made the Gen such a hit, but it does so in a smaller, more pocketable form factor.

The Gen Nano has a maximum wattage output of 80W and uses a 2000mAh built-in battery. It uses the same AXON chip as the Vaporesso Gen and brings Pulse Mode, three wattage modes, TC modes, and more.

The kit comes with the GTX Tank 22; a 22m tank with a 3.5ml eliquid capacity. This tank uses the same GTX coils as the Target PM30, PM80, and PM80 SE.

As the saying goes: big things come in small packages. I’m going to find out if this rings true for the Gen Nano kit.

This kit was sent to me by Vaporesso for the purpose of this review.

Design & Build Quality: Gen Nano Mod

  • Vaporesso Gen Nano Mod 3

The Gen Nano is literally like a shrunken down Gen. I, like many others, loved the look and feel of the original so it’s great that they kept everything more or less the same. 

The Gen Nano has the same soft touch, semi-rubberized coating and dimpled panels, and the same bronze accents for the logos and fire button. The semi-rubberized coating feels great and the paintwork looks good, too. I didn’t love the bronze accents on the original Gen but to be honest, it has sort of grown on me.

The shape is identical to the original; rounded edges and curved front and back panels that sit perfectly in my palm. Appearance wise the only major change from the Gen is that the Gen Nano is much, much smaller. It’s only 70mm tall, 40.3mm wide, and 24.2mm thick which is the same size and width as some pod vapes! For reference, the Gen 220W is 93.5mm tall, 53mm wide and 27mm thick. 

For a box mod with a 2000mAh built-in battery, it’s surprisingly light. Even with a tank attached, it’s lighter than some pod vapes. The small size and lightweight make  the Gen Nano perfect to slip into a pocket; the shape slides into my jeans pocket easily and I barely even notice that it’s there.

There are six colors available. Two of them are solid colors, black and silver. The other four have a gradient finish that fades to black at the bottom of the device. This gradient looks really neat and it makes an already good looking mod look even more attractive.

The 510 is gold plated and spring loaded. It’s centered and will take up to 24mm tanks without overhang. 22mm tanks like the GTX Tank 22 that comes in the kit look right at home. 24mm tanks don’t look out of place either but they’ll sit just flush with the edges of the mod.

The screen on the Gen Nano is the same 0.91” OLED. It’s bright and displays your battery charge in percentage, coil resistance, puff time, wattage, and mode. Another useful feature is that it displays a suggested wattage range based on the coil that you’re using. This is perfect for those times when you forget what the suggested wattage range of your coil is and saves you from having to look it up.

The buttons are all well-made and responsive. They work with just the right amount of pressure and there’s no button rattle at all. The overall build quality of the Gen Nano is similar — well-made and precisely built. I can’t find anything to complain about here. 

Features & FunctionsVaporesso Gen Nano Features

The Gen Nano is a small mod but it still packs all of the same features as it’s full-sized big brother. It will fire at up to 80W in wattage mode and from 200-600°F in TC mode.

There are three wattage modes: soft, normal, and hard. There’s also variable voltage mode, custom wattage curve mode, and bypass mode.

For temperature control vaping there is your normal SS, TI, and NI modes. You can change the TCR value for each mode as well as set your wattage. In addition to these three TC modes, there’s also a manual mode where you can input your TCR value and wattage. 

In addition to these more common and expected modes, there are four additional “special” modes. Pulse mode is the default mode on the Gen Nano. It works similar to regular wattage mode except it pulses the wattage every 0.02S. This pulsing isn’t noticeable when you’re taking a draw but I feel like it does make a difference to the flavor and temperature of the vapor. Compared to regular wattage mode vaping, longer draws feel smoother and the vapor doesn’t feel as hot.

Power Eco is a mode that helps to preserve battery life. The Gen Nano will ask you if you want to change the mode to Power Eco when you get to around 40% battery. You can also make Power Eco mode turn on automatically by turning on “Auto Eco” in the settings menu.

Smart TC mode automatically detects your coil materials and sets the correct TC mode for that material. I found this to be hit or miss and sometimes the Gen Nano didn’t correctly identify my coil. If this happens you can still set the TC mode manually, so this isn’t too big of a deal.

Super Player mode allows you to vape on super low builds that wouldn’t normally fire on other mods.

Gen Nano Button Combinations

  • Turn the Gen Nano On/Off: Five clicks on the fire button. 
  • Lock the adjustment/menu buttons: Three clicks on the fire button.
  • Enter the Menu: Three clicks on the middle adjustment button.

NOTE: DIY menu is where you’ll find the “regular” modes (Variable Wattage, TC, Bypass)

GTX Tank 22

  • GTX Tank 22

The GTX Tank 22 is included with the Gen Nano Kit. It’s a small 22mm tank that comes in the same color as the Gen Nano. The top cap and airflow control ring have knurling for grip and it goes really well with the aesthetics of the Gen Nano.

The top cap is threaded and unscrews. Removing the top cap exposes the inside of the tank so it can be filled anywhere inside the glass. No matter what the size or type of bottle, there’s no trouble filling up.

A 3.5ml bubble glass comes preinstalled on the GTX Tank 22. It also comes with a 2ml straight glass in the box. Compared to other sub ohm tanks, 3.5ml is small but it’s manageable with the 0.6ohm coil. If using a lower resistance coil, be prepared to fill up often.

What I particularly like about the GTX Tank 22 is that it’s compatible with all GTX coils, which are the same coils used by the PM30, PM80, and PM80 SE. The fact that all of these devices use the same coils gives me hope that these coils are going to be around for a while. And because so many devices use these same coils, they should be easy to find online or at local vape shops far into the future. Plus, there’s also an RBA coil available if you  want to build your own coils.

The GTX Tank 22 comes with two coils: 

  • a 0.2ohm mesh coil (Rated for 45-60W)
  • a 0.6ohm mesh coil (Rated for 20-30W)

The 0.2ohm coil is the same coil that comes with the PM80 and PM80 SE. The 0.6ohm coil is the same coil that comes with the PM80 SE and PM30. If you have coils for any of these devices then you’ll be able to use them in this tank. These coils push into the bottom of the tank so installation or removal is simple.

There are three airflow slots on the base of the GTX Tank 22. These slots are pretty small so the draw that you get from this tank differs quite a bit from the draw that you get with the PM series devices. I’ll elaborate more on the airflow in the next section. This airflow control ring is fully adjustable and works on a stopper. It can be fully closed if needed.


  • Vaporesso Gen Nano Kit 1

Due to the small airflow slots on the tank, the draw from these coils are quite a bit different than what you get from the PM series pod mods. Whereas the PM series of mods gives a more open draw with these coils, the GTX Tank 22 delivers more restriction.

The 0.2ohm coil is good as ever in this tank. It’s rated from 45-60W and that’s an accurate rating. This coil can handle high VG ejuices without a problem and can even take being pushed a little past its rating. 60W is a perfectly warm vape with really good flavor and huge clouds. 65W is just slightly better but it’s a little too warm for my taste. The draw is quite airy and open, so I prefer to vape this coil with the airflow a third of the way closed.

Restricted lung hits are where it’s at with the 0.6ohm coil. The flavor from this coil is good. The clouds are actually respectable too for what it is. This coil is rated for 20-30W, but it vapes best on the lower end of this rating. The sweet spot with this coil is 22.5W, and this is especially true when using a high VG ejuice. 80VG gave me trouble anywhere higher than 25W, but vaped perfectly fine at 25W and under.

The Gen Nano fires pretty much instantly when I hit the fire button. There’s no lag at all, just instant vapor. Similar to the original Gen, the Gen Nano has a pretty good temperature control mode. It throttles at the right times and doesn’t get too aggressive. The vapor at 410°F feels like it should at 410; warm but not too hot. For a mini TC mod, the Gen Nano does it really well.

I had no performance or leaking issues while using this tank. Same goes for the Gen Nano mod. They both worked perfectly fine and I vaped without any problems.

Battery LifeVaporesso Gen Nano Mod 4

The Gen Nano has a 2000mAh battery and charges using Micro-USB. Although it’s not Type-C charging, it still charges pretty quickly thanks to 2A charging capabilities. Usage times will vary depending on what coil you use, but from my testing the battery life is stellar.

I vaped close to 400 puffs with the 0.6ohm coil at 22.5W. This is over a few days of use which is pretty incredible. Talk about long lasting!

Using the 0.2ohm coil at 60W gave me more moderate results. I vaped close to 150 puffs on a single charge which still isn’t bad for such a small mod.

With the 2A charging rate, the Gen Nano fully charges in only an hour. The screen displays how long it will take until a full charge, so that’s pretty useful and cool as well.


The Gen Nano is a really impressive mini-mod. It’s just as nice and full-featured as the full-sized Gen, but has the advantages of being more pocketable and lightweight. 

The GTX Tank 22 and coils that come with the Gen Nano Kit give anywhere from an open DL draw with the 0.2ohm coil to a restricted lung hit with the 0.6ohm coil. These coils will satisfy any DL vaper. In addition to the included coils, you can also get any of the other GTX coils or the RBA coil if building is your thing.

Impeccable build quality, amazing performance, and a host of modes are all reasons to get the Gen Nano. The wide range of coil choices for the GTX Tank 22 makes the kit worth picking up, too.

Overall, a solid kit. It’s worth picking up.

  • You forgot that it is LITERALLY impossible to get a replacement glass for the original 3.5ml. Trust me I’ve wasted $30 over the past 2 months. What does it say about vaporesso that they dont sell replacement glass for their own products
