Vaporesso Gen Nano Kit Review

The Vaporesso Gen Nano Kit is a nano version of the Gen, one of Vaporesso’s best selling mods in 2019. The Nano boasts the newest AXON chip with a 2000mah internal battery, capable of 80 watts of power.

The original Gen has easily been one of my favorite dual 18650 mod. It’s one of the few mods from last year that I continue to use today, and its popularity is evident in the rave reviews it has received by other reviewers and consumers.

However, it’s now time to find out if this Nano version lives up to the same expectations…

At first glance, you might mistake the Gen Nano for the original (besides the size of course!).

It shares the same shape and basic design. When you take a closer look, however, you’ll notice that the button layout has changed, and the USB port now has a new home – on the side of the device.

I would have preferred to have the USB in the same location as it’s bigger brother, but when you downsize a mod to this extent, some sacrifices have to be made, and it’s one I’m okay with.

With it being a nano version, it does come with a 2000mAh internal battery. It’s not enough juice to get me through an entire day, but since it comes with a 2 amp quick charger, it’s something I have been able to easily work with to get me through a full day without being short of power.

Much like the original, the Gen Nano has a very premium almost rubbery feel to it, and you can tell by holding it that it’s a well-built device much like the original, which happens to be one of the things I rated most highly.

You can get the Gen Nano comes in three colors: red, blue, and the ever-popular black. The paint finish looks great and the panels have a nice grippy feel.

The Nano has a similar yet slightly different fire button. They’ve used the same bronze color as they did on the big Gen, but this time it doesn’t have that shiny chrome look. It’s more of a matte. I personally preferred the button look on the original Gen, but it still looks nice to me.

Buttons are a joy to touch and use, with no rattling. The screen isn’t colored, which is not a problem really as long as it is easily readable. And as is it with other Vaporesso products, the branding is subtle and does not detract from the overall design at all.

The tank, which you can swap the glass out for either a 3.5ml or 2ml tube, looks just like any other tank though it fits the Nano well and makes for a pretty combo. You’ll be able to get a 24mm atty on before you see any overhang.

It has a nice, easy top-fill hole and the coils are friction fit rather screwed on.

Overall, the Gen Nano is a beautiful petite mod that I think many of you will grow to love and appreciate.

If I had to nitpick for flaws, it’s that the tank does not sit flush with the mod because the 510 connector has a lip, and the USB port still uses the older micro-USB type rather than the superior USB-C. For me personally, these are not a big deal at all.




When popular mods are scaled down, usually their features are scaled down too, leaving you with a “lite” version, so to speak.

Surprisingly though, the Gen Nano is not your usual scaled down mod – instead it packs features that would put many regular sized mods on the market today to shame.

Functions of the Gen Nano include a Pulse mode where constant voltage is outputted, which helps to give you more consistent flavor.

It also has a Power Eco Mode which helps save you battery when it runs down below 40%.

Temperature control is also done automatically (called Smart TC control) where the mod displays the option to choose the wire you use automatically.

You also get a DIY mode, where you choose the usual settings such as variable wattage, variable voltage, bypass mode, or Super Player Modes (this option will pop up automatically when a super low resistance coil is detected.

One feature I love is Dry Protection. This is where the mod automatically senses when your eliquid is low, helping to eliminate dry hits. Keep in mind, though, that this is only available in Smart TC mode.

Finally, there is Smart VW. This mode lets the device decide which wattage level is best for the coil and resistance you put in. I personally don’t use it, but it’s a feature that could work well for you depending on your vaping style.

To turn the Nano on and off, it’s your usual five clicks with the fire button. Getting into the menu requires three clicks of the mode button, and the up and down navigational buttons are used to scroll through the options.

The mode button will allow you to confirm your selection, and if you need to exit the menu you just press the fire button again.

Clicking the fire button three times will lock the navigation buttons to avoid accidental presses.

In case you are not familiar with the original Vaporesso Gen, the navigation buttons are the two small buttons side by side at the bottom of the device, and the mode button is the lone button below it.

The screen is black and white, but it poses no problems in terms of legibility. It displays the usual pertinent info such as the current power, resistance, battery level, mode, and a puff counter. If you want to flip the screen, you can do this in the settings.

In terms of performance, I have nothing bad to say about the Gen Nano. It performs great, gives accurate readings, and has every function I need and more.




As mentioned earlier, the tank is the GTX Tank 22 is a 22mm diameter with two glass tubes that can house 3.5ml or 2ml. The design is nothing out of the ordinary, but it works as expected.

Though the tank is top fill, it isn’t an easy-to-use “top fill” design per se. Other top fill tanks allow you to either swivel the top cap or twist to remove the top to reveal fill holes, which make things so much easier and less fiddly.

Here, you’ll need to unscrew the top cap completely. You might argue that the miniature size prevents this, but I can’t agree with this. Many other MTL tanks have a feature where you don’t have to screw the top off.

Apart from that, the tank itself is a good performer. It has airflow control, though it only adjusts airflow suitable for direct lung inhalers.

With the tank having such small capacity, if you do vape this device above 40W then you will go through your e-liquid pretty quick (and battery for that matter) so you may want to try and keep around 40W and below.



The Vaporesso Gen Nano Kit will set you back around £35.00 in the UK from VapeSourcing and approximately $50.00 in the US from Vapesourcing too. It is a bit on the high side when compared to other smaller devices, but given the slew of features and build quality, I don’t think you can go far wrong here.




  • Tiny gap between mod and tank
  • Screw-off top fill cap (tank)
  • USB Port on side
  • No USB-C
  • Small tank e-liquid capacity




  • Feature-rich
  • AXON Chip
  • 2A Quick Charging
  • Portable
  • High-quality build
  • Looks and feels nice, sleek and premium
  • Ergonomic
  • Good battery life for a nano device




They say the best things come in small packages, and I think I have to agree in the case of the Gen Nano. The Gen Nano will likely become one of the most popular nano devices on the market.

The tank is decent. Nice that it comes with the kit, but as a heavy vaper I had to swap it with one that has more capacity.

As I’ve reviewed the full kit, I’m going to give it 4 stars, but if this was a review of the MOD on its own, I’d easily bump it up to a 4.5.
