Review Summary


The Nano 510 battery gives a powerful experience despite its minuscule size. It has variable voltage and a preheating function, giving users more control over the flavor. It also has a large battery capacity for it’s size and an auto-off feature. If you’re looking for the smallest battery around, you’ve just found it.

Design and Features


The Nano stays true to its name with its compact size. It literally fits right into anyone’s hand, making it extremely discreet to use. This also means that you can easily put it into your pocket without it feeling too bulky.

Variable Voltage

The great thing about variable voltage is that it gives you better control over the flavor and how smooth each hit would be. In the case of the Nano, you can set it to 3.4, 3.7, or 4.0 volts, allowing you to adjust to different cartridges, oils, and other elements that may affect your overall experience.

Normally, 3.4 volts works best for plastic cartridges while 3.7 is a great match if you use ceramic or glass cartridges. 4.0 is also a good fit for ceramics.

Large Battery Capacity

Despite its size, the Nano has a large 650mAh battery capacity. This gives you enough vaping power that lasts a good couple of days in between charges.


The Nano automatically turns off after 10 seconds of inactivity. This saves you from potentially discharging your battery or accidentally using up your oil in your pocket or in your bag. 

Pre-Heat Function

Not everyone likes pre-heating their oil, but the pre-heat function on the Nano could be a bit useful especially if you’re using it in colder climates where your oil could get too cold for comfort. Just remember that exposing the oil to too much heat would change its flavor, so don’t overuse this function as well.

Cartridge Compatibility

Compatibility-wise, the Nano allows you to use any of your favorite 510 thread carts, and could even accommodate some carts with a bit larger diameters.

Bottom Line

Don’t underestimate the Nano because of its size. Despite being one of the smallest out there, it still lets you have some big hits. Its flexibility in terms of compatible carts and voltage options makes it a great fit for different preferences. 

Some might feel that $40 is too much for such a small device, but its performance is impressive enough for me to say that it’s totally worth the price. Add to that the lifetime warranty that comes with it and you have quite a package that gives you great value for your money.
