Eleaf iStick Power Nano

Another great starter box mod from Eleaf, the iStick Power Nano, it packs a maximum of 40W power output. It was said to have so much power and features compressed inside a very small mini mod.

Looking closely at the mod, the iStick Power Nano is a smaller version of the original iPower, it only measures 52.5mm by 22mm.The casing was made from heavy duty aluminum; this gives the mod the perfect balance between durability and having a feather-like weight.

The Eleaf iStick Power Nano comes with a temperature control along with a TCR that controls the nickel, titanium and stainless steel output modes.

The iStick Power Nano has an adjustable wattage ranging from 1 – 40W. And also, offers multiple resistance ranges specific for different modes: resistance range of 0.05 – 1.5ohms for TC mode and 0.1 – 3.5ohms for Bypass and Smart Mode.


You can choose between the Bypass and the Smart Mode to suit your vaping style. The Bypass Mode performs like a mechanical mod, giving direct firing without any restrictions. On the other hand, the Smart Mode remembers your wattage setting for different wire resistance. Though I am not a fan of switching modes, this is still a great option for other vapers that seek the perfect configuration for their specific preferences.

There is not much on the top of the iStick Power Nano aside from the 510 Spring loaded contact.

Located at the front, an LED display is available to view the output wattage, ohm reader and the battery indicator. The LED display also shows the menu for the different modes.

The firing button can also be located at the front side of the mod.

And right below the LED display, the control button and the mode button can be found.

Upon navigating the menu, the buttons were inefficient, the buttons were not as responsive as I expected it to be. And the small size feature of the buttons was really an inconvenience.

I tested the mod using the Melo 3 Nano which is included in the package. Using both the 0.75ohm coils and 0.3Coils under the TC mode, mod set at 35W. Setting the wattage near the maximum output still lacks the power to completely heat up the coils, sure it can fire the coils but it is not hitting the right amount of heat. Having said that, the vapor was very limited and the flavor was barely there.

However, testing it using the bypass mode, using the 0.3coil which was designed for direct lung vaping, produced a decent amount of vapor and the flavor. But still, I was not satisfied, I find it lacking in power compared to the other mods in the same category.

The Eleaf iStick Power Nano’s mod has a built in 1100mah battery. When I tested its battery consumption, using the 0.3ohm coils at 35W and vaped for 15minutes, the battery gauge easily went down to around 60%. Extended another 15minutes of vaping, and the battery gauge went down to around 30%. So, that’s just it with the battery, it will not last for 2 hours continuous vaping.

This kit also comes with the Melo 3 Nano. This atomizer measures 22mm in diameter and with a 2ml tank capacity.

The Melo 3 Nano has a preinstalled 0.75ohm coils for MTL vaping. Also, included in the package is the 0.3ohm coils for direct lung vaping.

In the package kit, you will also get spare O-rings and a 510 removable drip tip.

Looking at the physical features of the tank, it is made from Stainless Steel with the 510 threaded contact at the bottom.

It is a top fill tank, easy and mess-free filling can be expected. Simply unscrew the top cap and ppour in the e-juice.

The drip tip is replaceable, which I really like, and is compatible with the usual 510 drip tips in the market.

At the bottom of the Melo 3 Nano, an airflow control can be located. To access the airflow control, simply twist the body of the tank.

As mentioned above, testing the Melo 3 Nano with the iStick Power Nano, did not give me the results I’m seeking to match my preference.

However, when I tested it with my Rx200s at 55W using the 0.3ohm, it performed a lot better. The vapor production was more satisfying and the flavor was even more favorable.


  • The mod is really compact that my palm can almost hide it.
  • Adjustable airflow. The design of the airflow looks really great on the Melo 3 Nano. It is almost hidden giving it the clean plain look.


  • The mode button is really small; guys with bigger fingers will have a hard time pressing that little button.
  • 1100mah will not last for 2 hours.
  • The 0.3ohm coils on Melo 3 Nano is not getting the right amount of power it needs with this mod even at max of 40W.

Eleaf iStick Power Nano kit is a nice sturdy kit. However, having those different modes can be confusing to rookie vapers. It would have been better if they limited the modes by just featuring the bypass mode and smart mode. The 1100mah battery is not enough for a whole day of vaping, unless you use it very seldom within the day. I know that this kit was not designed for the cloud chasers but the performance it gave when using the original kit contents, combination of Melo 3 Nano and iStick Power Nano, was not as good as the other mods in the same category.
