Despite its small size, the iStick is loaded with amazing features. Voltage is adjustable from 3 volts to 5.5 volts while wattage ranges from as low as 2 watts to as high as 20 watts.
The OLED screen, the up and down buttons, and the fire button are all aligned on one side of the device so it is very easy to tweak your settings. You have full control over your iStick with just a few flicks of your fingertips. The super bright OLED screen is easy to read and displays all the necessary info such as wattage, voltage, atomizer resistance, and battery level.

Unlike many box mods that offer adjustment only in 0.1 volt and 0.5 watt levels, you can customize your iStick to change settings in 0.2V/0.2W or 0.5V/0.5W increments so you don't have to press the button so many times in order to achieve your desired hit.
The eLeaf iStick runs on a powerful 2200 mAh battery that allows you to vape all day without recharging. Even when power is low and it's time to charge, you can still use your iStick via the passthrough function. To make sure that your iStick is always ready to fire, we recommend that you purchase a USB car adapter so you can enjoy continuous vaping while on the road.
For your peace of mind, the iStick is packed with safety features such as 10-second automatic shutoff protection, short circuit protection, low voltage protection, and low power alert.
Although the iStick is designed with native 510 connection, there is a adapter available to purchase separately so you can use virtually any type of atomizer, clearomizer, and glassomizer on the market.
The eLeaf iStick comes in four basic colors – black, blue, silver and pink. For best results, use the iStick with an Aspire Nautilus Mini.
Tip: When holding the button up or down, settings will adjust by 0.1. Press the button again to move 0.2 increments and one more time to increase or reduce by 0.5.

I started vaping 13 years ago to quit smoking. I started out with the Eleaf istick mini. I have tried the Voopoo, Aegis Geek Vape. I guess I'm old school because I always come back to Eleaf istick. I'm 74 and the bigger mods were too much for me. I just ordered another Istick mod.

My 510 thread Geekvape Z Nano 2 tanks won't fire with this E-Leaf stick. After pressing the fire button, the window says "Atomizer low". The instruction manual print is so small it's unreadable even with a magnifying glass. What are my options?

Works great. The 40w was out of stock but this works fine

I had and used an Innokin Coolfire IV for THC carts for a solid 8+ years. The battery finally overheated and I needed a replacement mod. The iStick feels almost as equally robust and is also a little more compact and lighter. Great for THC carts.

I have previously been happy with I stick 20 but some problems recently have me concerned. I recently purchased 3 aspire nautilus 3 tanks from another company since you were out of stock. One of them does not work with either eleaf 20 that I purchased about a month ago, although the two others work fine. That tank works fine with an older I stick. I’m not sure whether the tank or new eleaf istick 20 is responsible.
