The iStick Pico by Eleaf is a tried and true single battery device.

Due to the mechanism used to secure the battery hatch, the Pico is only capable of using 22mm and smaller atomizers. The device is capable of outputting 75watts and has full temperature control compatibility.

The Pico has withstood the test of time, and we regularly see these devices take on heck of a beating and keep on trucking.

The single replaceable 18650 that this device uses is secured with a threaded cap. This means that you’ll never have to worry about your battery flying out of your device if you drop it.
