The OLED screen allows you to easily navigate the various output settings and displays the remaining battery power. The iStick Mini also features a micro USB charging port and it takes approximately 1.5 hours to charge using a 1A wall adapter. The iStick features a 510 threading, but also comes with an adaptor for eGo-threaded tanks, allowing you to use virtually any tank on the market.
