The Mini iStick variable voltage battery is small yet powerful at 10 Watt 1050mAh . 510 thread fits all tanks but especially well suited to the eLeaf GS-16S, the Kangertech eMow and the Mini Nautilus by Aspire.
Features a uniquely positioned crystal display on the top of the unit which measures vaping time of each puff and shows the remaining charge in percentage immediatly after the button is released. Comes in 4 beautiful colours and can be used while charging with no need to detach the tank. The unit also charges really fast, less than an hour I have found.
