The battery is rated at 1050 mAh which for a box mod may not seem a lot but considering the device measures just over 2 inches in length the capacity seems ample. The build itself is excellent, the iStick Mini feels solid in the hand, fitting perfectly into the palm and while the buttons do rattle a bit it’s not an issue (at least for me). The threading is 510 compatible but there is an included EGO adapter that works perfectly.

The voltage range goes from 3.3v-5v in 0.1 increments so for my personal use this suits just fine. Voltage selection is made with two arrow buttons, up and down, no round robin voltage selection here. There is also the standard on/off function activated by pressing the power button 5 times in quick succession.     

One of the other things I like about this e cig is the simple digital display on the top of unit. This is a round display that does just two things. The first is showing how long, in seconds, you press the power button for on each draw. The second is showing a percentage of the remaining battery life. The first function isn’t that useful for me but the second does come in handy doing away with the guess work on how much power you have left.
