Genius BB Tank-Key Fob Mod
The Genius kit 350mAh Key Box Battery is a discreet, transportable battery unit. The most apparent aspect of this battery is the fact that is it designed to look like a laser-cut key component that is carried on a key chain. A single button releases the attachment port. That piece has a 510 thread attachment which is very common threading among industry tanks or cartridges. Both of which are not included in the package. It is able to output 3.7V of power, the Genius kit creates an amazing vaping session.
