>>NEVER BE STRANDED WITH 0% CHARGE ON YOUR PHONE AGAIN.

This is a seriously small portable phone charger and it was primarily designed for emergency use with NO effect on your phone.

It is small enough to carry it around wherever you go and doesn't depend on you remembering to charge it, and it relies on something readily available everywhere: household AA BATTERIES. 

It is fairly SAFE as well as SMART as it's NOT going to overheat or overcharge your device, once the power reaches full, it automatically shuts off and prevents overcharging.

Bring that extra battery boost to your smartphone, with just a pair of household AA batteries.
