We have covered plenty of cool battery packs for smartphones in the past. Not too many of them integrate with your iPhone charger though. The STROM happens to be an interesting charger that works with your Apple Wall charger, charging your iPhone and itself at the same time.
STROM works with iPhone, Android, and other smart devices. It comes with KEYBLE charging cable, allowing you to recharge your phone anywhere. STROM has a 3400 mAh battery inside. Like what you see? You can find it on Indiegogo.
