Customer Review

The external battery is 7800 mAh RAVPower compact (6x9x1 cm) and lightweight (less than 180 grams). Supplied with a USB cable, it will charge in less than 4 hours and then provides impressive reserves, able to charge several devices (iSmart technology to optimize load times). The battery has a power button (on / off) and a blue LED line (4 levels), to display its charge level.

Among the batteries tested until today, the external battery 7800 mAh RAVPower is now the one that best fits my user needs "average" looking for lightweight and simple and practical character of this model more sophisticated batteries (taken for many more simultaneous loads, but greater weight and size).
