Customer Review

At the effigy of Ravepower this external battery has a really pretty neat and sleek design, with its black hull and 4 blue LEDs present on the facade as indicator of the level of energy remaining.
This new product incorporates the new iSmart technology to optimize the intensity delivered according to the different connected devices and reduce the loading time of those çi.
The 7800 mAh allow 2 ~ 3 charging my phone (iPhone 5s) sufficient to compensate for the severe lack of autonomy of this one. Indeed the small size and relatively low weight of the product is a real asset in a jacket pocket or a bag, this battery goes everywhere.
This battery over my USB cable now follow me to each of my trips.
