Ravpower products are generally well presented and good quality, this one is no exception to the rule. The box is nice and well presented. I tested it for two weeks now. This relatively lightweight product provides a backup battery when driving. What I really like is the ability to sarrêter when full or when it has completed the device to reload. IF we compare this case to the next model (the one at 16,000 Ah, model: RP-PB19), I find it unfortunate that there are no white like its big brother. It has no built-in light and an output port, but this is not a problem because it will not have the ability to charge multiple devices simultaneously. I regret that there is no carry bag because its purpose is clearly to this use.
