Have you ever made a point of going in to a coffee shop or restaurant just to use a plug to charge your smart phone? Well, if you get yourself a RavPower external battery charger you won’t have to worry about missing calls or updating facebook during your travels ever again. With two USB ports you can charge two devices at once and it even charges iPads.
23000mAh of power keep you and your gear going, and going - and going. Add 1100% more battery life to an iPhone, 700% to your large-capacity phone (like a Galaxy S4), or 150-350% to your tablet (depending on its battery capacity) - all away from an outlet. What's more, the added energy efficiency gives you 10% more usable power than the previous generation and many standard alternatives.
