We use our smartphones to deal with a whole lot of stuff – make phone calls, check emails, play games, and even pay bills. So seeing an empty battery icon is surely a bummer. The RAVPower RP-PB005 large capacity dual-port power bank contains 10,000mAh power in a compact body, allowing users to refuel their 2 devices simultaneously anytime, anywhere. Both ports are iSmart outputs allowing you to charge 2 times faster. Designed with rounded corners, this power bank provides outstanding and secure feel in the palm of your hand. To top it all off, it's packed with multiple protections so you can power up with optimum safety.
