Introducing DURAGADGET's new dual power bank charger for your GoPro HERO 4 batteries, plus any other USB powered devices.

The included Micro USB cable allows you to charge the power bank through a matching USB power source e.g. a laptop. It can also be used to charge another device such as a smartphone or tablet through the power bank. The power bank is capable of charging two GoPro HERO 4 batteries and one other device simultaneously. The power bank also features a handy, built-in LED flashlight located at the top of the device - simply press and hold the power button for 3 seconds to turn on and off.
