This wall charger is ideal for the Hero 3. The two USB ports are needed: first to charge main battery via the camera the second can be used at the same time to charge the battery BacPac or the WiFi remote.
DO NOT CHARGE BATTERY BACPAC WHILE IT'S ATTACHED TO CAMERA!!!!!!
The interchangeable plugs are easy to fit and remove and very useful for France, Germany and many other EU countries(USA plug is also included).
The charger is a 'must have' item, although there are other ways to charge the batteries and WiFi remote I've found this charger is the best way.
