While I'm on site, recharging batteries is often not possible. So evenings get packed with constantly petting the charging station; something I don't like. Luckily, GoPro finally managed to deliver its (long promised) new and smart add-on...
|Double strike: recharges two batteries simultaneously.|
Why two of them? Well, with now three HD Heros I don't want to spend my evenings or nights swapping batteries. I'm no battery hero, you know...
The GoPro dual battery charger is a tiny brick with two battery bays. For each bay the charger has its own LED showing the state of charging affairs: while charging, the LED stays amber. When a battery is fully charged, its corresponding LED turns green.

I'm using a 4,2 Amps USB power supply that features two USB connectors. This way, I only seize a single wall socket while loading four batteries simultaneously.
In total, the whole set is no bargain. Yet, it offers a decent quality. In particular, GoPro charging equipment and batteries always makes use of the temperature control through a thermal resistor built into the GoPro genuine batteries, which the chargers monitor. I still have to find third party Hero battery equipment that comes with this safety stuff.
