The charger works well. The portability is the best feature about it! The colors for charging on mine are also backwards.
...very convenient and small charger. Perfect for throwing in my backpack while traveling.
The flashing lights on mine operate the opposite of what this page indicates. Just an FYI.
Mine flashes red/blue when no battery is being charged. Flashes red only when charging.
