To address the low autonomy of my Lumix GM1, this charger is perfect accompanied batteries. Fast charging, efficient battery (slightly faster than originally discharged), full compatibility. The battery is a hair thicker than the original and slightly green in the svelte GM1. But it can be removed without problem by tapping a little. The charger is equipped with all the connections needed to recharge everywhere: Power, USB, car ... Awesome and unavoidable. Remains to be seen over time, but since the price of all is that of a simple battery Pana original, it is not too worried.
