The Patona Dual LCD USB Charger for Canon LPE6 LP-E6 is ideal if you want to charge multiple batteries at the same time. You can also charge batteries of different capacities at the same time or charge a third-party device such as a cell phone, tablet, smartphone or camera via the built-in USB output. The built-in charging technology is controlled by a microcontroller and prevents overcharging or overheating. It also automatically recognizes the required voltage of the inserted battery. To cover as many application areas as possible, the charger has 2 different charging modes, “L” for normal charging that does not damage the battery and “H” for fast charging.
