The Hedbox RP-DC50 Digital LCD Dual Battery Charger with DMW-BLK22 Battery Plates is a two-bay solution that safely charges your batteries while providing a 2.1A, 5 VDC USB output. Two Panasonic DMW-BLK22-compatible battery plates are included. Charge either a single battery, or simultaneously charge two batteries in less time that it takes to charge both individually. The dual-bay charger features interchangeable battery plates, which is helpful when you have more than one battery type in your kit. The backlit display shows battery charge status in both bays, and since it is backlit you can easily see the readout in bright or dim conditions.
The charger supports both standard and boost charging, with boost providing roughly 1.5x as much charging amperage for faster charging. A built-in 2.1A USB power port provides you with the opportunity to charge USB accessories. The charger features overcharge and overheating protection, as well as being able to test for short circuits within the battery itself.
