The Hedbox RP-DC50 Digital LCD Dual Battery Charger Kit with RP-DVBG6 Battery Plates is a two-bay solution that safely charges your batteries while providing a 2.1A, 5 VDC USB output. Two PANASONIC VBG/DU-compatible battery plates are included in this kit. 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.
