GEPRC GEP-C1 is a two-channel charger for 1S HV Lipo battery. The charger has a USB-C input and can thus be powered from a power bank, laptop or phone charger. The GEP-C1 can charge two batteries at the same time, each with up to 1A. A PH2.0 and A30 connector is provided for each channel (do not plug batteries into both connectors at the same time). The charger has a beeper to alert you when the battery is finished charging. A handy feature is also measuring the voltage of the battery without having to plug the charger into the USB connector. Just plug in the battery and the voltage will be displayed on the screen.
