The PD-E2 is designed to be smaller and supplies more power than the PD-E1. It can supply constant power directly to compatible cameras via the USB-C connection. Pairing with the DC Coupler DR-E6P frees up the camera's USB-C port.
The PD-E2 can also charge the compatible battery inside the camera. When a compatible battery grip is attached to the camera, the PD-E2 can charge up to two batteries.
