The Canon R5 C can be powered via USB-C. A USB-C PD (Power Delivery) source, like a power bank or adapter, is needed. The R5 C can hot-swap between external USB-C power and the internal battery, allowing for uninterrupted recording.
USB-C power delivery is considered a safer method than dummy batteries because it offers redundancy (if the external battery dies or the cable is disconnected, the recording won’t be affected).
