Designed for flexibility and portability, the cable can be connected to any 5V USB power source such as wall plugs, power banks, or USB hubs. For best performance and stable output, we recommend using a 5V/1.5A or 5V/2A power bank. It provides consistent and safe power — perfect for long video recordings, studio use, or streaming setups. Note: This cable does not charge internal batteries. It provides direct power to the camera when plugged into a USB source. Make sure your power bank or wall adapter supports at least 5V/1.5A for optimal performance.
