These USB ports on the RØDECaster Video are mainly for data transfer and connectivity, supplying a voltage of 2-5v, which is lower than what most external devices need for optimal performance.
To ensure consistent power for devices, it's best to use a dedicated power supply rather than relying solely on USB-C ports, which may not provide enough power for high-demand devices.
