Power GoPro7 on the motorcycle.

Does anyone have experience with GoPro 7 black, which is attached to the motorcycle in continuous operation? Have I installed a USB adapter from 12V to 5V 3A (China import) on the motorcycle, which ends the power supply of the GoPro after a few minutes (reclaimed and replaced, the same again). If a powerful USB port (fixed) is needed, can someone recommend me? Cheaply pay twice 😉 don’t want to experiment anymore. THANK YOU already.
