1 Answers
Below are the specific reasons why the USB port in a Cadillac cannot charge: 1. Blown fuse: The fuse for the vehicle's USB port may have blown. Refer to the vehicle's user manual to locate the corresponding fuse. If it is found to be blown, replace it with a spare fuse promptly. Damaged data cable; loose charging port springs on the phone, leading to poor contact. 2. Insufficient current output: Check the application range of the USB port in the vehicle's user manual. Generally, USB ports used only for data reading provide a current of 0.5A, whereas a phone charging port requires at least 1A current output.
