Can the USB port in the car charge a phone directly?
1 Answers
The USB port in the car can directly charge a phone. Below are specific reasons why the USB port might fail to charge: 1. No charging indication on the phone: The vehicle's USB port fuse may be blown. Refer to the vehicle's user manual to locate the corresponding fuse and replace it with a spare if it's blown; the data cable might be damaged; or the phone's charging port spring may be loose, causing poor contact. 2. The phone shows charging but doesn't actually charge: Check the USB port's application range in the vehicle's user manual. Generally, USB ports intended only for data reading provide a current of 0.5A, while a phone charging port requires at least 1A current output.
