Can charge mobile phones.
USB sockets are a newly emerging socket that can intelligently identify computers, mobile phones and other electronic products with USB interfaces. When choosing, it is best to choose a USB socket with an indicator light. The indicator light can show whether the contact is good. And whether the internal lines are smooth, it plays a warning role in terms of safety. And you can choose a USB socket with a button or automatic on and off, so that the USB does not need to run for a long time, consume power, and generate heat. And all sockets must be able to pass the 750°C glow wire test, which means that no flame will appear on the socket shell when encountering an open flame.
