Abstract: A socket with switches and USB slots includes bottom base, a cover closed on the bottom base and a voltage transforming circuit board fixed in the socket. The voltage transforming circuit transforms voltage of a power source, having an input terminal connected with the power and an output terminal formed with a USB slot. Then the voltage transformed and rectified by the circuit is the same as that of an USB slot of a common computer host, and sent to the output terminal or the USB slot. The cover has a hole corresponding to the USB slot of the voltage transforming circuit. Then an electric appliance such as a cell phone can be charged by connecting one end of the USB power line with the electronic appliance and the other end of the USB power line inserted through the hole of the cover and into the USB slot, without need of using a conventional power line with a large and heavy transformer.
