Abstract: A power supplying method for a wireless network terminal and the wireless network terminal are disclosed. The method includes: detecting potential information of two power lines of a USB (Universal Serial Bus) interface of a wireless network terminal; determining, according to the potential information of the two power lines, a type of a power supply device that is connected to the USB interface; and when the type of the power supply device is a power supply device having a communication capability, controlling the wireless network terminal to work in a predetermined communication mode, so as to implement power supply for the wireless network terminal by using the power supply device. With provided technical solutions, a cost of the wireless network terminal can be reduced, and a battery with a relatively large size is not needed, thereby facilitating miniaturization and integration of the wireless network terminal.
