Abstract: A wireless broadband device includes: a main body and an end cover, where the main body and the end cover are assembled to form a whole; a first battery is carried in the main body and configured to supply power to a circuit of the main body; a second battery is built in the end cover, where a power output contact of the second battery emerges from an inner side of the end cover; the inner side of the end cover contacts the main body; and the power output contact of the second battery contacts an exposed power input contact point of the circuit of the main body, and when an output voltage of the first battery is smaller than the minimum required voltage for supplying power to the circuit of the main body, the circuit of the main body switches to the second battery for power supply.
