Abstract

The invention a terminal capable of supplying power for the outside, which comprises a terminal port, a switch circuit, a charging circuit and a battery which are successively connected, wherein the port terminal is connected with the battery by a boosted circuit. The terminal port is connected with a first USB connector or a second USB connector in a plugging and unplugging way. When the terminal port is connected with an external power supply by the first USB connector, the terminal is in a charging status, and the external power supply charges the battery by the first USB connector, the terminal port, the switch circuit and the charging circuit successively. When the terminal port is connected with the other terminal by the second USB connector, the terminal is in a power supplying status, and the battery supplies power to the other terminal by the terminal port and the second USB connector after being boosted by the boosted circuit. The terminal is provided with the boosted circuit on a mainboard in advance, which ensures that the battery of the terminal not only can charge the functional circuits of the terminal, but also can charge other terminals at the same time. Therefore, the mutual charging among the terminals can be realized, and the flexibility of the use of the terminal is greatly enhanced.

Description

technical field [0001] The invention relates to a portable terminal, in particular to a terminal capable of external power supply. Background technique [0002] The use of existing portable terminals such as e-books, mobile phones, etc. is becoming more and more common, but these electronic devices can only be used as device terminals, and must be plugged into an AC power socket for charging through the adapter matched with the terminal, or connected via USB Connect the cable to a computer for charging. At present, the battery of the terminal can only provide power for its own functional circuits. It is difficult to charge the terminal outdoors or without charging equipment. The charging terminal supplies power, and at the same time, other terminals cannot provide emergency power to the terminal through the interface, which brings inconvenience to the user in an emergency. Contents of the invention [0003] In view of this, it is necessary to provide a terminal capable o...
