Abstract

The invention provides a portable large capacity power source unit, which comprises a battery; a multi-joint compatible power supply interface port used to supply power to the battery; a multi-joint compatible power discharging interface port used to make the battery discharge electricity; a circuit board controlling the charge and discharge of the battery and a shell capable of holding the battery, the multi-joint compatible power supply interface port, the multi-joint compatible power discharging interface port and the circuit board. The portable large capacity power source unit is able to adopts a polymer lithium battery, thus the invention has the advantages of the small volume, light weight, convenient carry and able to be placed in the pocket to supply power for the portable electronic equipment at any time as well as any place. The battery is provided with a temperature-rise protection inductive control system of overcharge, overdischarge and overcurrent inside, thus prolonging the service life and improving the application safety.

Description

technical field [0001] The invention relates to a portable large-capacity power supply device, in particular to a portable large-capacity power supply device for supplying power to portable electronic devices such as mobile phones and personal digital assistants (PDA). Background technique [0002] Consumers who use mobile phones, personal digital assistants, often experience low battery power in places where household AC power or car power are not available. Because traditional power supply equipment cannot be used without AC power or car power. For this reason, existing a kind of way is to be provided with fixed mobile phone charging station in some occasions such as the airport, is equipped with multiple mobile phone power supplies for mobile phone charging. However, using this method of power supply also limits the flexibility of consumers to a certain extent. Also having a kind of way is to adopt dry battery boost to power the mobile phone again, but because dry batte...
