Abstract

The present invention relates to a mobile communication device with current-limited charging function, which consists of an energy storage unit, a first power connector, a first charging circuit, a second power connector and a second charging circuit. The first charging circuit is electrically connected with the first power connector and the energy storage unit and the maximum current of the first charging circuit is not more than a set value; the second charging circuit is electrically connected with the second power connector and the energy storage unit and the maximum current of the second charging circuit is more than the set value. The mobile communication device with current-limited charging function adopts the structure; therefore, when the charging is carried out through different chargers, the mobile communication device can start the corresponding charging circuit according to the current range provided by the charger so as to prevent different charging currents from damaging the mobile communication device.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to the technical field of charging mechanisms for mobile communication devices, in particular to a mobile communication device with a current-limited charging function. Background technique [0002] Please refer to figure 1 and figure 2 As shown, general portable electronic devices such as mobile communication devices, mobile personal assistants, mobile audio-visual devices, etc., are used to charge the energy storage unit. The device 1 is electrically connected to the external power supply unit P, and the common external power supply unit P is usually a charging stand, a travel charger or a car charger, etc.; the other is a Universal Serial Bus (USB) power connector 11, which is also arranged on the mobile communication device 1, but the external power supply unit electrically connected to the USB power connector 11 is the computer 2, and is electrically con...
