Abstract

The invention relates to a mobile power source device. The mobile power source device comprises a load connection point , a power source supply circuit, an output circuit, a detection unit and a control circuit; the power source supply circuit provides output current through the load connection point; the output circuit generates output voltage on the load connection point according to the output current; the detection unit generates detection signals according to the output current; the output circuit includes an impedance circuit; the control circuit controls the output circuit to switch the resistance value of the impedance circuit according to the detection signals, so that the output voltage can be decreased, and therefore, the output current can be decreased.

Description

【Technical field】 [0001] The invention provides a mobile power supply device, in particular to a mobile power supply device and a current output method thereof. 【Background technique】 [0002] With the advancement of technology and the diversification of mobile electronic products, it is common to have one or more mobile electronic products. At present, mobile electronic products, such as mobile phones, notebook computers, digital cameras, audio players, etc., all use rechargeable and discharging batteries as the power source during use. Traditionally, users need to convert the indoor AC power into a certain voltage level through the equipped charger (transformer) to charge the mobile electronic products. However, in an environment where indoor AC power cannot be obtained, it will cause difficulties in charging or interrupt the use of mobile electronic products. Therefore, a mobile power supply unit (PowerBank) with a rechargeable battery inside has been developed to suppl...
