Abstract
The utility model provides a portable power supply device, comprising an input circuit, a charge circuit, a protection circuit, a rechargeable lithium ion battery, a control circuit, a transformer circuit and a bridge style inverter circuit. The input circuit converts an outer power supply into a DC voltage and the rechargeable lithium ion battery is charged by the input circuit though the protection circuit. The control circuit converts the DC voltage sent out by the rechargeable lithium ion battery through the protection circuit into a pre-set DC voltage for external output. Simultaneously, the bridge style inverter circuit converts the DC voltage into pre-set AC voltage for external output. The portable power supply device can provide multi-lines of AC and DC voltage output, and the volume is small and the weight is light, the energy consistency and the reliability is high, and the use is convenient and easy.
Description
Technical field
The utility model relates to a kind of mobile power supply device, in particular for digital products such as notebook computer, mobile phone being moved the device of power supply.
