Abstract: The present invention relates to a device capable of achieving fast charge and fast discharge of a vehicle emergency starting source, including an input module, a voltage input adjustment module, a battery module, a voltage output adjustment module, a first output module, a second output module and a third output module. In the device, SC8801 is adopted, which is capable of achieving an input power up to 24 W, thereby improving the practicability of the device. Meanwhile, Type-C QC3.0 protocol is adopted in the first output module, USB QC3.0 protocol is adopted for the second output module, and Type-C PD protocol is adopted for the third output module, to meet different charging needs and improve the practicality of the device. Moreover, the voltage input adjustment module can balance and convert the power, thereby reducing power consumption and loss, improving electricity conversion rate, and improving practical value of the device.
