Abstract

The invention discloses a rechargeable-type USB (Universal Serial Bus) auxiliary power-supplying device, which comprises a shell part, a USB-interface state-detecting part and a control-circuit part, wherein the shell part comprises a shell, a female USB interface, a male USB interface, an upper cover plate and a lower cover plate; the USB-interface state-detecting part comprises a slide block, a reset spring, a stop block, a miniature travel switch and a baseplate; the control-circuit part comprises a charging circuit and a boosted circuit. The device has the advantages of no need of an external power supply, small and exquisite size and no occupation of excessive desktop space; when the quantity of user USB ports is limited, a host computer is farther from a power-supply socket, power-supply jacks are insufficient, and a double-ended USB connecting wire is not provided by mobile equipment, only the auxiliary power-supplying device needs to be connected, so that high-power USB mobile equipment can be conveniently used.

Description

technical field [0001] The utility model relates to the field of power supply equipment, in particular to a rechargeable USB auxiliary power supply device to ensure that high-power USB mobile equipment can be smoothly connected to the USB interface of a common computer. Background technique [0002] According to the technical specifications of the USB interface, the current output voltage and current of the USB interface are: +5V, about 500mA. When using a device with high power on a single USB interface, such as a mobile hard disk, it is often found that the device cannot be found, the device cannot operate normally, the file is not easy to read, only small files can be copied but not large files, copying files is easy to crash In other cases, especially for 7200 rpm high-speed mobile hard disks (2.5 inches), the startup power often needs 5W, and a single USB interface cannot meet the power supply needs. In order to solve the problem of insufficient power supply, a double-...
