Benefits of technology

Inventions have two main benefits - they ensure stable connections between regular computers without requiring any extra equipment like batteries or other energy sources for their operation; while also being small enough to fit into limited spaces around it when needed.

Problems solved by technology

The invention relates to improving the efficiency at which electronic equipment uses its own battery without being able to find another charger due to limited power availability. This means users have trouble connecting their batteries properly even after they leave them outdoors because no charging station may exist near where these batteries were previously connected. Additionally, this technology allows users to use multiple ports simultaneously instead of having one port available all along time.

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.
