Abstract

A rechargeable portable power station with two-way universal serial bus (USB) capable of recharging electronic devices as well as recharging itself. A bidirectional universal serial bus (USB) adapter port that can be integrated into a rechargeable portable power station. The invention can utilize a micro-controller to convert a single USB adapter port into either an input device or an output device. A power station with a bidirectional USB adapter port is capable of recharging external electronic devices, as well as recharging its own internal battery, through the same port. Due to the size of the internal battery of the power station, when used as an output device, the bidirectional USB adapter port will be able to provide many hours of operation before exhausting the power station's internal energy.
