Case For Portable Electronic Device With Integral Detachable Power Converter And USB Connector

摘要

A case for portable electronic devices is disclosed, providing physical protection from abrasion and mishandling and also including an integral power conversion module with integral ac power mains blades and a USB connector and small form factor. The power conversion module with integral USB connector is provided to recharge the internal batteries of the portable electronic device and is stored within the outline envelope of the case when not in use. The power conversion module is removable from the case for connection to a wall power receptacle or a mating USB connector on another device, and is connected to the case by a retractable cord. The power conversion module ac power mains blades are retractable to minimize the overall volume when stored within the case envelope.
