Abstract
The present invention provides a new and useful apparatus for charging battery powered electronic devices using a rolling means. The rolling means transfers mechanical energy from a plurality of wheels to a generator by way of a gear ratio. The generator in turn yields electrical energy that is later transformed via integrated circuitry into viable power for the purposes of charging an optional internal batter or that of an attached device. This apparatus does not limit the user's mobility and can be used in everyday settings. The apparatus can be an integral part of a piece of luggage or added to an existing hand cart. Additionally, the apparatus can have a connection for a DC input to charge the internal battery when the apparatus is not in motion.
