Abstract
The present invention provides an electronic device recharger that has utility in converting a portable electronic device from disposable battery power to rechargeable battery power without resort to modification of the device circuitry. The recharger includes a power adapter, a recharger terminal, a battery pack and a replacement battery cover. To utilize the recharger as according to the invention, the device battery cover and the disposable batteries are removed from the device and replaced with the battery pack and the replacement battery cover. The power adapter is plugged into the wall and the connector terminus is plugged into the battery pack through apertures formed in the replacement battery cover. The power adapter and connector terminus are in electrical communication such that the power adapter provides conditioned power to the connector terminus which in turn provides power to the battery pack and the device. A light emitting device is provided on the connector terminus and indicates the charging status of the battery pack.
