Abstract:
A rechargeable electric device is provided that includes each of rechargeable batteries and disposable batteries. The rechargeable batteries are embedded within the device, and the disposable batteries are stored within an easily accessible compartment of the device. The disposable batteries may be used to either charge the rechargeable batteries or to run the device as a reserve battery option. The device more efficiently uses the disposable batteries by charging the rechargeable batteries when the device is turned off. The device includes an indicator to monitor the power level of the rechargeable and/or disposable batteries. The device can be powered by the rechargeable batteries until they are depleted before automatically transitioning to the disposable batteries as a reserve power supply. The rechargeable and disposable batteries may also be used as a "power pack" for charging other devices such as cell phones.
