Abstract

A portable charger is provided for charging one or more electronic devices from a rechargeable internal battery. The portable charger includes wireless power transmission components, such as a transmitter and a receiver for recharging the charger as well as electronic devices via wireless power transmission methods. The portable charger also includes at least one power connection for connecting the charger with an external power source, or at least one electronic device, or both, for direct charge connectivity. The power connection can be a power connection port or a power connector cable, attached to the charger housing, each capable of acting as a power input, a power output, or both. A processing unit controls operation of the charger for wireless and direct charging.
