Portable power charger with power input and power output connection interfaces
A portable charger is provided for charging electronic devices from a rechargeable internal battery. To accommodate multiple electronic devices, a portable charger unit is combined with multiple power output connection interfaces for connecting to more than one electronic device, as necessary, including connector cables attached to the charger housing or power connection ports. The charger also includes at least one power input connection interface for recharging the internal battery from an external power source, including an AC wall plug interface and a DC car charger interface, each connected to the charger housing and movable between a retracted, storage position and an extended use position. The power output connector cables can also be stored within storage cavities formed in the charger housing when not in use and extended therefrom for connection with electronic devices in need of recharging. The power connection ports can act as power inputs, power outputs, or both.
