Abstract

A portable charger is provided for charging one or more electronic devices simultaneously from a rechargeable internal battery. To accommodate multiple electronic devices, a portable charger unit is combined with multiple connectors for connecting to more than one electronic device, as necessary. For example, the charger unit can include at least one power output for connection to electronic devices via connectors or charging cables, including a squid connector providing multiple connection interfaces adaptable to a variety of electronic devices. Alternatively, the charger unit can include two or more connector cables connected to the charger unit and stored within the charger housing for connection to electronic devices when needed. An adapter unit is provided for connection to the charger unit for recharging the internal battery of the charger unit.
