A device may include a first connector configured to connect to a portable device and a second connector configured to connect to a power source. The device may also include circuitry configured to provide a first charging current to the portable device via the first connector when the second connector is connected to a power adapter coupled to a power outlet and provide a second charging current to the portable device via the first connector when the second connector is connected to a universal serial bus port of a host device.
