A combinational charger is used as a spare power source of a hand-held electronic device and also used for charging the hand-held electronic device in a DC way. The combinational charger comprises at least a rechargeable battery, a charging connector, a transmission interface and a switch. The charging connector is movably engaged with a power source port of the hand-held electronic device. The transmission interface is movably engaged with a connection interface of a host system to capture power via the connection interface. The switch is used to switch the rechargeable battery to the transmission interface to let a power source on the connection interface charge the rechargeable battery, or switch the rechargeable battery to the charging connector to let the rechargeable battery charge a battery of the hand-held electronic device.
