Abstract: Vaporizer includes a housing defining a substance retaining compartment, a heating element, a mouthpiece communicating with the compartment through which vaporized substance is discharged from the housing, and a rechargeable power storage unit that provides power to the heating element to enable the heating element to heat the compartment when activated. The housing includes a first port that mates with a first cable connectable to an electricity supply, and a charging unit interposed between and electrically coupled to the first port and the power storage unit. The power storage unit is charged when the first port is mated with the first cable connected to the electricity supply. A second port is electrically coupled to the power storage unit and mates with a second cable connectable to a power using device. Electricity from the power storage unit powers the device via the second port and the second cable.
