A portable heating system includes a rechargeable power source and a heating element electrically connected to the rechargeable power source. The system may include a power management element configured to selectively electrically connect the heating element to one of the rechargeable power source and an external power supply to power the heating element to generate heat. The system may be remotely controlled by a transmitting unit in communication with a receiving unit via a wireless communication path. The receiving unit is configured to receive command signals from a transmitting unit and communicate with a controller configured to control activation of the heating element. The power management element may be configured to monitor incoming voltage of an external power supply used to charge the rechargeable power source and to terminate use of the external power supply when the incoming voltage reaches a cut-off level.
