3000C / 4000 ThermTech Back Seat Heat Plus 12 Volt / 24 Volt DC Heater

ThermTech no longer makes the Back Seat Heat Plus. The closest current equivalent is the Rampage 300-watt back seat heater: like the 3000C, it wires into the vehicle’s electrical system rather than plugging into the lighter socket, and puts out 300 watts. We have left this page up so you can check the specifications against yours. For other ways to stay warm on 12 volts, see 12-volt heaters for cars and trucks.
