Author: steveng Xtreme Heaters are available in 220v, 50hz for international applications. Our 220v heaters are provided with a power cord that is not terminated. The appropriate plug for your geography will need to be purchased separately. Was this answer helpful ? Yes (0) / No (0) Can I also put an Xtreme Heater in the cabin for extra protection? Would it be safe? Is it DC power (connects to battery) or AC (plugs into power outlet)?
