300 watts, 25 amp, 12 volt DC. (The last photo of the product box, if you zoom in on it, it shows "300 watts") The heater (all) are likely protected against overheating to prevent damaging themselves. *With all heaters, use caution that they aren't blowing on/pointing at anything very close to them, as that could cause damage. Example, the seat, papers, clothing, etc. Continuous use won't damage anything except it will drain a vehicle battery (an old one much faster) so the vehicle engine should be running to help prevent that drain. It could also be used for a short period, turn it off, use it again, to minimize that drain, but you'd still want the vehicle engine running. This heater uses about the same power as 5 halogen off-road lights. That high power is why it has a high heat output.
Sorry, there was a problem. Please try again later.300 watts Continuous use should not cause damage to a battery provided the engine is operating. If it isn't, it certainly could, and would likely drain the battery completely as vehicle batteries are not mad for that load.
Sorry, there was a problem. Please try again later.At 12.0 volts, it draws 325 watts, with 300w coming out as heat. (the rest heats the power wires) At 13.8 volts, it draws 31 amps (430 watts), with 400 of those watts out the heater.
Sorry, there was a problem. Please try again later.My installation will use a completely separate battery, a Dual Battery System. A Dual Battery System will isolate the second (auxiliary) battery from the starter battery. This will ensure your starter battery always has enough power to start the car in the morning. You might only need something as simple as the Smart Solenoid or smart battery isolator.
