Sleep tight and be warm anywhere you go. Our 12 volt warming pad lays on top of the mattress, under you. Since heat rises, not only will it keep your whole bed warm, it saves a ton of energy. Our 12 volt warming pad conveniently plugs into your cigarette lighter. Pre-warms bunk and gets rid of dampness. Heat soothes and relaxes tired back and legs. Helps lull you to sleep. Keeps you warm all night without idling the engine. No more engine noise, vibration, or exhaust fumes.
Automatic Comfort Control thermostat regulates heat based upon the setting you select (1 - 7). It adjusts the heat in the bunk for any change in cab temperature. As the cab cools, it supplies just the right amount of extra heat to keep you comfortable.
Highly Efficient - the "on the mattress" system with automatic Comfort Control converts 98% of the battery power consumed to heat. Average current usage is about 3 amps. Similar to leaving a few clearance lights on. Our Electric Bunk Warmers do not cause battery or starting problems.
Our 12 volt mattress warmers are awesome electrical wonders that resemble electric blankets. They differ from electric blankets mainly in that they are under you while electric blankets are over you. The difference is crucial. Since heat rises, the 12 volt mattress warmer applies more heat, more evenly to you, the sleeper, because it is under you. Less heat is dissipated into the air, because the heat is also trapped by a light blanket over you. Thus our 12 volt warmer uses half of the electricity used by an electric blanket and warms twice as nice!
Don't worry that much about running down your battery with our warming mattress pads! The Comfort Control thermostat cycles the warmth on and off at short intervals. It pulls full rated amperage only when cycled on. The amount of time it is cycled on versus off depends on the Comfort Control setting and room temperature. Experience has shown that on the average, it is cycled on less than 50% of the time. Since rated amperage listed is maximum if it is on 100% of the time, the average load on the battery system is 50% or less of rated amperage (reports of battery problems have been negligible over the 30 years we have offered the 12 volt products).
