3 amps at 12V is 36 Watts.
Not going to keep you toasty I'm afraid.
I think I disagree. Not with your calculation, with your conclusion. You are right, it is only 36 watts. The thing is, mattress pad heaters do not need to be as powerful as electric blankets, because they aren't out in the open air. They are well insulated on the bottom, as well as above. The 120 volt one in the sticks and bricks is only 60 watts, and I never use it above a 2 (out of 10) setting.
But I will be sure to let everybody know how well it works after it arrives.
