We have a couple of the lap 12VDC blankets in our POPUP setup. Great for sitting and watching HDTV in the evening...
Mine draw around 4 AMPS when kicked on by the thermostat... I have a couple of those BLUE SEA 12V sockets installed inside my POPUP setting areas.
I had 120VAC models Lap Blankets before these but they got lost along the way somewhere. I used these with my "DUTY"- Always ON 600WATT Power Inverter when camping off grid....
Great item to have around actually... Wife loves them...
