Hello,
I recenty assembled a pair of ski boot heaters to plug into a 12v socket in my truck. I am not an electrical engineer or designer, but the concept seemed simple enough: I used two 12v RV water heater strips (silicon strips) wrapped around aluminum flexible conduit with a heat shrink wrap. These are wired in parallel, and draw 150 watts each and routinely blow the 20 amp and lessor fuses in other vehicles. Using an online calculator, it appears that my device is drawing about 25 amps, hence the fuse problem. I beleve that I can reduce the amperage drawn using a resistor, but I dont know how to size or source one that would work. Can anyone help me out?
Thanks.
