Because a 12 volt, 100 watt heater will warm your tush (which is already internally heated to around 98 degrees) therefore it stands to reason that it will also defrost your windshield (which is much larger than your tush and only at 30 degrees or so) is quite an assumption . . . . and one which has already been proven false by many of us who actually tried doing it

Indeed- the 12V 'defroster' blowers are nigh useless. Something I've learned from my primitive EV conversions is that a steady stream of unconditioned outside air blown against the windshield will prevent fogging, but will not clear it very well, at least in the Northwet climate here around Seattle. So turn on the fan when you get in. That ounce of effort prevents a pound of cure.

The human body produces 80-100 watts of heat on average. Two people in the car provide 160-200 watts of heat. The stock cabin heater is 5,000 watts.

Locker, welcome to the forum, but keep in mind that linking a product in the first post is a good way to get marked as spam. Since your post and link are both on topic, we'll ignore it.


Oh. Okay. Sry for that! And thaks for advice.
