Review on Fast Heating Portable Car Heater 12V 150W - Defroster & Defogger, 2 in 1 Cooling Fan - Winter Car Heater, Easy Plug Into Cigarette Lighter by Shawn Jimenez

I had very high expectations for this product but was very disappointed. I was hoping for a higher heat output that would actually defrost the windshield. The air that blows is barely warm and has very little power, unlike a cooling fan which has much more power. I need products that really work because my car doesn't get warm and blows warm air out of the vents when parked. This makes it difficult to work when the windshield is icy and I have to go to work. I am very disappointed and was looking for something to relieve the cold morning.
