12V Car Auxiliary Heater, 4 Ports Universal Underdash Compact Auxiliary Heater, Winter Automotive Air Conditioner for Heating&Defrosting

One of my food truck is one of the older truck that the heater just doesn’t work anymore and I bought this to replace it.PROS:– Nice unit– Small and it fits right on the dashboard or in the front of the truck– Pretty powerful fan– Warm– If you don’t use any of the duct hose, it’s blowing pretty powerful.CONS:– The duct hose was poorly made. Put them on and the came off easily. Ended up getting the aluminum duct hose for them.– Once connected, the fan doesn’t appear to have enough power to push the hot air through those four hoses.– Need to be very creative on how and where to install it or you are going have one ugly spider look-alike heater on your dashboard.OVERALL:I bought this heater mainly to keep the windshield warm during snow or raining season so it doesn’t fog out. It seems to do the job. I wish the fan is a little bit more powerful so I can at least warm my feet, hands, while keeping the windshield clear of snow build-up, etc.
