It doesnt work. First I went to screw it on. To do that you have to remove the mount, which the made to snap on. It broke. So I used the tape and mounted it on a piece of 1/8 inch thick piese of aluminum. Pluged it in. Very weak fan. At 20 degrees.it gives 5 degree temperasture rise with a instant read thermametor. Not enough to do any good . Used it twice. Now sitting in garage

I actually liked this heater. I want to like this heater because it works very well.. and it still does, but the face melted.
It only runs a few minutes at a time too as I have it connected to a Digiten DTC102 Temperature Controller, so I don't understand the problem here- it's mounted on a bracket with plenty of space around the fan and the front for airflow.

While this isn’t quite powerful enough to melt the snow off of the windows of my Ford Excursion, it does do a nice job of keeping the frost away.
Be aware, however, that if it’s wired in with the block heater it may melt the plug on your extension cord. Running a separate plug seems to work fine.

Love these little heaters. We use them inside aircraft cowlings to heat them up before flying up here in Alaska. If there is space you can even mount the bracket so it’s well placed and then just remove the heater before flight.

Best in truck heater I have used. I live in Alaska and Have a 1999 Dodge with a Cummings. So I plug it in when it sits outside. I have the block heater and this heater wired into the same plug. It keeps all the snow and ice off the cab of the truck. It also keeps the inside warm. After one full year it is still running strong.

Thank you very much for the on time delivery of the heater. Product was purchased for my sons birthday of Dec.13 and has arrived well before. This heater is the 3rd one I’ve bought and the other 2 were installed in my vehicle and my wifes car and all work very well. The 1st one was originally installed in a 1988 Dodge Dakota then transfered to my present vehicle after 2008. Thank you again and have a blessed Christmas.

No more scraping. Works great. Mounted mine on a board and stand it up against the console on the hump when I plug it in at night. Windows are clean in winter Illinois.

I reside in SE IL. I plug it every night and my car is nice a toasty when I leave for work. Best of all my windows are crystal clear. The quality is worth the price. I mounted mine on a 1 X 6 X 1.5in board and lay it between my seats on the hump facing the windshield. I put all the heaters cord in the seat and close the door on the All- Weather extension cord. Thanks Kats

this heater requires more power then the average vehicle produces. It runs fine on household current.

The vehicle will require a 120 volt AC outlet for the heater to work.

See what our Experts say about this Kats Heaters Vehicle Heaters
- Interior Car Heater With Thermostat Control Hi Tom, that’s a great question and definitely something worth checking so you know exactly what to expect. The Kat’s interior heater part # KH37650 does not have a built in thermostat, so it will not automatically shut off or cycle once it reaches a certain temperature. It’s a simple 12 volt heater that provides constant heat whenever it’s powered on, so it’s essentially just on or off with no temperature regulation. I know that can be a concern if you’re hoping for something that maintains...
view full answer... - Fuse Size for Kat's Heaters Vehicle Interior Heater # KH37650The 150 watt heater part # KH37650 is protected by a 12.5 amp fuse in the connector.
view full answer... - How Long Does it Take for Kat's Heaters Vehicle Interior Heater KH37650 to Heat UpThe Kat's interior vehicle heater # KH37650 will start getting warm immediately and will reach its top temperature is less than a minute. It basically works the same way as a space heater. Electricity runs through coils that get hot while a fan blows the hot air out. That type of design can get hot relatively quick.
view full answer... - Can the Kat's Heaters Vehicle Interior Heater # KH37650 Be Mounted to a Dash BoardYes, the Kat's Heaters Vehicle Interior Heater # KH37650 that you referenced is designed to be mounted on top of a dashboard so it would work well for your friend. It's a little bit bigger than a radar detector in size. It comes with an adhesive pad that you can use for install or install screws. What's nice is that in the summer time you can turn of the heating element of this product and it will blow air just like a regular fan as well.
view full answer... - Cord Length For The Kat's Heaters Vehicle Interior Heater # KH37650Hey Sarah, The cord length of the Kat's Heaters Vehicle Interior Heater # KH37650 is 65" from the base to the 12v plug.
view full answer... - Should the Kat's Heaters Vehicle Interior Heater KH37650 Make Noise when OnThe fan in the Kat's Heaters Vehicle Interior Heater - 150 Watt - 12V Item # KH37650 isn't all that powerful so if you are using it in a running vehicle you probably would not hear it. If you cannot feel any air moving make sure that the outlet it is plugged into has power. If the vehicle is off it may not have power. If the outlet has power and the unit isn't running when switched on then it could be the fuse. The fuse is located in the plug end that plugs into the outlet. Usually you...
