Most Popular Interior Vehicle Heater for 2019 Toyota RAV4

Good tool! Keeps me warm

This heater is being used to supplement an existing heater in a van. I like that it was very easy to install. I also like the physical size of the heater. After using it throughout some cold days in November I felt that it might be best suited for a very small enclosed space, like the size of a tractor cab in temperatures that don't go below 45F. I wouldn't recommend it for an area larger than 300 cubic feet. I can barely feel the heat emitting from the unit when my hand is 6 inches directly in front of it. I went into the purchase with fairly low expectations so I'm glad that I didn't spend more than $[XX] to purchase this heater.

Fast shipping from e-trailer. Wired in a 30 amp socket with it's own fuse to plug this into. Figure engine off 12v --> at 300 watts = 25 amps. engine running 13.8v --> 22 amps. Used the heater in a test today, 25°F. Tested two conditions. 1) engine off: virtually no heat in 150w setting some heat on 300w setting. 2) engine running: amount of heat one would expect at both settings. Apparently it is very sensitive to voltage. bought it to pre-heat the truck interior. Oh well.

The heater could have been fantastic, however after a couple days - run time 2.5 hrs each day - the heater stopped producing much heat. Not sure if it's a short or the heater coil but the unit became a noisy fan that didn't blow much air. Disappointing.
