Review on 🔌 Zerostart 2600900 Portable Electric Car Heater - Interior Compact Plug-in Warmer, 3,000 BTU, 120V, 900W by Jay Liu

I use this with a street timer that is set to run for a few hours before I go to work in the morning. I never have to clear ice or snow and my car interior is always warm and dry. The first 10 minutes of my morning drive is much safer as the inner windows don't fog up and my engine heater has enough time to do its job. We often have 1/4 inch ice on our windshields in the winter and this little heater unmistakably melts it off.
