Review on Premium BESTEK 400W/500W Inverter with 4 🔌 USB Charging Ports & 2 AC Outlets: Upgrade Version by Chris Hernandez

I bought this to upgrade a couple of 150w cigarette lighter models that couldn't crack the heating pad connected to it. This tank model. The fan sound isn't bad, but it sits behind the second-row seats. I expect rear seat passengers will complain about fan noise, but we rarely carry passengers. No detectable electronic noise in stereo systems, scanners and mobile/portable radios. I would/probably buy another one for a second car or as a gift.
