Cobra Power 500W Power Inverter, Portable – 500-Watt Car Charger, 2 Grounded AC Outlets, 2 Fast Charge USB Ports and Remote Controller (CPIALCDG1) Compatible CPI500W

so far so good. worked as intended to run a small CNC key cutting machine and a key optical scanner

Very easy to install. Has all the functions that I needed. No noise that I can hear. Mounted it up under my seat in my 2017 ram 3500. Very good quality. Charging speed if awesome. Love the fact that it has an USB port also. Very quick shipping.

Just a word of warning to start off, even though this is a 500 W power inverter, you have to wire it directly to the battery in order to achieve that. If you use the cigarette lighter cable, it is only rated for 150 W. So be aware! Having said that, I bought the necessary size cables 5 AWG, 60 amp fuse, and wire loom to protect the wires, installed it in my work truck turned it on and worked flawlessly. All told I was in for around $100.

Bought based on reviews and the brand but it stopped working about 6 weeks after I got it and of course after the return date passed. Waste of money!!!

I bought this for our road trip from St. Louis to Orlando. I was able to run my laptop and charge tablets. It was nice to be able to plug it into the 12 V cigarette outlet and not have to run a heavier gauge wire into the cabin of the vehicle. It does have a low voltage alarm, which will sound and shut itself off. This really only occurred when we would start the car so just make sure that it’s off prior to starting.
