I needed 110 (household) power in my car, so I bought a less than quality product. After only 6 months or so, I was driving and heard a loud pop come from my trunk.
I pulled over, opened the trunk, and there was smoke coming out of the old power inverter. I looked around, and found these Gems. I had some of their products in the past, so I took a deeper look.
For my needs, I settled on the 2000W device, but all of them are great quality. The higher end ones bluetooth, so you can download an app, and monitor your cars voltage, as well as the wattage your device is putting out. All in all, a pretty great deal.
Mine has 4 outlets, plus 2 USB outlets for my phone and tablet. They are super easy to install.
