Review on 💡 200W Power Inverter DC 12V to 110V AC Car Converter: 2 AC Outlets, 4 USB Ports, Digital Display by Sam Anez

as you can see in the photo it was not installed on my car. It replaced a burned out cigarette lighter in my Airstream Bambi so had to be plugged in. Thanks to the very helpful folks at NAPA Auto Parts in Las Vegas, NM, my installation was a success and the inverter works flawlessly. BUT . . . when I turn off the inverter, only two outputs 110 go off; the four USB ports remain enabled. I was hoping that the whole device would turn off to not use any power. I turn it off to achieve this.
