BESTEK 300W Power Inverter DC 12V to 110V AC Car Inverter with 4.2A Dual USB Car Adapter (Grey)

This inverter works very well for simple devices. It makes almost no sound while operating. It doesn't slow down if you have multiple items plugged in, as long as you don't exceed the capacity. It is small and can easily be hidden in the glove box or under the passenger seat.

It works great in my jeep for my dvd player
