Can be used in Car and on mains power.

This system allows independent control over the DVD play from the screens.

Use cases
In a car
Someone in the front passenger seat controlling the DVD player while kids in the back just watching, great for younger kids!

Hotel
Keeping the kids entertained at a hotel, while you watch something else.

Camping
With electrical hook up, this could be a lifesaver for a moments peace :)

No remote control with this, but it works fine using the buttons on the DVD player.
