Do Portable Dvd Players Kill Your Car Battery?

We have dual screen Phillips portable dvd player and the last few times we have used it, we have noticed that after using it the day before for a couple of hours, we have trouble starting our car. It is plugged into the adapter provided by the mini-van. Has anyone else had this problem? Is there a solution?

Suggestion:

it is like leaving your parkers on for a few hours, there is a bit of draw off the battery. you could upgrade your battery to a bigger capacity or you could have an accessory battery that only the screens run off, you could rig it up to the charging system with the appropriate items so it will charge itself.

how old is your battery? maybe it is a sign your battery is a little worse for wear.
