needing help with ps2/portable dvd player idea.

[gameguru]

So i have a random ps2 and a portable DVD player.
here is some things that i have with the DVD player.
- x2 Li-ion rechargeable battery packs
- A Venturer portable DVD player
- has audio and video plugins
- case that has 2 bigger speakers built in that plug into
headphone jack that runs off of 9v battery
-car charger

Thing is i have lost the house charger to the battery's so now
that's where im lost i have no clue where to go from there and
the way it charges is when the battery is plugged into
the DVD player and the ac adapter is plugged in so any idea's?
