AMW 7-Inch Portable DVD Player (M-270)
Backup battery
I agree with one of the reviewer about having a backup battery on hand. Even though the battery that came with the unit has a playback time of about 2.5 hours, it just doesn't seem to provide enough playback time when watching an extended movie. The unit shuts down before the movie is over. So, I checked with AMW and they directed me to their website at [...] and they said that they are now carrying an extended type battery which provides a playback time of upto 5 hours. I bought one to replace the existing battery I have (my old one had lost its recharge capability), and it worked pretty good. So, if you need to replace your existing battery or just get a spare backup, I would recommend getting the extended type for this unit.
