DVP-FX780 Charging Cable and Instruction Manual Included This is a Sony portable DVD player. ★ I charged it for 2 hours and tested watching a DVD without sound using the built-in battery. The battery indicator went down by one bar out of three in about 58 minutes. See the photos. Since the DVD was 1 hour and 20 minutes long, I confirmed it played that long, and I think it can run on battery for more than 1.5 hours, so you should be able to watch a 90-minute movie or anime video. ★ A cigarette adapter is also sold separately if you want to use it in a car. This portable player was purchased from the Sony Store for my child to use to view materials for their lessons, and it was used for about 1 hour every other week for about 3 years. It has been stored for about 6 years, but I tested it for playback to confirm its operation before listing it. The items included are: Portable DVD player本体 AC adapter Instruction manual Thank you.
