This is an arwin 10.1-inch portable DVD player that can play DVDs and SD cards. I bought it a few years ago, but I haven't used it much and have kept it in storage. I have only checked DVD playback, and it worked without any problems. I haven't checked other details, but I hope you can understand. You can also play it in your car using the cigarette lighter power supply. - Brand: arwin - Model: 10.1-inch portable DVD player - Accessories: Remote control, AC adapter, instruction manual - Connection cables: Cigarette socket charging cable, antenna cable - Screen size: 10.1 inches - Playback media: DVD, SD card Thank you for looking.
