It's convenient for watching DVDs or mirroring your smartphone screen in the back seat of the car, but the screen is a bit too large for my needs, so I'm putting it up for sale. There are some minor scratches, but in my personal opinion, it's in good condition. I'm also including an adapter so you can use it at home. Everything is shown in the photos. The following is a quote: [HDMI Input & Slot-in] HDMI input allows you to connect HDMI-compatible devices such as smartphones, Switches, Raspberry Pis, and computers to enjoy high-quality video and audio. You can use it for various purposes, such as watching videos on YouTube. "※Please prepare an HDMI cable separately." Large-screen slot-in 12-inch headrest DVD player, DVDs are automatically drawn in and out, making it easy to insert and remove, even for small children. [CPRM & Region Free] Compatible with DVDs recorded from terrestrial digital broadcasts. Also supports region-free, allowing you to watch not only Japanese DVDs but also foreign DVDs, which is recommended for children's foreign language studies and is practically convenient. An AC power cable is not included, so you will need to purchase an AC power cable separately for indoor use. [AV-IN & AV-OUT & Resume] Resumes playback from the previous point when the power is turned back on. Supports AV input and output; if you purchase two DVD players, connecting the AV input cable and AV output cable allows the same video to be played simultaneously. If the video doesn't display, press the TFT OFF/ON button on the remote control. Various formats can be played via USB/SD card, supporting up to 128GB (FAT32 format). [Headphones Included & Built-in Speakers] Includes wired headphones for stable sound output and good sound quality, protecting children's hearing.
