I bought this connection cable for my kids portable DVD players when we went to Texas for Christmas. It worked wonderfully! You could watch the same DVD on two different players. It works with this player that I bought from Revain: HD JUNTUNKOR 12.5" portable DVD player with 5 hour rechargeable battery, unique dual-use design, 10.1" HD rotating screen, car headrest, remote control , car charger, USB/SD card reader. Just remember that you need to change your player settings for it to work properly. Regardless of which DVD player the disc is in, this cable connects to the AV OUT port on that player and the AV IN port on the other player, if that makes sense.
