This is a portable projector with built-in Harman/Kardon speakers. I've used it for about two years. Usage was about 2 hours, 1-2 times a week. Since I've used it connected to a power outlet, I believe the battery has little wear. There are no noticeable scratches or stains, and it works well. The power cord is included, but it has been repaired with tape. Please note that the remote control is not included. Please understand that this is a used item before purchasing.
