This is an Xgimi MOGO. I bought it a few years ago, but I think the operating time is about 10 hours. There is a dent in a part of the silver exterior. It's hard to see in the photos. There is a chip in the sticker on the bottom. Above all, the auto-focus is excellent. Also, Android TV is easy to use, and it's very convenient to carry around, so I've found it very useful. ★Product Description ・XGIMI MogoSeries Auto Focus Harman 　Small projector Kardon speaker ・Reference price: ¥44800 ・Awarded all four of the world's most prestigious design awards High-cost-performance auto-focus portable projector ・Not only a projector, but also a wireless speaker when connected to a smartphone via Bluetooth! ※You can enjoy more than 200 songs on a single full charge ・Keystone correction function within ±40 degrees, auto-focus ・Wide compatibility, large capacity battery ・210 ANSI lumens, 100" large screen, 4k compatible ・Sound by Harman-Kardon ・Android TV 9.0, 3D technology compatible ・Brightness: 210 ANSI lumens ・Resolution: 960 x 540 pixels ・Lamp life: Approximately 30,000 hours ※If used for 8 hours a day, it will last for over 10 years ※Equivalent to playing over 20,000 movies ・Body size: 14.6 x 10.55 x 9.45 (cm) ・Weight: 0.9 (kg) ・Aspect ratio: 16:9 ・Display technology: 0.23 inch DMD DLP ・Keystone correction: Auto vertical and manual horizontal ±40 degrees compatible ・OS: Android TV 9.0 ・Accessories: Remote control, AC adapter, charging cable, instruction manual and warranty card
