Yaber T2 speaker & battery-powered Full HD projector. I don't think the total usage time is even 10 hours, so I think it's in like-new condition. I reconfirmed its operation for the listing, and it works without any problems. I bought this as a replacement while my main unit was being repaired, but the main unit was repaired quickly, and I hardly used this product, so I'm putting it up for sale. Here's a general description of the product. Please check the official website for more details. [Body Size] Height: Approximately 29.5 cm Depth: Approximately 17 cm Width: Approximately 16 cm [Accessories] All accessories are included, including the remote control and cables. [Input] Equipped with HDMI input. I tried it with my game console 4, and you can send both video and audio with a single HDMI cable, just like a TV. [Focal Length] Minimum projection distance is 1.1m for 40 inches, and maximum is 3.3 meters for 200 inches. [Installation] There are screw holes on the bottom of the main unit, allowing for installation using a tripod, as well as ceiling mounting with the image flipped upside down. [Built-in Speaker] Built-in JBL speakers, and Bluetooth connection with smartphones is also possible. [Built-in Battery] Built-in battery. Can be used even where there is no power supply. [Cable-free use is also possible with optional accessories] You can enjoy video streaming services wirelessly with a dedicated TV dongle. *The product has been initialized and is in factory default condition.
