Cinema anywhere. Plug optional. The Byintek UFO U90 Max is the battery-powered smart projector that needs nothing but surface to project on — a 700 ANSI lumen DLP projector with a 20800mAh built-in battery, Google TV (Android 11), auto-focus, 6D keystone correction, dual 10W stereo speakers, and an integrated adjustable gimbal stand that angles the image to any surface. From a garden wall to a bedroom ceiling to a camping sheet to a church projection screen, the U90 Max is the cinema that travels in a backpack.
The 700 ANSI lumens from a TI DLP chip via an OSRAM RGB+PB 4-LED light source is the brightness specification that matters most for a portable projector. 700 ANSI lumens is approximately equal to 7,000 equivalent lumens in older marketing terms — bright enough for normal viewing with curtains drawn or in low ambient light, and usable in shaded outdoor environments in the evening. The 10,000:1 contrast ratio delivers the deep blacks and vivid colours that the DLP optical engine produces. The native 1920×1080 resolution supports 4K input via H.265 hardware decoding at 4K×2K/30Hz, displayed at 1080p native output.
The 20800mAh / 76.8Wh built-in lithium battery delivers up to 3.3 hours in battery saver mode, 2 hours in standard mode, and 1.75 hours in maximum brightness mode. For garden screenings, camping nights, outdoor cinema setups, and indoor sessions away from power points, 3.3 hours of battery saver runtime covers a full feature film. The battery charges via the included DC adapter or USB-C (20V/5A) for compatibility with large power banks.
Google TV (Android 11) on 2GB RAM and 32GB ROM provides the full streaming app ecosystem — Netflix, YouTube, Disney+, Prime Video, and any other app available on Google TV — without a streaming stick, set-top box, or laptop. Chromecast is built in for casting directly from phones and tablets. AirPlay, Miracast, and DLNA are supported for iOS and Android wireless screen mirroring. The dual-band WiFi 6 and Bluetooth 5.0 provide stable wireless connections.
The auto-focus system sets a sharp image immediately without manual adjustment. 6D keystone correction — auto and manual vertical and horizontal correction plus manual corner adjustment — compensates for projection angles across floors, walls, ceilings, and angled surfaces. The throw ratio of 1.2:1 produces a 100" image at approximately 3 metres of distance. Projection size ranges from 30" to 500" across a throw distance of 0.8 to 13.33 metres.
The integrated gimbal stand rotates and tilts the projector body to aim the image at any angle — floor, wall, ceiling, or angled surface — without a separate tripod or projection mount. The dual 10W stereo speakers deliver room-filling audio without an external Bluetooth speaker. HDMI 2.0 and USB 2.0 ports provide wired input options.
