Your phone auto-rotates, and now your projector can too! With Auto-Portrait technology, the C250i is now the world's first portable projector that lets you change your projection orientation on the fly. No need to mess with settings or the content - just stand it up, and the Acer C250i will automatically remove those pesky black bars when you enter portrait mode. Easily take your projector with you wherever you go. The exclusive design saves space while also allowing for fully flexible 360 degree any-angle, rotatable projection without even needing a stand. A 100” image of pure beauty in 1080p Full HD looks so real, you'll swear you're looking out the window. Images appear brighter and more vibrant thanks to the exceptional colour saturation provided by the LED source, known as the Helmholtz-Kohlrausch effect. Enjoy your content anywhere - without needing to take an extra speaker. Set the tone with full, vibrant audio from the on-board Bluetooth speaker enhanced with Acer TrueHarmony and ensure your movies come to life, songs have more depth, and games are more engaging. Enjoy full-length feature films without recharging with up to 5 hours of renewable battery life. Use it as a power bank to charge your smart devices. Break free from the clutter of wires with easy wireless projection options and wireless dongle design. No more worrying about battery life - simultaneously charge and project from your phone at the same time thanks to the USB Type-C port. Use this projector as often as you like and for as long as you like; with a 30,000-hour lifetime, you won't be needing a replacement any time soon.
