Portable projectors need to adapt to a variety of environments. With a built-in intelligent sensor that automatically sets autofocus, keystone correction, and screen fit Anker's Nebula Mars 3 does so in just 3 seconds. It has a 1080p resolution with a max screen size of 200 inches and AI that automatically adjusts screen brightness, up to a max of 1000 ANSI Lumens. A built-in 40W speaker with Dolby Digital Plus removes the need for external speakers, the battery offers up to 5 hours of video playback and can serve as a power bank for other devices, and Android TV 11.0 removes the need for an extra streaming stick. The unit is also IPX3-rated for water resistance and has a built-in stand, lens cover, and handle.
