Verdict

The Anker Nebula Mars 3 Air is a compact, 1.7 kg portable DLP projector featuring native 1080p Full HD resolution with HDR10 support and a brightness of 400 ANSI lumens. It runs on a built-in Google TV interface with native Netflix certification and includes dual 8W Dolby Audio speakers, a 64.8Wh battery providing up to 2.5 hours of video playback, and Intelligent Environment Adaptation (IEA) for 3-second autofocus and keystone correction. Main pros include its streamlined official streaming app support, impressive sound quality for its size, and highly portable design with a built-in carry handle. However, notable cons include its relatively low brightness in ambient light, a lack of USB-C power delivery charging, and the absence of a built-in adjustable kickstand for angling the projection.
