Verdict

The Anker Nebula Mars 3 is a rugged, outdoor-focused portable projector featuring native 1080p resolution and a bright 1,000 ANSI Lumens LED light source capable of projecting images up to 200 inches. Its core strength lies in its 185Wh battery, which provides up to 5 hours of playtime in Eco mode and functions as a high-capacity power bank for charging external devices via USB-C and USB-A ports. Designed for durability, it boasts IPX3 water resistance, 0.5-meter drop resistance, and a built-in lens cover, handle, and camping light. Additional key features include powerful 40W 3-way speakers with Dolby Digital Plus, Android TV 11 for streaming, and intelligent environment adaptation for near-instant autofocus and keystone correction. However, notable drawbacks include its relatively large and heavy 4.6kg build compared to other portables, the lack of native Netflix support requiring a workaround, and distracting white battery indicator lights on the handle during viewing.
