Verdict

The Anker Nebula Cosmos is a smart 1080p home cinema projector featuring 900 ANSI lumens of brightness and a maximum projection size of 120 inches. Key characteristics include native Full HD resolution with HDR10 support, autofocus, and dual 10W speakers delivering 360-degree sound via Dolby Digital Plus. Its main pros are the user-friendly Android TV 9.0 interface with over 3,600 apps, a portable 2kg design with a tripod mount, and consistent stable performance. However, notable cons include the lack of a built-in battery for true outdoor portability, limited black levels that struggle in bright rooms, and the absence of a 3.5mm audio jack for analogue sound output.
