Nothing beats a night at the movies - especially when you have a 4K projector to watch the latest blockbuster on. And here that comes courtesy of Nebula, makers of the Mars 3 (#MF396) and Mars 3 Air (#MF402), both of which teamed 1080p Full HD resolution with lashings of portability.

The Nebula Cosmos 4K SE continues the family look with a boxy rounded corner design, complete with integrated carry handle and a smattering of ports on its rear: 2x HDMI 2.1 ports (one with eARC for connection to a soundbar), plus 1x USB-A and an 3.5mm aux output, although unlike the Mars 3 and Mars 3 Air, there's no built-in battery for true watchanywhere movie viewing. Instead it has a built-in power supply, which you'll need to connect to the mains, limiting its versatility a little. The Cosmos 4K SE is also significantly chunkier and heavier than the Mars 3 and Mars 3 Air, weighing in at 4.5kg and measuring 263x165x265mm. The tiny Mars 3 Air, by contrast, measures just 178x122x133mm and weighs 1.7kg.

This is a heavyweight projector in more ways than one- and not only thanks to its 4K Ultra HD resolution
