Its speaker is the real surprise, though. The stand makes projecting an image from slanted surface, or onto angled walls, a cinch. And it does come with wi-fi, a MicroSD card slot, plus USB Type-A and USB Type-C connectors.

It’s tiny, and only weighs as much as four phones stacked in a pile. Mini projectors don’t get much more convenient than the Viewsonic M1+. And while larger than some, the Nebula Mars 2 still needs a partially light-controlled room to produce sufficient image contrast. It lacks finesse and vibrancy, and only minor image controls are available. The bad parts? Colour reproduction is not particularly good. And you don’t need to look close to notice that. Its 720p resolution offers far better image detail than a basic 480p model and is a huge upgrade for gaming in particular. Sharpness is less than perfect and there’s some disparity to the sharpness across the image, but you’ll only notice if you look carefully. There’s no worrying about focus either as it has motorised autofocus. It will simply last closer to two hours than the claimed four. The projector dims significantly on battery power, but head to the settings menu and you can turn this off. In a room with closed curtains and no lights switched on, the Mars 2 can produce a watchable image on a 100-inch screen. Most don’t run perfectly, although you can pair your phone and use its touchscreen like a laptop trackpad. That includes games, but don’t get your hopes up. But you can still download Netflix, BBC iPlayer and countless other apps to run direct from the Mars 2. The front-end is customised for use with the supplied remote, and has a dedicated app store rather than Google Play. It has a battery that lasts up to four hours and Android rather than a basic menu system.

This is easily the most fun portable projector in this group too.

It is far from palm-sized, but has a synthetic leather carry strap and a shape similar to the Bang & Olufsen BeoLit 15 “lunchbox” wireless speaker. The Nebula Mars 2 sits in a portable projector sweet spot.
