This means it doesn’t need to sit as far from a wall or projector screen to produce a large image. It weighs just 1.8kg, similar to some laptops, and has a short throw lens. It does not have a battery and you’ll need a rucksack to take it over to a friend’s house, but it is a very handy projector to take between rooms in your own home.

The Asus F1 stretches the limits of what we might call a “portable projector”.

If that's all you require, it does the job. But it is compact, relatively affordable, sounds reasonable, has a three-hour battery life and does a fair job displaying SD-quality movies. No-one is likely to be bowled over by this projector. Getting a perfectly in-focus picture requires some finger gymnastics.Īnd, no surprise here, the Viewsonic M1+ needs a fairly dark room to achieve an acceptable image.

It has a flimsy wheel, and the M1+ tends to change focus slightly as soon as your take your finger off the control. The Viewsonic M1+’s focusing is fiddly too. This is a DVD-quality projector, not an HD one. Faces look smooth rather than blocky, although naturally there’s limited fine detail. Text looks terrible, but we are pleasantly surprised by how invisible the pixel structure is even when projecting at 100 inches. That's hardly surprising as resolution is very low at 854x480 pixels. Image quality is mixed, and not up to the traditional standards of TVs and projectors. The sound may only be that of mediocre budget bluetooth speaker, but it’s much better than that of most pint-size projectors.
SMALL PROJECTOR MOVIE
While it sounds harsh and brash at maximum volume, the dual Harman Kardon speakers deliver enough volume for a movie night if you keep things sensible. 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.
SMALL PROJECTOR 480P
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.
SMALL PROJECTOR ANDROID
It has a battery that lasts up to four hours and Android rather than a basic menu system.
SMALL PROJECTOR PORTABLE
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.
