Best portable projectors: compact, mini projectors 2021

Included in this guide:

Best portable projector Buying Guide: Welcome to What Hi-Fi?'s round-up of the best portable projectors you can buy in 2021.

Portable projectors offer very different features and considerations compared to traditional machines. They're comparatively cheap. They come with built-in speakers, so there's no need for an AVR or external sound devices. They often have apps on board as well as storage options so that they can supply the content too. And, if you're really lucky, they'll have a battery which means you can take them with you wherever you go.

Think of them more like the Swiss Army Knife of the cinema world. This is why portable and mini projectors are a great choice for many. There's no need to replace your TV. Just pull out your portable when you want to go big. You can even take them around to friends’ houses for movie nights.

What's more, installing a portable projector is no more complicated than finding a flat surface or even a sheet hung in the garden and pointing the thing at it (though a dedicated screen is so much better). Some have kick-stands to help and almost all have tripod attachments.

A few years ago, these mini projectors were still hard to recommend despite their convenience. 'Pico' projectors had dim light sources that couldn't do justice to colours or contrast, even in a darkened room.

Today’s portable projectors benefit from improvements to LED and laser light tech. And that means a bigger, brighter picture and no more worrying about having to replace the lamp after a year or so. Traditional projector lamps tend to last 2000-3000 hours. LEDs last tens of thousands.

There’s no magic, brand-new tech in the lower-end of the portable world, of course. If a projector fits in the palm of your hand, it will not be particularly bright nor kick out top notch detail. No micro projector works well during the day or with the curtains open either.

This is one reason why our best portable projector round-up includes almost all flavours in this category. There’s a pick so small you could fit it in some large coat pockets.

The newer “lunchbox” style projector is a better fit for many, though. They offer a decent compromise of portability and performance, and will likely have the better software extras, as these are real lifestyle tech buys.

Right at the top of the tree are projectors that blur the divide between normal and portable designs. They are only slightly smaller than some normal home projectors but have built-in speakers and other convenient features such as short-throw lenses. This means the projector does not have to be as far from the screen to create a large, cinematic image, and they can be stowed away in the cupboard again once you're done with your viewing.

Got all that? If that sounds like the kind of convenience and entertainment you're looking for, then read on for our best portable projectors of 2021 guide.

1. LG CineBeam HU80KSW

This all-in-one, do-it-all portable projector does it all well.

Resolution: 4K (with HDR)
Type: Laser
Brightness: 2500 lumens
Throw ratio: 1.3 - 1.56
Focus: Manual
Zoom: Manual
Keystone correction: Auto
Dimensions: 47 x 17 x 17cm
Weight: 6.5Kg
Reasons to buy
+Everything in one compact box+Impressive 4K HDR picture
Reasons to avoid
-Detail and motion could be better-No battery

It's not what you'd call 'mini' but the LG CineBeam has an integrated handle for easy carrying and is small enough to be easily hidden away in a cupboard when not in use.

That's especially impressive when you consider it's more or less an entire home cinema system: a 4K HDR picture, stereo sound, an array of smart sources, all in a unit you can carry like a holdall and set up wherever and whenever you might choose. Even the power cable is wound up inside the base, so there is really nothing you have to plug in if you don’t want to.

That’s the great beauty of the CineBeam: its versatility and intuitive simplicity. As long as you have a clean wall or ceiling upon which to throw a picture, you can have it up and running in a matter of minutes each time you use it.

Picture performance is strong: impressively crisp and detailed, with decent depth and natural hues. It is bright enough without being garish, vibrant enough to combat leaked sunlight. And it sounds surprisingly good by the standards of integrated speakers, too.

The only downside is the price, but if you want the best, you're going to have to pay for it. Besides, you'll find lots of more affordable options below.

2. Epson EF-12

A smart, small and seriously punchy projector

Resolution: 1080p HDR
Type: 3LCD
Speakers: 2 x 5W
Brightness: 1000 lumens
Inputs: HDMI (x2), USB
Audio out: Bluetooth, 3.5mm
Smart platform: Yes
Battery: No
Storage: 10GB
Dimensions (hwd): 14‎ x 18 x 18cm
Weight: 2.1kg
Reasons to buy
+Tidy build+Strong black depth and dark detail+Decent sound system
Reasons to avoid
-Colours lack complexity-Mains power only-Some key missing apps

Epson's 3LCD projection system is squished down here and housed in a very tidy 14‎ x 18 x 18cm, 2.1kg box. While not quite as serious for brightness and picture quality as the company's more traditional home cinema machines, it still has a way with contrast and shading that's beyond the reach of most portable projectors.

What's more, its sound system is streets ahead of most. It's a 2 x 5W set-up that's been tuned by Yamaha. It's remarkably expressive with just enough precision to hold its own even in scenes with heavy action.

There's no iPlayer, Netflix or All 4 apps on the smart platform and we'd like Epson to have fitted an internal battery too but these are relatively minor gripes and nothing that neither a media streamer nor an extension cable can't solve. Definitely one for your shortlist.

3. Anker Nebula Solar Portable

The best Nebula portable projector so far

Resolution: 1080p HDR
Type: DLP
Speakers: 2 x 3W
Lamp: 400 lumens
Inputs: HDMI, USB
Audio-out: Bluetooth
Smart platform: Android TV OS
Battery: Yes
Storage: 8GB
Dimensions (hwd): 6 x 19 x 19cm
Weight: 1.4kg
Reasons to buy
+Vivid but balanced picture+Great portable size and features+Decent spread of sound
Reasons to avoid
-Sound system lacks impact-Blacks could be deeper

This is Anker's best Nebula projector to date and also a very, very good portable in its own right. Feature-wise, it's got almost everything one could need in an outdoor/portable projector. There's an excellent smart platform, a three-hour battery life, a good degree of brightness and plenty of source material options.

What tops it off, though, is some really rather impressive picture quality. There are brighter machines out there but, for this price, there's a great blend of both punch and subtlety to the image. In the right setting, it's just the ticket.

The onboard speakers are a touch weedy but the quality and spread of sound from them is good.

Do be warned that the app platform is missing a few of the UK catch-up services, iPlayer included, but otherwise, this feels like one of the best projectors out there for taking on your travels. It's small, convenient and very well appointed.

4. Asus F1

Projects a cinematic image in dark rooms.

Resolution: 1920 x 1080
Type: DLP
Brightness: 1200 lumens
Throw ratio: 0.8:1
Focus: Motorised AF
Zoom: Digital
Keystone correction: +/- 30 degrees
Dimensions: 25 x 75 x 21cm
Weight: 1.8Kg
Reasons to buy
+Decent DLP image+Solid light output+Engaging picture
Reasons to avoid
-No battery-Not the most portable design

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

It weighs just 1.8kg, similar to some laptops, and has a short throw lens. This means it doesn’t need to sit as far from a wall or projector screen to produce a large image. A 1.4m distance gets you 80-inch movies.

It’s also less likely to get damaged when moved about as it uses an LED light array rather than a traditional lamp.

At this size you get much closer to the image quality of a traditional home projector. Its resolution is Full HD, 1920 x 1080 pixels, and the 1200 lumen brightness doesn’t need anything like the light-blocking preparation of a smaller model.

If you want to use a projector in the day time, the significantly brighter Epson EF100 is a better bet. But with the Asus F1 you get a much more cinematic image in a dark room. Colours have real DLP punch and the black level is more than respectable. 

We’re not in the same class as JVC’s D-ILA range here, of course, but if you can project onto a grey wall or a white screen with black border, you’re looking at very enjoyable home cinema experience.

Unlike many more traditional projectors, the Asus F1 does not have lens shift or optical lens zoom, just digital zoom and keystone correction. Both limit picture quality so it’s a good idea to take out a tape measure to check it will suit your living room. You need some patience for the menu system too, as it can be very slow to respond.

5. Nebula Mars 2

A battery-powered, truly portable package that's fun to use.

Resolution: 1280 x 720
Brightness: 300 lumens
Throw ratio: 1.2:1
Focus: Motorised AF
Zoom: No
Keystone correction: Auto +/-40 degrees
Dimensions: 18 x 12 x 14cm
Weight: 1.8Kg
Reasons to buy
+Fun to use+Truly portable
Reasons to avoid
-Not Full HD-Basic colour reproduction

The Nebula Mars 2 sits in a portable projector sweet spot. 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. It’s cute.

This is easily the most fun portable projector in this group too. It has a battery that lasts up to four hours and Android rather than a basic menu system. The front-end is customised for use with the supplied remote, and has a dedicated app store rather than Google Play. But you can still download Netflix, BBC iPlayer and countless other apps to run direct from the Mars 2.

That includes games, but don’t get your hopes up. Most don’t run perfectly, although you can pair your phone and use its touchscreen like a laptop trackpad.

Image quality is respectable too. In a room with closed curtains and no lights switched on, the Mars 2 can produce a watchable image on a 100-inch screen. The projector dims significantly on battery power, but head to the settings menu and you can turn this off. It will simply last closer to two hours than the claimed four.

There’s no worrying about focus either as it has motorised autofocus. 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. Its 720p resolution offers far better image detail than a basic 480p model and is a huge upgrade for gaming in particular. And you don’t need to look close to notice that.

The bad parts? Colour reproduction is not particularly good. It lacks finesse and vibrancy, and only minor image controls are available. And while larger than some, the Nebula Mars 2 still needs a partially light-controlled room to produce sufficient image contrast.

6. Viewsonic M1+

A tiny projector with built-in Harman Kardon speakers.

Resolution: 854 x 480
Brightness: 300 lumens
Throw ratio: 1.2:1
Focus: Manual dial
Zoom: No
Keystone correction: Veryical +/-40 degrees
Dimensions: 14.5 x 12.6 x 4cm
Reasons to buy
+Reasonable image in dim light+Speaker goes surprisingly loud
Reasons to avoid
-Low resolution and brightness-Poor focus control

Mini projectors don’t get much more convenient than the Viewsonic M1+. It’s tiny, and only weighs as much as four phones stacked in a pile. And it does come with wi-fi, a MicroSD card slot, plus USB Type-A and USB Type-C connectors.

The stand makes projecting an image from slanted surface, or onto angled walls, a cinch. Its speaker is the real surprise, though. 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. The sound may only be that of mediocre budget bluetooth speaker, but it’s much better than that of most pint-size projectors.

Image quality is mixed, and not up to the traditional standards of TVs and projectors. That's hardly surprising as resolution is very low at 854x480 pixels. Text looks terrible, but we are pleasantly surprised by how invisible the pixel structure is even when projecting at 100 inches. Faces look smooth rather than blocky, although naturally there’s limited fine detail. This is a DVD-quality projector, not an HD one.

The Viewsonic M1+’s focusing is fiddly too. It has a flimsy wheel, and the M1+ tends to change focus slightly as soon as your take your finger off the control. Getting a perfectly in-focus picture requires some finger gymnastics.

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