Bottom Line

Acer's Projector C20 Series pico projector is for business users who need to give presentations while on the road. Its image quality isn't great, nor is it comfortable to use, but it's small, it can run on battery power, and it's relatively cheap.

The Acer Projector C20 Series is designed for users who require the use of a pico projector while travelling. It's tiny, it can run on battery power and it also possesses a bit of a 'wow factor' (purely because many people aren't used to seeing a projector this small). It's not a completely practical tool, but it can serve a purpose in situations where presentations need to be made to a small group of people and other means of sharing a laptop screen aren't available.

The Acer C20 projector is based on DLP technology and it includes an LED lamp that has a stated brightness of 20 ANSI Lumens and a stated life of 20,000 hours. A screen with a diagonal size of around 50cm can be made from a distance of 1m away and it has a native resolution of 854x480 pixels (these specifications are slightly lower than the HP Notebook Projection Companion). It has a built-in speaker, weighs 166g and it's around 12cm long, 6cm wide and 2cm thick. Connectivity includes a VGA port, Mini HDMI, a microSD card slot and a micro-USB port.

The Acer C20 projector can play content directly off a microSD card, as long as the file format is supported (AVI, MOV, MP4, 3GP, JPEG, BMP, AAC, MP3); a converter is available to make PowerPoint and PDF documents readable. Of course, you don't have to worry about file support or conversions if you just use the device to project a laptop screen. The battery in the C20 lasted just over one hour in our tests.

Because it's so small, you shouldn't expect the Acer C20's image quality to be great — it's far from that. We found it to be very soft on the right side of the image and no amount of physical adjusting or focus control would fix it (nor was there anything to help in the on-screen menu). If you're playing a video, this softness isn't noticeable, but if you're giving a presentation consisting of graphs and words, it will be distracting. The projector works best in a darkened room and from a projection distance of less than 2m.

You can't adjust the angle of the projector without a tripod — it doesn't have built-in legs and it just sits flat on the desk. A tripod is optional. You can adjust the focus via a rotational control on the left side, but it's poorly designed — it's recessed into the body, which makes it difficult to grip, and it's too stiff. The control buttons on the projector are flush and have poor tactility.

It would be good if some of the projector's options weren't options but instead included as standard. We're primarily talking about the tripod and the remote control, and also the adapter for the iPhone. These options would make the Acer Projector C20 Series a very convenient piece of kit. Without them we think the projector is just too awkward to use comfortably.

While the Acer C20 pico projector is aimed at business users, creative computer enthusiasts might also want to consider it for modding projects. Because it's flat, it can be attached to a laptop lid (using double-sided tape would be the easiest method) so that you can easily project onto your ceiling — perfect for watching movies while lying on your back in bed.

That slightly whimsical note aside, the Acer Projector C20 Series has its upsides for business use: it's small and easy to carry, it ships with a battery that can last just over an hour and it has a relatively low price for a pico projector. However, there are also a few downsides: it's not easy to use due to its controls and the lack of height adjustment (the HP Notebook Projection Companion is easier to use), and its image quality is noticeably blurry on the right side. Nevertheless, if you're in the market for a pico projector, then the C20 is worth considering purely because of its comparably low price point.

I have an Acer C20 projector and I have been forced to respond to this article as I feel it has cast more negatives on the product than good.
To be fare not biased tr Acer C20 projector has an assortment if connectivity available even for Pc or laptop. This cable is supplied together with the projector. The picture quality of it is not below average in fact you still get very good quality pictures even at 66" screen size which is the max size.
It has an inbuilt speaker and loud enough for its size and you can connect an external speaker yo it got large audience.
A remote for this is available but not supplied as stated in the article however if you are meeting friends business people on the go all you need is to find a good wall where you can just point your projector and explain or share your input so a remote should not be part of the case.

You can connect an iphone to it etcetc

On image quality I should say it has an adjustment wheel like any project to sharpen the pictures. With an HDMI connection port it's easy to connect any Pc with HDMI and enjoy A 66" monitor Minimum is 15".

So I will say this item is a must have really. In uk it's what managers are given who work in sales or project related fields instead of carrying those heavy duty projectors. Take a vide on your iphone/iPad and instantly watch with friends on 66" screen size

Great size and weight, great looks, good compatibility, internal media player/storage, wow factor
Short battery life, brightness not great, buttons not tactile, fiddily file conversions

It does perform brilliantly once you learn how to use it. It will project comfortably up to 48 inches and more. Movies work best when an external media player is used, be it my ipad or iphone or laptop. Frame rates are consistent and the picture quality is great. It is only 20 lumens, so don't be surprised if you need to turn down the lights and shut the curtains to get a great picture. It has its own speakers, but I would connect it to external speakers for better results indoors and especially outdoors. Playing movies off the internal storage or microsd isn't as straight forward. You have to encode all your movies to one of the supported formats (avi/h.264/mov/mp4) at a max resolution of either 720x576@25fps or 720x480@25fps. For a geek like myself, who occasionally has a bit of time and doesn't mind doing this its fine, for someone less tech-savvy this could be quite tricky. Once the movies are on there, when running them from the internal media player you can start to see the reduction in FPS, although it is definitely still watchable and the picture quality remain great. One gripe is you cannot connect the Acer C20's microSD via the unit itself. You have to use an external MicroSD USB reader - which you have to buy separately.

The Acer C20 looks great, most people either think its a mobile or some kinda Dictaphone. It looks a lot more professional than other makes of a similar size and price. It does runs absolutely silent as it does not have a fan. It gets warm after running an entire movie, but not so hot you think its damaging the components. The buttons look great all flush against the body, however this makes them difficult to feel for in the dark (although the buttons do light up). I did find myself hitting the wrong button an exiting a movie or going into the wrong area of the browser more than once. The addition of the remote control pretty much sorted this out. The focus wheel is manual, but incredibly easy once you get used to it.

I bought the Acer C20 for about 180 quid. I then began adding to it with peripherals which needed to make it a functional portable pico projector for movies - I bought the 3 in 1 Acer c20 tripod/remote/AV adapter kit which cost another £40. I also bought an external speaker for 15 quid and an external 10000 maH battery for 40 quid to keep it going during movies (yes with this size external battery you can charge the acer c20 during function, however, it will not power it enough if it is flat, just prolong the battery life to 3-4 hours. You can power the acer C20 indefinitely if plugged into a wall however). I got a microsd 32gb for £20 and a microsd usb reader for £5. I also bought a logiccase which was another 10quid. So, all in all £310 for a lot of stuff to carry around for a portable movie player. I still think the wow factor is enough to justify this, but if ur happy carrying around a portable dvd player or laptop and think the smaller screen will suffice then that's fine too.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

Anthony Grifoni


For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

Steph Mundell


The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

Andrew Mitsi


The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

Simon Harriott


My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
