Excellent performances
The device is really well built, solid and easy to use.
The image, even if not 4k, looks bright and crisp; another positive point is the noise from the fan which I expected to be louder and instead is surprisingly moderate.
Google TV software is very usable and is like having a smart tv in the projector.
Streaming from iOS device is good as well the connection to extrernal BT speakers or headsets.
It can be used also in moderately lit environments (maybe not in daylight)
Indeed a recommended purchase.
This is THE projecto
The Anker Nebula Mars 3 Air is a portable masterpiece compared to all those other crap chinese projectors for 100-400 GBP. Ive went through around 6 if not 7. Save a little bit up and buy this piece of machinery. It has impressive performance when it comes to the OS lag and speed (better than my smart TV), Its sleek design makes it easy to take anywhere, perfect for movie nights and presentations on the go. The 400 ANSI lumens brightness and 1080p resolution ensure a bright and clear picture, whether you’re watching movies, playing games, or giving presentations. (When a playstation or xbox is detected, the projector turns into gaming mode providing a very smooth gameplay, VERY low (I’d say immediate, as good as a tv) input lag. And the HDR is really noticeable during the night, little less so during the day due to the lack of lumens to handle HDR)
Connectivity options: HDMI, USB, and wireless casting via AirPlay and Miracast, offering flexibility to connect a variety of devices seamlessly. The built-in dual 5W speakers produce rich and immersive sound, enhancing the overall viewing experience without the need for external speakers. Especially the PS5 (sounds phenomenal).
While the Mars 3 Air’s battery life may be limited to around 3 hours, it’s a small trade-off for its portability. The built-in fan can be audible during quiet scenes, but it’s a minor inconvenience considering the projector’s overall performance.
Only downside I could think of is the focus, it seems to struggle to keep the whole image focused when further away (around 7 feet). I’m unsure if it’s a software bug or the camera within the projector which may be low quality which causes the struggle.
If you have a PS5 though, this is definitely your Go-to if you’re on a 500GBP budget. I managed to enable surround-sound with dolby atmos audio, HDR10 and 4k video output on YouTube and netflix (the projector doesn’t support 4k but higher bitrate video really improves image clarity making the image even better). So for those who have surround sound and want a projector, the projector in the settings has a dolby digital plus setting and you can tweak the bass and treble to your preferences, but if you have surround sound and a PS5, connect it to the projector and… congrats you have a cinema at home
Excellent portable projecto
I was very undecided on this projector as it was my first dive in to the projector world, I had actually ordered a smaller cheaper (same brand) projector to begin with and was very underwhelmed and the item was quickly returned and replaced with the Mars 3, wow what a difference, once setup I really cannot fault this projector, google TV is far better than the android operating system that 90% of other projectors appear to be using, the auto keystone makes it a breeze to setup in different rooms/walls etc and the sound amazed me to be honest, I did not expect it to be half as good as it actually is, don’t get me wrong it’s not a full on cinematic experience but superior to most standard TV speakers and actually creates quite an immersive experience when the projector is behind you.
I regularly use this item and the family love cinema night, although the image will go to 150″ I’m regularly projecting at 120″ which seems to be the sweet spot. I’m also using for work meetings to do presentations, it’s so easily portable (buy a case though), brilliant all rounder highly recommend.
Very impressed with this product, well worth the money.
TV-quality but portable.
I haven’t always relied on a TV as my lifestyle is quite on the move but I love watching movies and streaming. I’m just not always in my living room. This is where a projector becomes my best friend. It’s almost like I can carry a TV wherever I am, without the fuss of cables and fragile screens.
This mini projector is a beast. The setup was super easy, user friendly, and took a couple of minutes for it to get up and running after an update. The auto focus was a bit fiddly and I preferred to manually do it, but I’ve had said issues elsewhere so I wasn’t at all surprised. Picture quality is crisp, bright and just as impressive as a high-end TV. The sound quality is great too. I was surprised at the amount of bass I was able to get even without having a speaker connected.
Battery life of 2.5 hours is slightly optimistic. Perhaps feasible when on eco mode which lowers the picture quality slightly, but this hasn’t been a deal breaker for me.
It’s portability lives up to the name and it’s possibly one of the smallest projectors I’ve seen with this picture quality. Definitely worth the money and I’d be happy to recommend.
Very clea
This projector is the beat one I have had yet, I’ve used multiple and this one by far is the clearest and best overall one I’ve owned. Before this one I used the smaller version of this one and that was good enough, to be able to try this one and use is incredible. It’s well built, very easy to use and sync upto my devices to display the image. Highly recommend
Fantastic Projecto
I have quite a bit of experience with projectors, I currently own a 4k Laser and a regular 1080p projector. This despite being a quarter of the size of the 1080p one is much, much better picture quality. I know it’s easy to think “well, 1080p is 1080p” but that’s just not the case as there’s always a lot of variables that create a better (or worse) picture.
The set up of this device is pretty simple, I didn’t open the manual and it was very much straight forward. It does want you to have Google TV and to be honest, while you can use it without it, it is much better that you do have an account (it’s free and you’ll need it for all the apps like Netflix, iPlayer etc). On first boot it requires a small update of around 800-900MB, however, this took a very long time despite having fast internet. I think it took at least 10 minutes, which did originally concern me on how fast the Wi-fi is but I believe it was just unpacking and installing files as once done everything was fast and snappy.
I love the fact it’s portable and it truly lives up to the name. It is battery powered and can be carried around and just placed where you want it unplugged. Battery isn’t very long, you’re looking at around 2 and a half hours but that should be more than enough for a film, a great device to take with you camping!
The sound is fantastic for its size, there’s a lot of bass and you can really feel it, it makes for a fantastic cinematic experience. I have no complaints about the sound at all.
The projection automatically levels itself as well which is brilliant. If I had to nit-pick however, setting the screen is incredibly easy but I found increasing the size is slow, a small little notch at each button press. However, there’s possibly an easier way to do it as I like to test things without the manual to see how user intuitive it is.
I have seen some complaints asking how it works, it works exactly as a projector works. I don’t think it’s fair to take it out on the device because people don’t understand it. It’s not a TV, you need to project something! However, despite this not being a TV it’s actually closer to one than a lot of others with the smart features, being able to use apps like Netflix, Prime, Youtube etc right out of the box. Again, you’ll need a (free) google account which takes a couple of minutes. You have an HDMI and USB port so you can connect other devices to it like a Switch, console etc.
Being a projector it does require a darker room, although even with the curtains open on a grey day the picture was very good.
Personally, I think this is an absolute fantastic piece of kit, it offers you a lot in a very small size.
At 549.99 it’s not a cheap price if you don’t know what you’re getting, but I think the price is actually very reasonable and offers everything you’d need from a projector and more! Giving you everything a standard one will while being portable and battery powered. There’s also currently a 100 voucher giving a whopping discount making this a fantastic purchase and in my humble opinion, one of the best Tech devices of 2023.
This was a little bit of a stab in the dark as I was looking for a small portable projector for the bedrooms and the mars 3 air had just come out and had no real reviews yet. I was first tempted by the Samsung Freestyle 2, but a lot of reviewers noted that for its price (~700) it wasn’t that good a projector. IIRC it only goes up to 240 lumens. But it had good apps and connectivity, so it was hard to find something with a similar feature set but cheaper. The Mars 3 was generally recommended as an alternative, but that’s a similar price point to the Freestyle for a bulkier, brighter protector that’s better for outdoor use, which I don’t care about that much.
That’s where the Mars 3 Air came in – at 450 it’s much cheaper than the freestyle, almost twice as bright, and has excellent connectivity and app support, with even native Netflix, which the more expensive Mars did not have.
Some things to watch out for – first time set up is a bit slow, confusing and clunky. Google Home setup via the app is pretty okay, but it took a *long* time to download and install firmware updates. Once it was up and running, it still behaved weirdly, e.g. I could not access the settings menu, or sign in to YouTube, or download new apps at all at first. The trick seems to have been to reboot it several more times. Once fully set up it all works as expected.
The auto keystone features and auto focus in my experience aren’t great – they’re a good starting point, but at least in my space, I usually do need to go in and manually adjust them. If this is the case for you, I would recommend turning off auto keystone and auto focus on startup and after movement, so you don’t have to recalibrate every time you nudge it or turn it off.
Overall though I think it’s a really good deal for the price – responsive UI, very solid brightness and colours, great sound. Connectivity and apps all work fantastically, and having Netflix natively on the device is great! You can also Chromecast easily from a laptop or phone. Expect a bit of faff during first time setup, but after that it’s a really solid device!
Just amazing
This item is just amazing. I have had a projector made by nebula before and it was outstanding the one I had was a one for home it was wired and not portable. As soon as I seen this one I knew I needed it. This is the Nebula Anker Mars 3 Air 1080 mini projector and I cannot tell you enough how amazing this is. At the time of purchase this was 559 but this is well worth the price.
This item is portable and can be taken anywhere you want it to be taken, it is great for your bedroom, for camping, sleepovers it is endless on what you can do with this projector.It is small yet powerful it comes with a sturdy durable handle on the top of it so it is easy for you to carry it without dropping it or damaging it. It is super easy to set up and the instructions are very clear to read. It is so bright the image is as good as a high quality TV if not better than a TV due to it’s 400 lumens. You can even watch it when it is light outside it is that good the quality is crystal clear and colours are outstanding. It has a 2.5 Hr play back which is more than enough time for a movie or if you want to listen to music this is upto 8 hours play time. It comes with Dolby audio so the audio is intense and clear it is so good honestly the list could go on with how amazing this is. It comes with multiple extras such as google, netflix the list is endless
Overall this is an outstanding projector I cannot wait to take this camping this will be so fun. It is amazing quality and I think the price is very reasonable I am so happy with it. If you can afford one I highly recommend it.
Absolutely phenomenal
I wasn’t expecting to be as wowed as I was with this.
As I said in the video, I was sitting around for ages while it installed updates, and even though I chose basic TV, it almost gives no choice but to use Google TV. Which in hindsight is probably best as it gives access to apps that don’t require another device to play them, like YouTube.
This really is a quality item. I can only say, even on the Eco mode, it’s like watching an LCD screen.
If there’s a downside, the manual is not very helpful. The plus side, if I can figure this out, you probably can.
Fantastic portable projector with Netflix built i
I’m a bit of a projector nerd, having owned several different makes and models over the years. I’ve owned all the Nebula Capsule models but, apart from the Capsule 3, I’ve never found them to be bright enough and, of course, none except the 3 had fhd.
I purchased the Mars 3 (do not confuse this with the Mars 3 Air that this review is covering) and loved it because of its brightness, full HD and the sound. But it is a hulking brute of a projector and still had no native support for Netflix.
Soooo.. what about the Mars 3 Air? Well, I love this too. Its small, light and totally portable. At 400 lumens it is bright enough for me to get a 120ins picture on my wall in darkness or very low lighting conditions and the image look incredible In full HD. The sound coming from dual 8w speakers really surprised me. It was loud and had plenty of deepness to it which I didn’t expect without a subwoofer. As usual, the battery claims of 2.5hrs runtime are perhaps a little optimistic and rely upon the battery being set to eco mode which reduces the brightness somewhat and I’d have preferred USB-C charging so a power bank could be added but, all in all, this is a great addition to the Anker projector factory and my favourite one yet.
Sincrement,
Que ce soit la qualit de l’image ou la qualit du son les deux sont magnifiques !
Qui plus est il est trs silencieux
Mais bon je vous laisse juger par vous mme regarder la vido
Bravo cette marque !
