Style: Cosmos 4K SE (1800 ANSI)
This is a big upgrade from my 12 year old epson projector (a business model for presentations mostly). Plenty bright for inside viewing with some natural light, but it really shines at night. Very quiet fan compared with my old projector and the built in speakers are clear and plenty loud enough for our 400 square foot room. I don't notice the cooling fan at all when the volume is high. I even prefer to use the built-in speakers for outside viewing, as long as the audience is mostly within 30 feet of the projector. The android system works well enough; compared with my roku ultra, it would feel a little slow if I were using it daily for streaming or jumping from app to app or youtube video to youtube video, but since I only use it occasionally for movie nights, I don't mind at all. I love the automatic keystone and autofocus. I'm normally just throwing it up on an off-white wall between sconce lights (no screen) and it usually knows to frame the video between the lights and squares it up nicely even when positioning the projector to the side of the room. I can't compare it with other comparable projectors, but I know I have not been disappointed at all after 8 months of weekly use.

Style: Cosmos 4K SE (1800 ANSI)
So I’ve wanted a projector for awhile now and before I ever buy anything of value I try to do as much research as possible so I know I’m getting the best product for my money. I came across nebula projectors and instantly wanted one and was about to purchase the Mars 3 to use mainly outdoors for movies by the pool. I’m glad I waited and did a bit more research bc in the time that I took looking into other projectors, nebula came out and announced this one. I decided to IMPATIENTLY wait until the release date of this model and bought it early in the morning on the day of its release. The specs are amazing and I thought better in almost every way when compared to the cosmos 4k laser projector, except for the ANSI lumens on this one is a little less bright, however it is way more than adequate. I love the simplicity and the Google play operating system that has all of the apps that you could ever want or need. It’s simple and fast to use and make having this projector that much better. The sound quality is better than I expected and you can watch things and not feel like you need to hook up surround sound or a sound bar to enjoy a movie. However when you do it’s as simple as connecting it via Bluetooth and having an even more move theatre like experience. Portability is a breeze with it’s convenient carrying handle and it makes setting it up anyway super fast and simple. I suggest a tripod or a projector stand for good stability and adjustability. When it comes to the picture quality it is superior to my 70” tv, which we ended up taking down and putting up a 120” fixed screen by elite screens. It is truly a 4k image and looks amazing especially at night and if you are watching an animated movie with the kids. Football has also been an absolute blast to watch and makes viewing the games that much more immersive and makes you feel like your right there on the field with the players. I don’t have any issues watching this during the day either, yes I do shit the blinds and still have ambient light coming through but it doesn’t take away from the image quality and color all that much. In fact it might make it better since you don’t get a glare on the screen like you do with TVs. Watching poolside has also been a blast, lucky for my my house color is a light grey on a stucco wall. Even though I bought a 120” yard master outdoor screen by elite screens, I have no issue throwing the image just up on the side of my house and having it be super clear. It’s been very fun changing how we watch movies and the reason I say it’s literally been life changing is bc we spend more time having movie nights and making smores etc. the kids really look forward to it, rather than being on their phones and tablets in separate rooms they all wanna be together picking out and watching their favorite movies on the new big screen. You really do feel like you get the movie theater experience in the comfort of your own home. I highly recommend this projector to anyone looking for a very good projector that gives you far more in value for its price than many other projectors out there. You can easily compare it to ones that cost twice as much. The hybrid use of both laser and LED is genius to me bc you get the best of both worlds and like previously stated the image quality and color are practically flawless. The pictures and video that I posted don’t even do it justice as the image and color look even better in person. The images/video of football was also just projected on my wall before I had a dedicated screen up and that just goes to show how good the quality is. Auto keystone and focus is super easy to use and makes setting up a breeze in just a matter of a few seconds. If you’re in the fence about purchasing this projector just go ahead and do it and thank yourself later. I am buying another one so that I can permanently mount it in the Family room and then have one for outdoors by the pool. I promise you will not regret buying this. I hope this helps even in the smallest way with helping you make that decision.

Review for the new 4K SE model. This is my first and I have a feeling not last projector. After being an LG OLED addict for the past decade it was finally time to try a projector. I paired this with a 100in projector screen (Lopbast and Elite Screens) in our bedroom where we had no room to hang a larger TV. With the auto focus and keystone correction I was able to easily get a full 100in image even with the projector very off center in the corner of my room and the image looks perfect. Was planning to mount the projector on the wall or ceiling but no need to do so. The image quality is absolutely perfect in a dark room and has this vibrant quality to it that I don't see on my LG OLED. I was honestly blown away, I knew that projectors have drastically increased in performance (and lower cost) the past few years but this blew away my expectations. With the blackout blinds closed during the day it is great as well. With indirect sun light and no blinds it is perfectly fine. With direct sunlight of course that is where it can't hold up to an OLED but still viewable. The software is great with Google TV, app selection is fantastic, casting works great. All of the settings are integrated nicely with a one touch keystone/focus adjustment on the remote. Remote is super nice, light and backlit. And finally the audio, it is better than I expected. I have a 5.4.2 setup in main theater room so I'm pretty picky. No I won't be watching Atmos action movies without a sound upgrade. But thus far after watching a few TV shows and some classic movies it is perfectly fine and really appreciated that they included such a nice set of speakers with nice bass. I also plan to use this projector outside and in other portable locations and the speakers will be great in those scenarios. I most likely will add a Bluetooth sound bar at some point. Overall highly impressed and I'm very happy that I've tried my first (of many) projectors!

Update 11/26/2025 I'm warning you now DO NOT buy this!! It is a taking time bomb that would be riddled with performance issues sooner than you think. Don't let the nice picture fool you!! YOU HAVE BEEN WARNED !!! 😞 So sad that I have to update this review to a one-star. I no longer recommend this product. Way too many performance issues while viewing videos. Constantly having to recalibrate, refocus,recenter after each use. I've had times where it didn't even want to turn on after a cold start. Audio cutting in and out in the middle of a TV show. I've had cheaper projectors perform much better than this. I don't understand how something can be so expensive, but yet operates worse than a cheap $100 projector. I actually really loved this projector I love the picture I love the Dolby vision bright colors. However it's riddled with possible performance issues later on down the road. I would recommend you look elsewhere first before purchasing this. I want to also say that I treat my property well so I'm not abusive towards it I turn it off at night and I keep it off until I actually need to use it. I make sure that the room its in is cool. But it just wasn't enough for it! Even going through the settings is a nightmare because it's constantly freezing. No matter how good a picture is if the performance is going to be an issue then it's pretty much pointless. Please put a stronger chip or something inside the thing for it to run more smoothly it's costing us way too much money for you guys to cheap out on the processor. And whatever else you guys cheaped out on.. this is why I try to stick with known brands like LG for example. Why doesn't this projector have 5 stars? 4.3 is way too low for an amazing projector. I mean it's doing more than I even expected!! Get it while it's on sale!! $899 vs $1,300 ?? There's no debate get it while you can at such an outrageously low price! There's so much I can talk about, but the picture is much brighter than I thought. I have it set up in my room mounted on my ceiling and when I tell you it's as bright as my TV maybe even brighter! It can definitely replace a TV. I have an 100'' screen plastered on my wall! That screen was only $25. I always hear you have to have at least $1,000 screen, but to be honest it is amazing I can't imagine spending $1,000 on a piece of fabric... Grab this projector and grab inexpensive screen not too cheap but definitely not $1,000 because it's projector is enough especially if it's used indoors in a dark room. I have blackout curtains so there you have it. If the projectors begins to suck I will update this review lol

This is my first projector and I have no previous experience. I've had good TVs and monitors and I consider this a great projector. Even better for the price I paid on Black Friday. Very easy to install, lightweight to transport (4 kg). I'm using it on my living room wall and the image is incredible. The Anker sound is very good, too. I recommend it. The case is also very well built and practical for taking on trips.

It seems so many reviews of Anker Nebula projectors are sponsored, and only focus on the positives. This review is not sponsored. This is now my third PJ from the Anker Nebula series. First, I had a Mars II, then upgraded to the Mars 3, and now the 4K SE. The Mars 3 I had purchased last year, and it had some very interesting features. Namely, that unit is entirely portable (battery powered). Picture quality and brightness were "good", particularly for a portable projector. What really hampered these previous projectors was the built-in software, which was based on AndroidTV 10. That's a very old version of Android... It didn't support Netflix, and worst of all, in use the projector was SO SLOW to use. Even with the Mars 3 I purchased last year, just moving around the user interface with the remote to find things to watch was an awful experience. I am happy to report that the Nebula 4K SE, which runs GoogleTV, is a whole different ballgame. The projector can finally run Netflix, and the user interface is sufficiently snappy and doesn't get in the way. It feels modern and is a massive improvement over the other Nebula Projectors. I would NEVER purchase one with their AndroidTV-based OS again, and nor should you. It's unfortunate Anker has this strange division in their product lines... As for the rest of the projector... the image quality is lovely. I have been using projectors since the early 2000s, and it amazes me how great they have become in such small, portable packages. The built-in speakers, while not a home theater system, sound like a decent quality portable Bluetooth speaker, which in other words, is good enough for their intended use. Brightness is great. I did end up disabling motion correction as I personally can't stand that on any display I use. The power supply for this projector is integrated into the unit itself. This is great, as the Mars 3 came with an absolutely comically large power brick. So to just have a simply power cord to connect is nice. I give up battery power with this unit, but I am OK with that. So overall, I am quite happy to be swapping out the Mars 3 with the 4K SE.

This projector has many of the features of a larger and more expensive projector. The picture is amazingly sharp and clear. It self adjusts focus when you turn it on and has keystone correction features to fit your screen application. I have a dedicated Stewart firehawk screen but the projector will make a color adjustment automatically if you decide to project the image on a painted wall or use a white sheet. It is portable with a carrying handle so it can easily be moved anywhere. The speakers in the projector are adequate but I have mine connected to a surround sound system in a dedicated theater room. This projector is a great value for the money and setup is quick and easy. I would recommend this projector for the diy home theater enthusiast.

After trying a bunch of projectors , I finally settled for this mighty one. The brightness and the picture quality of this projector is stunning and I am totally impressed what it delivers at this price point. I do not have the fancy screen and I just projected it on my dry wall and it's like watching a movie on a movie theatre screen. Imagine how the quality will be when using a good projector screen! It has Google TV which is a huge plus and i love installing various apps that are readily available to install and watch. The noise is very low and the set up is super easy! It has Dolby Vision which is a big deal to me ! This is a marvelous projector that's portable and bright enough. LOVE IT!
