The Anker Nebula Mars 3 is a portable, outdoor-focused 1080p LED projector. It's medium-sized, with an integrated carry handle, and features a large 185 Wh battery rated for up to five hours of video playback in Eco mode. It's built with ruggedness in mind, featuring IPX3 water resistance, 0.5 m drop resistance, and 0.7 mm dust resistance. The unit can also act as a power bank, and it has an integrated 40W sound system. It features a full suite of placement helpers, including autofocus, auto keystone, and Screen Fit, making setup quick and easy. The projector runs Android TV 11 with Chromecast built-in; Netflix isn't TV-licensed and must be installed via Nebula's app store (Nebula Play). It's capable of projecting an 80-inch image at about 6.9 ft, up to 200 inches at roughly 17.4 ft (fixed 1.2:1 throw).
Our Verdict
The Anker Mars 3 is a solid choice for those seeking an outdoor projector. It features numerous outdoor capabilities, including IPX3 certification, dust and drop resistance, and a large internal battery that can also serve as a power bank. However, if you're looking for a unit that provides top-notch image quality, it doesn't really cut it. Its brightness is barely mediocre, so you really need to turn off the lights to see the image well, or ensure the sun has set before using it outdoors. Unfortunately, it lacks the necessary contrast to truly impress in dark settings. It's also not bright enough to project vibrant colors, even with its wide color gamut. Finally, it's not very accurate out of the box, so you really need to calibrate it for the best picture quality.
Robust unit with a ton of features geared towards being used outdoors.
Wide color gamut.
Contrast doesn't impress in dark contexts.
Isn't very accurate out of the box.
Relatively dim, so keep the lights off.
The Anker Mars 3 is unremarkable for gaming, even for casual play at 60Hz. It has relatively high input lag at 60Hz; it's fine for slower titles, like turn-based games and visual novels, but anything faster than that isn't optimal. There's no 120Hz support to make the unit more responsive. As for image quality, it's unremarkable overall; its brightness is mediocre, and its contrast doesn't impress in dark contexts. It's also not very accurate out of the box. Considering its portable nature, it's really not a bad-looking image, but it just doesn't excel in any facet for gaming.

No 120Hz mode to make the unit more responsive.
No 4k or 1440p support; downscales signals to 1080p.
Relatively dim, so keep the lights off.
The Anker Mars 3 is just bright enough for relaxed movie nights in a dark room or for watching outdoors after sunset. On a big screen, it looks fairly dim, so you really need to keep other lights off to see the image clearly. Colors are balanced and don't appear washed out, but because the projector is not very bright overall, they still come across as somewhat muted rather than vivid or punchy.
Very uniform brightness.
Only just bright enough for a modest-size image in a dark room or outdoors after sunset.
The brightest Conference mode is heavily green-tinted on our unit.
The Anker Mars 3's contrast limits how cinematic it looks. In a dark room, blacks and letterbox bars appear clearly gray, and darker scenes look flat. With some ambient light, the raised black level is less noticeable, and the image is acceptable for casual use, but it still doesn't offer the deep, rich blacks you would want for serious movie watching.
In a dark room, blacks look clearly gray and darker scenes lack depth.

Popular Projector Comparisons
The Anker Mars 3 is a projector designed for outdoor use, featuring full IPX3 water and dust resistance, as well as drop resistance. It also has a large internal battery that can double as a power bank. If you're primarily looking for a unit to take camping with you, it's a solid choice and is better than other comparable portable units, which are not typically very robust. If you're not necessarily looking to rough up your projector, then other portable products, like the XGIMI Halo+ or the LG CineBeam Q, offer better image quality for a lower price.
Check out our recommendations for the best portable projectors, the best outdoor projectors, and the best home projectors. If you'd prefer to shop for another product in the same price range, look up the best projectors under $1,000 instead.
The XGIMI Halo+ has slightly better image quality than the Anker Nebula Mars 3, but the Anker is a much more robust unit, truly meant to be used outdoors. While the XGIMI is smaller and easier to carry around, it's more fragile, so it's better used indoors. Ultimately, if you value outdoor robustness, the Anker is more attractive, but if you want a small and easy-to-carry-around unit, and you just want to bring it to your friend's house, the XGIMI is better.
The Anker Nebula X1 is far better than the Anker Nebula Mars 3, but they're not in the same price bracket. The Nebula X1 is a heftier unit that doesn't have an integrated battery, but it delivers far better image quality. In turn, the Mars 3 is lighter and has a ton of features meant for the outdoors, but its image quality isn't close to the X1.
The Anker Nebula Mars 3 and the NexiGo TriVision Ultra are two mid-sized projectors with a carry handle, but of the two, the NexiGo is the superior pick. It's far brighter than the Anker, with deeper contrast, so it looks punchier in any room condition. The NexiGo also delivers a sharper image with its pixel shifting technology, while the Anker is limited to 1080p. They're both inaccurate out of the box, with the NexiGo being more so than the Anker, but the former is easier to calibrate. The NexiGo is the superior pick for gamers, too, as its input lag is far lower at 4k @ 60Hz. If you instead game at 1080p, then the Anker's input lag is slightly lower at that resolution, but they're both pretty slow there. Both units have a handle for easy transport and weigh about the same, but the Anker is a tad more portable due to its fully featured smart OS; the NexiGo requires a dongle for apps.
We've independently bought and tested over 75 projectors and published detailed results for each, so you can decide which one to buy. These have all been tested under the same standardized methodology, allowing you to compare them side by side. We still have all these projects in our lab, so we can continually go back and compare them to ensure our reviews are still accurate. All our test methodologies are also public on our website, so you can validate the results yourself.
