Sensors at the front of the projector can detect its angle and distance from the screen, giving fast and accurate autofocus and auto keystone correction. Impressively, the projector can also detect a screen and resize its image to fit automatically. It’s a decent smart projector in its own right, too, with vivid colours and loud speakers. Contrast could be better and the Netflix workaround is a little fiddly. Design Using the projector inside, I could fill an 80-inch screen during the day, provided I shut the curtains. Even then, the Anker Nebula Mars 3 was better suited to bright and colourful content, as moodier films and TV shows were a bit harder to see until light levels dropped. You can perfect the image projected from the Nebula Mars 3 with keystone correction, autofocus and screen fit tools. AI environment adaption automatically adjusts brightness to suit the conditions, and an AI image Adjust tool reduces noise and improves contrast. An integrated stand allows you to adjust the projection angle easily, and a built-in 40W sound system supports Dolby Audio. The Nebula projector runs on Android TV 11.0, allowing you to stream content from various apps. You can also wirelessly cast content via Chromecast and control the gadget with Google Assistant voice commands. Ports on the projector include USB-C, USB-A and HDMI, and the device is Wi-Fi compatible. Firstly, setup is really easy. It takes you through connecting the projector to your home Wi-Fi network and setting it up with your Google account, and you can either do this manually or use the ‘set up my device wizard’ on an Android phone. After that, it’s just a matter of installing apps from the Google Play store and adding your credentials – anything stored with your account should just pass through. Then you’re ready to point the projector at a screen.

While you’re better off lining the picture up as best you can (straight on avoids the need for any digital corrections), the auto routines at least mean that the Anker Nebula Mars 3 can compensate for any issues fast. Mars 3 has passed the 0.5 m standard cement floor drop test, which ensures that the device functions properly after accidental drops from a height of up to 0.5 m.

To return faulty items see our Returning Faulty Items policy. Inside the box, there's a 1,920-by-1,080-pixel DLP chip and an LED light source rated at 25,000 hours in full-power mode. Also inside are the already-mentioned sound system and the battery. The sound system takes advantage of a 40-watt, three-way speaker (meaning there are separate drivers, or components, for high, midrange, and low frequencies) plus Dolby Digital Plus. The battery is rated at 2 hours in full-power mode for video, 5 hours in Eco mode, and 15 hours for audio only when serving as a Bluetooth speaker. The projector can also serve as a power bank to charge other devices. The Mars 3 menus offer four predefined modes with no adjustment options, plus one Picture Custom mode with settings for Contrast, Saturation, Sharpness, Color Temperature, Wall Color, and Gamma. The brightest mode, Bright, adds a green tint, but is in the range that most people will consider tolerable if they need the extra brightness. The others are all more than acceptable by most people's standards. Picture Custom takes on the setting of whatever mode you were just using before switching to it, so whatever your preferred choice among the predefined settings is, be sure you're in that mode before switching to Picture Custom.

With great speakers like this, you’ll want to get the most use out of them as possible. That’s why the Bluetooth audio mode is a killer feature for a battery-powered projector like this. Just put the projector into Bluetooth speaker mode and you can start playing your music from your phone, using the speakers from the projector. As I mentioned before, the fan noise was previously an issue with Nebular projectors, as they are active even in Bluetooth speaker mode. But with the Mars 3, they are quiet enough that I can actually use the Bluetooth mode without hearing the fan. What looks to be a sturdy carrying handle on its top also has basic controls (volume, sound, a directional selection pad) built-in for easy thumb maneuvering, and the portability features continue with the addition of an ambient LED camping light, and the ability to use it as a power bank for charging phones and other devices. Three 40-watt Dolby Audio-equipped speakers also mean that you don’t have to lug a speaker into the woods with you, and should you just want to use the Mars 3 for listening to music over Bluetooth, that 185Wh battery will let you do it for up to 15 hours on a charge.

I’m almost as pleased with the Mars 3’s meaty audio. With three speakers and 40W to play with, it’s powerful enough for a decent movie night, and clear enough to carry dialogue and do justice to the score and effects. At higher volumes things do start to get a little rough and boisterous, and you can’t expect convincing stereo or surround effects from such a compact source, but it’s good enough that you can do without separate speakers or a soundbar. I have tested the projector a few times. Although the auto keystone feature worked most of the times, only once it completed failed me during a camping trip. My theory is that it was because it was complete darkness and it was not able to figure out the edges of the projector screen edges. But when it is able to detect the edges of the screen, it works flawlessly.

Enjoy Up to 5 Hours of Playtime Anywhere: Our exclusive RoamPower️ technology supports a 185Wh capacity, which lets you use Mars 3 as a power bank to charge smart devices, enjoy 5 hours of movies, and listen to your favorite tunes for 15 hours. Outside, the projector works best in darkness, although it can be used from dusk at slightly smaller screen sizes.In addition to the speakers, you can use Bluetooth headphones for audio. For wired headphones or speakers, you can use the 3.5mm audio output. And finally, I tested the USB-C port for audio out and found that it is indeed compatible with your USB-C headphones. The STANDARD mode is brighter but cooler (slight bluish whites). Colors produced by the BRIGHT setting come across very well, with color accuracy starting to suffer in darker scenes. In all user modes, the highlights are blown out in some cases. To fix this, you can reduce the contrast settings and increase the brightness.

It does NOT do full indirect sunlight -- do not but this projector if you want to watch this on a sunny day. Beyond the physical setup, the Mars 3 offers automatic keystone adjustments and digital zoom. It also can automatically fit its image to match the size of whatever you're using for a screen. In my tests, all of these features worked as promised. The auto focus also worked nicely, but sometimes required rerunning it a second or third time to get sharp focus. Still, as with any projector, you might want to ignore these automatic adjustment features, since they lower image brightness and can introduce artifacts. There’s a motion compensation option, too. While I’m not a massive fan of this technology, on a large screen and with DLP tech, a little bit of compensation can help smooth out the image. PerformanceThe reason I didn't pull the trigger on any of those other projectors was primarily SOUND, most of them sporting a 10w speaker -- intended to be hooked up to a separate sound system. One of the most important things to get right with a portable projector is giving it enough battery life to watch a standard-length movie on one charge. Anker claims a 2-hour battery life in standard mode and up to 5 hours in eco mode. During my testing, I found these claims to be accurate, with both modes exceeding their claimed battery life by a few minutes. The best experience for me was the AI brightness mode, which let me stream a 3-hour video podcast on YouTube, and I still had about 40% battery left. There are four different picture modes to choose from, the most accurate picture modes appear MOVIE and CUSTOM. We did most of our viewing in MOVIE mode since it delivered good color reproduction, whether the projector's light output was set to either full brightness or eco mode. When the CUSTOM mode is selected, you can adjust the contrast, saturation, sharpness, color temperature, and gamma. Aside from the BenQ GS50 it seems as though most portable smart projectors aren’t particularly well built to take being carried around. The Anker Nebula Mars 3 is different: it’s robust and built for the great outdoors. Anker says it is looking into the problem to see if it's a compatibility issue that a future firmware upgrade can fix. In the meantime, if you run into it, the easy workaround is to set the video source to 4K or 720p. Even the Bodnar meter worked using 4K/60Hz input, reporting a 26.6-millisecond input lag, which is suitable for casual gaming. (Credit: Anker)

It is clearly designed to be weather/outdoor resistant -- but do not expect to get this thing wet. There is a built in lens cover that also serves as the power switch. An a decent remote.

Lots of LEDs

As is increasingly common for native 1080p projectors, the Mars 3 negotiates a 4K (3,840-by-2,160-pixel) connection by default when possible, so it effectively behaves like a 4K projector with soft focus. In my tests, however, it had problems connecting with some sources that were set to 1080p. When connecting to a Verizon Fios box, for example, it usually connected at 1080p, but once negotiated a 720p connection instead. It also repeatedly failed to connect with the Bodnar meter I use for testing input lag at 1080p, reporting "no signal." Since the Nebula Mars 3 is meant for outdoor use, your experience with color accuracy will fluctuate quite a bit based on the surface the image is projected on. Your image will also look different if you’re watching content at dusk or in total darkness. With that in mind, these tests were run in a totally dark environment using a matte white screen. Anker has an AI image mode, automatically adjusting brightness based on the ambient conditions. It’s useful to have, as means that you don’t have to adjust brightness manually as it starts to get darker.
