Anker Nebula Mars II Pro: Petit portable projector performs proficiently

Anchor Nebula Mars II Pro is surprisingly small Launcher. And I mean little. It is short to hide completely under a six-pack of coke. With built-in Streaming And a good battery for around 3.5 hours of launch, the Mars II Pro is a great companion for a movie night in the backyard or far away grounds. And apart from being a projector, it is also a big Bluetooth speaker.

do not like it

  • Poor brightness and contrast
  • wrong color
  • Limited app store
  • Charging brick required

Video quality will be quite good for many viewers, but it is much more skewed than a similarly priced home projector, with contrast ratios and color accuracy. Compared to other small, battery-powered projectors, the image is very attractive and the speakers are surprisingly powerful.

The main reason to get Mars II Pro is if you want ultra-portable video, especially outside. It is easy to place near a wall or screen and stream some Netflix anywhere within a few minutes. If you plan to use it regularly in the same room, then, you are probably better off with more traditional projectors.

Original specs

  • Original resolution: 1,280×720
  • HDR-compatible: no
  • 4K-compatible: no
  • 3D-compatible: no
  • Lumans Chimera: 500
  • Zoom: None
  • Lens Shift: None
  • Lamp Life (Normal Mode): 30,000 hours

Mars II Pro is smaller than you might think. It will fit easily inside any backpack with plenty of room for water bottle, hoodie, camera etc. The anchor could have been made out of cheap-feel plastic, with a strap to carry, but it has a leather top and is soft. Nice to touch.

There are buttons at the top for all basic functions, but no controls for zoom or focus. This is logical because there is no zoom and the focus is automatic. An integrated slide-open lens cap also turns the projector on and off.

To get a 100-inch image, the Mars II Pro needs to be about 9 feet away from the screen. The resolution is 720p, which is very low for projectors these days and lower than the competition Viewfinder m2, Which is 1080p. The LED lamp is rated 30,000 hours.

The maximum brightness claimed is 500 lumens. I measured about 37 Nits, Which counts about 337 lumens. For comparison, the ViewSonic M2 produces 349 lumens by my measurement, while slightly more expensive, but much less portable, Optoma HD146X Around 1,146 were dismissed.

Anchor claims that the internal 12,500 mAh battery is good for about 3.5 hours of viewing time, and about that for a longer re-charge. If you put it in high brightness mode, it drops to 1.5 hours. If you’re only using the Mars II as a Bluetooth speaker, the anchor claims around 30 hours for audio-only playback.

Although not specifically mentioned by Anchor as a feature, some apps consider the Mars II Pro as a mobile device, so you can actually download the show for its 8GB of internal storage.

Connectivity and convenience

  • HDMI input: 1
  • USB port: 1
  • Audio input and output: 3.5mm output
  • Digital Audio Output: None
  • Wi-Fi: 802.11 a / b / g / n
  • Remote: not backlit

There is an HDMI input, which is enough on such projectors. The USB port lets you stream content from a USB memory stick, or you can charge the device (such as your phone) using the Mars II Pro’s beef battery.

This is for physical connections, other than the power port, which requires a separate power brick. This is a compelling: I’m a hardliner “Everything must be charged via portable USB.” If you want to charge the projector away from home, you will also have to pack the brick.

Mars II Pro runs Android 7.1, which has all the streaming capabilities inside the PJ. So all you have to do is tick your projector on your phone or connect to some available Wi-Fi.

However, or you don’t get the full Google Play store Android tv. Instead, it is Aptoide, a sort of color / curated version of the Play Store. This is a slight obligation with the ViewSonic M2, and it is no better here. There are Netflix, YouTube, Amazon Prime Video, Hulu, Disney Plus and others that you may or may not recognize. There’s HBO Nordic and HBO Go, but no US HBO or not Hbo max. Chromecast is not supported. Overall it is not bad, but you cannot find every service you use.

The remote wafer is thin, but not backlit. That’s fine because you’re probably not going to use it. Instead, there is the Anchor Connect app (Android and iOS), which connects easily and does all the same things. In fact, some apps actually require an app. Controls in the projector’s menu work fine, but it’s a bit clunky in the Netflix app for example. Not a big issue, but it can be smooth.

There are two side-firing 10-watt speakers and a rectangular passive radiator at the front. It does not sound much, but it is quite loud and the sound quality is better than such a small instrument. This is one of the few projectors I’ve actually replaced bottom To achieve a normal listening level.

Image quality comparison

I compared the Mars II Pro to the ViewSonic M2, another portable projector, and the Optoma HD 146X, a traditional plug-in PJ. The M2 is very similar to the anchor, can turn off the battery and also runs apps from the Aptoid store. The Optoma is a very different projector, and a direct competitor in only one sense: price.

I think the Mars II Pro might catch the attention of anyone who is not usually interested in projectors, so Optoma is here as an example of what a similar penny can get you in a non-portable, standard projector . I connected these via a monoprice 1×4 distribution amplifier and viewed them all on a 102-inch 1.0-gain screen.

First up is shine. The M2 and Mars II are remarkably similar. Their light output and contrast ratio are basically the same. In both cases, this amount is “fine.” Considering the size and their ability to operate the battery, around 300 lumens are acceptable. When creating a 100-inch image which is equal to about 37 nits. This is sufficient for a submerged, albeit dim, image. You are moving the better anchor closer, which will create a smaller but brighter image.

Optoma, on the other hand, is much brighter than one. On a screen of the same size I measured 127 nits, which is 5 times brighter than the Mars II. Optoma is very much available at 100-inch. And if you use Optoma’s most color accurate mode, it’s still twice as bright as the other two.

And we definitely need to talk about color. The Mars II Pro has the least accurate colors of any projector I’ve ever reviewed. Blue is the only color 3 primary and 3 secondary colors this is right. Green spreads. Not yellow, but quite greenish-yellow. Magenta is oversaturated and very blue. The result looks like you’ve got the color control ticked up to where it should be. that’s not funny, Actually, And overall it still looks better than the M2, but overall it’s definitely a more speed racer than The Grand Budapest Hotel.

Along with optoma, it is night and day. Or at least Technicolor and Kodachrome. The Optoma itself is not super-accurate, and actually makes mistakes toward the underserved, but its colors look far more natural than those of the anchor.

Unlike Optoma, Mars II does not have extensive picture settings. It has two. You can adjust color temperature: Normal, cool and warm, and even the most accurate (warm) is still very good. You can adjust lamp settings: Standard, Battery and Auto. The standard is its brightest. Battery is low but you get 3+ hours. Auto switches between two other modes depending on whether the projector is plugged in or not. No glare, contrast, tint, etc. One result is that you cannot adjust the contrast to restore details entangled in bright whites.

Contrast Ratio, Such as brightness, an acceptable range is given. I measured an average of 354: 1 in all modes. It sounds short, and it is, but the majority of sub- $ 1,000 projectors are only 2-3x. The high end of that performance range, the BenQ HT2050A is 2,094: 1. The Vuonic at 376: 1 is basically the same as the anchor. Optoma is 568: 1.

The anchor image lacks punch, but not as much as you might think. In fact, because the black level of the anchor is slightly lower than that of the M2, it looks slightly better. The M2 is very slightly brighter, which is not noticeable. This black level is lower than the Optoma, but this projector is so sharp that this edge is not relevant.

Finally we come to the detail. An2 720p has both M2 and HD146X. This is most noticeable on a 100-inch screen if you are close enough to notice individual pixels, which are large enough. If you shrink the image to 60–80 inches, it looks wide enough that it does not look soft.

The conclusion

Honestly, I wasn’t expecting much from Mars II Pro. I have been overwhelmed with most of the battery-powered portable projectors I’ve reviewed. I have also found that companies not known for video gear miss some important things when it comes to projectors. For example, picture quality.

So overall I’m impressed that the anchor got very right with the Mars II Pro. Ok, at least classified on price, size and curve of battery power. It falls short in every performance metric compared to an average home projector, so if you’re looking for something that will never stray too far from the outlet, you’d be better off with a more “traditional” projector. But if you want something portable to watch movies outside, the Mars II Pro has a great design, looks great, is easy to use and has a more attractive image than the visible M2 – all for less money.
