  • Licensed Google TV with Netflix
  • 2x8 W stereo speakers

What it does well

  • Licensed Google TV with Netflix built in
  • 400 ANSI lumens is bright for a battery projector

What it gives up

  • Two hours of battery is one film, not two

The two lists above are read off manufacturer specifications and published measurements, not from owner reports. Where owner discussion has been collected it appears separately below, so the two are never mistaken for each other.

What owners say

Owners comparing the battery projectors in this family land in a consistent place: this is the one to buy unless you specifically need longer runtime. Picture and sound quality are described as close to the larger, more expensive sibling, the remote here is backlit where the larger one's is not, and the price difference is real.

Against the smaller pocket projectors in the same family the gap is larger and the direction is clear. Owners who have run them side by side describe this as noticeably brighter with better colour, and say the pocket models lose brightness and colour quickly once they are more than about a metre from the wall.

The honest limit both owners and sceptics agree on is light. Owners report that even the brighter sibling at 1,000 lumens looked about the same as this one with some natural light in the room — which is another way of saying that neither is a daytime projector, and that curtains do more for the picture than the lumen difference does.

What owners like

  • Owners report it is noticeably brighter and better on colour than the pocket-sized battery projectors in the same family, and describe the difference as obvious side by side
  • Netflix is built in and licensed, which owners name as a specific reason to pick it over cheaper battery projectors that need sideloading
  • The remote is backlit, which owners note the larger and more expensive sibling model does not have
  • Owners report picture and sound quality are close to the larger, pricier model in the same line, so the cheaper one is usually the sensible buy

Common complaints

  • It needs a dark room — owners report that even the brighter sibling looked no better with some daylight coming in, so the extra lumens do not buy daytime use
  • Battery life is shorter than the larger sibling, and owners report plugging in the charger more often as a result
  • Owners point out it will not accept a 4K signal where the larger model will, even though neither displays 4K

Questions owners ask about the Anker Nebula Mars 3 Air

Should I get this or the larger model in the same family?

Owners say this one unless runtime matters. Picture and sound are close, the remote here is backlit where the larger one's is not, and the main differences are battery life and the ability to accept a 4K signal — which neither displays natively.

How much brighter is it than the pocket-sized battery projectors?

Roughly double, and owners who have compared them directly describe the difference as obvious. They also report the pocket models lose brightness and colour quickly beyond about a metre from the wall, which is a limitation this model does not share to the same degree.

Can I use it in daylight?

No. Owners are consistent that the room has to be dark for a good picture, and report that even the brighter sibling at 1,000 lumens looked about the same once natural light was in the room.

Does Netflix work?

Yes — licensed Google TV with Netflix built in, which owners name as a specific advantage over cheaper battery projectors that require sideloading or a separate stick.

Can I connect it to a PA or external speakers?

Owners planning outdoor use ask this regularly. It has Bluetooth for wireless speakers, and the HDMI output chain can feed a receiver if one is in the signal path. The built-in 16 W stereo is good enough that several owners outdoors never bothered.
