XGIMI MoGo 4 Laser vs Nebula Mars 3 Air

How they differ in real use

Built from our battery projectors for outdoor movies scoring, each product's published specifications, and verified owner feedback — not hands-on testing.

Both the XGIMI MoGo 4 Laser and the Nebula Mars 3 Air made our Top 5 Battery-Powered Projectors for Outdoor Movies, at #2 (best premium) and #3 (best value). The best picture in a bag-sized body: its RGB triple-laser engine looked brighter and richer than other compact portables to Trusted Reviews and Expert Reviews, and unlike the Mars 3 it ships with Google TV and licensed Netflix at 2.9 lb instead of 10 lb. It ranks second because battery life is its weak point: 92 minutes at maximum brightness for Trusted Reviews, short of the Mars 3's two hours at full output, and its $669 price buys only modestly more measured-class brightness than the $479 LED MoGo 4. The pick for sound and runtime per dollar: its dual 8W Dolby speakers outclass the MoGo 4's 2 x 6W pair, and it lasted 3 hours 23 minutes on battery in The Smart Home Hookup's test, longer than either MoGo. It sits below the MoGo 4 Laser because that runtime comes at only about 128 lumens, and ProjectorCentral measured just 145 lumens in Eco mode, so it needs full darkness. It edges the MoGo 4 on audio and battery endurance even though the MoGo 4 costs about $40 less.

We score battery-powered projectors for outdoor movies on Outdoor Brightness (25%), Battery Runtime (20%), Picture Quality (15%), Built-in Sound (15%), Smart Features (10%) and Value (15%). On that basis the XGIMI MoGo 4 Laser totals 8.1 out of 10 and the Nebula Mars 3 Air 7.9. The widest gap is Outdoor Brightness, where the XGIMI MoGo 4 Laser scores 7.8 against 6.9 for the Nebula Mars 3 Air: measured lumens on battery power and how large an image stays watchable at dusk or with nearby lights. Picture Quality also separates them: 9.4 for the XGIMI MoGo 4 Laser versus 8.2 for the Nebula Mars 3 Air. The Nebula Mars 3 Air claws back ground on Battery Runtime, Built-in Sound and Value.
