The short answer

XGIMI Halo+ comes out ahead by a narrow margin (4.0 vs 4.3). The gap is mostly about Travelers and apartment dwellers who want a battery-powered backyard projector that they can also slip into a backpack for camping trips, hotel rooms or impromptu movie nights at a friend's place. — read the strengths below before deciding.

BenQ GV31
Ranked #5 in Best Outdoor Projectors
BenQ GV31
2 sources1 derived

BenQ's GV31 has the most interesting form factor here, a rotating ball-in-a-cradle that aims anywhere from a low coffee table up to a 135-degree ceiling angle. The 300 ANSI LED engine is dim and $599 is not budget territory. Set against that: a 5-hour audio/3-hour video battery, a 2.1-channel speaker and a clean Android TV stack with native Netflix, which make it the best 'fun shape' option in the roundup.

Strengths
  • Rotating lens tilts up to 135 degrees, projecting onto walls, ceilings or angled garage doors
  • 5800 mAh battery delivers 3 hours of video playback (5 hours music) per BenQ spec
  • 2.1-channel speaker system with 8W woofer and dual 4W tweeters punches above projector norms
Watch-outs
  • 300 ANSI lumens is the second-dimmest in this guide; outdoor use requires full nightfall
  • Limited HDR support and no Dolby Vision
  • Cylindrical body in cradle is not very stable on uneven yard surfaces without a tripod

3 sources1 derived$499as of Aug 1

Of the compact portables here, XGIMI's Halo+ is the most polished. Projector Central measured 753 ANSI lumens, AndroidPolice scored it 8.5/10, and the Harman Kardon speakers genuinely sing for their size. Battery is the soft spot: real-world runtime sits closer to 90 minutes than the claimed 2 hours, which makes it a one-movie projector unless you tether it to wall power.

Strengths
  • Projector Central measured 753 ANSI lumens, 15 percent brighter than the original Halo and class-leading for its weight
  • Compact 3.5 lb body with auto focus, auto keystone and obstacle avoidance that nails setup in seconds
  • Dual 5 W Harman Kardon speakers deliver the cleanest portable-projector audio in the category
Watch-outs
  • Battery runs closer to 60 to 90 minutes in practice, well under XGIMI's 2-hour claim
  • Older non-Google-TV units lack native Netflix authorization and need a sideload or casting
  • No handle on the chassis despite the carry-everywhere positioning

How they stack up

BenQ GV31

Dimmer than the Anker Nebula Mars 3 Air at 300 vs 399 ANSI lumens but with a more interesting form factor and a stronger 2.1-channel audio system. Substantially dimmer than the Mars 3 or XGIMI Halo+ and not in the same outdoor-cinema league. Brighter than the Samsung Freestyle 2nd Gen at 300 vs 230 lumens and with native Netflix and a battery built in, no $189 accessory required.

XGIMI Halo+

Pound for pound the most polished portable here, but loses to the Anker Nebula Mars 3 on every outdoor-specific axis: 1000 measured lumens vs 753, IPX3 vs no IP rating, and 5-hour battery vs 90-minute real-world runtime. Beats the Samsung Freestyle 2nd Gen on brightness by roughly three times and trades blows with the Mars 3 Air on sound and software while shipping a smarter auto-keystone system.
