Battery minis, lifestyle cubes and bright living-room portables compared on official manufacturer specifications. Brightness is scored only with an ISO 21118 or ANSI label; Hisense's XR10 6,000 ANSI “peak” figure and Optoma Photon Go's “HK” lumens are quoted and not scored. Weight is scored in pounds, and a missing battery figure is treated as the category minimum.

XGIMI HORIZON 20 Max
Score 6.1/10 · Check price
Why it wins: 5,700 ISO-lumen 4K lifestyle projector with Dolby Vision, optical zoom and lens shift. Top brightness (iso or ansi) in this comparison (5700 lm).
"Not listed" means the manufacturer page we used does not publish that figure. Prices show "Check price" until a retailer feed provides a current price.
Buying guide: how to choose the right portable projector
How bright a portable needs to be
A 200–500 ISO or ANSI lumen mini is typically a dusk-to-dark or camping projector. Lifestyle models in the 1,000–4,000 range are aimed at living rooms. We only score ISO or ANSI labels; a “peak,” “LED lumens” or “HK” number can look larger than the scored set and still not enter the rank.
Battery, weight and speakers
A listed battery runtime only helps if you actually need to unplug. Models with no battery are kept in this category when the maker positions them as lifestyle or portable sets, and their missing battery figure scores at the category minimum. Weight is converted to pounds when the maker lists kilograms, and speaker-channel sums are labelled computed.
Lifestyle 4K versus pocket 1080p
Horizon, Titan-class cousins, Nebula X1 and Dangbei MP1 Max are living-room lifestyle projectors, not pocket projectors. Capsule, MoGo, Elfin, GV and Page One models are the genuinely small set. The ranking uses the same criteria for both, so a heavy bright 4K set and a light battery mini can trade blows on different criteria.
Lamp, laser and mounting safety
A projector beam is bright enough to be uncomfortable or harmful if you look into the lens, and laser models in particular should be treated with the same caution you would give any intense light source. Follow the maker's installation manual for clearance, ventilation and, on ultra-short-throw sets, any proximity or child-safety sensors. Ceiling mounts and shelves need to be rated for the published weight of the projector plus a margin; have a qualified installer do the work if you are hanging a heavy home-theater or UST cabinet. Replace lamps only with the type the maker specifies, and let the unit cool before you move or service it.
How this ranking is calculated
Score = weighted average of normalised specs, out of 10. Full method
Brightness (ISO or ANSI)White brightness the maker labels ISO 21118 or ANSI. Peak and unlabelled or “HK” figures are quoted, not scored. Missing values take the category minimum. Scale: 100 → 5700 lm.
22%
Resolution classFour classes (computed) from the maker's resolution label: native 4K, 4K UHD including pixel-shift, 1080p, and HD / WXGA / WVGA. Scale: 1 → 4.
16%
Light-source lifeThe longest light-source life the maker lists. Missing values take the category minimum.
8%
Built-in speakersSpeaker output the maker lists. Channel sums are labelled computed. Missing values take the category minimum.
10%
WeightPublished weight, in pounds (kilogram figures are converted and labelled computed). Lighter scores higher. Missing values take the category minimum.
16%
Battery lifeBattery runtime the maker lists, converted to minutes where needed. Missing values, including models with no battery, take the category minimum.
12%
HDRYes when the maker lists HDR10, HLG, HDR10+ and/or Dolby Vision. Unstated counts as no.

Smart OS or streamingYes when the maker lists a smart OS or built-in streaming. Unstated counts as no.
Why do some Nebula pages cite soundcore.com instead of seenebula.com?
The us.seenebula.com product URLs we tried returned a storefront 404. The official soundcore.com Nebula product pages loaded and are the source for those specifications.
Why isn't the Hisense XR10's 6,000-lumen figure scored?
Hisense's official US page lists “6,000 ANSI lumens peak brightness.” We quote that wording and leave peak figures out of the brightness score. Several other XR10 fields (weight, throw, light life, speaker watts) were not in a readable table when we checked.
Which portable models did you leave out?
We did not rank the Epson EF-21, because we could not find a usable official specification table or PDF. Samsung The Freestyle US and UK pages we fetched had no readable spec table. Hisense M2 Pro and LG PU615U pages also had no usable table. Dangbei Atom, Freedo, N2 Mini, N3 Max and DBOX02 models are omitted because the official pages we captured did not publish enough scored figures (ISO or ANSI brightness, weight, life or speakers) to compare fairly.
