Wirecutter's best outdoor projector and a PCMag Editors' Choice: the brightest battery-powered model Wirecutter tested, with a 40 W speaker that holds up outdoors and splash and drop resistance. It weighs 9.9 lb, Netflix has to be sideloaded on its Android TV, and owners say the interface gets sluggish.

Top complaints

  • Android TV is sluggish; Netflix needs a workaround

    Wirecutter notes you must sideload Netflix. A top Amazon reviewer says that after a year the built-in Android TV stays sluggish despite updates, and others recommend a streaming stick. Amazon's summary mentions a buggy interface.

  • Heavy, and connection quirks

    At 9.9 lb it needs a sturdy tripod (Wirecutter, PCMag). It has no USB video input (Wirecutter). PCMag had trouble connecting some 1080p sources. A 1-star Amazon review says copy-protected movies downloaded to a phone wouldn't play while camping.

  • Value questioned; distracting battery light

    Amazon's summary says opinions on value are mixed, with some calling it comparable to non-portable models at the price. PCMag found the ring of battery LEDs on the handle distracting when sitting behind it, and it has no optical zoom.

What owners love

  • Brightest battery projector tested

    Wirecutter measured over 800 lumens max and over 600 in the best-looking mode, enough to go past 100 inches. It had the longest battery in its test: about 2 hours at full brightness and 4 hours 45 minutes in Eco mode.

  • Sound that works outdoors

    Wirecutter calls the speaker the real difference-maker outdoors. PCMag says the 40 W three-way speaker fills a large family room. Amazon owners say it fills the room.

  • Built for the outdoors

    IPX3 water resistance, drop resistance onto cement from half a meter, a lens door, a lantern and phone charging (PCMag, Wirecutter). PCMag saw almost no rainbow artifacts.

Good for
  • Backyard and campsite movie nights
  • A big image without an outlet (about 2 hours at full brightness)
  • Sound loud enough outdoors without a speaker

What experts say

  • Wirecutter (NYT): Top pick for outdoor use (updated 2026-10-05): brightest and longest-lasting battery projector tested, with the best speaker; bulky, and no USB video ports.
  • PCMag: 4.0/5 Editors' Choice, its first for an outdoor projector. Good picture and audio and rugged, but no optical zoom and a distracting battery light. MSRP at review was $1,049.99.

If that catch is a deal-breaker

Highly ranked projectors whose biggest complaint is something else.

#1 in projectorsHisense C2 Ultra

Wirecutter's top living-room pick and a PCMag Editors' Choice: very bright (about 2,200 lumens measured), with top-tier HDR and a real subwoofer. It costs about $1,900 to $2,500, weighs 13.9 lb, the stand isn't optional, and about 1 in 7 Amazon ratings are 1 or 2 stars.

Its catch: bulky stand you must use#2 in projectorsHisense M2 Pro

A smaller, cheaper take on the C2 Ultra that Wirecutter and CNET both pick as their budget 4K choice: sharp, high-contrast, with good sound for its size. It's less than half as bright (about 800 to 950 lumens measured), it has a single HDMI port, and Wirecutter found video ads on the home screen.

Its catch: much dimmer than the c2 ultra#4 in projectorsBenQ HT2060

CNET's best 1080p projector: some of the most accurate color it has measured, good contrast, a long-life LED and rare lens shift for the price. It's only average in brightness (985 lumens), it isn't 4K, and there's no built-in streaming at all.

Its catch: only average brightness
