Open-vent projectors suck dust onto the internal lens within months, leaving permanent black spots on your movie. CineGo 4K Pro uses an IP5X fully sealed optical engine outputting 850 ANSI lumens and 15,000:1 contrast for punchy colors from 50 to 200 inches.
Leave the extension cord inside. The built-in 15,000mAh battery powers a complete feature film or football game on the patio, while dual 10W neodymium drivers deliver deep cinematic bass without needing an external soundbar.
Bump the table? CineGo’s front Time-of-Flight laser sensor refocuses and squares the frame instantaneously without interrupting your movie, and automatically scales around wall light switches or picture frames.

Dual 10W drivers fill an entire backyard with clear dialogue and deep bass.
Sealed light engine keeps outdoor pollen, campfire smoke, and house dust off the internal glass.

Yes! 850 ANSI lumens is more than double the brightness of standard 300-ANSI battery projectors, delivering vivid colors from dusk onward and in rooms with ambient light.
Yes. Every CineGo 4K Pro ships with a foldable 100-inch anti-crease projection screen (with mounting hooks), a tabletop tripod, and a padded shoulder carry bag at no extra charge.
Absolutely. You can download movies onto a USB flash drive, download offline shows on your phone/laptop and connect via HDMI, or use your phone’s hotspot.
The dual 10W chamber speakers easily fill a 20×20-foot backyard patio for 10+ people—and you can also pair external Bluetooth speakers or use CineGo itself as an 8-hour Bluetooth boombox.
Most projectors pull cooling air directly across the internal LCD panel, causing unremovable black dust blobs after a few outdoor uses. Our IP5X sealed engine keeps dust out permanently.
You are covered by our 30-day 100% money-back guarantee with free return shipping if it doesn’t exceed your expectations.

★★★★★Our Saturday night poolside movies are the talk of the cul-de-sac
Hung the free 100-inch screen on our pergola, set the CineGo on the patio table with zero extension cords, and watched Top Gun: Maverick while floating in the pool. The 850 ANSI brightness and 20W speakers blew everyone away.

★★★★★Finally a sealed lens that doesn’t get dust spots!
I threw away two previous outdoor projectors because bugs and dust got inside the lens and left black blotches on the screen. The IP5X sealed engine on the Cosari is still spotless after 12 backyard nights.

★★★★★Bought 2—one for our RV, one for our basement rec room
With the 2-pack savings, we keep one permanently in our Airstream and one in the kids’ playroom. Way better than mounting a fragile glass TV in an RV.
