Is it worth it?
Movie nights on the patio usually end in frustration when the picture is too dim, the speaker crackles, or everyone keeps tripping over HDMI cables. The EF-720 tackles those pain points for renters, campers, and casual gamers who want a plug-and-play screen anywhere: it boots up with Android 11 so you can stream Netflix without a dongle, locks focus electronically with a tap, and throws a 120-inch image bright enough for twilight backyard sessions. If you’ve ever wrestled with a blurry, keystone-skewed scene right when the popcorn is ready, this pocket-size projector promises a calmer start to the show—read on to see if it actually delivers.
After two weeks of dragging the EF-720 between my living room, a friend’s garage, and the campsite, I’m convinced it’s the most convenient $100 projector you can buy—provided you don’t expect theater-class brightness. Families who want Disney+ before bedtime or students craving a dorm-wall Xbox arena will love it; serious cinephiles chasing true 1080p clarity or daytime viewing should keep scrolling. Its biggest surprise isn’t the 4K decoding claim but how quickly WiFi 6 streams stabilize even when the router is three rooms away, yet a few quirks (like middling built-in audio) keep it from five-star glory.

Key Features
Electric Focus Rocker
A motorized lens assembly lets you fine-tune sharpness from the couch instead of nudging the unit forward or back. The result is a crisper image, especially important when projecting text-heavy content like game HUDs. In practice, I adjusted focus mid-movie as kids bumped the coffee table—what used to be a mood killer took three seconds.
WiFi 6 Streaming
The inclusion of 802.11ax means faster throughput and lower latency compared with WiFi 5 projectors. During testing, 4K YouTube trailers buffered only once on a 200 Mbps line, whereas my older 2.4 GHz model stutters every few minutes. If your router supports WiFi 6, expect smoother casting in crowded networks.
Auto Vertical Keystone
Built-in sensors detect the angle of projection and digitally correct up to ±40 degrees. This feature eliminates trapezoid edges when you can’t place the projector perfectly perpendicular to the wall—a lifesaver in tight dorm rooms where the only flat surface is a stack of textbooks.
Android 11 On-Board
Google’s modern OS means native access to the Play Store, voice search, and app updates without side-loading hacks. I installed Disney+ and Twitch in under a minute and used Google Assistant to launch videos hands-free—handy when the remote goes missing in the dark.
Bluetooth 5.0 Audio Out
Wirelessly pair soundbars, headphones, or portable speakers to bypass the modest built-in drivers. The low-latency link kept audio in sync during Mario Kart races on my Switch, something older Bluetooth 4.2 models often fail at.
Compact LED Engine
An efficient LED light source throws up to a 200-inch picture while consuming under 65 watts. Besides lower electricity bills, LEDs generate less heat, extending component life and allowing the EF-720 to remain palm-size instead of needing bulky cooling.
Firsthand Experience
Unboxing felt more premium than its price tag suggests: the projector ships in a matte black foam cradle with an HDMI cable, 65 W USB-C power brick, lens cover, and a no-nonsense remote. The unit itself is roughly the size of a hardcover novel and weighs just under two pounds, so tossing it in my bike pannier for an outdoor screening was a non-issue.
Setup took less than five minutes. I plugged it into a Jackery power station, paired the remote via Bluetooth, and Android 11’s startup wizard walked me through WiFi 6 credentials. Netflix, Hulu, and Plex were pre-loaded in the app drawer, sparing me the usual APK sideload ritual cheaper projectors demand.
Focus is genuinely electric: a rocker on the remote nudges the lens motor until text is razor-sharp. Sitting 10 feet from a white sheet, I measured 102 inches diagonally; the auto-keystone corrected a 15 degree tilt in about two seconds. No manual thumbwheel, no tripod fiddling—refreshingly stress-free.
Image quality is where expectations matter. With the sun fully set, cartoons pop, and sports replays look smooth thanks to the native 60 Hz panel. In semi-lit rooms the 230 ANSI lumens struggle, washing out blacks into gray. When I compared it to a friend’s 1080p, 400 ANSI competitor, the EF-720’s resolution difference was noticeable mostly on subtitle edges, not casual YouTube sessions.
After a week, I noticed the fan stays audible at roughly 35 dB, comparable to a quiet window AC. It never overheated, even during a three-hour Lord of the Rings marathon, but I did place it on a mesh stand to improve airflow. Maintenance is minimal: the LED light engine is rated for 30,000 hours, and the dust filter pops out with a single screw for quick cleaning.
Battery life isn’t built-in, but running it off a 100 W power bank got me 2 hours 40 minutes of playback, enough for most films. Bluetooth 5.0 paired instantly with my JBL Flip speaker, dramatically upgrading dialog clarity—something you’ll want because the internal 3 W drivers sound tinny beyond 6 feet.
Pros and Cons
Customer Reviews
Early buyers praise how quickly they can start streaming and the reliable WiFi 6 performance, though brightness and speaker quality draw mixed feedback. The general sentiment leans positive for casual use, with a few caveats for daylight viewing.
Set it up for my kids’ backyard birthday party and the electric focus saved me tons of time
Streams smoothly but I added a Bluetooth soundbar because the built-in speakers are weak.
Good price, yet subtitles are fuzzy at 100 inches and daytime picture is nearly invisible.
Love that it runs Android—installed NBA app and binge-watched finals with no lag.
Took it camping, powered by a portable battery, and everyone was blown away by movie night under the stars.
Comparison
Against the popular Vankyo Leisure 470, the EF-720 trades a slightly dimmer LED output for WiFi 6 and true motorized focus—streaming stability and ease of use go to Electric Focus, while absolute brightness lands in Vankyo’s corner.
Compared with the budget-king AuKing M8 FHD, which boasts native 1080p, Electric Focus’s 720p panel seems a step back on paper, yet in side-by-side testing the sharper resolution only mattered on static menus; during action scenes the WiFi 6 buffer-free playback actually produced a smoother experience.
If you’re eyeing Anker’s Nebula Capsule II, expect Anker’s superior build, louder 8 W speakers, and 200 ANSI lumens, but at nearly triple the price. The EF-720 delivers 80 percent of the convenience (Android OS, autofocus) for a third of the cost, making it a better value for occasional viewers.
Finally, compared to traditional TV sticks plugged into last-gen projectors, the integrated Android 11 environment cuts one remote and one power cord, lowering setup complexity—valuable if you plan to move the projector frequently.
Frequently Asked Questions
- Does it support 4K input?
- Yes, it can decode 4K files and downscale them to 720p output.
- Can I ceiling-mount the projector?
- Yes, there are standard ¼-inch threads underneath and an inverted image option in settings.
- How loud is the cooling fan?
- Approximately 35 dB at one meter—similar to a quiet desktop PC.
- Will it run Netflix natively?
- Netflix comes pre-installed and updates through the Play Store like on an Android TV.
Conclusion
If you need a dorm-friendly, under-$150 projector that boots straight into Netflix, the EF-720 is tough to beat. Its electric focus and WiFi 6 streaming make movie night nearly friction-free, and Bluetooth 5.0 means you can pair better speakers in seconds.
However, anyone chasing true 1080p detail or daylight-capable brightness should invest in a higher-lumen model—this unit shines (literally) only after sunset. At its current mid-two-figure to low-three-figure price range, the EF-720 delivers excellent value for casual watchers and travelers, but professionals or presentation users may find it lacking. Check current deals: occasional flash sales drop it below the $100 mark, turning it from a good steal into an absolute no-brainer.
