Portable projector offers 400 lumens on battery power

Nov 21, 2014 — by Eric Brown 2,712 views

[Updated Dec 8] — We initially reported that AAXA’s “M4” projector, with 400 lumens brightness on battery, runs Android. However, unlike the company’s Android-based “LED Pico” projector, the M4 runs proprietary software.

We originally, erroneously thought AAXA’s new battery-powered “M4” projector was controlled by an embedded Android OS. However, we were informed today that unlike the company’s “LED Android Pico Projector,” the M4 runs “proprietary software designed by AAXA.”

does run Android

AAXA Technologies offers a wide variety of projection systems, including the recent Android-based LED Android Pico Projector, which sells for $499. The LED Pico received a “Good” rating in November from PCMag, which lauded the 550-lumen projector for its image quality, but dinged it for its poor video quality.


The new, $599 M4 Mobile LED Projector is similarly portable and has the additional advantage of being battery powered, but runs homespun software rather than Android. The M4’s 28W Lithium-ion battery can last for up to 90 minutes in “eco brightness” mode, says AAXA.

The M4 is brighter than the LED Pico when plugged in, giving you 800 lumens compared to 550, whereas on batteries it tops out at 400 lumens. That’s still bright enough to make the M4 the “world’s brightest battery powered projector,” according to the company.

The M4 uses a combination of triple-RGB LED technology along with a Texas Instruments DLP Imager. The technology can drive projections of up to 150 inches, according to AAXA’s most prominent claims, and 200 inches according to some other AAXA notations. The M4 delivers 1280 x 800-pixel native resolution, with a maximum of 1920 x 1080, as well as a 2,000:1 contrast ratio and a 20,000-hour lifespan, says AAXA.

Here’s a rough comparison of AXXA’s M4 projector with some Android-based projection systems that we’ve covered over the last two years :

  • Sprint LivePro ($450) — DLP; 100 lumens; 1,000:1 contrast; 1280 x 800 native (up to 1920 x 1080); 20,000 hours; up to 120 inches
  • TouchPico ($449) — 80 lumens; 854 x 480; up to 80 inches
  • Promate LumiTab ($666) — DLP; 35 lumens; 854×480; 20,000 hours; up to 100 inches

AAXA M4 details

One thing all these products, including the AAXA LED Pico, have that the M4 lacks is Internet access. Although the device includes a built-in media player for decoding video, there’s no WiFi — content must be stored on the built-in 4GB of flash, a microSD card, or a USB 2.0 drive. Other display sources include a DTV tuner, as well as HDMI, VGA, and Composite A/V inputs.

The 8.3 x 5.3 x 3.1 in. projector weighs 2.44 pounds. No embedded processor details were listed, but the M4 is said to ship with 1GB of RAM. The M4 also includes an audio jack, and a pair of 2W speakers.

A control keypad is built into the top of the unit, and there’s optional remote. There’s no mention of an Android or iOS control app, but the device is said to be compatible with Nexus and HTC Android devices using a SlimPort adapter, as well as with Samsung Galaxy and Note Android devices using an MHL adapter. You can plug in iPhones and iPads using an Apple Digital AV adapter, says AAXA.
