But there's a need for some truly mobile projectors. We're not just talking US, here, but internationally. Projectors can come in handy on field trips, but there are also places where electric isn't reliable - think rural/2nd/3rd world, where a battery powered projector may be the only best choice.
If that's the case, the hands down solution is our winner in this category, the AAXA P700!
If it wasn't for the AAXA P700's internal battery capability, it would still be a very respectable LED pocket projector, a worthy competitor for both the NEC and Optoma models addressed in this report.

But it is the battery ability, and the ability to carry several small light batteries for extra runtime that makes the P700 stand out. It's a good time to mention here, that the P700 will run up to 70 minutes on one battery.
More than a decade ago, when I sold my large online dealership, Our company had sold well more than 1000 of the earliest pocket projectors (20, then 50 lumens) to missionary organizations who sent them around the world to teach poor students in rural areas. Missionaries, school teachers, government entities, are all potential users of a projector like the P700. There really is a significantly large market, even if relatively small compared to traditional projectors. And as I previously mentioned, there's potential for a projector like this on a field trip, or simply to provide one to special teachers, and other support staff that travel from not only classroom to classroom, but school to school.
So, what, besides battery power makes the AAXA P700 a worthy contender? Most everything.
For a small projector there's enough lumens to do a respectable job in a classroom, just try to avoid full lighting, please. The P700 had measured a dazzling (for a pocket projector) 741 lumens. That's respectable in a classroom under partial lighting on a typical 60 or even 72 inch screen!
If you really do need to go mobile on batteries, the P700 drops into Eco mode where brightness drops to 237 measured lumens. Perspective time. Back in 1994 in the earliest days of projectors, models, projectors with 150 to 250 lumens claimed to be bright enough for a 25 foot diagonal screen in a hotel ballroom. (OK, the assumption was that the room be fully darkened - no lights.)
The P700 looks very good projecting a 72" diagonal image in a room with modest ambient light
Still you get my point. roughly 240 lumens isn't a lot, but if we were talking home theater type use, that would light up a 60" - 70" diagonal screen to the same brightness found in most movie theaters. That's enough horsepower to be viable in the classroom. Also remember, the long life LED engine will loose very little brightness over several years of operation, unlike lamps which start losing brightness immediately.

Sharpness, won the P700 brownie points - it proved surprisingly sharp for a pocket projector. Color was respectable, not great - our review posts some recommendations for even better color. Skin tones are respectable, but again, hardly great out of the box, but overall color is fine for most business and educational uses.
There are only 3 noteworthy shortcomings, and one not so noteworthy. That's pretty few for a pocket projector. Not so noteworthy i is the lack of 3D, which is not going to be an issue. Even if you need 3D in the classroom, that calls for having a very bright projector, so 3D and pocket projectors simply just aren't a good fit.
More noteworthy: The built in media player, which does support the usual range of photos and video formats, does not support Microsoft office (but can do the usual Powerpoint presentations by exporting the presentation as jpg files). Also missing is pdf support. The 2nd one, is the lack of Wifi. That would have been nice, perhaps the feature most missed.
Finally, The HDMI input does not support MHL for streaming sticks. You'll need to find mobile devices that offer MHL type adapters. Not having MHL is more of a missed opportunity than a likely deterrent to purchase.
