impression upon open the box , I be very impressed with the weight , size and look of this projector . it be very small , yet have a nice quality look and feel . the monster battery pack give it a heavy , but not-too-heavy feel . there be a nice selection of accessory in the box , include a ac adapter , composite video cable , VGA cable with audio plug , triple rca female to female adapter and a Apple adapter -lrb- although this may not be include normally -rrb- . I have in mind when testing that this be not a 2500 luman projector nor be it to be rate base on its comparison with one . feature the battery feature be just awesome . no regular projector can do that ! it do have a small kickstand that tilt it up slightly , but also have a mini flexible three-legged tripod to make it easy to manage steeper angle or uneven surface . -lrb- it have a universal tripod screw hole , so any tripod would do . -rrb- it have a speaker inside -lrb- 0.75 watt to be exact -rrb- . input keep in mind that the input be analog , so no input hdmus , DVI or DisplayPort without downgrade it first to analog with equipment . you device must have a analog output . out-of-the-box it can do a analog VGA jack from a computer and a plain yellow rca composite video input . many device like dvd player , comcorder and the iphone\/ipad can do analog video out today , but new device like many android smartphone and flip cam do digital only , so be careful . here be the other cable that be available :  3M Pocket Projector MP160\/MP180 Cable for iPad , iPod , iTouch  this be the ideal situation for this projector . in this scenario , it look great . it have all the brightness you need to show you family video or picture . I then try it at nighttime , but with light on . while it be not terrific , it be still viewable for picture or video , especially if I keep it within 6 foot of the wall -lrb- thereby limit the picture size -rrb- . the same go for daytime while block some ambient outside light -- it be not bad view photo and video . a high contrast powerpoint presentation , on the other hand , look good in each circumstance . testing device first I test it with my iPhone 4 . I could not quite get the connector to plug into the phone with my case on -lrb- although I can get it to work if I do not move they too much -rrb- , so I put it in my wife 's iPhone 4 . it do what Apple allow the a\/v adapter to do -- play a photo slideshow , play video , YouTube and a few other thing . next I follow 3M 's recommendation and try the  Apple iPad Dock Connector to VGA Adapter -lrb- mc552zm\/b -rrb-  a few time I have to fiddle with unplug and replugg , but it do do mirroring with the ipad 2 and iPhone 4 . however , there be a strange flickering every few seconds that make it unusable with both device . I try with a composite video adapter from the ipad 2 , but it do not do mirroring with that cable . I next try my laptop with the VGA adapter . I put the computer into presentation mode and the projector take the 1280x768 resolution and it display it well . the image be stretch vertically since that be not the native resolution . I find that PowerPoint presentation , picture and video look good just like this . however , any fine text be too blurry to read . I pull the resolution to 800x600 and it look perfect ! so , that make this just like many of the under $ 500 full size projector on the market -- 800x600 natively and it adapt higher resolution down to that level . here be the resolution it can downscale itself : 1024x768 , 1280x768 , 1280x960 , 1440x900 -lrb- and 640x480 , 800x600 -rrb- plus three Mac resolution . next , I try a dvd player , which work great , since the dvd player have a composite video jack -lrb- remember , no digital input on the projector -rrb- . as for the audio , it sound like a small and tinny speaker -lrb- because it be -rrb- and sound much worse than my laptop 's speaker , but sound similar to a smartphone . just like the 32 luman brightness , this be design for a small audience of a few people , so the speaker do its job . battery i run a test and allow a iPhone to run through a slideshow of picture and video , which a small amount of time take by video with audio go through the speaker . it be able to make it for two hour , and I be very impressed . OVERALL if you get a full understanding upfront of what this can do and what it can not do , I would recommend it .
