is it possible to locate online a projector which can send an image stored on a USB flash drive to a wall?

GMartin used Ask the Experts™
Hello and Good Morning Everyone,

          I am wondering if there are projectors which can project an image from a USB flash drive.  In concept, it would be similar to taking an image on a transparency but instead taking it from the USB flash drive and projecting it onto the wall.  The projector would also need to have controls for shrinking and enhancing the images and well as controls for clarity of the image.   Additionally, it would be nice to have a internal rechargeable battery which will hold at least 2 hours or more of charge.  

          If what I have just described is available on the market, could someone provide a online purchase link?  If it is not too expensive, I would like to purchase one.  I have an art and painting project which can be made much easier and with greater precision if I have a digital style projector.

           Thanks in advance for any feedback given to this question.

Well, the above projector has
Brightness of projection: 50 Lumens
This requires normally a dark room..

Depending on the project type, I would consider borrowing it. Otherwise I guess, you will need to spend at least some tons on it.

Any projector operating off batteries is not going to be able (as much as the manufacturer or advertiser thinks) give out a very bright image. For a good image that is able to be seen in a properly darkened room I'd recommend  a minimum rating of 1500 lumens. If the room you're in can't be darkened well, the minimum would be 2800 lumens. A battery operated projector might be able to put out this brightness, but only for a few moments, and considering you're talking about plugging a USB stick into it (which will have to have 5V supplied to it continually through the USB port to make it run) there may not be enough power in the battery to run the projectors electronics let alone light the lamp.
