Here is my Axim X50v with the Pelican PSP Power Brick

I posted that months ago, and I still use it to this day -- without fail. I get about two full charges from the brick, with the Axim at about 10% battery life.
Despite the picture (with the Axim turned on) -- the full charges I get are obviously with the Axim turned off.
