It charges through USB, so you can plug it into your desktop or laptop and transfer files to it and let it charge, and then unplug it and take it with you. I believe that the literature says a charge is good for four hours of use, but I've never tested it. Rather than stream video from it (I mostly use it to store movies), I transfer the video to the iPad, and then watch it and delete it from the iPad. So I'm only using the battery on the GoFlex for a few minutes while I'm transferring it.
