How is this powered?
I read through specs and several reviews, but I can't discern how it gets power. Does it have a battery/rechargeable? Does it have to be connected to a power source via usb? I want to know how "portable" it is... thanks!
a battery rechargeable, just plug in to a usb port and will charge. I use mine for short periods while I transfer videos or pictures from the iPhone to the usb like 10 - 20 mins then I turn it off, probably two hours or so I've been doing this procedure.
