I have an Apple wired keyboard plugged into a USB port on my 30" ACD. How much power am I getting through the two USB ports on either end of the keyboard?
The reason I'm asking is because I'm getting tired of replacing batteries on my magic trackpad. Since I work from home, the trackpad is on constantly. I use rechargeable batteries, but after a while even they don't hold a charge any more. I see that Mobee sells something they call a Power Bar. Since the trackpad is always a few inches from the wired keyboard, using the Power Bar and the supplied USB cord, I could turn the trackpad into a wired device and never have to worry about replacing the batteries again. The question is whether there's enough juice flowing through that USB port to support the Power Bar which according to the tech specs uses at most, "200mA Max"?
It seems like everything I've ever tried to plug into that USB port at the end of the keyboard needs more power than it can give. For example, I can't charge / dock my iPhone, kids iPod Touch's, or iPads through that port which is frustrating!
