I have several gadgets and a nifty cord setup on my desk that ensures I don't have to connect/disconnect cables; the thing I would love to do would be to keep the gadgets connected overnight (or during the day while I'm at work) to charge regardless of whether there's a computer connected or not. This includes high-power-draw iPhones and iPads alongside lower-consuming gadgets.
My lone powered USB hub is not enough to charge even a single iPhone without having a computer to draw power from. I know most hubs are that way. My question is: are there any hubs that can provide as much power as a connected Mac can (that is, enough to charge at least one iPhone plus another gadget)?
I know some docking stations (e.g. the Thunderbolt version of the Apple Cinema Display) can provide enough power regardless of whether a computer is connected. I would prefer not to get an entire display just for the USB ports though. :)
PS: To keep the cord setup as it is, I need a hub, not a charger: I want to be able to connect the computer to it and see connected devices :)
