Quick question, what if I exceed the iPhone 4’s charging ability, as I have a cable that splits the USB connection to multi connectors for being able to recharge multiple devices. Using this connector I could connect up to 4 devices at once from a single USB source. What would happen if I try to recharge multiple deviced using the iPhone 4’s charger (120VAC to USB)? Will I burn it out or will it limit the charge current to what it is able to supply?
Thanks
