I use the 2 USB chargers to charge my iPhone and iPod nano simultaneously, while using the outlet plugs for a light, clock radio, phone and iPad. The USB chargers will not charge my iPad, even when the second USB is unplugged. They don't seem to have enough power for the iPad. This is not a big issue for me, because I use the 2 USBs for other devices, but it will be for others. You can still plug your iPad power adapter in one of the 6 outlets.
