The one from the Amazon link you still need cables but not the wall adapters
With the Amazon link device it charges the iPad at full speed , is like using the wall plug that came with the iPad , but now you have 6 ports
This thing or the anker version is useful if you travel or at home if you have a lot of usb devices to charge or usb devices the need power like speakers or clock
or a big family with lots of iOS devices , you put this in the living room
Everybody charges there iPads & iPhones at the same time with one wall plug
