I do not think so. The iPad only has 1 Bluetooth chipset, so whatever it connects with 1 or 2 Xkey Air, the power consumption will not be big different, it is still under Bluetooth LE standard. From our experience, you can ignore the power consumption from Xkey Air Bluetooth connection. For example we used Xkey Air at NAMM show, for the whole day exhibition with a lot of demo, the iPad still worked well until the show finish at the end of the day.:)
