Hi all. I found through a lot of trial and error that I can only use my iPad mini 2 and my iPhone 8+ at the same time if one of them is using the camera connection kit to boost the power (rather than the additional ICA USB cable I bought). Otherwise, regardless of which order I connect the devices in USB 1 and 2, one of them will stop working after a few minutes. It's like the power rating from the USB ports is not as much as it says it is. One device will consistently stop charging and loose connection to the ICA4.
Is anyone using two iOS devices trouble free?
I know that both devices trickle charge on a small iPhone 1 amp charger, so in theory the power from the ICA USB ports should be enough.
