Power Surge on USB Port When Plugging in New iPad Air

I got a new iPad Air this week and wanted to transfer my data from my old one tobte new one. So I created a full backup of the old one on my PC (running Win 10 Pro) in order to restore it on the new iPad. But when I plug in the new iPad (using the original cable and a USB-C to USB converter plug), I guess it is drawing too much power, Windows goes haywire and iTunes never recognizes and connects to the new iPad. Tried this on both a laptop and a desktop with the same result.

So what do I need to do? Do I need to spend more money on a powered external USB hub? If so, can anyone recommend a suitable one, presumably one with a USB-C outlet (all the ones I‘ve seen at first glance seem to be just for regular USB plugs)? Any other solutions?
