Skipper, I believe your problem is that this DAC requires powering from the computer source, and the ipad and iphone won't power more than 100 mA. These idevices work just fine with selfpowered DACs using the lightning to USB adaptor. I found that I could run a computer powered USB DAC like the Meridian Explorer from my ipad by putting a powered USB hub between the two so that the idevice doesn't see a current pull from the DAC. This worked for me. Give it a try.
That said, you are inherently limited on how much music you can store on an idevice, which is not the case for a laptop. So, overall, you are better off using a laptop at home. You may want to bring your idevice and that portable dac with you when you travel though.
