The more I read the more confused I get. I want to connect a 5th gen iPad to the Nikons to transfer images when on trips. There seems to be two Apple.lightening to usb camera adapters most commonly mentioned. The lightning to USB and the lightning to USB3. I know in addition I may need a short cable to go from the end of this device to the camera port? I keep hearing issues about not having enough power and adding hubs in some instances. At a ten buck difference I don't care which one I buy as long as it's gonna just plug and play. The last thing I need is another adapter in my junk drawer. Any suggestions folks?
