Good point. Ipads are real 5v power hogs as compared to other USB charge devices. The OEM Apple Ipad charger is 5 vdc 2.1 amp. Many USB adapters and chargers are only 0.7 amp or so.
Were I to put the effort into installing a combination USB/120 volt receptacle I'd look for the USB unit to be 2 amp minimum. That said, adapters with power strips is what we use.
