You can get a USB to Lightning adaptor for charging. These little gizmos are primarily for iPhones, to meet a (voluntary) European standard for phone charging; but they will work on an iPad, providing the power supply has enough power.

There's been talk in Europe of making USB charging a required/regulated port for device charging. Personally I think it would be a mistake to lock an industry that's moving this fast into a connector standard that is already starting to fall behind. The next USB connector will 'probably' be a lot more like the Lightning connector. Be a shame if Europe found itself stuck with a connector that is good for little but charging. That or phones would be back to having a separate port just for charging, as they did not so long ago.
