I have a Hyundai power bank. 4000 mAh but only a 5V output which would take ages to charge your air. Look for something with at least 10V output. My power bank I use mainly for my iphone, Bose headphones and wifes blackberry.

Like Trance Omega said, just get a USB battery pack in the 5400 mAh and higher range. The iPad Air's battery capacity is 8820 mAh so you're not really going to get a full charge.
What you really should be doing is getting a power adapter for whatever country you're going to and charge the iPad every night.
