Power/charging Problem

Try substituting the USB cable and the power brick, one after the other. Failure of a cable is the most likely culprit. If necessary, visit an Apple Store or a friend to have your iPad checked out with their known-good peripherals. Good luck.

Bring your iPad Air 2, charge cable and charging/power block into your nearest, “local” Apple Store for diagnosis, evaluation and potential options.

If your iPad Air 2 is in good shape, cosmetically, if a possible diagnosed battery failure, an exact replacement iPad, in lieu of an actual battery repair/replacement, will cost approx. $100 U.S.D., plus tax.

Battery replacement is cheaper than purchasing a new iPad.

Best of Luck to You!

you should probably take it in to the Apple store, and if you don’t want to, you can try powering it off. I had that problem and that is why I bought an iPad Air 3.
