An iPad Air 13 inch with the M2 chip that will not charge has the same short list of causes as other iPads, the cable, the adapter, the port and a pause by the software, and the large screen means it takes a long time to charge from a weak supply. The Air charges through a USB-C port. Use the adapter and cable supplied, or an adapter of about 20 watts or more with a cable that carries power, plugged into a wall socket. A low-power adapter charges slowly and may not keep up while the iPad is in use, so a 13 inch screen in use can drain as fast as it charges;
The checks in more detail
stop using it for a test. Look for the lightning bolt in the battery icon and watch the percentage over ten minutes. Inspect the port and the cable. Lint in the USB-C port prevents the plug seating, so lift it out gently with a wooden toothpick with the iPad off; do not use metal. Check the cable for kinks near the plug and try another cable and adapter. Restart the iPad, pressing and releasing Volume Up, then Volume Down, and then holding the top button until the logo appears. A flat iPad may need half an hour on the charger before it responds. Settings and heat also matter.
Optimized Battery Charging pauses at eighty percent and shows a message; tap it to charge to full, or turn it off in Settings, Battery, Battery Health and Charging. A hot iPad, perhaps from a sunny window or a thick case, slows charging, so let it cool. Update iPadOS. If the iPad charges with one adapter and not another, the adapter is the issue. If it will not charge with a good cable, adapter and port, and a restart, the battery or the port may need service, and Apple can test it with the serial number. Do not use an iPad whose back is bulging.
The 13-inch iPad Air has a bigger battery than the 11-inch model, and it takes noticeably longer to fill from a low state on a weak charger. A 20 watt adapter charges it fully overnight, but a 12 watt iPhone adapter can leave it well short and, while you use the iPad heavily, can even let the percentage drop slowly. Charge it with the supplied USB-C cable and an adapter of at least 20 watts, and close demanding apps while it charges. If you charge through a hub or a dock, plug the iPad straight into the adapter for a test, because many hubs share their power among several devices and limit what the iPad receives.
