How-to Charge iPad with Computer
Many Apple users have complained that their iPad shows “Not Charging” while plugged into their computer. The explanation for this is that the iPad requires more amp than the USB port can supply.
Apple’s support states, “iPad will charge with any Apple USB Power Adapter and will also charge, although more slowly, when attached to a computer with a high-power USB port.” Most computers have standard USB ports that do not provide enough amp to to charge the iPad with the screen on. The power required to keep the screen on exceeds the charging rate of a standard USB port. Therefore, by keeping the screen off, the iPad will charge slowly.

ASUS has provided a free simple program called ASUS AI Charger that boosts the charging rate of the USB ports. It works by boosting the port to a higher output. Many report success after installing this utility.
I really need help with my ipad not charging when it is plugged into the wall. It does not say “not charging” it just does not have the lightning bolt when it is plugged in and it runs out of battery, BUT if I turn it off for a day while it is plugged in and then turn it on again it got about 10 percent more. But it still doesn’t say it is charging. Please help.

Some key takeaways are:
The iPhone power adapters are 5 watts and will charge your iPad very slowly. The iPad chargers has more than twice the iPhone’s power at 12 watts. Off brand chargers varies in power and are not recommended.
Please use an official 12 watt Apple charger to charge your device. Please test that this works for your device (borrow your friend’s charger) before you go off buying a new charger.
I always turn off my iPad Air when charging with the case cover closed and it always charges fully.
