When connecting your ipad to your Windows PC you may get the message Not Charging.
This message appears as your iPad is not getting enough power from the USB port. You can fix this problem by download and installing AI charger which increases the USB port from 1A to 1.2A. Download AI charger here
After installing AI Charger the “Not Charging” message on the iPad goes away.
As AI Charger is increasing the charge from 1A to 1.2A, connecting your iPhone or iPod will also charge faster. iPhones and iPods will charge at around the same pace as though plugged into the wall charger. Although not proven it may also speed up charging to Android Smartphones & tablets.
