"Not charging" actually charges

When "not charging" is displayed, I'm pretty sure the iPad is not charging.

Note: Some USB 2.0 ports and accessories do not provide enough power to charge iPad. When this occurs the message "Not Charging" appears in the status bar next to the battery icon.

The fastest way to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter. When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge, but only when it's in sleep mode. Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.

Actually this has been tested...if the screen says not charging, it maintains its current charge if connected to USB 2.0. If you turn the screen off while connected to a USB 2.0 port when the iPad displays "not charging," your iPad will charge at a very slow rate...I'm not sure if it will be fully up to 100% from say 10% overnight, but it's possible...

If the iPad's screen is on, the iPad isn't in sleep mode. If "Not Charging" is displayed in the iPad's menu or status bar, it is not charging.

Many times I have noticed that my iPad is at, let's say 87%, when I connect it to my AC powered CyberPower hub. I will then continue using the iPad for a few of hours. And many times, when I'm done using it, it will be at 100% even though the entire time it said, "Not Charging". Perhaps it is because I'm using AC power?

It probably may charge a little even if it says it's not. But I'm almost positive (just can't site the actual reference) that it won't do any harm to the battery's life.
