In real terms USB sockets frm your PC/MAC won't push out enough voltage for the iPads large battery to charge; however if you are running low on juice, then plugging the device into the USB socket will prevent further discharge of the battery.
To charge the iPad you must connect to a power outlet. It all comes down to the physical size of the iPads battery and the voltage required to charge it - the trickle from the computer isn't sufficient and hence why, when you plug it in, it will say 'not charging'. To look at it another way, MacBooks of different sizes (13/15/17) have different mains chargers with differing power outputs (60W/85W). You can use any Apple MacBook charger in any of the MacBooks, but it might take longer for your MacBook to charge if you use the 'wrong' one: i.e. you can power and charge. 13" MBPro with a 85W charger, it will charge your device quicker as opposed to the suggested 60W charger. |
