Reports have erupted from iPad users on issues with charging their new devices by USB. The device shows the message “Not charging” eventhough it is connected by USB to a computer or USB hub. Well, it seems to be impossible to charge it through the proprietary USB cable connected to a PC. Nor do any (powered) USB hubs show the ability to charge it. However, it does charge on Apple computers and from AC outlets with the 10-watt power adapter.

What’s going on? Well, the iPad appears to suck so much power that most USB ports simply cannot deliver it to it.

What to do about this? Well, in general it’s best (and quickest) to charge the iPad from your wall socket with the adapter. Otherwise connect it to your Mac and it will charge fast too.

If you need to charge it from a Windows PC and the device shows “Not charging”, simply put it in sleep mode and the device will in fact charge, albeit slowly!
