The quickest way (and really the only 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 (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). 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.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

In rare instances when using the Camera Connection Kit, you may notice that iPad does not charge after using the Camera Connection Kit. Disconnecting and reconnecting the iPad from the charger will resolve this issue.

Hey Tex, the iPad mini uses an iPhone style charger, not the 10 watt charger. We all love your cut and paste links, but some just are not accurate for the mini. Gotta do a bit more work, bud.

I experienced the "USB drawing too much power" error when trying to set up my iPad Mini, even with no other USB devices connected (except for the keyboard). In frustration I tried using the USB cable from my daughter's new iPod Toch, and the iPad Mini synced perfectly. So it looks like the problem was with the cable. Now I have to figure out if its worth retuening the whole thing, just to get a replacement USB cable. Probably not unfortunately.

Bad cable with the issue for me as well barney97. Thanks for the heads up.
Hopefully you won't have to return the entire thing to get a replacement USB cable. If you have a local Apple Store, they'll probably replace it for you free of charge (given that the issue is pretty easy to reproduce). Otherwise I'd just call the Apple support line and explain the issue. Every time I've had to deal with them, they've been more than accomidating.
