First, try a different USB port.
Next, charging at a wall outlet is much faster then via USB on your computer.
If charging from another USB port doesn't help, it may be a defective battery. You have 14 days from purchase date to return this iPad for exchange for another.

Thats fine, its totally normal behaviour.
The iPad needs a lot more juice than the iphone or any other device. Most computers USB ports only output 0.5amps which isnt enough to charge the ipad when the screen is on. When the screen is off it will charge but very VERY slowly. itunes will also show it as not charging.
Some modern macs output 1.1amps which is enough to charge, but slowly. Same as using the iphone charger.
The ipad charger outputs 2amps which is what it really needs.
Plug it into your Pc and make a note of the battery %. Leave it for an hour and check again. It should have gone up.
