If you plug the ipad into a standard USB charger such as for the iPhone or direct computer connection the power output is not great enough to charge it whilst the screen is active.
You will notice in the upper right it says not charging. Once you turn off the display the unit will slowly charge, you can test this by connecting it to your computer and leaving it overnight then checking the charge difference in the morning.
The latest Macintosh computers will have one high power USB port that will charge the unit. Some other manufacturers also use high power USB for external DVD burners for laptops. I have read that Dell and Acer both do this.
The dock connector is proprietary but it is also ubiquitous. When traveling, if you need a cable you will always be able to find one, unlike some weird mobile phone charge cables that are USB but only fit the one phone & some cameras do this too.
