I'm pretty sure its 15VDC, 1A. but either way its more than a computer's USB (5VDC, 500mA).
Think of the cord as a pipe in your house. The Voltage (VDC) is the size of the pipe, and the Current (A, or mA) is the speed at which the water flows through the pipe. If you slow down the waterflow, you'll still get the water you need, but a little bit slower. If you shrink the size of the pipe you get a lot less water at a time making it much much slower, probably not even enough to replace what is being used at the time.
Hope my analogy helps.
