I took a quick look at the specs. From what I can tell max limit of a USB cable is 5m but this is mostly due to transmittal limitations rather than power. The power limitations come in where your USB port is shared port. If you have two devices on the same port you may have issues with charging.
I think you'd have to a fairly long cable before you saw any significant voltage/current drop though I'd have to do calculations to sort that out.
Did calculation, you can't go past 5m in general, especially when attached to a computer. I'm unsure about when attached to a power plug but my guess is you could possibly get away with a bit longer cable. The main limiting factor is the cable core size rather than the power itself.
Hope that helps.
