What is the max output current for a USB laptop port?
I have connected to my HP/Compac NC6120 laptop a pair of speakers system in the USB.
How many amperes does the USB port support?

The speakers system drains about 400 mA.

Answer
The specification is a maximum of 5 volts & 500mA. That's why iPads need a special charger. They require 10 volts.
