The output voltage available at a USB port is controlled by the regulator in the computers power supply. It is fixed, you can not change or control it.
The maximum current which should be drawn from a USB2 port is 500mA, from a USB3 port it can (I believe) be up to 850mA.

It's an output. I think. The usb port is already in there, so it should be an output. An input is something you put in, and an output is something that comes out. Hope this helps. :)
Is a usb input or output?
input
How much power can be supplied to any appliance by a laptop?
Assuming your using a USB port to power your device, the answer is 2.5 Watts. A maximum of 500mA at 5V can be drawn from a Usb port. Power = Current * Voltage, which is 2.5 Watts by 0.5 Amps giving you a power output of 2.5 Watts http://en.wikipedia.org/wiki/USB#Power http://en.wikipedia.org/wiki/Power_(physics)#Average_electrical_power_for_AC
Is a USB stick input or output device?
