Will USB port charge devices?

[Arizona Willie]

I have a device that charges from a USB port and I wondered if the USB port on my Surface Pro I will charge that device if it is plugged in.

I hesitate to try it unless it is OK to do.

The worst that can happen is that it won't charge or won't charge fast enough.

It depends if the device requires the full 5 AMPs or can get away with the 3ish AMPs the SP delivers....the power brick does deliver the full 5 AMPs.
