Question

I want to be sure a powered hub has adequate power when powering other devices at the same time.

Answer 1

500ma is the current draw

5v is the power

Ohms Law V x I = E (500ma x 5v = 2.5W)

If you look in OSX it will tell you the current draw in the USB system report.

Answer 2

Thank you.

Where did you find the answer? I opened a support ticket asking this and they didn’t seem to know the answer.

Answer 3

I just closed the ticket and see that you went and took care of it. Thanks again.
