Does a USB hub drain more battery?

[Bruno Vincent]

I have a laptop and it doesn't have enough USB ports for what I want it to do...

Would buying a an external USB hub drain more battery?

For example:

a.
-Mouse connected to laptop native USB port
-Wifi stick connected to laptop native USB port

b.
-USB hub connected to laptop native USB port
-- Mouse connected to external USB hub
-- WIFI stick connected to external USB hub

I would get a hub with no light on it.

I haven't heard of any USB hub that doesn't require some power to maintain transfer speed. If it doesn't use its own power - by way of a wall plug - it has to draw power from your laptop. How much will depend on the number of USB ports, and possibly the type/generation of USB used.
