Depends on the hub. Without external power supply, normally one - the 0.5A or 0.9A for USB 3.0 do not go very far...

Yes, it does. If you look at the specifications, there's an item "May include a power adapter" and it says "Yes", with the explanation (hover over the small information-i next to it) "You migth need a power connectur adapter to run this product. In this case a suitable adapter is included in the scope of delivery."*. * Typos are not mine, I simply copied what digitec wrote
