We've had a lot of talk about USB standards here lately!

For our family's next trip, I'd like to leave the portable power strip behind - along with as many USB chargers as possible - and just bring a hub and cables. Is this going to be possible?

I have an Anker hub with 9 ports, but two of those are advertised as charging ports. I've charged some light devices off the other ports, but I guess I don't understand enough about USB power to know what's going on in there. Is there any hub/device on the market that charge, say 5 phones at once? Is this basically what I'm looking for? Even if it is, I'd love to understand this issue more...
