Right. I'm willing to pay good money for a USB hub that actually works for all these sorts of things. The question is if anybody here is aware of such a hub. The Amazon reviews for the CyberPower 7 port hub make it seem promising. Here's a Pluggable 4-port hub that explicitly supports the USB battery charging spec. And D-Link also has a hub with two "high power" ports. It's unclear exactly what the "right thing" to buy might be.
