Powered USB Hub for Charging eGo Battery(ies)

[ShoeQueen]

Greetings to the Vaping Nation!
I'm seeking a USB Hub that can be used to power multiple eGo battries. I know (now) that the USB Hub needs to be 5V with a steady out put of 500mA per port.
Unfortunately, all of the Hubs I find online will not divulge such techical information. Can anyone provide links to an appropriate USB Hub for charging multiple eGO batteries?
Amazon is my first choice for my shopping needs, but I will gladly go to any recommended seller.

Thanks, and Happy St. Patty's Day!

All USB hubs have the same electrical specifications: they're part of the USB standard. So, take your pick!
