good USB charger hub for charging multiple batteries?

[CaliVaper]

I'm wondering if anyone knows of a good USB charging hub? Not an actuall USB hub that you'd use for connecting multiple USB items to a computer with not enough ports. Just a charger/adapter that plugs into the wall (120v) and outputs via USB connecters.

I checked on amazon, and found a few, but they seem to have crappy reviews and/or wrong specs. Highest one I found had 4usb ports with 500mAh per port 2A total but i don't think it mentioned the voltage output... Don't want ruin my batteries.

What more do you want. The
Charger for the ego is 420ma. Therefore 500 ma output is perfect for them and just about any other USB charged battery I have seen in my admittedly (sp) limited ecig experience. As for voltage they are standard USB therefore 5 volts.
I would just buy a USB Powered Hub and replace the power brick with one rated at the required Ma rating. Monoprice would be a good source with a god selection.
