USB devices need 5 volt supplies, the current draw differs depending on the device - my mobile phone charger is rated at 0.7A, my Hudl 2 tablet charger is rated at 2.0A. AFAIK pedal supplies are usually in the 9 to 12 volt range so I reckon your Voodoo Lab unit would kill a USB device. Depending on the current draw you might be able to use a phone charger or similar.

If you've got a courtesy IEC socket on your Voodoolab then you could run a socket off that and plug your charger into it. It's what I do for storing crib sheets on my phone:

I doubt there are any good pedalboard power supplies that can give you 48W. If you really need that much power, use a dedicated PS like bigbassbob suggested.
