I believe you are looking for a Wyred4Sound PS-1.
There is a base unit which you can add up four additional outputs with different voltage ratings. Three regular 1 amp outputs, plus one high current 3 amp.
Wall wart removal...why no products that can handle multiple devices?
If you're like me I've got quite a few wall warts all with varying degrees of electrical needs. Are you aware of any product that could eliminate the need for multiple wall warts and replace it with a single device that you plug your devices into that without the need for all kinds of wall warts?
Here's possibly something similar and I don't know if this would work but it gives an idea of what I'm talking about.
