Lets see if this sounds familiar for a typical road warrior pack-out:

Notebook-Power Supply #1
Ipaq-Power Supply #2
iPod-Power Supply #3
External Firewire Drive-Ipaq Pwr supply same voltage
Cell Phone-Power Supply #4

Forget any one of these and your screwed. For a very long time I have wanted to be able to consolidate some power supplies and it looks like a solution may be out there. iGo Juice has a product that received a pretty good review today. I may have to order one of these and give it a go anything I can do to save weight and suitcase space. [ZDNet]
