usb power strip

Hi all just thought this would be a good project for the show.

A 6 gang usb power strip, as more and more devices are running of usb power. I for instance have 2 phones a Samsung tab (but till only charge when the usb is plugged in to the wart) and a e-book all which use usb for charging and i think 1 wall wart would be better than 4+. But I don't know how many amps I would need the wart to be and how get past the fact the Tab will only charge when plugged in to its own wart and not in to a PC. this might be a good one to pull the ic and soldering eps together.

You can look at the amperages on the charger but 1000 ma is good for normal usb devices (infact with lots to spare) and 2200 ma can be used to charge most tablets. One thing to keep in mind is sometimes you have to bias the data lines. You need to do this because some devices are made to only accept a charge from a computer or special chargers. http://www.instructables.com/id/How-to-get-your-iPod-to-charge-with-your-homemade-/#step1 shows how to do it for iPod devices, so I would check to see if you need to do this with your devices.
