I did a job one time, and a construction worker there, had a silver (guessing aluminum) suite case that had about 10 power charging stations for 18V batters in it. He plugged one cord into the wall, and it powered all 10 stations at the same time.

Been looking every where for something like that, but can't find one, so I am guessing it was home made or something.



Anyone, have any ideas on how to do something like that?
