I have a 12 volt power supply ( not sure of the amps) with an integy 6 channel powerstrip. You could most likely hookup up to 6 chargers to this strip, I have never had that many, the most I hooked up to it was 3 and it worked great. I will have pics up in a few minutes. Asking $37 shipped anywhere in the lower 48
states for another $15 dollars I will throw in a imax B6 charger, it's missing 2 of the buttons. But you can use a toothpick or small object like that to work the button. The internal power supply in the B6 fried so it is wired to hook up to the power strip now. $20 for just the integy power strip
Here is the power supply and the power strip.....
And here is the imax B6 balance charger.....CHARGER IS SOLD!
