Good to know, I've been using my eGo PT and charging other batteries on my hub with no issues but its running off AC not my PC so maybe it puts out enough power.
TL - The important thing about using a hub or single adapter is the maximum amps each port will support. The "experts" here claim that .5amp is not enough for passthroughs. They may work for awhile but eventually you'll have problems. And I have. Mine worked fine for the first week or so, and then they started working only part of the time and would quit for a few seconds. Now, I'm mainly using my eGo battery when I'm home, because I'm tired of the problems I've been having with the dang passthroughs.
How many amps does each of your 12 ports support?
