Here is a quick article I did about using 120VAC to charge batteries with a Classic.

Nice write-up. Do you think Midnite will release a "package" to charge from the grid or other A.C. source i.e. as a system? Granted, it's not hard to add the bridge and other components...

Ok I pulled the article do to concern that it may break Classic's so for now this is an unsupported feature sorry Guys my mistake. Robin has a concern that the utility grid is to stiff and it will break the Classic and that it may work with resistance in series. Feel free to PM me with thoughts or ideas on this subject.
