That is the question. Wonder how to shorten the time and effort to charge 6 batteries.

the stock is 100w. and yes the 180 does charge faster, but if you want really fast pick up the Hex charger ($299usd) it charges 6 batteries at the same time, unlike the quad charger that does one by one

Like TrueGreen said, the stock charger is 100W. Certainly, 180w batter charger charges faster than the standard one?
