Ah, never realised that! Thanks Matt.
Seen a 10 v charger for the Power Function batteries, might try that.
Might be cheaper to get a 10V Zener diode and use that in conjunction with a 12 supply.
According to Eurobricks,com, you can use any DC supply up to 20v, one member regularly charges his with a 18v supply.
A sophistical rhetorician, inebriated with the exuberance of his own verbosity, and gifted with an egotistical imagination that can at all times command an interminable and inconsistent series of arguments to malign an opponent and to glorify himself.
