I need to replace an AC adapter that went out. Original is 12V 225mA. I have several 12V 1000mA. Any problem using 1000mA rated unti with 225mA machine?
Absolutely no problem as long as it has the right plug. The 2000ma
units are almost all REGULATED switchers, so do not have overvoltage
problems like were sometimes experienced with using oversized
transformer type adapters.
