I have a battery-charger that has an input of 12V/1A
as specified in the specs.
Can I replace the adapter with a 15V/0.8A
adapter ? I also have a 9V/0.85A
Will both work ? Which is more suitable and safer to replace with, or should I buy a 12V/1A
?
I was told 15V/0.8A
and 12V/1A
are practically the save since the have the same Power result in watts of 12W = 12*1 = 15*0.8
? Is this correct ?
