This question already has an answer here:
I have two A.C adapter chargers giving an output of
5V DC 350mA and the other one with
5V DC 450mA. Is it possible that I could use a
5V DC 350mA to recharge a phone which came out with
5V DC 450mA charger and vice-versa?
I have searched the google and found that using a lower amperage supply charger for the phone that came out with or requiring higher amperage charger could be damaged by it.
How much does this matter with
450mA or what is the difference between them?
