Mobile phone and charger quandry

[Coaster]

I have a nokia 1680 classic that uses a bl5-c battery. The charger (an ac-3x) has worn out, and have a different nokia charger to hand (a nokia ac-11x).
I googled the charger and battery types, and found a nokia asus phone that uses the same battery the bl5-c with the new charger i am now using, the ac-11x

am i right in thinking that if the nokia asus i found online, is supplied with that battery and charger combination, then is it safe with my nokia 1680 classic?
Or have i missed something?

The only things you really need to check are:

a) the plug fits the phone

b) the voltage is the same for the new charger as the old one

c) the current is at least as much as the old charger

As long as all three criteria are satisfied then you should be able to use the charger without issue.
