Can I use an old wall charger for s8 plus?

[ShortyNed]

So I was wondering if I could use my old LG wall adapter to charge my s8, I don’t want the battery to be harmed. The adapter outputs 5.1 V and 2.1 A. I know it’ll charge slowly but I want to know whether my battery will be damaged

Welcome to Android Central! It won't hurt the battery, but it might charge more slowly.
