What could be the reason why another charger doesn't charge my phone?

Question

Lately, I've realised that only my charger charges my phone. I've tried other people's charger before and they worked just perfectly until recently when they don't work on it again.

Answer 1

it may not charge due to the problem in charging slot.

Answer 2

Firstly, every phone has it owe charger because the charging capacity of every phone differs. So your phone may not be able to charge with other charger because the charger is not compatible with your phone or the charging capacity of the other chargers are not enough to charge your phone.
