Has this happened to you, do you think if there is something wrong with the charger, or there are issues with battery, or electrical outlet.

It's because they are not the original charger. If it's the follow come battery charger, it means the charger have become faulty and it's going to be in your best interest to replace the charger as quickly as possible before it completely damage your battery itself.
