What actually makes a mobile device charger faster than another?

[King Belieal]

It is common that you would use a particular charger to charge your phone and the phone charges faster, in that, your battery gets full faster than with another charger.

That has got me wondering. What are the things that define fast chargers? What did they put in a charger that is fast that is not present in a charger that is not too fast?

Every phone have specs charge which the amount of current is directly proportional to the power of the phone. If the charger have a lower capacity, it will take more time for phone to be full charged. When you use original charger of your phone, you will noticed that the phone will not take long before it will be fully charged.

I think the defining factor that affects the charging speed of a charger is the adapter. When the adapter is more powerful than the other, it makes your phone to charge quicker.

Each and every phone is built differently. There are some phones with fast charging up to 18W, there are others that comes with 33W and some higher. Your phone charges faster when using the right charger.

I think a lot depends on how well the phone is designed to be able to use a better charger to charge faster because some smartphones just aren't designed for that.

l too gets confused with that issue so much. That is because l had new phone that came with slow charger and l had to purchase a better charging speed charger for that matter.

If the down board of your phone is functioning properly, and you use a good charger, your phone would surely charge fast.

Even using a better charger might not make much difference unless your phone is actually built for fast charging.

True. My phone can charge full in two hours if I am not using it while on charge. That's just the nature of the phone.
