S6 Fast Charging

[Brozap]

I have my factory charger that charges well and fast. Is it possible to buy an aftermarket one that would support fast charge and be longer than the original? Thanks

I think you're referring to Quick Charge and in this case, a Galaxy S6 is compatible with Quick Charge 2.0.

You're going to need a Quick Charge 2.0 charger if you want to take advantage of the type of charging that you're talking about.
