Fast Charger 3.0 and the adaptive fast charger, what is the difference?!

[keavlar]

Hey guys.

So I need help, please.

 

I have the Samsung s8+ and Samsung Tab s3.

For both, I use the wall charger that came with it. 

"Samsung Travel Adapter with adaptive fast charger ". (output 9v - 1.67A  and 5v - 2A)

I would like to know if I will buy something like USB Car Charger with Quick Charge 3.0 , will it make any difference in charging the same devices, and will it damage them in some way?

I mean, I read somewhere that these devices do not support the fast 3.0 charge, so it can't be used with them. 

Same goes with the wall charger. 

Is it true?

Is this device any good for use as well?
