Fast charger transfer Ac Or Dc current on phone?

Welcome to Android Central! All devices require DC. The charger converts the AC current from your wall outlet to DC. Read this: https://www.wired.com/2014/11/charge-dc-phone-ac-source/

I know that, but since I bought and test many fast chargers they were all ac current. But all of my normal chargers all dc.
Any idea?

Sorry, I'm not quite understanding. The DC chargers I can think of are car chargers (the kind that plug into the car's cigarette lighter socket). Where do you plug your normal DC chargers into?

All of my Normal & fast chargers are wall chargers.
Input ac and output should be dc. In normal chargers convert ac to dc. But fast chargers ac to ac . Pls test your fast chargers & ans me.

No. Those still convert to DC. Rate of charge doesn't change type of current.

That still doesn't make sense to me. A phone can't charge directly on AC current. The AC current has to be converted to DC current. Are you referring to what's displayed in the charging screen, where it might say "Charging on AC" when you're plugged into a wall outlet, as opposed to "Charging on USB"?

Test your fast charger using a ac current tester.pls.
