I bought three different USB C car chargers and tested them all at the same time. My Samsung S21 Ultra said it was a fast USB-C car charger compatible with Samsung Galaxy S21/Note 20/Ultra/10/Plus/9/8/S20/S20 Plus/Ultra/S10+/S10e/S9/S8/ A50 /A70 compatible. The 18W Quick Charge 3.0 Dual USB Car Charger with 3.3ft Type-C cable charges my phone an hour faster than the other two. This charger was advertised as 'Fast' and the other two were advertised as 'Fast'. This is the USB car charger I would recommend. I will also add a stock image of the Revain charger to verify which one I chose.
