As mentioned, all Samsung S21 series phones, including 2021’s Galaxy S21, S21 Plus, S21 Ultra, and the brand-new S21 FE, use USB PD 3.0 PPS for fast charging. So a car charger will need to support both USB PD 3.0 standard and its supplemental PPS specification to offer top charging speed with any of the Samsung S21 phones. Also, it’s important to remember that the Galaxy S21 phones support 25W wired charging, so you will also need the charger to be rated at 25W or more.
With the basics out of the way, it’s time to look at the best car chargers for Samsung Galaxy S21, S21 Plus, S21 Ultra, and S21 FE.
