If you own a modern car, there is a good chance it has USB ports, a wireless charger, or both to charge smartphones. But the in-built car chargers typically don’t offer fast charging speeds. And suppose you have a phone from the Samsung S21 series, which uses the Programmable Power Supply (PPS) feature of the USB Power Delivery (PD) 3.0 standard. In that case, you are better off getting a dedicated car charger from the market to get quicker charging in your car. A car charger is also helpful if you own an older car without USB ports.
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.

Official Car Charger: Samsung L5300 Car Charger
While third-party car chargers are great for charging Galaxy S21, some prefer an official option. If that is the case with you, you can buy the Samsung L5300 Car Charger. It comes with two USB ports – one Type-C that maxes out at 45W and one Type-A that goes up to 15W.
You’ll use the USB-C port for charging your Galaxy S21 series phone, and it supports Super Fast Charging 2.0, meaning you’ll get the fastest possible speed. You can use the Type-A port to charge other phones or accessories. But as Samsung itself notes on the package, it’s best to use just one port at a time.
You also get a Type-C to Type-C USB cable in the box. The charger costs around $30.
