Fast Charging: The Baseus car charger supports four fast charging protocols. Qualcomm Quick Charge 4.0 charges your device four times faster than a standard charger. Additionally, the backward compatibility with Quick Charge 3.0, 2.0, AFC, and MTK ensures the fastest charging option. The Quick Charge 4.0 option is available via the Type-C port. QC-compatible phones include the Xiaomi 10/9. With the Huawei Fast Charge protocol, your device charges faster and does not heat up as much during the charging process. Compatible phones include the Huawei Mate 30 and Honor Magic 2, for example. Like Huawei, Samsung also has its own fast charging protocol. With Samsung Adaptive Charge, your phone charges much faster than with a regular charger. Samsung's technology charges models like the S20, S9, and others. Power Delivery is a high-voltage charging standard that quickly and safely charges your device.
