Super Fast Charging (SFC) 2.0 requires a USB Power Delivery (PD) 3.0 compatible device supporting Direct Charging. Devices lacking USB PD 3.0 standard or Direct Charging will charge slower than SFC speed. Charging speed varies based on usage patterns, conditions, connected devices, and other factors. Charging performance may be affected by device model, cable quality, and environment. To optimize results, use genuine Samsung 5A cables provided in the original packaging. Compatibility with additional devices can expand over time.
