How to Choose Between Apple and Samsung Fast Chargers? Full Guide to PD and PPS Differences

Why does the same USB-C charger deliver different charging speeds for iPhones and Samsung phones? The answer lies in fast charging protocols. This article explains the fast charging differences between Apple and Samsung devices and provides practical recommendations for choosing a universal fast charger.

Same Wattage, Different Charging Speeds — The Key is the Charging Protocol

Most people only look at wattage when buying a charger, but ignore protocol support.
For iPhones, as long as the charger supports USB Power Delivery (PD), fast charging will activate.
For Samsung flagship phones, maximum fast charging requires PPS (Programmable Power Supply) support.
⚡ Key point: Two chargers with the same wattage may charge iPhone and Samsung devices at very different speeds due to protocol compatibility.

Fast Charging Basics: What is USB Power Delivery (PD)?

USB Power Delivery (PD) is the universal fast charging standard that negotiates voltage and current for faster and safer charging.

  • Without fast-charging protocol support, both iPhone and Samsung will fall back to 5V standard charging.
    • PD is the common foundation for both Apple and Samsung fast charging.
    Most certified PD chargers can enable fast charging on both devices.

If the PD protocol does not activate, both brands revert to slower 5V charging.

Apple Fast Charging: Stable and Highly Compatible PD

Apple devices (iPhone) rely primarily on USB-PD:

  • Features: stable, safe, and widely compatible
    • Typical power range: 27W–40W, optimized for heat control and battery lifespan
    • Advantage: most PD chargers can fast charge iPhones at full speed, making charger selection simpler

Samsung Fast Charging: Dynamic PPS for Higher Efficiency

Samsung uses PD, but also adds PPS (Programmable Power Supply), which allows the charger to dynamically adjust voltage and current for better efficiency, reduced heat, and improved battery health.

A charger that supports PPS can activate Samsung’s Super Fast Charging (SFC) mode, offering a better experience compared to PD-only chargers.

How to Choose a Universal Charger for Both Apple and Samsung?

For iPhone users

  • Priority: stability & durability
    • Look for chargers with USB-PD support
    • Recommended wattage:
  • iPhone basic models: 20W+
  • iPhone Pro Max / MacBook Air: 30W–70W
  • MacBook Pro: 70W–140W

For Samsung users

  • Priority: PPS support
  • Recommended wattage: 25W PPS or above for optimal Super Fast Charging

Universal Fast Charger Requirements

To support both Apple PD fast charging and Samsung PPS Super Fast Charging, ensure the charger includes:

  1. USB-PD support (required for both brands)
  2. Full PPS support (required for Samsung flagships)
  3. Multi-device compatibility (phones + tablets + laptops)

This setup covers most real-world scenarios and avoids buying different chargers for different brands.
