PD Adapter and power adapter

[sidharth3768]

Anyone please explain the diffrence between 25w PD adapter and 25w power adapter

Which one is better to use with my galaxy A55?

The difference between a 25W PD (Power Delivery) adapter and a 25W power adapter lies in their charging technology, compatibility, and performance.

*25W Power Adapter (Traditional):*

1. Outputs: 5V/5A (25W)
2. Charging technology: Traditional, non-smart charging
3. Compatibility: Works with most devices, but may not optimize charging speed
4. Cable: Typically comes with a standard USB-A to USB-C/Micro-USB cable
5. Charging speed: Dependent on device's charging capabilities

*25W PD (Power Delivery) Adapter:*

1. Outputs: 5V/5A (25W), 9V/2.77A (25W), or 12V/2.08A (25W)
2. Charging technology: Smart, adaptive charging (PD 3.0)
3. Compatibility: Designed for USB-C devices, including smartphones, laptops, and tablets
4. Cable: Requires a USB-C to USB-C cable (certified USB-IF)
5. Charging speed: Optimizes charging speed based on device's capabilities

Key differences:

1. *Smart Charging*: PD adapters communicate with devices to optimize charging speed and voltage.
2. *Faster Charging*: PD adapters can charge devices faster, especially those supporting Quick Charge, VOOC, or PPS.
3. *Multi-Voltage Support*: PD adapters can output multiple voltages (5V, 9V, 12V) to match device requirements.
4. *Safety Features*: PD adapters often include built-in safety features, such as overcurrent protection and voltage regulation.
5. *Universal Compatibility*: PD adapters work with a wider range of devices, including laptops and tablets.

In summary:

- 25W Power Adapter: Suitable for basic charging needs, compatible with most devices.
- 25W PD Adapter: Ideal for fast charging, optimized for USB-C devices, and supports multiple voltages.

When choosing between the two:

1. Check your device's charging capabilities (PD, Quick Charge, VOOC).
2. Consider the adapter's compatibility with your device.
3. Prioritize PD adapters for faster, smarter charging.

25W Power Adapter has GaN(Gallium Nitrate) Tech too .And 25WPD has silicon Tech

[Wodehouse]

GaN is more power efficient with lesser heat loss compared to Silicon. Silicon has tendency to heat decreasing power to heat ratio. Besides GaN chargers are compact and can handle higher frequency and voltages contributing to faster charging speeds. GaN is more prefered by good brands.

25W Power Adapter is based on GaN technology.

Which one is better among the two?

[Surya230]

Both are the best options for your Galaxy device. You can pick any of these.
Samsung stops selling PD Adapter.
