Choosing the Right Adapter For Galaxy S25 Ultra and S25+
It’s important to understand the charging adapter specifications needed to maximize charging speed and ensure full compatibility with your Galaxy S25 device.
For reference, the S25 Ultra supports 45W Super Fast Charging 2.0. With its 5,000mAh battery, it takes around 57–60 minutes to charge from 0 to 100% using the official Samsung 45W charger.
Here are the key factors to consider when choosing a charger:
- PD 3.0 Support: The S25 Ultra and S25+ both feature Super Fast Charging 2.0, Samsung’s proprietary charging technology. This requires a 45W charger with PD 3.0 and PPS (Programmable Power Supply) for optimal charging speeds. It’s important to note that not all 45W PD chargers are compatible with Super Fast Charging 2.0.
- Power Output (Wattage): Look for a charger with a power output of 45W or higher. While a higher wattage charger won’t harm your phone, it won’t charge faster than 45W.
- Consider your other devices: If you have laptops or tablets that use USB-C PD charging, a higher-wattage charger (e.g., 65W or 100W) may be a more versatile option.
- Safety Certifications: Look for chargers with safety certifications like UL or CE. These certifications ensure the charger meets safety standards and protects your device from damage.
- Form Factor and Portability: Consider whether you need a compact charger for travel or a larger one with multiple ports for charging multiple devices simultaneously. GaN (Gallium Nitride) chargers offer high power output in a smaller form factor.
- Cable Quality: A high-quality USB-C to USB-C cable that supports 5A is essential for Super Fast Charging 2.0. Look for cables that are PD 3.0 certified and rated for 5A or higher.
