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:
1. Samsung 45W USB-C Super Fast Charger (Official)
Our top recommendation is Samsung’s in-house 45W USB-C charger, the official choice for the Galaxy S25 Ultra and S25+. It can charge your phone to about 68% in 30 minutes and fully charge it in just under an hour.
The charger is available on both Amazon and Samsung Store. It comes with a compatible USB-C to USB-C charging cable inside the box, so you’ll have an extra just in case.
2. Google 45W USB-C GaN Charger
Another high-quality charger from Google, this model supports USB PD 3.1 charging at up to 45W, along with PPS technology, making it fully compatible with the Galaxy S25 Ultra and S25+. This is a GaN (Gallium Nitride) charger, meaning it is super compact, generates less heat, and offers fast charging.
3. Spigen 651 65W PD 3.0 USB-C GaN Charger
The Spigen GaN 651 charger supports Power Delivery (PD) charging at up to 65W, meaning you can not only fast charge your Galaxy S25 Ultra or Plus but also power your MacBook, Galaxy Book, and other devices. This is a GaN charger—offering fast charging, less heat, and a compact size. It also comes with built-in safety features.
The charger has a folding plug, making it easy to slip into your backpack. A 6.6ft USB-C to USB-C cable is included in the package. Spigen also offers adual-port version (652)at a similar price, making it a great option if you need to charge multiple devices.
4. Anker 313 45W USB-C GaN Charger
Anker is one of my favorite third-party charger brands, known for making well-researched and safe charging adapters. The Anker 313 charger supports Super Fast Charging 2.0 and can fast charge your Galaxy S25 Ultra at a full 45W, provided you’re using a 5A cable.
With GaN technology, it’s about 30% smaller than original Samsung 45W charger. Anker has also included a total of 10 safety features, including short circuit, high voltage, and overcharge protection.
5. Belkin BoostCharge 3-Port USB-C Wall Charger with PPS 67W
This charging adapter from Belkin supports 67W of charging with Power Delivery 3.1 and PPS. It has three ports, allowing you to use one at a time to fast charge your Galaxy S25 Ultra or S25+ at full speeds, i.e., Super Fast Charging 2.0, or charge your MacBook or Galaxy Book at 67W.
When using all three ports, the top port can deliver 25W, which will charge your Samsung phone at Super Fast Charging 1.0, while the other two ports can each provide 20W. The adapter also features Belkin Smart Protect safety technology, a flat-to-wall design, and foldable prongs for easy packing.
These are five of our top picks for charging your Galaxy S25 biggie. you’re able to choose other chargers as well, but verify they support 45W or higher output via USB-C, include USB PD 3.0 or higher with PPS support, and come from a reputable brand with safety certifications.
