Why Most Chargers Only Give Your S25 Ultra 25W

The Samsung Galaxy S25 Ultra supports 45W Super Fast Charging 2.0, but there's a catch that trips up most buyers: standard USB-C PD chargers cap at 25W on Samsung phones, regardless of their wattage rating.

The PPS Requirement

Samsung requires PPS (Programmable Power Supply) for 45W charging. PPS is an extension of USB Power Delivery that allows the charger to adjust voltage in tiny 20mV steps between 3.3V and 21V. Without PPS, Samsung's charge controller falls back to the standard 25W PD profile.

How to Check If Your Charger Supports PPS

Check Your Phone

Settings > Battery > Charging. If it says "Super Fast Charging 2.0", your charger has PPS.

Check the Charger

Look for "PPS" or "Programmable Power Supply" in the specs. Standard "PD" alone is not enough.

Quick Test

Plug in and check if the notification says "Super Fast Charging" (25W) or "Super Fast Charging 2.0" (45W).

Samsung Galaxy Charging Speeds Compared

Every Samsung Galaxy phone needs PPS to unlock its maximum wired charging speed.

  • International plug adapters — UK, EU, US, AU included
  • Dual USB-C ports for phone + second device

  • Perfect for Samsung users who travel internationally
  • CE/UKCA certified

At just £19.99, the SmartGear Travel Charger is a steal. It delivers 45W PPS for Samsung Super Fast Charging and comes with international plug adapters. Ideal if you travel frequently or want a spare charger for the office.

What to Look for in a Samsung S25 Ultra Charger

PPS Support (Essential)

Without PPS, your charger maxes out at 25W on Samsung phones. PPS is not the same as PD — look for "PPS" or "Programmable Power Supply" explicitly in the charger specs. All three chargers we recommend above include PPS.

45W or Higher Wattage

The S25 Ultra draws up to 45W. A 65W charger with PPS is ideal — it delivers 45W to the phone and has headroom for a second port. A 25W PPS charger works but charges slower than the phone's maximum.

GaN Technology

GaN (Gallium Nitride) chargers are up to 40% smaller than silicon equivalents. A 65W GaN charger is roughly the size of Samsung's 25W charger. Look for GaN III for the latest generation.

UK 3-Pin Plug

Make sure the charger has a proper UK 3-pin plug — not a EU adapter with a converter. All our picks come with native UK plugs. For travel, the SmartGear Travel Charger includes international adapters.

Why Not Just Buy from Amazon?

Amazon UK is flooded with chargers from unknown sellers. Many are grey-market imports without proper UKCA certification — meaning they haven't been independently tested for UK mains safety. Some lack the correct 56kΩ pull-up resistor, risking damage to your phone or laptop. When something goes wrong, the 3rd-party seller has often disappeared.

Amazon Marketplace Risks

  • No UK plug: Grey-market imports with EU/US plugs — need adapter
  • Uncertified: No UKCA mark — unknown safety testing standards
  • Mixed bins: Commingled inventory mixes genuine and counterfeit stock
  • No recourse: 3rd-party sellers vanish after complaints or warranty claims
  • Fake reviews: Fake reviews inflate ratings — hard to trust 4.5★ scores
  • FBA ≠ safe: "Fulfilled by Amazon" doesn't mean Amazon tested it

SmartGear Outlet Guarantee

  • CE/UKCA certified: Every product independently tested for UK electrical safety
  • UK warehouse: Ships from our UK warehouse — correct UK 3-pin plug included
  • Free delivery: Free delivery to any UK address, every order, no minimum
  • 30-day returns: 30-day no-questions-asked returns to our UK address
  • UK support: Real UK support team — email, phone, or live chat
  • No middleman: Same products, better price — we cut out the Amazon middleman

The bottom line: Amazon is great for books and batteries. For mains-powered electronics that plug into your wall, buy from a UK specialist who stands behind every product.

Samsung S25 Ultra Charger FAQs

Common questions about Samsung S25 Ultra chargers, 45W PPS charging, and Super Fast Charging 2.0.

Does the Samsung Galaxy S25 Ultra come with a charger?
No. Samsung stopped including chargers in the box starting with the Galaxy S21 series. The S25 Ultra box contains only the phone, a USB-C to USB-C cable, and documentation. You need to buy a 45W PPS charger separately to get the fastest charging speeds.
What watt charger does the Samsung S25 Ultra need?
The Samsung Galaxy S25 Ultra supports up to 45W wired charging, but the charger must support USB PD 3.0 with PPS (Programmable Power Supply). Without PPS, the phone caps at 25W even if the charger is rated for 65W or 100W. A 45W or 65W charger with PPS is the minimum for full-speed Super Fast Charging 2.0.
Why does my Samsung S25 Ultra only charge at 25W?
Your charger likely lacks PPS (Programmable Power Supply) support. Standard USB-C PD chargers without PPS are limited to 25W on Samsung phones. PPS allows the charger to dynamically adjust voltage in 20mV steps (3.3V–21V), which Samsung requires for 45W charging. Check your charger specs — it must explicitly list PPS or "Super Fast Charging 2.0" compatibility.
Can I use a 65W charger with my Samsung Galaxy S25 Ultra?
Yes, and it is actually the best option. A 65W GaN charger with PPS will deliver the full 45W to your S25 Ultra and still have power left for a second device on the other port. The phone's charge controller negotiates only the wattage it needs, so a higher-rated charger is perfectly safe. The SmartGear 65W GaN delivers verified 45W PPS to Samsung phones.
How fast does the Samsung S25 Ultra charge from 0 to 100%?
With a proper 45W PPS charger: 0 to 50% in approximately 22 minutes, 0 to 100% in about 62 minutes. With a 25W charger (no PPS): 0 to 50% in approximately 30 minutes, 0 to 100% in about 75 minutes. The difference is most noticeable in the first 50%, where 45W PPS is significantly faster. After 80%, all chargers slow down due to Samsung's battery protection algorithms.
Does the Samsung S25 Ultra support wireless charging?
Yes. The Galaxy S25 Ultra supports Qi2 wireless charging at up to 15W and Wireless PowerShare (reverse wireless charging) at 4.5W. However, wireless charging is 3x slower than wired 45W charging. For overnight charging, wireless is convenient. For quick top-ups during the day, a 45W PPS wired charger is always the better choice.
