Quick answer: Which charger for Samsung Galaxy S25 Ultra? The best choice is Samsung 45W Power Adapter EP-T4511 45 W - about 100% of the maximum charging speed (phone: max 45 W). On a regular USB-PD charger the phone is limited to about 23 W.
Which charger for Samsung Galaxy S25 Ultra? Power specs and what you actually need
If you are wondering which charger for Samsung Galaxy S25 Ultra to pick up, the short answer is straightforward: you need an adapter that supports USB Power Delivery with PPS (Programmable Power Supply) and can deliver up to 45W. PPS is a communication protocol that lets the phone dynamically adjust the voltage during the session, which is how Samsung unlocks its full charging rate.
Samsung includes a USB-C cable in the box, but there is no wall plug. If you plug the phone into an older USB PD adapter that lacks PPS, the Galaxy S25 Ultra will still charge normally, but it settles on a fixed voltage path capped at roughly 23W. To hit the full 45W potential, the charger must support a PPS output window reaching up to 16V at 3A.
This guide is for anyone who just unpacked their Galaxy S25 Ultra and wants to know whether the plug sitting in their desk drawer is enough, or which model is worth buying for the fastest top-up.
Specs and charging
The key Samsung Galaxy S25 Ultra specs that matter when choosing a charger:
- Battery: 5000 mAh, litowo-jonowa
- Wired charging: 45 W (Super Fast Charging 2.0 (USB PD PPS))
- On a standard USB PD charger: ~23 W
- Wireless charging: 15 W (Qi (Fast Wireless Charging 2.0))
- Reverse charging: 4.5 W
Can you reuse an old plug from your drawer?
Before spending extra money on a brand new adapter, look at the small text printed on the plugs you already own. You do not need to decipher every number, but you should look for the mentions of "PD" or "PPS" and check the output wattage.
- Old Samsung 25W charger (like the EP-T2510): It supports PPS and provides around 20W to 24.8W to this phone. It will not hit the maximum 45W ceiling, but it remains a solid, dependable backup option.
- A USB-C laptop brick (45W, 65W, or higher): If it supports the USB PD PPS standard with up to 16V and 3A, it will charge your phone at full 45W speed. If it only supports standard USB PD without PPS, the phone safely charges at around 23W.
- A standard 20W adapter (such as an Apple iPhone plug): It relies on fixed USB PD voltages without PPS. The S25 Ultra will pull around 20W, which is perfectly safe but noticeably slower.
- An older USB-A charger: Adapters using standard rectangular USB-A ports without fast charging protocols will typically provide only 5W to 10W. That will take several hours to fill the battery.
Fun fact: The PPS extension was added to the USB Power Delivery specification back in 2017 to allow smartphones and chargers to negotiate voltage dynamically in tiny increments, significantly reducing heat buildup inside the phone battery.
Real-world top-up times: what the numbers mean daily
Having 45W capability does not mean the phone takes 45W from zero to one hundred percent. The highest intake happens early in the cycle, making a high-wattage PPS charger especially practical when you need a quick boost before heading out.
In independent testing by GSMArena, the Galaxy S25 Ultra reached 41% in just 15 minutes and 72% in 30 minutes when paired with a compatible 45W PPS charger. Samsung officially advertises roughly 65% in 30 minutes. A full top-up to 100% took 59 minutes in the GSMArena test. In a separate test by ChargerLAB with a 65W charger, a complete charge finished in 1 hour and 22 minutes.
The included USB-C cable in the box is rated for 3A and is completely fine for this setup. Both GSMArena and ChargerLAB measured real peak power levels of around 39W to 41W using a 45W PPS charger with the bundled cable. You do not need an oversized aftermarket cable to achieve peak speeds.
Choosing the right wall adapter: top picks for your setup
If you want guaranteed full performance without checking specs, the official Samsung 45W Power Adapter EP-T4511 is the benchmark choice. It matches the phone's PPS profile exactly, delivering around 45W and unlocking 100% of the real maximum charging speed.
For the most affordable way to hit full speed, the Google 45W USB-C Charger also delivers the full 45W to this phone. It handles the required PPS profile properly while keeping the overall cost down.
If you prefer a single travel plug for both your phone and a laptop, multi-port models like the UGREEN Nexode 65W and the Anker 735 (Nano II 65W) are great options. Both provide around 45W to the Galaxy S25 Ultra while leaving enough headroom to power other devices simultaneously.

| Samsung 65W Power Adapter Trio EP-T6530 | 65 W | 100% |
| Google 45W USB-C Charger | 45 W | 100% |
| UGREEN Nexode 65W | 65 W | 100% |
| Anker 735 (Nano II 65W) | 65 W | 100% |

Technical pitfalls: why a powerful adapter might charge slowly
A higher wattage printed on the adapter box does not automatically mean faster charging for your Galaxy S25 Ultra. Here are the specific bottlenecks to keep in mind:
- Missing PPS support: A 65W or 100W laptop charger that only supports standard fixed-voltage USB PD will fall back to the phone's non-PPS charging path. In that case, the S25 Ultra pulls roughly 23W, regardless of how much power the charger has on reserve.
- Incompatible PPS current profile: The Galaxy S25 Ultra requests up to 16V at 3A. If a third-party PPS charger only offers high current at lower voltages (like 11V at 3A), it cannot supply the full 45W to this specific handset.
- Proprietary protocols from other brands: Adapters built for brands like OnePlus, Vivo, or Xiaomi rely on their own proprietary charging standards. Connected to the Galaxy S25 Ultra, they will drop to basic protocols and typically deliver only between 10W and 23W.
Common questions about Galaxy S25 Ultra power and charging
Which charger for Samsung Galaxy S25 Ultra delivers maximum speed?
To reach the full 45W speed, you need an adapter that supports USB Power Delivery with PPS and covers a profile up to 16V at 3A. The Samsung 45W Power Adapter EP-T4511 or the Google 45W USB-C Charger are prime examples that deliver the full 45W rate.
Is a charger included in the Samsung Galaxy S25 Ultra box?
No, Samsung does not include a wall adapter in the box. You will only find the phone itself and a standard USB-C to USB-C charging cable.
Can I use my USB-C laptop charger with the Galaxy S25 Ultra?
Yes, you can safely use it. If the laptop charger supports the USB PD PPS standard, the phone can reach up to 45W; if it only supports standard USB PD without PPS, the Galaxy S25 Ultra will charge at roughly 23W.
Do I need to buy a special 5A cable to get 45W charging?
No, the 3A USB-C cable included in the box is sufficient. Test measurements from GSMArena and ChargerLAB show real power peaks of 39W to 41W using a 45W PPS charger with the standard 3A cable.
What happens if I connect a standard USB-C charger without PPS?
The phone will use its standard USB PD charging path, which is capped at around 23W. This is a completely standard, stable charging mode, though it will take longer to fill the battery than a 45W PPS charger.
