If you are shopping for a premium adapter for your Samsung Galaxy S24 Ultra or S23 Ultra in local Pakistani tech hubs like Hafeez Center or Saddar, you have likely encountered a confusing marketing term. Many shopkeepers confidently hand over a boxed adapter and highlight a specific label to prove its authenticity: “NFC Supported Fast Charging.”
For the average consumer, this sounds like a high-tech upgrade. You might wonder if your charger is going to wirelessly communicate with your smartphone to deliver power, or if Near Field Communication (NFC) is the secret behind Samsung’s 45W charging speeds.
In a market saturated with master copies and dangerous replicas, understanding what this term actually means is critical to protecting your expensive flagship phone from electrical damage and WAPDA voltage surges.
NFC (Near Field Communication) does not physically charge your phone. In the context of Samsung accessories, NFC allows supported devices to communicate wirelessly for authentication and smart functionality. However, local sellers in Pakistan often use the “NFC Supported” label on charger packaging as a gimmick to claim originality. True Samsung 45W speed relies entirely on Super Fast Charging 2.0 (SFC 2.0) and Programmable Power Supply (PPS) protocols through a wired Type-C connection, not NFC radio waves.
Let’s decode the marketing jargon, explain how Samsung’s high-speed charging actually works, and show you exactly how to verify a genuine 45W adapter.
The Myth vs. Reality of NFC in Samsung Chargers
To clear up the confusion, we have to separate radio wave technology from electrical power delivery.
What Does NFC Actually Do?
NFC is a short-range wireless technology. You use it every day when you tap a credit card on a payment terminal or instantly pair wireless earbuds to your phone. In the Samsung ecosystem, NFC is heavily used in official smart accessories. For example, Samsung’s Smart LED View Covers use NFC chips to authenticate the case and draw a tiny amount of wireless power to light up the display.
Why is NFC Mentioned on Charger Boxes?
A lot of buyers get confused when they see Samsung chargers mentioning NFC support. In Pakistan’s mobile accessories market, the “NFC-supported” label has become a localized myth. Because official Samsung accessories utilize NFC for digital authentication, some buyers look for the NFC mention on the box as a strict sign of originality.
Counterfeit manufacturers quickly realized this. Today, some fake products now copy packaging claims as well, slapping “NFC Supported” on cheap, hollow boxes to trick unsuspecting buyers. An NFC label on a cardboard box does not automatically confirm originality. Power is delivered through copper pins, not NFC fields.
The Real Tech: Super Fast Charging 2.0 (SFC 2.0)
If NFC isn’t responsible for fast charging, what is? The true magic inside the official Samsung 45W charger (Model: EP-T4510) is a protocol called Super Fast Charging 2.0.
Samsung’s SFC 2.0 operates on the USB Power Delivery (USB-PD) 3.0 standard, paired strictly with Programmable Power Supply (PPS) technology.
How PPS Protects Your Battery
Standard fast chargers pump electricity using fixed, rigid voltage steps (e.g., jumping from 5V to 9V). This rigid conversion creates massive internal resistance, which manifests as heat. Heat is the ultimate killer of lithium-ion batteries, especially during 40°C Pakistani summer afternoons.
PPS changes the entire equation. A PPS-certified Samsung 45W charger actively talks to your smartphone’s Power Management IC (PMIC). Instead of rigid steps, PPS adjusts the voltage dynamically in microscopic increments in real-time based on the battery’s current temperature and percentage.
- 0% to 50% (The Sprint): The charger delivers maximum wattage to rapidly revive a dead phone.
- 50% to 80% (The Taper): The phone instructs the charger to slowly drop the voltage, preventing the battery from overheating.
- 80% to 100% (The Trickle): Power is severely throttled to a slow 15W trickle to protect the chemical integrity of the battery layers.
This intelligent thermal management is why a genuine 45W charger can rapidly charge your device without causing the battery to swell or catch fire.
The 5A Cable Requirement: The Hidden Bottleneck
One of the most common complaints we receive at TechTouch.pk is from users who buy a 45W brick, plug it in, and notice their phone only displays the standard “Super Fast Charging” (25W) animation instead of the coveted “Super Fast Charging 2.0” notification.
The culprit is almost always the wire.
Power equals Voltage multiplied by Current (Amps). To achieve 45W, the charger must push up to 5 Amps of current. A standard Type-C cable (like the one that comes in the box with standard phones) is physically limited to a maximum of 3 Amps.
If you attempt to push 45W through a standard 3A wire, the cable could easily melt. To prevent this, Samsung 45W chargers require a specialized 5A E-Marked Type-C to Type-C cable.
- The E-Marker Chip: This is a microscopic digital chip inside the cable’s connector. When you plug the charger into the wall, it pings the cable. If the E-Marker chip replies, “I am a 5A cable,” the charger authorizes the 45W flow.
- The Failsafe: If you use a cheap market cable without an E-Marker chip, the charger immediately defaults to 25W to prevent a fire hazard.
How to Genuinely Verify an Original Samsung 45W Charger (EP-T4510)
Because the “NFC” box label is easily faked, you must rely on objective, physical hardware tests to identify a genuine Samsung 45W adapter. Do not compromise; fake chargers lack Metal Oxide Varistors (MOVs) and isolation transformers, leaving your logic board completely unprotected against WAPDA power grid surges.
Use this professional inspection matrix before you make a purchase:
| Inspection Feature | Genuine Samsung 45W (EP-T4510) | Counterfeit Market Replicas |
| Physical Weight | Extremely dense, weighing approximately 84g to 86g due to copper shielding. | Very light (under 75g) or artificially heavy with loose iron weights that rattle. |
| Model Number Marking | Laser-engraved directly into the plastic casing (EP-T4510). | Frequently uses a cheap sticker label or adds extra letters (e.g., EP-T4510X). |
| Cable Markings | Included cable features “5A” and “E-Mark” faintly laser-etched on the connectors. | Missing 5A text, or uses generic thick nylon braiding to mimic quality. |
| Edge Finishing | Sharp, precise 0.5mm chamfered edges with a premium matte black texture. | Rounded, uneven edges with a slightly glossy or grainy plastic feel. |
| Thermal Performance | Reaches a warm, stable temperature (approx. 40°C) during heavy charging. | Exceeds 60°C, becoming dangerously hot to the touch after 10 minutes. |
Which Devices Actually Support 45W SFC 2.0?
Another massive trap in the local market is the assumption that any modern Samsung phone can utilize 45W speeds. Buying a 45W charger for a phone that maxes out at 25W will not damage the device, but it is a complete waste of money, as the phone will simply throttle the adapter down to 25W.
Devices that fully support 45W Super Fast Charging 2.0:
- Samsung Galaxy S24 Ultra & S24+
- Samsung Galaxy S23 Ultra & S23+
- Samsung Galaxy S22 Ultra & S22+
- Samsung Galaxy Tab S9 and Tab S8 Ultra series
Devices capped at 25W (Do NOT buy a 45W charger for these):
- Samsung Galaxy S24 (Base Model)
- Samsung Galaxy S23 & S22 (Base Models)
- Samsung Galaxy Z Fold 5 & Z Flip 5
- Samsung Galaxy A-Series (A55, A54, A34, etc.)

Final Verdict: Protect Your Logic Board
The term “NFC Supported Fast Charging” is a localized marketing distraction. When evaluating power accessories, you should ignore the radio wave buzzwords and focus entirely on USB-PD compliance, PPS thermal management, and the inclusion of a 5A E-Marked cable.
Using a counterfeit 45W charger in Pakistan’s volatile electrical environment is a gamble you will eventually lose. Counterfeits frequently fail to negotiate voltage properly, misreport their power data objects, and lack essential overvoltage protection.
If you own a premium Galaxy Ultra device, do not bottleneck its performance or risk its motherboard with unverified hardware. Stick to authentic, lab-tested gear to ensure you safely hit that 0-65% charge in under 30 minutes, every single time.
Frequently Asked Questions
Can I use a 45W Samsung charger on my 25W Galaxy A55?
Yes, it is entirely safe. Because original Samsung chargers use the USB Power Delivery protocol, the charger and the phone negotiate power before charging begins. The adapter will simply act as a 25W charger, ensuring your Galaxy A-series phone does not overheat.
How do I know if Super Fast Charging 2.0 is working?
When you plug in an authentic 45W charger with the correct 5A cable, your Samsung phone screen will briefly display a distinctive teal/blue charging ring animation, and the text “Super Fast Charging 2.0” will appear on the lock screen. If it only says “Super Fast Charging” with a green ring, you are only receiving 25W.
Will fast charging my Samsung to 100% every day ruin the battery?
Modern Samsung PMIC (Power Management IC) chips are highly intelligent and actively prevent overcharging. However, holding lithium-ion batteries at exactly 100% capacity for hours does induce chemical stress. To maximize your battery’s multi-year lifespan, utilize Samsung’s built-in “Protect Battery” feature, which limits the maximum daily charge to 85% or 80%
