Real vs Fake Adapter Test for Galaxy S23, S24, S25 — Full Guide
Published: May 2026 | tapsvision.in
If you just bought a Samsung Galaxy S23, S24, or S25 — or any premium Samsung smartphone — you already know that Samsung does not include a charger in the box anymore.
So the first thing most people do is go online or to a local shop to buy one. And this is exactly where the problem starts.
The market is full of fake Samsung 25W chargers that look almost identical to the original. Same colour. Same shape. Even similar packaging. But they can damage your phone battery over time — and in some cases, they can be a safety risk.
In this video and blog, I unboxed the official Samsung 25W charger and tested it. Here is everything you need to know before you buy.
Samsung 25W Charger Unboxing — What Is Inside the Box?
The official Samsung 25W adapter comes in a simple, no-frills box. Here is what you get:
- Samsung 25W Power Adapter (the charger brick)
- Leaflet / documentation — nothing else
- No cable included — you need to buy a USB Type-C cable separately
That last point catches a lot of people off guard. The box contains only the adapter. If you do not already have a Samsung USB-C cable, you will need to buy one.
Price — How Much Does the Original Cost?
The MRP printed on the box is around ₹1,700. However, on the official Samsung store and authorised sellers, it is typically available for around ₹1,400.
If someone is selling you a Samsung 25W charger for ₹300–₹600, it is almost certainly fake. The price itself is one of the biggest red flags.
Official price: ₹1,400 – ₹1,700 | Anything significantly cheaper = likely fake
Samsung 25W Charger — Full Specifications
Here is what is printed on the back of the official adapter:
- Output: 25W maximum
- Charging standard: PD 3.0 / PPS (Programmable Power Supply)
- Low standby power consumption
- USB Type-C output port
- BIS certified (IS 13252) — mandatory for India
The BIS certification mark is one of the first things to check. Every original Samsung charger sold in India must carry a BIS (Bureau of Indian Standards) certification number. Fake chargers either skip this entirely or print a fake number.
How to Check if Your Samsung 25W Charger is Original or Fake
This is the question most people are actually searching for — and it is the most important part of this blog. Here are the exact things to check:
Step 1 — Check the BIS Certification Number
Every original Samsung charger has a BIS registration number printed on it. You can verify this number on the BIS India website. Fake chargers will either have no number or a number that does not match any registered product.
Step 2 — Check the Build Quality and Finish
The original charger has a matte, premium plastic finish. It feels solid and slightly heavy. Fake ones feel lighter, have a slightly glossy or cheap plastic texture, and the Samsung logo may look slightly blurry or off-centre.
Step 3 — Check the USB-C Port
The original adapter has a clean, tight USB-C port. When you plug in a cable, it should click in smoothly and feel secure. Fake chargers often have a loose port where the cable wobbles.
Step 4 — Check the Charging Speed on Your Phone
When you connect an original Samsung 25W charger to a compatible phone, your phone should show ‘Super Fast Charging’ in the status bar. If it shows normal charging only — the charger is likely not original.
Step 5 — Check the Price and Seller
Only buy from Samsung’s official website, Samsung SmartPlaza stores, or authorised sellers on Amazon and Flipkart. Avoid third-party sellers with unusually low prices.
Quick checklist: BIS mark ✓ | Premium build ✓ | Tight USB-C port ✓ | Super Fast Charging on screen ✓ | Bought from authorised seller ✓
How Fast Does the Samsung 25W Charger Actually Charge?
In real-world usage, the Samsung 25W adapter charges a Galaxy S23 or S24 from 0 to 100% in approximately 1 hour 15 minutes to 1 hour 20 minutes.
On a budget Samsung phone like the Galaxy M13 or M14, charging times will differ since those phones support lower wattage. But even on budget phones, this adapter works fine — it just adjusts the output automatically.
The PPS (Programmable Power Supply) technology in this charger means it intelligently adjusts voltage and current based on what your phone needs. This is why it is safe to use with multiple Samsung models.
Where to Buy the Original Samsung 25W Charger
After buying expensive Samsung phones, the last thing you want is to damage the battery with a cheap fake charger. Always buy from:
- Samsung official website — samsung.com/in
- Samsung SmartPlaza stores near you
- Amazon India — verified authorised sellers only
- Flipkart — look for Samsung Fulfilled listings
Avoid: local mobile accessory shops, unknown online sellers, and anything priced below ₹900.

FAQ — Samsung 25W Charger
Is the Samsung 25W charger compatible with all Samsung phones?
Yes, it works with all Samsung USB-C phones. However, Super Fast Charging (25W) is only available on phones that support it — like the Galaxy S21, S22, S23, S24, and S25 series. Budget models will charge at a lower wattage automatically.
Can I use the Samsung 25W charger with an iPhone?
Yes, iPhones with USB-C (iPhone 15 and later) can use this charger. Older iPhones with Lightning ports cannot.
Does Samsung include a 25W charger in the box?
No. Samsung has removed chargers from the box since the Galaxy S21 series. You need to buy the charger separately.
Is it safe to use a third-party 25W charger for Samsung?
Technically it works, but there is a risk. Non-original chargers may not support PPS properly, which can lead to slower charging speeds, battery degradation over time, or in extreme cases, overheating.
How do I identify a fake Samsung charger?
Check the BIS certification number, the build quality and weight, the USB-C port tightness, and whether your phone shows Super Fast Charging when connected. If any of these fail, the charger is likely fake.
Final Thoughts
The Samsung 25W charger is genuinely good — fast, safe, and built well. At ₹1,400, it is not cheap, but given how expensive these phones are, it makes no sense to risk the battery with a ₹300 fake.
Buy original. Charge safe. Your battery will thank you in the long run.
If this article helped you identify an original Samsung charger or avoid a fake one, share it with someone who just bought a new Samsung phone. They probably need this.
