Samsung 25W vs 45W Charger Pakistan: Which One You Need, and When the Cheaper Option Wins

The Samsung 25W adapter costs PKR 2,840 and the 45W costs PKR 4,200 at AvaNext as of September 2026. For most Galaxy A-series phones sold in Pakistan — the A35, A55, A25 — the 25W is the correct charger. The 45W adds nothing on those models. You are paying PKR 1,360 extra to charge at exactly the same speed.

If you have a Galaxy S22, S23, S24, or S25, the situation reverses: the 45W is the right adapter, and the 25W will undercharge your phone by roughly 20W during the critical first half-hour. This guide breaks down which model gets which charger, what the real speed difference looks like during a load-shedding window, and how to tell a fake from an original at the door when the COD rider arrives.

What is the actual difference between the Samsung 25W and 45W charger?

The Samsung 25W adapter (model EP-TA800) outputs USB-C at up to 25W using USB Power Delivery. The Samsung 45W adapter (model EP-TA845) adds a second protocol: Programmable Power Supply (PPS), which allows the charger and phone to negotiate the most efficient voltage-current combination at each stage of charging.

PPS is what makes the speed gap meaningful. On a Galaxy S24, the adapter delivers up to 45W during the 0-50% charge range — the phase where the battery accepts maximum current. Once the battery crosses 50%, both adapters slow down deliberately to protect battery chemistry. The speed difference between 25W and 45W is concentrated in that first 30 minutes.

In practice, on a Galaxy S24 starting from a depleted battery: the 45W adapter reaches approximately 50% in 30 minutes. The 25W adapter takes 45-50 minutes to reach the same point. That 15-20 minute gap matters when load shedding gives you a one-hour electricity window and you need to leave.

One more constraint: a USB-C cable rated for 5A is required to reach the full 45W. The cable bundled with Samsung's original EP-T4510 kit is rated for it. A generic PKR 200 cable from a roadside stall typically is not, and it will cap delivery at 25W even with the 45W adapter in the socket.

Which Samsung Galaxy phones sold in Pakistan actually support 45W?

Samsung's charging compatibility is genuinely confusing, because the company does not consistently label charging speeds on Pakistani retail packaging, and because the S21 Ultra also caps at 25W — despite being the flagship. The table below covers the phones most commonly sold in Pakistan:

The S21 range trips people up regularly. Both the S21 standard and the S21 Ultra top out at 25W — not 45W, despite the Ultra being Samsung's flagship that year. Only the S22 series introduced 45W PPS as a standard feature. If you have any S21 variant, save the PKR 1,360 and buy the 25W.

The Samsung 25W PD Adapter is available at AvaNext for PKR 2,840 with Cash on Delivery nationwide. If you have an A-series phone and a retailer tells you the 45W is "better" without specifying why, that is either misinformation or a sales push.

How to identify a fake Samsung charger in Pakistan

Both Samsung adapters are heavily counterfeited. Copies appear in Saddar Mobile Market, Hafeez Centre in Lahore, and across Daraz listings that claim "original Samsung" at prices that make originals impossible to stock. Here are the checks that reliably distinguish an original from a copy:

• Model number on the adapter body. The genuine 25W is marked EP-TA800. The genuine 45W is marked EP-TA845. On an original, this text is debossed — pressed into the plastic — and crisp. On most copies, the text is raised, blurry, or carries a different model number.
• The charging notification on the phone. Connect the adapter and pull down the notification shade within 10 seconds. A genuine 45W adapter connected to a Galaxy S22 or newer should display "Super Fast Charging 2.0". If the phone shows only "Fast Charging" or plain "Charging," the adapter is not delivering 45W regardless of what the label says. A genuine 25W on a compatible phone shows "Super Fast Charging."
• Weight. Original Samsung adapters are noticeably denser than copies. The internal components are heavier. A copy typically feels lighter and sometimes flexes slightly if you press the body.
• Temperature after 10 minutes. A genuine adapter runs warm. A copy often runs either unusually hot — uncomfortable to hold — or suspiciously cool, indicating different internal circuitry.

The notification test is the fastest check available and should be the first thing you do when a COD order arrives. If "Super Fast Charging 2.0" does not appear on your S22 or newer within 10 seconds of plugging in, reject the delivery.

What do original Samsung chargers cost in Pakistan right now?

At AvaNext, as of September 2026:

• The Samsung 45W Fast Charging Adapter with original USB-C to USB-C cable — PKR 4,200, available in White and Black, Cash on Delivery across Pakistan.
• The Samsung 25W PD Adapter — PKR 2,840, Cash on Delivery nationwide.

On Daraz, listings for "original Samsung 45W" range from PKR 1,800 to PKR 6,000 for the same stated product. At PKR 1,800, the math does not work: Samsung's cost of goods alone rules out a genuine adapter at that price. At PKR 6,000 from an unverified seller with no return policy, you are overpaying for unknown provenance.

The PKR 4,200 price at AvaNext reflects genuine imported stock. COD means you pay after confirming the adapter works. If the notification test fails, do not hand over the money.

Why the right charger matters more during load shedding

Load shedding in Pakistan compresses the charging window. The difference between 25W and 45W is not just about speed in ideal conditions — it is about how much charge you recover during each electricity window.

On a Galaxy S24 at 10% battery: 90 minutes of genuine 45W charging reaches approximately 75-80%. The same 90 minutes at 25W reaches roughly 55-60%. That 15-20% gap, multiplied across several load-shedding cycles per day, is meaningful.

There is a second issue specific to Pakistan: voltage spikes when electricity is restored after an outage. Genuine Samsung adapters include surge protection built to IEC standards. Most copies circulating in the Pakistani market do not have equivalent protection. The brief over-voltage when power comes back can damage an unprotected adapter — or, with repeated exposure, degrade battery health. Battery capacity dropping to 70% in under a year is a pattern the AvaNext team at the Saddar counter sees regularly, and it almost always traces back to unverified chargers used through months of load shedding.

Frequently asked questions

Can I use a Samsung 45W charger on a Galaxy A55?

Yes, it will charge the A55 — but only at the A55's maximum supported speed of 25W. The 45W adapter does not harm the phone. It simply does not accelerate charging beyond 25W on A-series hardware. If you are buying new, the 25W at PKR 2,840 is the correct purchase.

What does "Super Fast Charging 2.0" mean on a Samsung Galaxy?

Super Fast Charging 2.0 is Samsung's name for 45W PPS-based charging, introduced on the Galaxy S22 series. It differs from the original "Super Fast Charging" label, which referred to 25W on S20 and S21 phones. If your Galaxy shows "Super Fast Charging 2.0," the adapter is delivering 45W via PPS.

Is a fake Samsung charger dangerous?

The more common risk is battery degradation, not fire — though inadequate insulation in low-quality copies does create a fire hazard. A charger delivering inconsistent voltage stresses the battery management system. Battery health dropping to 70-75% within one year of regular use is a recognised pattern with unverified chargers.

Does the Samsung 45W charger include a cable?

The adapter-only version does not include a cable. The AvaNext bundle listing for the 45W includes the original USB-C to USB-C cable rated for 5A. A generic cable not rated for 5A will cap your charging speed at 25W or lower even with the 45W adapter connected.

Which Samsung charger should I buy for a Galaxy S21 Ultra?

The Galaxy S21 Ultra supports a maximum of 25W charging. The Samsung 25W PD Adapter at PKR 2,840 is the correct purchase. The 45W PPS protocol is only beneficial from the S22 series onward.
