If you are one of those users who spent a lot of money and bought the latest Samsung flagship, you must be familiar with this scene; you connect your old phone to your old power bank with great enthusiasm, but its charging speed is like a turtle and does not bother you! Where is the problem? Why is the power bank that says fast charging on the box, can’t charge your Samsung phone quickly? The answer is simple; new Samsung phones, especially the flagship Galaxy ones, are not friends with every power bank. They have a special language for charging and if your power bank does not know that language, your phone will not receive it and will charge at the slowest possible speed. In this article, we are going to reveal the secret of this technology to you and introduce the best power bank for Samsung phones that can be found on the market so that you never have to worry about your phone running out of power again.
The secret of Samsung’s fast charging; From super fast charging to PPS!
Before we get into the best power bank brands for Samsung phones, let’s first understand what these new phones are all about. Samsung has had a few different fast charging technologies in recent years, from the 15W Adaptive Fast Charging found on older phones to the latest generation, Super Fast Charging, which is a whole other world of speed. If you want to buy a power bank that won’t cost you a fortune, you need to know these terms like the back of your hand.
What does 25W and 45W Super Fast Charging mean?
When you buy a Samsung phone these days, it’s likely to support one of two fast charging standards:
- 25W Super Fast Charging: This standard is found on most new Samsung phones, from popular mid-range phones like the Galaxy A55 and A35 to flagships like the Galaxy S24 and foldable phones like the Z Flip and Z Fold. This technology can charge your phone’s battery to 50% in about 30 minutes, which is great for everyday use.
- Super Fast Charging 2.0 with 45W: This is another super-fast one and is designed specifically for Samsung’s high-end flagships like the Galaxy S24 Ultra and S25 Ultra. With this technology, you can fully charge the giant battery of these phones in less than an hour. It’s interesting to know that the difference in speed between a 25W and 45W charger in the real world, especially in the final minutes of charging, is not very much and may save you about 7 to 10 minutes in total, but for those in a hurry, those few minutes are worth it.
To use these speeds, you must have enabled the Fast Charging and Super Fast Charging options in your phone’s settings (Battery and device care section).
PPS: The key to super fast charging!
Now, we come to the most important part of the story, which 90% of users are unaware of and which makes them make the wrong choice. Don’t think that any power bank that says 45W can charge your S24 Ultra at maximum speed. That’s not the case! Samsung’s Super Fast Charging technology requires a special protocol called PPS or Programmable Power Supply to work. This protocol is actually an advanced part of the famous USB Power Delivery (PD) 3.0 standard.
Let me put it simply; think of regular chargers as ready-made clothes in the store; they only come in a few standard sizes (say, 5V, 9V, or 12V) and your phone has to choose one. But PPS works like a professional tailor. When you connect your phone to a PPS-equipped power bank, the two talk to each other, and the power bank produces exactly the voltage and current that your phone’s battery needs at that moment (say, 6.4V and 2.75A).Xiaomi Pad 7 Pro Tablet Review
This precise, instantaneous adjustment has several great benefits:
- Faster charging speed: Because energy is transferred in the most efficient way possible, charging speeds are maximized.
- Less heat: The biggest enemy of a battery is heat. By preventing energy loss, PPS keeps your phone and power bank from getting too hot.
- Extended battery life: Less heat and more efficient charging means less stress on the battery cells, which means your phone’s battery will last longer.
So, when buying a power bank for your Samsung phone, don’t just look at the wattage. The most important thing to look for is support for the PPS protocol. If you buy a 100W power bank that doesn’t have PPS, your Samsung phone will probably charge at the same 15 or 18W rate, and you’ll be wasting your money on power you can’t use. This is the same trap that many people fall into.
| Criterion / Feature | Explanation & Key Points |
|---|---|
| Main Cause of Slow Charging | Older power banks do not support the PPS protocol and are therefore incompatible with Samsung’s fast charging standards. |
| Samsung’s Fast Charging Standards | – Super Fast Charging 25W: For models like Galaxy S24, Z Flip/Fold, A55/A35. – Super Fast Charging 2.0 (45W): For high-end flagships like the Galaxy S24 Ultra. |
| Most Important Technology (The Master Key) | PPS (Programmable Power Supply); an advanced protocol within USB Power Delivery (PD) 3.0 that is essential for Samsung’s fast charging. |
| How PPS Works | The power bank and phone communicate intelligently in real-time to precisely and optimally adjust voltage and current for the battery. |
| Benefits of PPS | 1. Maximum charging speed 2. Reduced heat generation 3. Increased battery lifespan due to reduced stress and heat. |
| Important Warning | Buying high-power banks (e.g., 100W) that lack PPS will only result in slow charging (15-18W) and is a waste of money. |
| Final Buying Tip | When purchasing, look for the term PPS or Programmable Power Supply in the power bank’s technical specifications, not just the “Watt” number. |
