When I started searching for the best charger for my Samsung Galaxy S22, I assumed it would be a straightforward task. The market is filled with 25W and 45W chargers claiming compatibility, and I thought wattage alone determined charging speed. But after testing multiple chargers and digging into USB Power Delivery (PD) and Programmable Power Supply (PPS), I realised why so many chargers fail to deliver Samsung’s promised super fast charging.
The first charger I tried was a basic 25W adapter without USB PD or PPS support. These chargers rely on Samsung’s older Adaptive Fast Charging protocol. While they technically work with the Galaxy S22, they only deliver around 15W-18W. There was no “super fast charging” text on the lock screen, and charging from 0 to 100% took almost 90 minutes. For someone needing quick top ups between tasks, this was too slow.
Next, I tested a 25W USB PD charger without PPS. This option supports fixed voltage levels like 5V, 9V, and 15V. The S22 can draw 9V at 2.77A (~25W), but without PPS, the phone regulates voltage internally. This creates additional heat, potential throttling, and slightly slower charging. Charging times improved to around 85 minutes but still lagged behind Samsung’s official charger.
Finally, I tried a charger supporting both USB PD and PPS. This changed everything. PPS allows dynamic voltage and current adjustments in fine steps, such as 3.3V-11V. The Galaxy S22 uses this feature to request optimal power delivery, charging more efficiently and with less heat. With a PD+PPS charger, my phone charged from 0-50% in about 25 minutes and reached 100% in approximately 70 minutes - the true “super fast charging” experience.
| Charger type | Works with S22? | Charging speed | Super fast charging? | Approx 0-100% time |
|---|---|---|---|---|
| 25W charger (no PD or PPS) | Yes | 15W-18W | No | ~90 minutes |
| 25W USB PD charger (no PPS) | Yes | 18W-22W | No | ~85 minutes |
| 25W USB PD charger with PPS | Yes | Full 25W | Yes | ~70 minutes |
| 45W USB PD charger (no PPS) | Yes | S22 limited to ~22W | No | ~85 minutes |
| 45W USB PD charger with PPS | Yes | S22 limited to 25W | Yes (S22+ only) | ~70 minutes |
On Amazon and Flipkart, many cheap chargers advertise 25W or 45W output but lack PPS support. Without PPS, even a 45W charger won’t trigger “super fast charging” on the Samsung Galaxy S22. Instead, it defaults to standard PD profiles, forcing the phone to handle voltage regulation. This leads to heat build up and slower charging.
Always check the charger specs carefully. Look for explicit PPS support like: PPS: 3.3V-11V⎓3A and ensure it supports USB PD 3.0 or higher. This is the only way to get the fastest, most efficient charging for your Galaxy S22.
While exploring chargers, I came across GaN (Gallium Nitride) chargers. GaN technology allows higher efficiency, better thermal management, and significantly smaller designs compared to traditional silicon chargers.
But remember: GaN is about hardware design, not charging protocols. A GaN charger without PD and PPS won’t give you Samsung’s “super fast charging.” You still need PD 3.0+ and PPS support.
For the Samsung Galaxy S22, don’t rely on wattage ratings alone. Ensure your charger supports:
This combination delivers the full super fast charging experience Samsung promises. I settled on a 25W GaN PD+PPS charger, which cost slightly more than generic adapters but was worth every rupee. It charged my phone from 0-50% in just 25 minutes and gave me confidence in its efficiency and thermal management.
For Galaxy S22+ and S22 Ultra users, a 45W GaN PD+PPS charger makes sense to unlock Super Fast Charging 2.0.
Investing in the right charger means saving time every single day and for a phone that powers everything from meetings to app testing, that’s a trade off I’ll happily make.
