For B2B buyers and suppliers navigating the Samsung charger ecosystem on Alibaba.com, understanding the technical protocols behind fast charging is essential. Samsung's Super Fast Charging technology is not a proprietary standard but rather builds upon industry-wide USB Power Delivery (USB-PD) specifications with additional requirements for Programmable Power Supply (PPS) support.
The USB Power Delivery specification has evolved significantly since its introduction. USB-PD 2.0 established the baseline for USB-C charging up to 100W. USB-PD 3.0 added PPS capability, allowing fine-grained voltage control between fixed levels. The latest USB-PD 3.1 (released 2021) extends maximum power to 240W and introduces new fixed voltage levels at 28V, 36V, and 48V [4].
Samsung Galaxy S26 Series Charging Specifications
| Model | Battery Capacity | Max Charging Power | Required Protocol | Charging Speed (30 min) |
|---|---|---|---|---|
| Galaxy S26 | 4,500 mAh | 25W | USB-PD 3.0 + PPS | ~50% |
| Galaxy S26+ | 5,000 mAh | 45W | USB-PD 3.0 + PPS | ~65% |
| Galaxy S26 Ultra | 5,000 mAh | 60W | USB-PD 3.0/3.1 + PPS | ~75% |
The critical distinction for suppliers is that wattage alone does not guarantee compatibility. A 65W charger without PPS support will only deliver standard USB-PD charging speeds (typically 15W-25W) to Samsung devices, even if the power rating exceeds the phone's maximum requirement. This is why Samsung's own 65W Trio charger was reported by users to not trigger Super Fast Charging 3.0 on the S26 Ultra—it lacks the specific PPS implementation required [3].
To get fastest charging you need USB-C charger with USB Power Delivery with PPS. Samsung newer 60W adapter gives full speed. Third-party like Anker or Ugreen work if they have PD+PPS [3].
For B2B suppliers selling on Alibaba.com, this means product listings must clearly specify both power rating and protocol support. Simply advertising '60W Fast Charger' is insufficient—buyers need to know whether PPS is supported and at what voltage/current combinations (e.g., 20V 3A for 60W output).
