The key to improving charging compatibility！Have you ever encountered such a situation: the power bank obviously supports fast charging, but the charging speed of some devices is very slow? This may be due to the lack of the PPS protocol.
What is the PPS protocol?
🔹 PPS (Programmable Power Supply) is an extended function in the USB PD 3.0 standard. It can dynamically adjust the voltage and current according to the device requirements to provide a more accurate and efficient charging experience.
🔹 Traditional fast charging protocols usually only provide fixed voltage levels (such as 5V, 9V, 12V), but the PPS protocol allows dynamic adjustment in units of 20mV, which is more suitable for modern devices.
Advantages of the PPS protocol
✅ Reduce heat and improve charging efficiency-dynamically adjust the voltage, reduce power loss, reduce device heat, and improve charging conversion rate.
✅ Compatible with more devices-PPS can match PPS fast charging mobile phones such as Samsung S series, Note series, Xiaomi, Huawei, and is also compatible with laptops (such as MacBook).
✅ Improve battery life – accurately match the voltage required by the battery to avoid overvoltage damage and extend battery life.
How to choose a PPS fast charging power bank?
🔹 Make sure the product is marked with support for USB PD 3.0 PPS, not just PD 2.0.
🔹 Choose a PPS power bank with a wider output range (such as 3.3V-11V or 3.3V-21V) to be compatible with more devices.
Conclusion
The PPS protocol is an important upgrade of modern fast charging technology, especially suitable for high-power fast charging. If you need to charge a smartphone, tablet or laptop, a power bank with PPS will be a better choice!
