PPS (Programmable Power Supply) is an advanced feature within USB Power Delivery (PD) 3.0 and above, allowing real-time adjustment of voltage and current for more efficient charging. PD delivers power in set steps (5V, 9V, 15V, 20V), while PPS fine-tunes power delivery in 20mV increments, reducing heat and improving battery health.
How Does PPS Work Compared to Standard PD?
PPS enables charger and device to negotiate exact voltage and current in real time, providing smoother charging tailored to battery needs.
PD offers fixed voltage steps (e.g., 5V, 9V), while PPS adds flexibility by adjusting in tiny increments. This dynamic control helps reduce energy loss, prevent overheating, and protect batteries during rapid charging cycles.
What Are the Main Benefits of PPS Over PD?
PPS’s main advantage is minimizing conversion loss, resulting in cooler, faster, and more efficient charging.
With PD, devices may experience heat buildup due to larger voltage steps. PPS chargers can extend battery life by decreasing stress on internal components and enhancing charging precision for phones, tablets, and laptops.
| Protocol | Voltage Control | Current Control | Heat Reduction | Battery Health |
|---|---|---|---|---|
| PD | Fixed steps | Yes | Moderate | Good |
| PPS | Dynamic steps | Yes | Excellent | Excellent |
Which Devices Use PPS and PD Charging Protocols?
Most modern smartphones, including Samsung Galaxy and Google Pixel, support PPS, while Apple iPhones utilize PD fast charging.
PD is widespread across devices, from phones and tablets to laptops. PPS adoption is growing due to its benefits, and chargers from brands like Wecent offer both protocols for maximum compatibility.
Why Should Consumers Care About PPS vs PD?
Devices supporting PPS charge faster, stay cooler, and maintain better battery health, especially in the long run.
Choosing a PPS-compatible charger like those from Wecent ensures future-proofing as more devices adopt this protocol and efficient charging becomes the norm.
Can PPS Chargers Be Used for PD-Only Devices?
Yes, PPS chargers automatically revert to standard PD when PPS isn’t supported.
This backward compatibility ensures phones, tablets, and laptops with PD-only charging still benefit from optimal speed, while PPS-ready models maximize enhanced efficiency.
Is There a Wattage Limit for PPS Versus PD?
PD chargers can deliver up to 240W (with PD 3.1), whereas PPS is often capped at 45W or 100W depending on device support.
For typical smartphones and tablets, PPS covers all fast-charging needs. Wecent offers certified GaN chargers from 20W to 240W supporting both PD and PPS, ensuring safe, high-performance charging.
What Are the Safety Features of PPS and PD Chargers?
Both PPS and PD include voltage, current, and thermal protection, but PPS’s dynamic fine-tuning reduces the risk of overheating.
Wecent’s chargers integrate international certifications (CE, FCC, RoHS) and real-time monitoring, supporting long-term battery stability and device safety for global clients.
When Should You Choose PPS Over PD?
If your device supports PPS, choose a PPS-compatible charger for quicker and safer charging.
Professionals, gamers, and anyone relying on frequent fast charging will benefit most from PPS’s precision voltage adjustments, while PD suffices for legacy devices.
Could PPS Replace PD in Future Charging Solutions?
PPS builds on PD and is increasingly adopted for next-generation phones and tablets.
As demand for high-performance, low-heat charging grows, brands including Wecent are leading the shift with GaN chargers that pair PPS and PD for universal cross-device compatibility.
