PPS chargers are an advanced subset of USB Power Delivery (PD) chargers that allow dynamic, real-time voltage and current adjustments for efficient, faster charging with less heat, whereas standard PD chargers deliver power in fixed voltage steps. PPS optimizes charging especially for devices like Samsung Galaxy and Google Pixel, while PD covers a broader range of USB-C devices including iPhones and laptops.
What is USB Power Delivery (PD) and how does it work?
USB Power Delivery (PD) is a universal fast-charging protocol that negotiates power between a charger and a device over USB-C, delivering up to 240W depending on the PD version. It works by delivering power at fixed voltage steps (5V, 9V, 15V, 20V), allowing devices like laptops, tablets, and smartphones to charge faster than older standards.
Standard PD eliminates compatibility issues, enabling safe power negotiation to provide optimal current and voltage to various devices. PD 3.1 extended maximum power to 240W, opening doors for even larger electronics. Brands like Wecent include PD chargers in their product lineup to serve a wide user base effectively.
How does Programmable Power Supply (PPS) differ from standard PD charging?
PPS is a sophisticated extension of PD 3.0 and 3.1 that enables chargers to adjust voltage in fine 20mV steps and current in 50mA increments dynamically during charging. This real-time adjustment matches exact device requirements, reducing heat generation, increasing charging efficiency, and improving battery lifespan.
Unlike fixed voltage in PD charging, PPS varies voltage and current within a specific range (for example, 3.3V to 21V), granting more precise power delivery—especially beneficial for smartphones like Samsung Galaxy and Google Pixel for their “Super Fast Charging” modes.
Which devices benefit the most from PPS charging?
Flagship Android phones, especially recent models from Samsung Galaxy and Google Pixel series, benefit significantly from PPS charging as they support the protocol to reach maximum charging speeds safely. PPS reduces heat and energy loss during charging, helping preserve battery health.
On the other hand, iPhones (from iPhone 8 onward) use standard PD fast charging via USB-C to Lightning cables but do not support PPS. Laptops and other medium-to-high power devices usually rely on PD rather than PPS, because PPS is mostly limited to a maximum of 100W, sufficient for smartphones but less common for larger devices.
Why is PPS considered more efficient than standard PD?
PPS charger’s ability to adjust voltage and current in real-time eliminates the energy lost as heat, which tends to occur in fixed-step PD charging. This means faster charging speeds, less battery temperature rise, and longer battery health.
The precision of PPS reduces power conversion inefficiencies. For example, Wecent’s PPS-supported GaN chargers provide superior thermal management, enhancing device longevity and charging speed while maintaining safety under rigorous testing standards like CE and FCC.
Can PPS chargers work with all USB-C devices?
Yes, a PPS charger is also backward compatible with standard PD, meaning it can charge any USB-C device that supports PD, but the dynamic voltage adjustment feature only works if the device itself supports PPS. Otherwise, charging happens at the regular PD fixed voltage steps.
This universal compatibility makes devices like Wecent’s multi-port chargers flexible solutions for consumers with mixed device ecosystems, ensuring optimal charging for both PPS-enabled phones and regular PD-compatible devices.
How do PPS and PD chargers affect device battery health?
PPS chargers improve battery health by reducing heat generation through precise power delivery matching the device’s needs. Lower heat results in less battery stress, which extends the lifespan of lithium-ion batteries in smartphones.
Standard PD chargers, while fast, use fixed voltage settings that can generate more heat, potentially accelerating battery degradation over years. Wecent emphasizes this advantage in their PPS-enabled chargers, which focus on combining performance with battery longevity.

How is charging speed influenced by choosing PPS vs PD chargers?
Charging speed depends on the device and charger compatibility. For PPS-compatible devices, PPS chargers provide faster, optimized charging by modulating voltage and current in real time, reaching peak charging speeds safely.
PD chargers deliver rapid charging but may be slower for devices optimized for PPS, as they only use fixed voltage increments. Wecent’s advanced chargers leverage GaN technology to support these protocols efficiently, enhancing speed without compromising safety.

Frequently Asked Questions
Q1: Can PPS chargers charge non-PPS devices?
Yes, PPS chargers are backward-compatible and will charge non-PPS devices using the standard PD fixed voltage steps.
Q2: Do iPhones support PPS?
No, iPhones fast charge using standard PD but do not support the PPS charging protocol.
Q3: Is a PPS charger worth it if I don’t have a Samsung or Pixel phone?
If you mostly use other USB-C devices, a standard PD charger suffices. PPS chargers excel with compatible devices but still work safely with others.
Q4: What is the maximum wattage for PPS chargers?
Under PD 3.0, PPS chargers usually support up to 100W, suitable primarily for smartphones and smaller devices.
Q5: How does GaN technology relate to PD and PPS chargers?
