In the evolving landscape of mobile device charging technology, the term “PPS” has emerged as a significant innovation. PPS, which stands for Programmable Power Supply, represents a charging protocol gaining traction for its intelligent power delivery capabilities.
PPS Charger Meaning
A PPS charger is a type of power adapter that supports the Programmable Power Supply specification. This specification is part of the USB Power Delivery 3.0 standard. What sets PPS chargers apart is their ability to adjust the voltage and current during the charging process dynamically.
This is achieved through real-time communication between the charger and the charged device. The charger can alter the power output to optimize charging efficiency, reduce heat, and improve the overall lifespan of the device’s battery.
What is the difference between PPS charger and PD charger??
In the realm of USB charging, the distinction between Programmable Power Supply (PPS) and Power Delivery (PD) is pivotal. While the USB Power Delivery specification underpins both, their operational nuances set them apart.
Power Delivery (PD) Chargers
PD chargers are known for their ability to deliver higher power to devices, which is a significant step up from the conventional charging standards. They can supply power at multiple fixed voltage levels (5V, 9V, 15V, 20V) and scale the current accordingly, up to a maximum of 5A, depending on the cable’s capacity.
This allows devices to charge at the highest possible speed supported by both the charger and the device, up to 100W.
The PD protocol facilitates a two-way communication channel between the device and the charger. This channel is used to negotiate the power contract, ensuring that the device draws only the power it needs and that the charger can supply. However, the voltage levels are predetermined, and the charger switches between these set levels.
Programmable Power Supply (PPS) Chargers
PPS chargers are an evolution of the PD standard and introduce a more dynamic form of power management. They maintain the fundamental communication protocol of PD but with an added layer of flexibility. PPS chargers can fine-tune the output voltage in small increments (e.g., 20mV) over a range, typically from 3.3V to 21V, and adjust the current in real-time.
This granular control allows the charger to respond to the minute-by-minute demands of the battery’s charging cycle. For instance, as a battery approaches its total capacity, the charging process becomes more sensitive. PPS technology can reduce the voltage incrementally to avoid overcharging and minimize heat generation, which is crucial for maintaining battery health.
Is PPS Charging Worth It?
From an engineering standpoint, the benefits of PPS charging are multifaceted. The capability of PPS chargers to adjust power delivery in real time enables them to align with the optimal charging curve of a battery.
This not only speeds up the charging process but also minimizes the heat generated, which is a common issue with high-speed charging. Heat is a significant factor in battery degradation, so reducing it can prolong the battery’s health and lifespan.
Moreover, PPS charging can be particularly beneficial for devices with large batteries or those that require a more precise charging mechanism, such as laptops and high-end smartphones. For users who value speed and efficiency without compromising the longevity of their devices, investing in a PPS charger could be well worth it.
