Mobile devices are becoming more powerful by the day and their power consumption has increased definitely, making fast charging indispensable. In 2017, the USB Implementers Forum (USB-IF), the organization that supports the advancement of USB technology, added PPS fast charging to the USB PD 3.0 standard, creating a unified solution for today’s fast charging devices. That same year, Qualcomm’s QC 4.0 met the PPS standards, attaining a unified charging scheme.
So, what is Programmable Power Supply (PPS)?
PPS fast charging is the most advanced charging technology for USB-C devices. The technology adjusts the voltage and current in real-time, depending on a device’s charging status, feeding it with maximum power.
What’s the Difference Between PPS, PD, and QC?
Programmable Power Supply PPS allows for stepwise changes in current and voltage. It decreases the conversion loss during charging, ensuring the charge is more efficient. When the charge is more efficient, less heat is produced, and when less heat is produced, a battery’s lifespan increases. So, PPS fast charging is better for your device’s battery.
Power Delivery(PD) is a standard for handling higher power that was introduced by the USB Implementers Forum. It allows devices to charge fast over a USB connection. It provides high-speed charging with variable voltage using intelligent device negotiation. Devices negotiate a power contract to determine how much power they can pull from a PD charger.
Power Delivery is designed to allow devices to fast-charge over a USB connection. Its newest version, PD 3.0, is one of the most popular fast charging protocols. PPS is the latest addition to the PD 3.0 standard. PPS and PD protocols work seamlessly together. PPS allows for renegotiation of non-standard currents and voltages between the charger and the device.
Quick Charge (QC) is one of the most common fast charging protocols on the market and is found in many popular smartphones. It was invented by Qualcomm, which makes mobile CPUs. The charging standard supports backward compatibility, which means a QC 4+ charger can fast-charge a QC 3.0 device. Quick Charge achieves fast charging by increasing the charging voltage, boosting the wattage in the process. QC 5, the latest standard in Quick Charge technology, can recharge smartphones to 50% in five minutes.
Which Devices Support PPS?
Samsung Galaxy S20 was the first phone certified for PPS fast charging, but there are three other devices that likewise support the standard: Samsung note10, Samsung S20 ultra, and Samsung S21.
Can PPS Charge Laptops?
Yes, many laptops support the PPS charging protocol and can be charged faster, safely, and more efficiently.
