USB-C has become the standard connector for many smartphones, especially in the European Union, where new devices must use a universal charger. While all USB-C chargers look similar, their capabilities can differ significantly. One important feature to consider is PPS, or Programmable Power Supply, which is part of the USB Power Delivery (USB PD) standard. PPS allows smartphones to request specific voltage and current levels from the charger, adjusting them regularly during the charging process. This communication between the phone and charger helps improve efficiency and manage heat, which is crucial because excessive heat can degrade lithium-ion batteries over time. To check if a charger supports PPS, users should look for the term "PPS" printed on the power adapter or its packaging, often alongside information about USB PD. Both the smartphone and the charger must support PPS for this feature to work properly. The USB Implementers Forum (USB-IF), the organization that sets USB standards, notes that three components—device, charger, and sometimes the cable—are needed for full compatibility with PPS. Some advanced functions, such as battery management features on Samsung's Galaxy devices, require a USB PD charger with at least 25 W of power and PPS support. When replacing a charger, users should not rely solely on price, power output, or the presence of a USB-C port. The inclusion of PPS support can be a key factor in ensuring optimal fast charging and better temperature control. This is particularly important for users who want to extend the life of their smartphone's battery and maintain the device's performance over time. As more devices adopt USB-C and the USB PD standard, understanding features like PPS becomes increasingly relevant for making informed choices about charging accessories.
