Some of our devices are compatible with fast charging, and in all these cases, the standard they use is PD or Power Delivery. In addition to the PD (Power Delivery) standard, there are also other standards, such as the PPS (Programmable Power Supply) standard.
Below, we explain the difference between these two standards.
The main difference between these two standards lies in the management of voltage and current output. A charger compatible with the PD standard provides stable voltage and current during charging according to the technical construction of the charger. In other words, if the charger is capable of delivering an output power of 18.0W at 9.0V and 2.0A, this will be stable throughout the entire charging process.
The PPS standard, on the other hand, is capable of fine-tuning the voltage and current supplied by the charger, adjusting it according to what the device requests at each moment of charging.
It is necessary for both the device and the charger to be compatible with the PPS standard.
