It has been so long since the development of the USB PD fast-charging standard, and they have changed in an exponential way, thus providing different changes, functions, and features that improve with each update and launch.
Likewise, they also have the same interface, being the USB Type-C interface.Īlso, the USB PD 3.1 has a maximum output power that can reach 240W, which is a huge improvement compared to its predecessors. In relation to the voltages with which it is compatible, the USB PD 3.0 does not present differences compared to the USB PD 2.0, since, like that version, you can get the voltages 5V3A, 9V3A, 12V3A, 15V3A, 20V5A, in addition to its maximum charging power that reaches the 100W. Finally, and being the third improvement, the number has been added to a certificate and digital signature function. In addition to that, the device software and hardware version identification, and software update functions through PD communication have been added. With the launch of the USB PD 3.0, it was possible to see a big difference when compared to the USB PD 2.0, and that is that you can see three big changes and improvements in its functions.įirst, a more detailed description of the device’s built-in battery characteristics has been added to this new standard. It is worth noting that, although it was launched in 2014, it did not become popular until a year later, in 2015, when Apple released a new MacBook, which featured the USB PD 2.0 fast charging standard.Ĭontinuing with the USB Power Delivery 3.0 fast-charging standard, it was presented to the public in November 2015. With the USB PD 2.0, you can get the voltages 5V3A, 9V3A, 12V3A, 15V3A, 20V5A, in addition to its maximum charging power that reaches the 100W. This has the USB Type-C interface, being one of the best known and more used around the world, and although it does not have another type of interface, which could be seen as negative, it has very good functions, among which are charging, data transmission, and audio transmission. Starting with the USB Power Delivery 2.0 fast charging standard, it was presented to the public in August, 2014. USB PD 2.0 vs 3.0 vs 3.1 In-depth Comparison USB PD 2.0
