USB Power Delivery and its relation with USB Type-C
USB PD has been the de-facto fast charging standard for USB-powered gadgets since its release in 2012. Replacing the preceding USB Battery Charging specification, USB PD supports a significantly higher power level of up to 240W, and is now commonly used to fast-charge smartphones, laptops, and other gadgets.
To enable optimal charging, the newer USB Power Delivery Programmable Power Supply (USB PD PPS) standard supports configurable voltages. However, should two devices fail to communicate a suitable power rule, USB Power Delivery will default to the next power option supported by the relevant USB protocol, such as USB-C 1.5A.
Though the first revision of USB PD was compatible with standard USB Type-A ports in principle, few devices actually supported this functionality. Instead, manufacturers of USB PD devices went with the option of using USB Type-C or USB-C on both ends. For that reason, most smartphones these days come packaged with USB-C to USB-C cables. Type-A to USB-C cables can also be used, albeit at slower charging speeds.
USB Type-C mandate in the European Union (EU)
The EU mandate for mobile phones, tablets, and cameras sold within the region to be equipped with USB Type-C charging ports kicked into effect in 2023, and requires all manufactures to comply by the end of 2024. This mandate will extend to include laptops by spring 2026. This change presents a challenge for manufacturers, who have to swiftly navigate their way through new regulations while simultaneously working to prevent performance issues such as:
- Abnormal signal transmission when connected to displays
- Overheating due to poor cable quality
- Charging inconsistencies
