The European Union passed a resolution to reduce electronic waste by implementing the use of USB-C ports on all electronic devices by the autumn of 2024. More electronic devices will inevitably adopt USB Type-C ports, which will drive the demand for high-wattage power banks and PD chargers, increasing the power load to 48V/5A.
Apart from charging, the USB Type-C port is also applied to the PC’s connection with small devices such as mobile phones and tablets. The interface even enables displays and SSDs to achieve higher transfer rates, as well as supports more transmission protocols. This triggers the question: will we witness easier device connections once all interfaces are unified into one?
Diversified Products Applications for USB Type-C
USB Type-C covers multiple protocols, including USB 3, Thunderbolt 3, Thunderbolt 4, etc. Also, different product applications correspond to different USB versions and speeds, as shown in the following table:
Although they all come in the form of USB Type-C, due to the differences in protocol versions and speeds, the matching of the system, device, and USB Type-C cable must be consistent to achieve the best performance, while different devices or systems require different cables. Taking just speed as an example, USB Type-C cables have the following variants:
As the transmission rate increase, the power demand for high-speed devices is also on the rise. Thus, USB Type-C products must be launched with different specifications to tackle the situation. In 2021, USB-IF released the USB PD 3.1 revised version, stating that the ERP (Extended Power Range) much reach 240W in maximum power to accommodate the high-power demand. All in all, the massive variety of cable specifications and version rates went out of hand, and the excessive variations have been driving consumers mad with confusion.
o end such a dilemma, in March 2022, USB-IF proposed cable validations combining the transmission rate and power capacity of cables, which also redefined the cable specifications. In the future, cables won’t be categorized by their versions, but by their common speed rate and power supply capacity.
The USB Type-C Compatibility Issues that Must Not Be Neglected
As the specification demands of various product types may differ, finding the most suitable USB Type-C cable has always been challenging, even for seasoned engineers. We’re way past those “one cable for all” days and can no longer achieve the top performance in all our systems and equipment tasks by simply grabbing the nearest cable. However, the majority of consumers had accommodated themselves to cable multitasking in their daily lives, while some even believe that all USB Type-C cables are supposed to be all-purpose. Consequently, even when the speed rate and power supply do not match, manufacturers still strive to achieve the lowest specification for all protocols in their products. Facing all possible usage scenarios, if the cable fails at the basic connection function, the consumers will certainly be very disappointed.
