USB4 is built on Thunderbolt 3 architecture and delivers data transfer speeds up to 40Gbps, a meaningful leap over the previous USB 3.2 generation. But USB4's impact is not limited to data speed, it also brings a more integrated approach to power delivery.
The USB4 spec was designed to work fully alongside USB PD 3.1, meaning a single USB-C port can now handle up to 240W of power delivery, high-speed data transfer, and video output all at the same time.
The practical result for users is being able to connect a laptop to an external monitor and charge it simultaneously with just one cable. That cuts down on cable clutter in desktop setups, which is a real win for both aesthetics and practicality.
Widespread USB4 adoption requires compatibility on both the device and cable side; not every USB-C cable supports USB4 speeds, so anyone who needs fast data transfer should check the cable label for a USB4 or Thunderbolt marking.
As Charjett develops its high-power cable lineup, PD 3.1 compliance and quality internal construction are being adopted as standard for future USB4-compatible products too, keeping them useful well into the future.
