USB-IF, the organization responsible for developing standards for USB ports and cables, has released a new version of the USB-C standard. Devices using the updated version of USB-C can accept up to 240W of power. According to CNET's calculations, this power will allow powering large-screen, 4K-resolution monitors and gaming laptops.
Previously, the maximum power for USB-C compatible power supplies was 100W. The USB-IF specifications state that cables supporting power transmission up to 240W must be marked with a special symbol.
Reversible USB-C connectors are used in modern computers, laptops, Android phones, and some Apple tablets. The latest devices – notably Apple computers based on the M1 processor – support the new Thunderbolt / USB 4 format. It is compatible with older USB devices, but still allows you to connect devices that require high data transfer rates, such as 6K monitors.
