The industry group that develops the technology, known as the USB Implementers Forum (USB-IF), calls the 240W option “Extended Power Range,” or EPR. It adds that cables that support the additional power capacity will have additional requirements and carry specific icons so that people can easily identify them. The new cables will also need to support up to 5A and 50V to be compliant.
There’s already a myriad reasons why USB-C is favored by electronics manufacturers. The connector is versatile: It works with a host of devices, from smartphones to laptops to external hard drives (and even the Nintendo Switch). It’s also easy to use: You don’t have to worry about which end is up when plugging it in, unlike a regular USB or micro-USB. The only caveat is that the number scheme for the cables, which points to the speed at which they transfer data, can be confusing for the lay user.
