The USB Type-C connector now makes it possible to build the most versatile cables on the market. The standard could also be applied to iPhones. A year ago, the USB Implementers Forum announced a new revision of the USB-C standard. With the USB-C 2.1 revision, the power potentially delivered by the interface, increases from 100W to 240W, allowing devices such as monitors and 4K TVs, printers and even gaming laptops to be powered via a USB-C interface.
To handle 240W of power, the USB Implementers Forum has modified the USB-PD specification. While the amperage will still be configurable up to 5A, the maximum voltage has been increased from 20V (USB-C 2.0 standard) to 48V. This new generation of USB-C cables is called Extended Power Range (EPR). USB-C EPR cables will have to meet certain requirements such as support for 5A and 50V, a minimum functional voltage of 53.65V and electrical components such as bypass capacitors rated for a minimum of 63V. Manufacturers are strongly encouraged to use damping capacitors at each end of the cable to prevent arcing damage when disconnecting. As you can see, these cables will obviously cost more…
Soon one connector, one power standard for everything?
However, there will be no physical changes to the plugs, so users can connect a USB-C 2.1 device to a USB-C 2.0 port and vice versa without any problem and especially without the risk of damaging hardware that may or may not be compatible with the EPR generation. USB-C 2.1 cables could start to come with gaming laptops and thus put an end to the various proprietary connectors that have been found on laptops for years. It would also open the door to standardization of power supplies. Club3D has just announced the arrival of cables with this new standard. It is now missing to the market that the manufacturers seize this one and generalize the connectivity a little everywhere.
