The USB Implementer Forum has updated the file Specification for power supply in USB type C 2.1 to support up to 240W. Currently, the standard exceeds 100W, which means that it simply does not provide enough power for many more meaty devices. Raising the voltage from 20V to 48V should give manufacturers enough space to make it a truly universal charging standard.
We see this as a great advantage for gaming laptop manufacturers or, rather, for us, the players who have to juggle so many different power bricks; it's rarely fun to try to find the right power connector for your machine. The idea that you could get a generic brick of USB type C power supply is surprisingly surprising. Not really.
Lots of thin, lightweight laptops manage to use USB Type C connectors, although they tend to stay well below 100 W, with 65 W chargers being surprisingly common. Throw in a serious high-end CPU and a discreet graphics card, but you'll soon be able to go up to 200 W or more.
In fact, the 240W may even be a bit limiting for some of the most extreme laptops, but there will always be exceptions and exceptional machines that have ridiculous power requirements. Maybe a universal standard will calm things down a bit, though we wouldn’t be surprised to see some machines packing a couple of chargers.
Manufacturers will take some time to start implementing the new standard and meet the new specifications. Manufacturers must comply with the USB PD Extended Power Range (EPR) specification. Of course, any wiring will need to be complied with and will also need to handle up to 50 V.
