The group overseeing the USB specification has dramatically expanded its energy capabilities to permit USB-C chargers to hold as much as 240 watts, permitting customary USB-C chargers higher latitude to take over from proprietary laptop computer charging bricks and energy gaming notebooks.
The USB Implementors Discussion board (USB-IF) issued revision 2.1 to the USB-C specification on Tuesday, as seen by CNET. The revised specification incorporates language that provides Expanded Energy Vary cables, which develop the aptitude of the USB-C cable to hold 100W to the brand new EPR vary of 240W. Gadgets supporting the brand new spec needs to be obtainable within the second half of 2021, CNET cited the USB-IF as saying.
What this implies is that laptop computer and telephone chargers that use the rising USB-C customary will carry extra energy. Most productiveness laptops can run on 65 watts, permitting them to make use of USB-C chargers that run on the older 100W specification. Gaming laptops, nevertheless, can demand considerably extra to energy their H-series CPUs and discrete GPUs, and use proprietary charging interfaces as well. It is going to be these notebooks that may profit from the brand new USB-C energy spec, permitting you to purchase a spare USB-C charging brick or use competitors to assist power costs down.

The USB-IF stated that the cable designs could also be barely completely different from regular cables, with a capacitor added to every plug to stop energy arcing between the plug and the USB-C connector. It’s much less clear, nevertheless, the way you’ll be capable of inform an EPR cable from a “regular” USB-C cable; whereas the USB-IF stated that every one EPR cables have to be electronically marked and visibly recognized with EPR-capable identification icons, the USB-IF didn’t publicly outline what these can be.
The USB-IF additionally didn’t say how the prevailing ecosystem of USB-C hubs will likely be affected. Presumably, producers should notify clients whether or not their hubs are EPR-capable, and design for the extra energy necessities.
USB-C already has gone a good distance in the direction of eradicating the mishmash of competing I/O plugs and connectors from the PC, with DisplayPort, Thunderbolt, and USB all working over the identical bodily connector. Now it’s going to standardize laptop computer energy bricks, too.
