Key characteristics of the USB PD 3.1 specification include: (From here on out itРІР‚в„ўs useful to know the Volts x Amps = Watts formula РІР‚вЂњ more) We know work began on the project in 2019 or earlier, so this required some forethought.Р”В«rad Saunders, chairman of the USB Implementers Forum, told 9to5Mac:Р”Р„pple is one of the seven USB Promoter companies that co-sponsors the development of the USB base specifications, including of course the USB Power Delivery specification so it is not a surprise that they would develop a charger that aligns with the newest USB PD R3.1 spec.Р’В Powering higher performance laptop computers is clearly once of the primary use cases for the new higher power capabilities of the spec. WeРІР‚в„ўre not even a half a year after revision 3.1 of the USB Power Delivery (USB PD) specification was ratified, and Apple has launched a product using this standard. WeРІР‚в„ўre likely to see a similar sea change, except this time, it might not just be laptops. Incidentally, HP was the first to introduce a (micro) USB-powered laptop all the way back in 2013. This is reminiscent of when Apple first launched the USB-C MacBook in early 2015 (and Google almost immediately followed days later with their own USB-C charging Pixel Chromebook) and the laptop industry soon all went to USB-C. Apple, which is often tempted into messing with standards is apparently leading the (ahem) charge on USB-C PD R3.1. Other companies have hacked USB-C to get over the 100W limit of USB-C (actually going from 5A to 6.5A instead of a higher voltage). Meanwhile AppleРІР‚в„ўs Power Adapter Tech Specs leave more than a little to be desired: Regulators are calling it USB PD R3.1 spec. In fact, there isnРІР‚в„ўt even a cool name for it. The standard is so new that USB-C cables that are compliant arenРІР‚в„ўt even on the market yet, and itРІР‚в„ўs part of the reason you can only charge at that speed with AppleРІР‚в„ўs $49 USB-C to Magsafe adapter cable, not directly to the USB-C ports that charge below 100W. ItРІР‚в„ўs one of the first such adapters and certainly the first laptop to use the standard. But whatРІР‚в„ўs hugely more interesting is that itРІР‚в„ўs USB-C Power Delivery 3.1 compliant. But this could be the biggest step change in the electronics industry this year.Р”Р„pple chose the gallium nitride (GAN, via Verge) format to allow it to be in a smaller package, and thatРІР‚в„ўs certainly something we can get behind. Along with all of the fanfare during yesterdayРІР‚в„ўs MacBook Pro launch, one thing I wasnРІР‚в„ўt expecting was a 140W USB-C power adapter.
