Monday’s MacBook Professional M1 Professional/Max launch launched two welcome charging options: The return of the much-missed MagSafe connector alongside USB-C and the introduction of super-fast charging.
Following the launch, it wasn’t actually clear whether or not this quick charging choice – which guarantees to convey a 50% recharge to the battery in simply half an hour – can be out there on each MagSafe and USB-C, through one of many Thunderbolt 4 ports.
Following the occasion, we contacted an Apple media consultant within the hope of attending to the underside of it, with no reply. Now, a brand new report appears to have gone some technique to answering the query, though not definitively.
Apparently, there won’t be help for quick charging through the USB-C ports, at the very least but. That’s as a result of the cables wanted to help the required USB PD 3.1 EPR normal aren’t out there but.
In keeping with a Reddit submit (through 9to5Mac) from a USB-C engineer, Benson Leung, reveals that whereas the charging brick itself might carry the mandatory help, there are but to be USB-C to USB-C cables in existence supporting USB PD 3.1 EPR.
“Apple was instrumental at proposing the 28V, 36V, and 48V new voltages ranges to USB’s working teams, so it could make sense that they have been planning on releasing the primary implementation,” he writes. “There are but to be a C-to-C cable rated at EPR ranges although. Apple’s utilizing some proprietary cable to MagSafe.”
As soon as these cables arrive, it’s doable that so will help for quick charging through USB-C. We simply don’t know but.
Jason Snell of the Six Colours weblog additionally identified a “quirk” concerning the 16-inch MacBook Professional USB-C ports required to the help the quickest charging speeds are absent.
He writes: “…on the 16-inch fashions – all of which include a 140W adapter – you possibly can solely do ultra-fast charging through MagSafe. Whereas there’s a brand new specification that permits for a lot greater energy supply ranges over USB ports, the Thunderbolt 4/USB 4 ports on the MacBook Professional don’t help it. You’ll be able to nonetheless cost through these ports, after all—simply not on the ultra-fastest velocity.”
Whereas this isn’t the largest deal on the earth, contemplating the MagSafe cable will certainly ship with the MacBook Professional, it could be good to have each options out there. We’ll proceed to hunt clarification from Apple on this matter.
