MagSafe, however not USB-C? MacBook Professional quick charging plot thickens



Monday’s MacBook Pro M1 Pro/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 possibility – which guarantees to carry a 50% recharge to the battery in simply half an hour – could be accessible on each MagSafe and USB-C, by way of 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 method to answering the query, though not definitively.

Apparently, there is not going to be assist for quick charging by way of the USB-C ports, at the very least but. That’s as a result of the cables wanted to assist the required USB PD 3.1 EPR commonplace aren’t accessible but.

In response to a Reddit submit (by way of 9to5Mac) from a USB-C engineer, Benson Leung, reveals that whereas the charging brick itself could carry the mandatory assist, 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 might 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 assist for quick charging by way of USB-C. We simply don’t know but.

Jason Snell of the Six Colors weblog additionally identified a “quirk” concerning the 16-inch MacBook Professional USB-C ports required to the assist the quickest charging speeds are absent.

He writes: “…on the 16-inch fashions – all of which include a 140W adapter – you may solely do ultra-fast charging by way of MagSafe. Whereas there’s a brand new specification that enables for a lot greater energy supply ranges over USB ports, the Thunderbolt 4/USB 4 ports on the MacBook Professional don’t assist it. You possibly can nonetheless cost by way of these ports, in fact—simply not on the ultra-fastest velocity.”

Whereas this isn’t the most important deal on the earth, contemplating the MagSafe cable will certainly ship with the MacBook Professional, it might be good to have each options accessible. We’ll proceed to hunt clarification from Apple on this matter.
