16-Inch M3 MacBook Pro Can Fast Charge Over USB-C With 240W Cable

[MacRumors]

Apple's latest 16-inch M3 MacBook Pro models are able to fast charge at 140W over USB-C with a 240W USB-C cable, according to a support document that was updated today.

2021 and 2022 16-inch MacBook Pro models with M-series chips are limited to faster 140W charging with the USB-C to MagSafe 3 cable that Apple provides due to USB-C limitations, with the USB-C ports offering only up to 100W.

The 2023 16-inch MacBook Pro can charge at the full 140W through MagSafe or through a USB-C port when a 140W+ power adapter is paired with a 240W cable, such as the 240W USB-C cable that Apple began selling in September.

This update is only applicable to 16-inch models as 14-inch models can fast charge with a 96W charger, which USB-C ports were already able to provide for older machines.

The option to fast charge a 16-inch M3 MacBook Pro at 140W over USB-C gives MacBook Pro owners more options when it comes to charging, though it is worth noting that the 240W cables are limited to USB 2.0 data transfer speeds.

Why is this news. It would be news if it could charge at 240W.

Seems like news to me.

so why is the new 16" m3 able to fast change if the port is the same? what makes that usb c port able to do it

Hey have you always wondered how to make your battery crap out quicker? Wonder no more.

Because in the announcement apple said it could only fast charge with magsafe, now they’re clarifying

Thats not a power cable.. thats a heating coil... plug it in and put a wok on it.. cooks faster than iPhone 15 Pro.

Boils water scarily fast!

Unless you pair a BMW and iPhone 15 Pro.

At the time those were released, USBC only allowed 100 watt charging. The standards have been updated to allow higher power charging, so Apple added support for the new standards in the new hardware.

There must have to be some serious safety regulations (I must admit I'm not so up to date and would have to take a deep dive on that subject sometime) on these now... a bad cable carrying a lot of power can quickly become a fire hazard. Wonder what safety features they incorporate.

This is why I only ever rely on first party chargers and cables (for Apple, Microsoft and Raspberry Pi).. I have always relied on Apple USB chargers, even for non Apple devices. Their build and power stability are top tier.

USB-C 2.1 spec? https://tripplite.eaton.com/products/usb-connectivity-types-standards

Was the M1/M2 is on USB-C 2.0 spec?

 

[falkon-engine]

Nice little precursor to thunderbolt 5 (which supports up to 240W ).

 

[eropko]

I foresee more screenshots with 80% battery capacity after 80 cycles.

 

[bottsjw]

And so the value add of losing a perfectly good port to MagSafe is now .... what?! (if you say trip hazard 🤦‍♂️ )

Then why didn’t they say the new MacBook has a faster usb c port that’s a big change

e-bikes... yikes

Every time I hear about e-bikes... I think house fire. Imagine using an Apple cable to charge one, only for it to be the shoddy, knock off battery to go up in flames.

Do you want a battery guarantee of 1 week?

You know that they will enable this feature in about a year when M4 showing up in geekbenches.

USB-C is basically just a casing for the technology inside. Not all USB-C ports are created equal.

First of all... tripping hazard.

Second of all, this computer replaces the 13" M2 so not only did it not lose a USB-C port, but it gained MagSafe, HDMI, SD, and all the other nicer things which come with the new MPB design.
