Limited Fast Charge In 16-inch MacBook Pro, Supports Only MagSafe

With the launch of the new 14-inch and 16-inch MacBook Pro models at Apples October Event held yesterday at Apple Park, Apple for the first time brings a fast charge capability to the Mac. As it is on mobile too, this new mac capability allows users to charge the laptop battery up to 50% within 30 minutes.

This new feature is available on both 2021 model But there’s a slight difference in functionality which Apple didn’t really mention. While both models can be charged over Apple’s Thunderbolt or MagSafe, only the 14-inch MacBook Pro can be fast charged over the USB-C/Thunderbolt 4 ports as well as ‌MagSafe‌.

Furthermore, contrasting both models this means that the 16-inch MacBook Pro is limited to fast charging via the ‌MagSafe‌ port.

However we are not certain as to why Apple choose to limit the 16-inch MacBook pro but our guess is perhaps due to the fact that the Thunderbolt 4 ports on the 16-inche pro model are capable of charging at a maximum of 100W, and the 16-inch MacBook Pro uses a 140W power adapter hence it’s cannot spots both fast charging function.

Meanwhile, the 14-inch model uses a 67W power adapter for the 8-core machine and a 96W power adapter for the 10-core machine, so it doesn’t reach the maximum TB4 power delivery.

This limitation brought on the 16-inch MacBook Pro will not prove to be a big deal for most intend users, given that the ‌MagSafe‌ 3 port is made specifically for charging and won’t be occupied for any other reason.

In conclusion, this slight difference between the two seems worth pointing out given the various cable/ports setups intend owners could be visualizing for their workflow.
