Apple has boasted of the effectiveness of itslaptops are in their early stages on Monday, but it takes Apple’s most power-hungry laptop charger, a large 140-watt brick, to charge most of the new laptops.
Apple’s previous 16-inch MacBook Pros, which use the, came with a 96 watt charger. The 140-watt charger, which comes with the 16-inch MacBook Pro only, can power the laptop’s USB-C ports or its depending on the cable you connect to the charger’s USB-C port.
“MagSafe 3 has a new design that supports more power into the system,” Shruti Haldea, Mac Product Line Manager, said at the launch event. High-power charging also works with the laptop’s USB-C ports, thanks to a new standard this year that boosts USB charging power up to 240 watts.
Support for the new USB-C standard is important for anyone who wants to use the Apple charger on other devices or third-party chargers on Apple’s new MacBook Pros.
The 16-inch MacBook Pro has the same 100-watt-hour battery size as its predecessor, but it includes fast-charging technology so customers can pump in more power with a quick trip to the charger. The 14-inch MacBook Pro, available in configurations with smaller 67-watt and 96-watt chargers, has a 70-watt-hour battery that’s about 20 percent larger than the Intel model it replaces.
The high-power charger didn’t surprise Benson Leung, a Google engineer who worked on USB-C technology, including. “Apple was instrumental in proposing … new stress levels to USB workgroups, so it would make sense for them to consider releasing the first implementation,” he said Monday in a Reddit post.
Rapid support for the new high-power USB parallels the early adoption of USB-C in 2016 by Apple and Google, he added. Both companies were able to pick up on the new technology quickly as they helped set the standards, Leung added.
Apple’s new 14-inch and 16-inch MacBook Pro laptops are powered by their own. To his , Apple also announced its and more colorful smart speakers.
USB has amplified its influence in the tech industry by shifting from data transfer tasks to charging, first with phones and other small devices, and more recently with laptops. This has been a boon to consumers, who can use the same charging equipment to recharge batteries in laptops, headphones, tablets, phones, game consoles, and other products.
One area beyond the reach of USB is high-end gaming laptops, which need more than the maximum 100 watts that USB could deliver. To address this issue, the USB Implementers Forum standards group has extended USB charging with several new load levels up to 240 watts this year.
The USB-IF Power Delivery standard governs power levels so that a high-power charger does not damage a low-power device.
