Supporting the new USB-C standard is important for anyone who wants to use Apple's charger on other devices or third-party chargers on Apple's new MacBook Pros. The high-power charging works also with the laptop's USB-C ports, too, thanks to a new standard this year that boosts USB charging power as high as 240 watts. 'MagSafe 3 has a new design that supports more power into the system,' said Mac product line manager Shruti Haldea during the launch event.

The 140-watt charger, which ships only with the 16-inch MacBook Pro, can deliver power into either the laptop's USB-C ports or its resurrected MagSafe charging port depending on which cable you attach to the charger's USB-C port. Apple boasted about how efficient its new MacBook Pro laptops are during their debut Monday, but it takes Apple's most power-hungry laptop charger, a beefy 140-watt brick, to top up the biggest of the new laptops.Īpple's previous 16-inch MacBook Pros, which use the Intel processors Apple is kicking out of its Mac family, came with a 96-watt charger.
