Apple’s premium 13-inch MacBook Pros are equipped to take advantage of the 87W power adapters, though users will see no benefit in terms of charge speed of change.
Although it doesn’t allow faster charging, an 87W AC adapter could provide a little more power to 13-inch MacBook Pro during heavy workloads.
The new 13-inch MacBook Pro models with four Thunderbolt 3 ports and 10th generation Intel processors have dual input power of 20.3 volts and 3 amps, and 20.2 volts and 4.3 amps. This technically means that they are able to accept power from the Apple 87W adapter supplied with the latest 15-inch MacBook Pro models.
Previous 13-inch MacBook Pro models from 2016 came with a 61-watt USB-C power adapter and support a rated consumption of 20.3 volts and 3 amps. That hasn’t changed on current low-end MacBook Pros, and Apple continues to include its 61W adapter with all 13-inch variants.
Sources told MacRumors that high-end 13-inch MacBook Pro models will not be able to load faster because the internal load settings are the same as previous generations.
However, some professional users may see an advantage with a higher power adapter during demanding workloads. An 87 W charger can also provide a little more free space if, for example, one processor is at its maximum while the MacBook Pro is connected to several external displays.
Users of the 13-inch MacBook Pro have long been able to safely charge using larger power adapters, although maximum charging speeds are capped at the machine level.
