![]() ![]() That’s why it’s possible to charge your smartphone off your computer’s charger, but it takes forever to fuel up your computer with your smartphone’s charger. ![]() Plug a smartphone in, however, and it will use one of the lower-power options. Your MacBook requires a power adapter with the right wattage. ![]() So if you plug your MacBook into its charger, it’ll use the full 87 watts.

While this power adapter is compatible with any USB-Cenabled device, Apple recommends pairing it with your 16-inch MacBook Pro for optimal charging performance. Now, even though a USB-C charger may support it, you can’t just shoot 100 watts straight into your phone and expect it to work. I have a 2019 16' MBP with 8 cores of I9, Radeon Pro 5600 8 gb gpu, 64gb ram and currently on the latest Os 11.2. But USB Power Delivery (USB PD), a feature many USB-C devices support, complicates things by enabling “fast charging.” This means chargers with USB PD can generate between 0.5 and 100 watts by operating at 5, 9, 15, or 20 volts, and between 100 milliamperes and 5 amperes. For USB 1.0, it was 5 volts at 500 milliamperes for a maximum power of 2.5 watts. If I connect the 87W to the MacBook through a Satechi USB-C power meter it charges at 19.2V 1.4A 26.9W. So, in an effort to get everyone on the same page, the USB standard limits charging to certain ranges.
