A 100W USB-C power adapter with multiple voltage outputs that fast-charges compatible laptops and phones from a single compact unit
This 100W USB-C power adapter replaces the original charger for MacBook Pro models from 2017 to 2022 and MacBook Air models from 2018 to 2022. It also supports iPad Pro 11 inch and 12.9 inch models from 2018 and 2020, plus iPad Air 10.9 inch from 2020. Any laptop, tablet or smartphone with a USB-C charging port can use this adapter.
The adapter accepts 100-240V input at 50-60Hz and 1.8A. It provides fixed output profiles of 5V at 3A, 9V at 3A, 10V at 5A, 12V at 5A, 15V at 5A and 20V at 5A, topping out at 100W. It will automatically step down to 29W, 30W, 45W, 61W, 67W, 87W or 96W when the connected device requests less power. Devices requiring more than 100W cannot be charged at full speed.
The charger housing is light and compact for travel or desk use. A USB-C to USB-C cable is supplied, so no separate cable purchase is needed. Built-in IC chip protection guards against short circuit, over-voltage, over-current and over-temperature conditions. The unit meets electrical safety and design standards for household and office environments.

This 100W charger supports the full 20V-5A output needed for 16-inch MacBook Pro models, while lower-wattage adapters such as 87W or 96W may charge more slowly under load.
The charger automatically negotiates power delivery down to 30W or 45W for MacBook Air models, so it charges at the laptop's maximum supported speed without overloading it.
The USB-C port delivers the full 100W via Power Delivery 3.0, matching the 20V-5A specification used by 16-inch MacBook Pro models for maximum charging rate.
