The Apple MacBook Pro 15" (A1707, 2016-2018) uses the A1820 charger, which is the 61W or 87W USB-C power adapter depending on the MacBook Pro's model and configuration.

• 2016-2017 Models: These models usually come with an 87W USB-C power adapter.

• 2018 Model: This may also come with the 87W USB-C power adapter, but check your specific model for confirmation.

If you are looking for a replacement, make sure to get an 87W USB-C charger, as using a charger with too low power output may result in slower charging or no charging at all. The Apple A1820 charger is a safe bet, but there are also reputable third-party options available, as long as they are USB-C PD (Power Delivery) compliant.
