MacBook Pro (Pre-2016) 15-inch 85W MagSafe 2 2012–2015
MacBook Pro (2016–2019) 13-inch 61W USB-C 2016–2019
MacBook Pro (2016–2019) 15-inch 87W USB-C 2016–2019
MacBook Pro (2021, 14-inch) 14-inch 67W (USB-C), 96W (MagSafe 3) MagSafe 3 & USB-C 2021
MacBook Pro (2021, 16-inch) 16-inch 140W (MagSafe 3) MagSafe 3 2021
MacBook Pro (2023, M2 Pro/Max) 14-inch & 16-inch 67W – 140W (Depending on model and charger) MagSafe 3 & USB-C 2023

Understanding Charger Compatibility and Usage

Choosing the correct wattage for a MacBook Pro charger is crucial to ensure optimal performance and battery health. While it is technically possible to use a charger with a lower wattage than recommended, it will result in slower charging and could potentially lead to the battery discharging during heavy use. Conversely, using a higher wattage charger is generally safe because Apple’s power delivery standards allow the MacBook to draw only the amount of power it needs.

Here are some important considerations regarding charger compatibility:

  • Lower wattage chargers: These may charge the MacBook Pro slowly and might not provide enough power during intensive tasks, causing the battery to drain even while plugged in.
  • Higher wattage chargers: Using a charger with higher wattage than the MacBook requires is safe; the device regulates power intake.
  • Connector type: Ensure the charger connector type matches the MacBook Pro’s port (MagSafe 2, MagSafe 3, USB-C). Using adapters may cause inefficiencies or potential damage.
  • Apple-certified chargers: Always use Apple-certified or genuine Apple chargers to ensure safety and compatibility.

Charging Technology and Power Delivery Standards

Modern MacBook Pro chargers utilize USB Power Delivery (USB-PD) technology, a fast-charging protocol that allows negotiation between the charger and the device to deliver optimal wattage. USB-PD chargers can dynamically adjust voltage and current to maximize charging speed while protecting the battery.

Key features of USB-PD relevant to MacBook Pro charging include:

  • Variable power output: Chargers can deliver different wattages (e.g., 20W, 61W, 96W, 140W) depending on the device’s requirements.
  • Rapid charging: Higher wattage chargers can charge compatible MacBook Pros significantly faster.
  • Safe charging: USB-PD prevents overcharging and overheating by regulating power flow.
  • Cross-device compatibility: USB-PD chargers can also charge other devices like iPhones, iPads, and USB-C accessories.

Apple’s introduction of MagSafe 3 with the 2021 MacBook Pro models combines the convenience of magnetic attachment with fast charging capabilities. MagSafe 3 chargers also support USB-PD, allowing for wattage negotiation similar to USB-C, but with a proprietary connector designed for ease of use and safety.

Understanding Charger Wattage and Charging Efficiency

The wattage rating of a MacBook Pro charger represents the maximum power output the adapter can deliver. Using a charger with the correct wattage is critical for maintaining battery health and ensuring efficient charging.

Key points to consider include:

  • Matching Wattage: Using the charger wattage specified for your MacBook Pro model guarantees optimal charging speeds and avoids stressing the battery.
  • Higher Wattage Compatibility: Chargers with wattages higher than required can safely charge your MacBook Pro, but the device will only draw the power it needs. For example, a 96W charger can charge a 13-inch MacBook Pro that requires 61W without issue.
  • Lower Wattage Limitations: Using a charger with lower wattage than specified may result in slower charging or the device drawing power more slowly, which can cause the battery to deplete during heavy usage.
  • Connector Types and Power Delivery: Recent MacBook Pros use USB-C or MagSafe 3 connectors, supporting USB Power Delivery (USB-PD) standards, enabling dynamic wattage negotiation between charger and device.

Identifying Your MacBook Pro Charger’s Wattage

To determine the wattage of your existing MacBook Pro charger, you can check the following:

  • Charger Label: The wattage is printed on the power adapter’s body, usually near the prongs or cable exit point.
  • Apple Support Documentation: Official Apple support pages list charger wattage based on model number or year.
  • System Information: On macOS, navigate to About This Mac > System Report > Power to see details about the connected charger.

Example label excerpt:
