MacBook Pro Charger Wattage: The Ultimate Guide

Finding Macbook Pro charger wattage can often be a confusing task, especially for those who are not familiar with how charger wattage affects the performance of their devices.

This comprehensive guide will clarify this puzzle by explaining the concept of charger wattage, the specific wattage requirements of various Macbook Pro models, and valuable recommendations for choosing the most suitable charger wattage. Furthermore, this article will discuss important factors to consider when selecting a charger for your laptop, ensuring a smooth and efficient charging process.

How to Understand the Wattage of a Charger?

Wattage is the crucial factor that determines the charging speed of your device, as it represents the total power running through the charger. In other words, having a higher wattage for your phone charger translates to a faster charging experience. When looking for a new charger, it's essential to consider the wattage to ensure it meets your charging needs.

How many watts is a Macbook Pro charger? If the charger's wattage isn't explicitly mentioned, you can utilize the following formula to calculate it: 

Watts = Volts x Amps

By knowing the voltage and current ratings (in amps) of the charger, you can easily determine the Macbook Pro charging wattage providing you with an estimated charging speed for your device. As a result, understanding the wattage of a charger enables you to make informed decisions when purchasing a suitable charger for your device.

What Watt Charger for Macbook Pro?

It's very important to know Macbook Pro charging wattage as the power needed can vary significantly depending upon the model and its features. Below is an overview guide to help you:

• Macbook Pro(13-inch): This model requires a power supply of 60 Watts (W) or 61 Watts (W). It's optimal for lightweight, everyday use.
• Macbook Pro(14-inch): More powerful than the 13-inch version, this model has a bit higher wattage. It has two variants, requiring 67 Watts (W), 70 Watts (W), and 96 Watts (W) respectively.
• Macbook Pro(15-inch): This slightly larger model has an increased wattage demand, requiring 85 Watts (W) or 87 Watts (W). This makes it more proficient at handling more complex, power-intensive tasks.
• Macbook Pro(16-inch, 2019): A bit larger and more efficient than the 15-inch model, the 2019 edition of the 16-inch Macbook Pro requires 96 Watts (W).
• Macbook Pro(16-inch, 2021): The most recent model of the 16-inch Macbook Pro requires the highest amount of power at 140 Watts (W). It's designed to perform heavy, power-intensive tasks in a smoother way.
• MacBook Air: The MacBook Air (2018 and later) models require 30W for optimal charging, designed for lightweight tasks and portability, while 2022+ models support up to 70W. Older models (2012-2017) use a 45W MagSafe adapter.

Here is a summarized chart for Macbook Pro models and their corresponding chargers/adapters, along with the watt details for each model:

For those using the latest chips, such as the M3, M2, or M1, it’s important to match the charger’s wattage with the requirements of your MacBook model to ensure optimal charging performance. For example, MacBooks with M3 chips may benefit from higher-wattage adapters like the 96W or 140W USB-C power adapters to make use of fast-charging capabilities, whereas earlier MacBook models with M1 or M2 chips may require slightly lower wattages like 61W or 67W.

Fast Charging Wattage Needed for MacBook Models

In addition to understanding the required wattage for standard charging, it's also important to consider which MacBook models support fast charging. Fast charging allows you to recharge your device quickly using higher-wattage adapters. Here’s how it breaks down for different models:

14-inch Macbook Pro (2021 or later): For faster charging speeds, the 14-inch model can use either a 96W USB-C power adapter or a 140W USB-C power adapter, depending on your needs.

16-inch Macbook Pro (2021 or later): The most recent 16-inch Macbook Pro charges the fastest with a 140W USB-C power adapter, making it the top choice for those who need to power up quickly.

Keep in mind that while fast charging can be convenient, it may cause the device to heat up a bit more than usual during the charging process. This is normal, but it's a good idea to disconnect the charger once the Macbook Pro is fully charged to let it cool down.

For maximum battery life span, Apple suggests charging your Macbook Pro to only about 80% whenever possible and avoiding small charge cycles (like charging from 95% to 100% repeatedly). 

Other Factors to Consider When Choosing a Charger for Your Macbook Pro

First and foremost, ensure the charger is compatible with your specific MacBook model. It is important to note that various models may necessitate varying charger types. Always refer to Apple's official documentation or consult professionals to understand your MacBook's charging requirements. Here are some extra factors that need to be considered except how many watts a Macbook Pro uses: :

Genuine vs. Non-genuine

While non-genuine (or replica) chargers come at lower prices, they could potentially harm your device. Genuine Apple chargers are recommendable as they are specifically designed and tested for your devices. Non-genuine alternatives may not comply with safety standards and can result in damage or even device failure.

Portability

If you're always on the go, consider purchasing an additional, lighter Macbook Pro charger for travel convenience. Some chargers also come with detachable plugs, making them more compact for packing or carrying around.

Flexibility

If you use multiple Apple devices, a universal charger might be a good option. Some chargers can simultaneously power a MacBook and another device, such as an iPhone or iPad. 

Voltage and Ampere Rating

Make sure your charger's voltage and ampere rating correspond with your MacBook requirement. A charger with too high voltage could potentially harm your device.

Cable Length

Consider the length of the charger cable. If you need to use your MacBook while it's charging and power outlets aren't nearby, a longer cable can be advantageous.

USB-C or MagSafe

The type of charger you need depends on your MacBook model. Older models use a MagSafe or MagSafe 2 charger, while newer MacBook models use a USB-C charger.
