The Ultimate Guide: What Wattage Charger for MacBook Pro

The Ultimate Guide: What Wattage Charger for MacBook Pro

Finding what wattage charger for MacBook Pro 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.

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 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.

Wattage Requirements for Different MacBook Pro Models

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 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) and 96 Watts (W) respectively.
  • MacBook Pro (15-inch): This slightly larger model has an increased wattage demand, requiring 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 (2018/2020): This model is designed for lightweight portability and easy everyday use, requiring only 30 Watts (W).

Recommended Charger Wattages for MacBook Pro

MacBook Pro models differ in terms of the standard and higher-performance charging wattages, depending on their hardware configuration. Below are the general recommendations.

Standard Charging Wattages

Here is the standard wattage for different MacBook Pro models based on their screen size:

  • 13-inch MacBook Pro: Apple's original charger is a 61W USB-C power adapter. Therefore, if you plan on getting a replacement charger, it is recommended to get one with the same wattage (or one that is higher, but not lower).
  • 15-inch MacBook Pro: For this model, Apple includes an 87W USB-C power adapter as the original charger. Opt for a charger with the same or higher wattage if you are looking for a replacement.
  • 16-inch MacBook Pro and newer 14-inch and 16-inch MacBook Pro models with M1 Pro/Max processors: For these, a 96W or a 140W (for M1 Pro/Max) USB-C power adapter is used respectively. It is suggested to maintain this wattage while buying a replacement.

It should be noted that using a lower MacBook Pro charger wattage may not damage the Mac, but will likely result in much slower charging times. Eventually, your MacBook might not charge at all while it's in use due to insufficient power.

High-Performance Charging

High-performance charging, also known as fast charging, requires a charger that can deliver power at a higher wattage. However, this fundamentally depends on the MacBook's support for fast charging.

  • 13-inch MacBook Pro:Supports fast charging using a 96W USB-C power adapter or higher for models released from 2020 onwards.
  • 16-inch MacBook Pro and newer 14-inch and 16-inch MacBook Pro models with M1 Pro/Max processors:Supports fast charging using the 96W (for 16-inch Intel models) and 140W (for M1 Pro/Max) USB-C power adapter.

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 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

  1. Compatibility

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.

  1. 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.

  1. Portability

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

  1. 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. 

  1. 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.

  1. 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.

  1. 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.

Here are some commonly asked queries about what wattage charger for MacBook Pro.

Is it OK to use 30W charger for MacBook Pro?

While it's possible to use a 30W charger for a MacBook Pro, it's not optimal. MacBook Pros typically require higher wattage for fast and efficient charging, normally around 60W - 96W, depending on the specific model. A 30W charger might charge your MacBook Pro very slowly and could be insufficient if your laptop is in heavy use.

Can you use a higher wattage charger for MacBook Pro?

Yes, you can safely use a higher wattage charger for a MacBook Pro. The laptop is designed to only draw as much power as it needs. Therefore, a higher wattage power adapter won't harm the battery. In fact, your MacBook will often charge faster with a higher wattage charger.

Is it better to charge MacBook at lower wattage?

Not necessarily. While charging at a lower wattage won't harm your MacBook, it might not be as effective or efficient. Your MacBook Pro is designed to handle certain power inputs optimally. Using a lower wattage charger might result in longer charging times and possibly inadequate power supply during demanding tasks.
