How to Choose the Best Charger Wattage for Your MacBook Pro

While Apple provides a USB-C power adapter for all its MacBooks, having a spare charger is a great idea. You don’t have to sit and wait for your device to charge to start using it. There are many premium chargers from trusted brands that are more affordable than Apple’s pricey chargers, and RAVPower has some of the best.

But before you buy a charger for your MacBook Pro, it’s important to understand wattage requirements. MacBooks have different power requirements, and getting the right charger will ensure you maximize battery life.

Charger Wattage Requirements for Different MacBooks

DeviceCharger Wattage Requirements
MacBook Pro (16-inch, 2019)96 W
MacBook Pro (16-inch, 2021)140 W
MacBook Pro (15-inch)87 W
MacBook Pro (14-inch)67 W or 96 W
MacBook Pro (13-inch, 2016 and later)61 W or 67 W
MacBook Pro (13-inch, 2020 and later)96 W
MacBook Air (2022 and later)30 W, 35 W, 67 W, or 70 W

Larger MacBooks often need more powerful chargers to fill up their batteries at top speeds.

Understanding Charger Wattage

Electrical power is measured in watts (W), which is the rate of energy transfer. A charger with more watts has faster charging and multi-device charging capabilities. But it’s worth noting that a high-wattage charger won’t necessarily make your Mac charge faster. For example, if your MacBook is designed to use a 45W charger, it won’t draw more than 45W if you use a 100W charger.

If a charger’s wattage isn’t indicated, use this calculation: Watts = Volts x Amps. When you know the wattage, you can make an informed decision and buy the right charger for your MacBook.

What is Fast Charging?

Fast charging requires three things:

  • A device capable of fast charging
  • Knowledge of the maximum charging speed of your device(s)
  • The correct power source

To make devices charge faster, most manufacturers either vary a charger’s voltage or boost the amperage to increase the potential energy. Standard USB 3.0 ports output 5V/1A for small devices, and most phones are capable of handling 5V/2.4A. For fast charging, manufacturers increase voltage to 9V or 12V and above, and amperage to 3A and above. USB-C supports up to 100W and 20V, making faster charging speeds possible.

Most new MacBook Pro models, introduced in 2021 or later, support fast charging, going from 0% to 50% in around 45 minutes. Confirm if your Mac supports fast charging and the maximum wattage it can handle. Then get a charger that supports the wattage. The maximum charge speed is usually displayed in watts.

How to Choose the Best Charger for Your MacBook

Compatibility: Ensure the charger you buy is compatible with your MacBook model. Refer to your MacBook’s manual to know its charging requirements. The wattage rating must correspond with your MacBook’s requirements.

Portability: A portable power bank is ideal for travel. It’s lightweight and easy to carry around. You can throw one in your bag as you head out for vacation or business trips.

USB-C or MagSafe: Some older MacBooks use a MagSafe charger, while some newer models use a USB-C charger. Get the right battery pack for your Mac.

Cable length: A longer cable may be better if you typically use your MacBook while it’s charging. But the longer the cable, the more resistance. So don’t get a very long cable as your phone might charge slowly.

Brand reputation: Buy a charger from a reputable brand such as RAVPower. With over 45 million global users, you can be sure you’re buying a high-quality product that’s capable of powering your device efficiently.
