MacBook: What is the maximum wattage of the power adapter?

If you don't have the original power adapter for your MacBook, you can use another one. We clarify the maximum wattage a power supply for the MacBook can have?

MacBook: Maximum wattage of the power supply

The original power supply of the Apple MacBook has 60 watts. You can also easily use the MacBook Pro's power adapter, which offers 85 watts.

• The power is measured in watts, i.e. a power supply unit with 60 watts can provide a maximum of this wattage of power.
• Your MacBook "only" consumes as much watts as it needs at the moment, up to 60 watts.
• You can easily use a power supply unit with a higher wattage.
• You can also use power supplies with a lower wattage, such as the MacBook Air with 45 watts, but it does not deliver enough power when the MacBook is under high load.
• You should be careful with the voltage volt (V). Use only a power supply that has the correct value. For the MacBook Pro, for example, that's 18.5 volts.
