Charging Your MacBook Right with a MagSafe Charger

The MagSafe charger is specially designed to charge the Mac computer. The charger is built for maximum compatibility with a magnetic DC connector that ensures it stays in place. MagSafe power adapters come in different voltages to meet the power requirements of specific MacBook models.

How are the MagSafe and MagSafe 2 chargers different?

The MagSafe was the first generation of the magnetic connector charger. Its successor, the MagSafe 2, works under the same principle and only differs in appearance. It has a thinner cord than the MagSafe. Apple's new-generation laptops with the retina display were made thinner, so the MagSafe 2 power adapter was created for this range of computers. MacBook Air and MacBook Pro Retina are compatible with a MagSafe 2 charger (see manufacturer site for details). The two types of chargers are not interchangeable.

Is it possible to use the MagSafe adapter on a MagSafe 2 port?

Yes. Some generations of Mac computers are fitted with a MagSafe 2 port, which can be charged with a MagSafe charger using a converter. The MagSafe to MagSafe 2 converter is compatible with Apple displays that use the 'L' and 'T' connectors. You have to link the connector between the power port on the device and the adapter connection. The connector disconnects the same way as with a directly connected charger. See the manufacturer for details on proper MagSafe disconnection. The connector can work with Apple Thunderbolt Display, MacBook Pro with Retina display, 24 & 27-inch Apple LED Cinema Display, and MacBook Air with a MagSafe 2 port (see manufacturer site for details).

Does the voltage of your MagSafe power adapter matter?

Using a MagSafe charger with a higher voltage does not affect the system function, but the charging speed won't change. However, if the wattage of the adapter is less than the recommended input for your MacBook, it will impact the charging efficiency. Check with the manufacturer for the list for compatible Mac computers when buying a Mag charger. Note that the compatibility varies between T and L-shaped MagSafe adapters.

Which MacBook computers work with the 60W charger?

The 60W MagSafe power adapter (both T and L connections) work for the following devices:

  • 13-inch MacBook from the original to mid-2009 model.
  • 13-inch MacBook Pro mid-2009 to mid 2012.
  • 15-inch MacBook Pro mid-2009.
