If you have to replace a lost or damaged charger for your MacBook, MacBook Air or MacBook Pro, then it's important that you find the correct one for your particular machine.

We show you how to work out the charger that's best for your laptop.

Will the wrong charger damage my MacBook?

If you're buying an official MacBook charger from Apple then you can rest assured that choosing the wrong type won't cause any harm to your device.

While there are a variety available, ranging from 29/30W up to 87W, the more powerful ones won't overload your machine or effect your battery. They also won't make your MacBook charge any faster than normal, so don't think buying the top power rating will give you fast charging capabilities.

One thing to watch out for is buying a unit that's rated too low for your device. If you should do so then you'll find that it won't charge your device at all.

Chargers for the current MacBook range

At the moment the MacBook range is comprised of the MacBook, MacBook Pro, and MacBook Air. Each of these requires a different charger, which we've listed below.

Which MacBook charger do I need: Current range

As the current MacBook Air is an older design it doesn't support USB-C charging. For one of these you'll want a 45W MagSafe 2 Power Adapter.

There remains another remnant of Apple's past in the current catalogue, with the 15in MacBook Pro (2015). For this you'll require an 85W MagSafe 2 Power Adapter.

Check your cable

Before you replace the entire power charger it would be wise to check if the cable you're using is the correct rating for your device. Since the introduction of USB-C chargers, the cables have been separate from the main adapter, and as such they could be mixed up more easily.

Official Apple cables will have the words ‘Designed by Apple in California. Assembled in China' printed on them. Next to these will also be an alpha-numeric serial number that denotes to which charger they belong.

Which MacBook charger do I need: Cable

Ones beginning with C4M or FL4 are intended for the 29/30W USB-C adaptors used by the MacBook (2015 and later).

Those beginning with DLC or CTC can be used with either the 61W or 87W USB-C adaptors used by the MacBook Pros (2016 or later).

Apple recommends that if you should find your cable doesn't have a serial number printed on it then you should contact Apple Support as you may be entitled to a replacement.

Which Mac do I have?

If your machine is older than any of those listed above then you'll need to first ascertain its specific type before shopping for a charger.

Chargers for older Macs

As you can imagine, there have been quite a few combinations of chargers and machines throughout Apple's recent history.

These fall mainly into two main types - MagSafe and MagSafe 2 - the latter of which is split between MagSafe L and MagSafe T type connectors. MagSafe L is the longer, straighter connector that attached alongside the MacBook, while the T is the blocky square that was used on most MagSafe connectors.

Here's a breakdown of which style pertains to which device.
