MacBook Charger Care: Making Your USB-C and MagSafe Cable Last

Your charger goes everywhere your MacBook does, and it takes a lot of abuse: wrapped tightly, yanked out of the wall, stepped on and stuffed into bags. Good MacBook charger care doesn't take much effort, and it can save you from frayed cables, unreliable charging and even damaged ports on the Mac itself. Here's how to make your USB-C or MagSafe charger last.

Handle the cable gently

1. Unplug by the connector, not the cable. Pulling on the cord strains the joint where it meets the plug, which is where most cables fray.
2. Avoid sharp bends at the ends. Don't let the cable hang at a tight angle from the port or bend sharply around a desk edge.
3. Coil loosely. Wrap the cable in wide loops instead of winding it tightly around the power adapter.
4. Keep it off the floor where it can be stepped on, rolled over by chairs or chewed by pets.

Protect the charging ports

The ports on your MacBook are part of the logic board area, so damage here can be more expensive than replacing a cable.

• Don't use the Mac with the cable under tension, for example on your lap with the cable stretched to the wall.
• With MagSafe, let the magnetic breakaway do its job, but don't rely on it as a habit; a tripped cord can still pull the Mac off a table.
• Keep USB-C ports clean. Lint and dust can build up and stop a connector from seating fully. Shut down the Mac and gently remove lint with a soft, dry, non-metallic tool. Never use metal objects.
• Insert connectors straight and don't force them in at an angle.

Use the right charger

• Use Apple chargers or reputable certified ones. Cheap, unbranded chargers may not regulate power properly.
• Match the wattage. A lower-wattage USB-C charger may charge slowly, or not keep up while you're working. Check what your MacBook originally came with.
• Use a cable that's rated for laptop charging. Some USB-C cables are designed for phones and can't carry enough power.

Warning signs to stop using a charger

• Exposed wires, fraying or a split in the outer jacket
• A cable that only works at certain angles
• Burn marks, a melted smell or unusual heat at the plug or adapter
• Crackling sounds or sparks when connecting
• A bent or damaged connector, or a dented power adapter

If you see any of these, stop using it and unplug it from the wall. Don't tape over damaged cables; replace them.

Is it the charger or the MacBook?

1. Try a different outlet and a different known-good charger and cable.
2. On USB-C MacBooks, try each port.
3. Check for debris in the port with a flashlight.
4. If another charger works, replace yours. If nothing charges the Mac, the port, charging circuit or battery may be at fault.
