Most of us have had the need to buy a second MagSafe charger for our Apple laptop at some point. Maybe our old charger has worn out over the years of use, or we simply want an additional one to keep at our home or workplace.
There are many different types of MagSafe chargers for sale on various websites. Many of the chargers that can be found for sale are not manufactured by Apple. These third-party chargers are typically much cheaper than the official Apple chargers, but can be dangerous to use. Third-party MagSafe chargers can shorten the life of your computer’s battery, or even damage the computer by causing the battery to expand. Expanding batteries can damage the main logic board, top case, or other expensive components of the laptop. There have even been reports of third-party MagSafe adapters igniting during normal use.
It is always recommended to use an official Apple MagSafe charger if one is available. You can ensure that you will receive an official charger by ordering directly from Apple or from an Apple Authorized Reseller like Small Dog Electronics.
