If you purchased a MacBook Pro with Retina display or MacBook Air in mid-2012 or later, you probably already know that your MacBook charges via a MagSafe 2 connector. Because of this, your new laptop cannot be charged by older MagSafe chargers, including the one in the Apple Cinema Display and Thunderbolt Display. However, Apple does sell a $9.99 adapter that converts original MagSafe chargers to MagSafe 2 compatible chargers, allowing you to use your old chargers and displays.
The only issue I’ve come across when using the MagSafe 2 adapter is how small and easy to lose it is when not connected to a display or MagSafe adapter. When surfing the web for a way to fix the issue of constantly losing my MagSafe 2 adapter, I came across the MagSafe Key Ring, which is a device that can be used to affix your MagSafe 2 adapter to your key chain.
The device is pretty simple: it’s a small, magnetized piece of metal that attaches to your keychain. Since the MagSafe 2 adapter is magnetized, it will stick to the keychain attachment securely. Once the keychain adapter is on your keychain, you can easily attach and reattach your adapter when needed.
You can purchase the MagSafe 2 keychain adapter for $23 via Fancy. While this is expensive considering the MagSafe 2 adapter is only $10, it’s convenient and will probably save you money in the long run if you’re constantly losing your MagSafe 2 adapter when on-the-go.
