You have a shiny new MacBook, an old MagSafe Power Adapter, and Apple’s MagSafe to MagSafe 2 Converter. What’s the best way to keep from losing it? Well, you could just leave it connected to the Power Adapter, but Bit Wise’s MagSafe Adapter Key Ring ($15) offers an alternative if you need to carry it around separately for some reason.
The accessory is made of stainless steel. One end is a loop, designed to fit on your keychain, and the other fits in the open end of the adapter. And that’s really it. The practicality may be somewhat questionable for most people, but at the very least it’s a neat-looking accessory.
