They don’t do it especially frequently, but Apple does sometimes change the power or sync connectors on their computers and mobile devices. You may find yourself the proud owner of a MagSafe to MagSafe 2 converter so that you can use your computer with some older Apple power adapters or the MagSafe power connector on some of the Cinema or Thunderbolt displays. Those converters are so tiny it’s easy to lose them, and $10 a pop begins to add up quickly. With the MagSafe Adapter Key Ring from Fancy, you’ll know that your converter is held magnetically to the little fob on your keyring. You’ll be able to see at a glance before you head out the door if your converter is with you. The MagSafe Adapter Key Ring is $23. It will pay for itself quickly if you tend to lose a lot of those converters.
