MagCozy Leashes MagSafe 2 Converter to Power Adapter Cord

by

The MagCozy, like the KeyBit, is an innovative solution that is designed to help Mac owners keep track of their MagSafe to MagSafe 2 Converters.

Apple's MagSafe 2, which was introduced with the 2012 MacBook Air and Retina MacBook Pro, is incompatible with original MagSafe Power Adapter, necessitating the use of a small converter to charge MagSafe 2 devices with MagSafe adapters.

Currently featured on Kickstarter, the MagCozy leashes the converter to the cord of a power adapter, preventing the accessory from being lost or misplaced.

The MagCozy was inspired by a rubber band that attached the converter to the adapter, and the idea evolved into a simple but sleek sleeve that encompasses the converter and attaches to the adapter via a small loop. While the KeyBit was ideal for keeping a MagSafe to MagSafe 2 converter on hand while traveling, the MagCozy is ideal for home use.

Kickstarter backers can get a MagCozy in white, red, black, or blue for a pledge of $8. The designer, Ben Martinek, is also offering a limited edition MagCozy in an undetermined color and t-shirts for an additional fee.

In what scenario would you actually need to use the converter? I mean, your computer comes with a compatible MagSafe 2 charger, so that doesn't need the converter. So you'd only ever need it when you go somewhere, forget your own adapter, and are lucky enough to find someone who's got a Mac adapter, but it's a MagSafe 1 and not a 2. You then wouldn't attach your converter to their adapter! So when would you use this?

Anyone with a MagSafe 1 charger that has a MagSafe 2 MacBook.

Mine was for free

(with the purchase of a Thunderbolt Display) :D


Don't be absurd!

The Thunderbolt Display came free with the purchase of the $1000 adaptor.

this is an unnecessary little thing for people to buy.
Certainly there is a market for your idea and there are people who would benefit from it.
I would class this as backtracking.
When I said about being told off, I wasn't trying to say you are a kid, more that the post sounded like the voice of a child to me, that was a bit unclear.

NOT Apple Supported

WARNING: The Mag Safe Adapter, even by itself, is NOT supported by Apple.

If your MagSafe cord fails to disattach from being pulled, Apple will tell you that you are NOT using a valid cord with the Retina MacBook, and that you must use the T adapter. They will not support use of the MagSafe 2 Converter!

Use of a leash like this makes it even worse.

Take it from me. Mine failed to disconnect, and the cable came apart, leaving me with a limping puppy and a callous Apple who did not care at all! I was kind of shocked at the treatment I received from the Genius bar.

Do NOT use the MagSafe 2 Converter!
