NewerTech’s Snuglet is a precision-manufactured ring designed to sit inside your MagSafe 2 connector port and provide a more snug fit to prevent your power cable from unintentional disconnections.
The original MagSafe design by Apple had a nice balance when it came to how much, or how little effort, it took to disconnect the power cable. A common complaint with the newer MagSafe 2 power connection is that unintended power cable disconnections occur too easily.
The NewerTech Snuglet solves this by providing a greater magnetic hold, making the MagSafe 2 power connection stronger. It installs quickly, stays installed, and is easy to remove for reuse on another laptop. The Snuglet costs US$19 for a box of two Snuglets and one removal tool. Go to www.newertech.com for more info.
