Micro USB to Lightning adapter, MagSafe to MagSafe2 converter, Lightning adapter . . . all these Apple adapters have one important thing in common . . . they are all small and very easy to lose.
While you could always replace the Micro USB to Lightning adapter for $19.00 and the MagSafe to MagSafe2 converter for $9.99, the Lightning adapter that is included with the Apple Pencil is not sold separately. Likewise, the cap for the Apple Pencil that covers the lightning connector is also not sold separately.
A company called Cozy Industries (http://cozy-industries.com) has created a nice solution to help secure a variety of adapters to prevent loss. While these Cozy products are not entirely inexpensive (approx. $7 to $10 depending on the product), they are certainly worth consideration.
Cozy Industries makes a LightningCozy for the Micro USB to Lightning adapter, a MagCozy for the MagSafe to MagSafe2 converter, and a PencilCozy & PencilCozy Combo for the Apple Pencil, just to name a few. The PencilCozy Combo is comprised of two Cozy products – one that secures the cap of the Apple Pencil and the other that secures the Lightning adapter (the PencilCozy only includes the Cozy product to secure the cap of the Apple Pencil).
In brief, the Cozy product is a rubber strap that holds the adapter securely on one end and then serves as a strap to secure the Cozy product onto the cable or accessory that you would normally attach the adapter to. For instance, the LightningCozy would hold the Micro USB to Lightning adapter securely on one end and then the rubber strap would be secured onto a Micro USB cable. Likewise, the MagSafe to MagSafe2 converter would be secured onto the MagCozy on one end and then secured onto a MagSafe cable. In the case of the Apple Pencil, the PencilCozy product for the cap would hold the cap of the Apple Pencil securely on one end and then be secured to the Apple Pencil; the Cozy product for the Lightning adapter would be secured onto a compatible lightning cable.
Cozy products are a simple and easy way to keep your adapters and related accessories together, minimizing the odds of the adapters getting lost, while maintaining the convenient functionality of your accessories with or without the adapter (ex: For the LightningCozy, conveniently remove the Micro USB to Lightning adapter if you need a micro USB cable without worrying about losing the adapter. Quickly and easily reattach the adapter if you need a lightning cable.)
