Recently, the United States Patent and Trademark Office awarded Apple patents relating to the “Wearable Electronic Device Storage Box”, which is described in the patent description as an accessory to AppleWatch, which functions like a small box of AirPods to charge the watch.
In the patented image, the accessory is rectangular in shape and needs to be removed before the strap can be recharged. The case contains a groove for the strap, and the recessed portion of the charge has a magnetically attractive design. This accessory is in the shape of a box that users can put together in a garment or bag while charging.
In addition to this portable charger, it is even more rumored that Apple will launch a battery strap for AppleWatch, watch the battery life can be an additional day.
