So I am working on a design for battery-heated wrist warmers. My mother has Reynauld's and arthritis, and as winter approaches it gets much worse.
My basic design is that I will take a form-fitting sleeve (made from a shirt or tube sock), weave nichrome wire through the sleeve, wrap thinsulate or space blanket around that, and then fix a nice-looking knitted wrist warmer over it. At the very least I think it would be a good start even without electric heating.
Ideally, the charger will charge the battery while also providing heat. My specific question is: can the charger I linked to provide that? In a more general sense, I would appreciate any suggestions you might have!
Thanks, and happy holidays!
