Review on 5200MAh Electric Rechargeable Double-Side Hand Warmer | Portable Pocket Hand Warmers & Phone Charger For Outdoor Sports | Heat Therapy Great For Women & Men In Winter By BRIGENIUS by Don Devine

This is a relatively inexpensive way to keep your fingers toasty. I would even consider purchasing a second one to keep one in each jacket pocket since it gets really cold here in the winter. It is not too heavy and fits in a coat pocket while leaving room for hands. Although I like the option to use as a charger i won't likely use that feature unless in an emergency. I like that its reusable and works similar to the little disposable packs without being wasteful.
