Cold hands, as we all know are not much fun. So having a little gizmo that you can pick up and grab a quick blast of heat from is going to prove popular.
Known simply as the Hot-Rox, this is a battery powered device that looks like a rock. This one is a bit smarter though as built inside is a host of components that will deliver some much needed heat even on the coldest of winter days.
To use you simply need to flick the switch to either medium or high heat setting and within 15 seconds it will be up to full temp and ready to warm!
The Hot Rox hand warmer is powered by a rechargeable built-in Lithium battery which will provide around 6 hours of heat per charge. It makes a great gift idea for those who feel the cold or simply buy one for yourself and be able to warm up whenever needed!
