This is quite nifty – a company called Ardica have created a combo gadget that simultaneously charges your gadgets and warms your cockles. They’re calling it a “portable power and heating system”. Basically, it’s a wearable power pack.

You’ll need a “compatible” jacket to take advantage of the heating. That’s the first time I’ve ever worried about whether my jacket is “compatible” with anything before. You’ll get 3 hours of high heat out of it, and 8.6 hours of low heat. They reckon the device will provide heat up to 100 degrees, which i’m hoping is Fahrenheit, rather than Celsius. Or Kelvin, for that matter…
