Ever run down your mobile phone battery and your day is not quite over? Here’s a device for you: wellies!? Well, rubber boots.
The Orange Power Wellies have a “power generating sole” that converts heat generated from your feet into an electrical current that charges your mobile phone, which you can plug in at the top of your boot. Twelve hours of walking will give your phone an extra hour of battery life.
I can see it now. Business attire: skirt or nice slacks and wellies!
