Walking Charger

13.08.2014 | |

The Walking Charger allows users to charge the batteries in their mobile electronics devices anytime, anywhere – just by walking.

You can charge your Smartphone battery by walking for just a single hour wearing the Walking Charger.

The Walking Charger is a small device that is embedded within OEM branded footwear products. Markets include consumer, commercial work boot, recreation and military applications.

With the Walking Charger, consumers have an off-the-grid capability to charge portable electronic device batteries as they walk. Alternatively, the Walking Charger can also be used to provide direct and immediate power to a wide range of electronics such as footwear heaters or GPS locators.

The Walking Charger has powerful environmental appeal. It gives users personal electric power without depending on the grid and without the waste management problems associated with battery disposal or recycling. Accordingly, the Walking Charger will be an important gateway product in the rapidly growing wearable electronics industry.

At product inception for recreation boots and work boots the power output of the Walking Charger is anticipated to be up to 2.4 watts and 1 watt continuous at a normal walking pace of 5 km/hr (3.1 mph). One hours’ walking will charge a Smartphone battery. This is a 20-50X advancement on related applications.
