Not unlike those wind-up flashlights or radios that have become quite popular as of late the FreeCharge Weza from Freeplay can also directly convert physical activity into usable power. In this case the Weza has a built-in foot pedal not unlike those used in air pumps which is used to spin a generator inside the unit.
In this case though instead of an inflated air mattress or bike tire you’re left with power at up to a 40-watt rate that’s used to charge an internal battery which can provide direct 12-volt power. With the proper cabling or converters the Weza can then be used to power emergency lighting, recharge electronics or even jump start a car. Now unfortunately it’s not specified how much pumping is required to fully charge the battery but given how much effort is needed to power a small LED flashlight you’re probably in for a great workout with this thing.
The FreeCharge Weza is available on the Freeplay website for $269.99.
