APRIL THANKO RODEO PART 1 OF 3: USB Wheel-Powered Gadget Charger for Bikes

Because They Just Can’t Stop Delivering the Hits

We’re entirely open about the our dorky lust for all things Thanko. The Akiba-based company pumps out a steady stream of products that often seem frivolous at first, but prove quite practical in real life - this month there were just too many, so we’re doing a rapid-fire posting of our favorite three (See also: Part 2 & Part 3).

Sitting around at Thanko headquarters just dreaming up ways to build spy watches and USB bento warmers and combination mobile chargers/hand warmers all day - and then actually creating and marketing the products - that’s living the dream right there. Way better than pounding keyboard! And among the dreams of Thanko:

Part 1: USB Wheel-Powered Gadget Charger for Bikes 

Japan’s been using those little mini-dynamo generators to power bike lights for decades, and that doesn’t require a whole lot of power. Charging a smartphone or GPS guide thingy is a different matter, but, when traveling (at least) 10 km/h or more, this implementation generates enough power to juice-up your device (the video below is instructive on this front).

It’s pretty simple, really: just attach the generator to your bike’s frame, making sure to align all appropriate parts, run the cable up to your handlebars or wherever, and there you go: semi-passive, human-powered electrical gadget juice!
