The USB bike generator is a device which enables one to charge their USB devices on the go, while riding a bike. The device is capable of providing power to two USB devices, through USB ports.
The device consists mainly of a stepper motor, which is used as a power generator for charging the USB devices and a voltage regulator for constantly maintaining the 5 volts of current required by the two USB ports. The device has a power conversion efficiency of 70 % from the generator to the two USB ports.
The device does have a limitation of providing not more than 5 Watts of power for charging the devices, which means one cannot charge high power devices through this device. The price of this device is currently not known, but it certainly looks like it will fit any cyclist’s budget.
