=Project overview=

Background
Bicycle dynamos are nothing new, but charge-while-you-ride technology has improved by leaps and bounds in the last few years.These days you can charge just about any device that uses USB power using your own physical exertion, including smartphones, tablets and rechargeable lights.

problem statement
Design a charge device that can fast charge just about any device that uses USB power using your own physical exertion, including smartphones, tablets and rechargeable lights.

deliverable&specifications
supply a constant 5V 2A output to make sure charge smartphone fast.

make it portable,and it can be used widely

use a big power generator and can charge 2-3 smartphone at same time.

goals
As a group project, we have pinpointed our design constraints, we divided the project as 3 parts: generator, DC-DC converter(to constant the variable input), battery. We will focus on designing the DC-DC converter. And buying a suitable generator and battery charger part.
