Here is another charger alternative you can use for your gadgets that make use of a different type of energy. HYmini is a stylish, portable wind turbine that is amazingly versatile, saving up green electricity and dishing it out to 5V devices as required. It comes with a variety of connectors and can be mounted to your bike or your arm.

HYmini comes in your choice of green, black or white and includes a “1200 mAh built-in Lithium Ion Polymer rechargeable battery power bank”. The battery stores both wind-generated power and also solar power generated by miniSOLAR, a small self-contained solar panel included in the main HYmini package but also sold separately.

One notable drawback of the HYmini mentioned by GadgetReview’s testers is that it’s not compatible with either the iPod Shuffle or even worse, the iPhone. Non-Shuffle iPods are OK though, as they connect via the HYmini’s included USB connector. On the other hand, one commenter disputes this, stating the “iPhone is designed to switch from 12V to 5V power source for recharging when it is plugged to the computer/laptop.”
