The HYmini is a handheld, universal charger/adapter device that stores energy collected from the wind and sun; a compact green portable power bank.
The HYmini recharges an integrated battery, which at the same time can be used to charge your iPod, mobile phone, PDA, digital camera or MP3 player. Strap it on your bike or your arm and let the wind recharge your devices as you speed down the hill on your bike.
The HYmini is a wonderful thing and collects wind energy like a charm. But, it also has solar panels that you can use. I works very well when you ride your bike. But, you don’t have to if you don’t want to. It’s great to set the HYmini outside to both collect wind and solar power too.
