Last week I blogged about the Top 5 Eco-Friendly Gadgets For Under $100 so you could be good to the planet and your wallet. But in case you want to be extra good to your wallet, here are the top 5 eco friendly gadgets for under $50.

1.The HYmini ($49.99) is a wind powered charger for your iPods and mp3 players, cell phones, PDAs and digital cameras. It’s light enough to take with you and you can even strap it to your bike or hold it while you job. If you want, add solar panels for even more renewable energy.

2. The Energy Saving Smart Strip Surge Protector ($40.99) by BITS Limited has ten outlets and autoswitches your devices on/off automatically, so you save money and electricity.

3. The Freeplay Indigo Self-Sufficient LED Lantern ($39.99) uses LED and is powered by reusable batteries or yourself, all you have to do is wind it.

4. The SideWinder Cell Phone Charger ($29.00), at 2.5 oz., is the smallest, lightest and most powerful portable cell phone charger made. And you’ve got “the power” because all you have to do to “charge” the charger is crank it, so it doesn’t waste any electricity or energy. What could be better?

5. The Rechargeable TykeLight Buddy ($29.00) is perfect for the kid in your life, or the kid in you. This night light is safe and easy: it doesn’t have any open electrical contacts and turns on automatically when lifted from the charger base.
