Falling under the category of cool/green accessories, I have to give mention to the Scosche Solar-Powered solCHAT Bluetooth Speakerphone. The device features an integrated solar panel and rechargeable Li-ion battery. The device will pair up with your Bluetooth handset to give handsfree talking pleasure to you while drive. The design is clean and simple, and features 3 buttons… a volume up, volume down, and call/hang up. Easy. If you live in a cloudy climate there is also a USB charging cable included… So no worries, you aren’t forced to find sunlight to charge the unit.
You can pick one up from Scosche for $99.99.
