Eco-friendly gadgets are all the rage and solar power is one of the easiest ways to conserve energy. The HFB-500 is actually a Bluetooth speakerphone with photovoltaic panels on the back, so when you place it on your car's dashboard or stick it to the car's windshield, it will soak up the sunlight. It's slim and compact, measuring only 3.6 inches long by 2 inches wide by 0.5 inch thick, and it's clad in a matte black finish and silver trim along the sides. On the front is a large multifunction button, and it's clad in a faux leather surface for better texture. On the right is a red Power button, and along the bottom third of the device is the speaker grille. The back of the device is home to the photovoltaic solar cells. The volume buttons are located on either side. The HFB-500 comes with a little transparent plastic holder, which you can slip the speakerphone into and then attach it to the windshield with suction cups.
