LG HFB-500 Solar Bluetooth Handsfree Car Kit
LG has a greener solution: the HFB-500 Solar Bluetooth Car Kit. Mount this light-weight box to your windshield and you're good to go and talk. Holding enough charge for 16 hours of talk time, the kit can get 1 hour of talk time for every 2 hours of exposure. Plastic clasps keep the box angled at the sun so you can careen around corners without loosing light.
When fully charged, the HFB-500 provides a massive 960 minutes of talk time. However, this can be improved - when it is in constant sunlight, the device will provide unlimited talk time.
LG Solar Power Bluetooth Car Kit HFB-500 Features: Bluetooth 2.0, call/end, volume key, last number redial, voice dialing, multi-connection (up to 2 phones), and easy pairing.
