LG has a greener solution, introducing a new concept in bluetooth technology: The Solar-Powered Bluetooth Car Kit HFB-500 by LG is the next generation of smart, clean technology. This plug and play model HFB-500 is easy to use and installs in seconds. Mount this light-weight box to your windshield and you're good to go and communicate through Bluetooth's wireless technology. 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. Up to 1100 hours stand by time. Features: Bluetooth Version 2.1, call/end button, volume key, last number redial, voice dialing, multi-connection (up to 2 phones), echo cancellation, noise reduction and easy pairing.
