Mobile maker LG was also there, showing off a solar-powered Bluetooth car kit (pictured) - the HFB-500 - which fixes to the car windscreen via suckers on its cradle and has a solar panel to recharge its battery. The device also doubles as an emergency charger for LG mobile phones and can be used as a portable speaker phone as well.
LG said it takes 33 hours to fully charge the HFB-500 using daylight - and a fully charged battery gives approximately 16 hours of talk time.
