Kensington has unveiled the Bluetooth Hands-Free Visor Car Kit for mobile phones that comes with a spare battery so if you run out of power, you don't have to wait till you get home to continue using your handset while driving.

The devices comes bundled with a battery charger that plugs into a car's cigarette lighter and charges one battery pack while the other is in use. The charger also features a USB port for charging another device such as a mobile phone at the same time. Kensington says each battery pack offers ten hours of talk time.

The hands-free kit features a wire-clip that simply slides onto your car's sun visor and can be paired with up to three different phones at one time, so if you share a car you can don't have to change the hands-free kit every time you use the vehicle. The device also features three buttons that can be programmed with your most-dialled numbers and offers one-touch calling to these people, without having to fiddle around with your mobile phone. The device uses your Bluetooth ID to identify your handset and your three favourite numbers.
