The Logitech K750 keyboard is powered by light

Logitech has solved the biggest drawback of wireless keyboards.

The Logitech K750 Solar Wireless Keyboard eliminates the inconvenience of battery replacement. The K750 can be charged with natural and artificial light. With a built-in battery, the device stays up and running for three months even in complete darkness, and the manufacturer comes with the Solar App, which shows how charged the battery is - or how much energy can be gained from a desk lamp. The keyboard, which is only 0,8 cm thick, has been given a Unifying transmitter. You can also easily connect other compatible wireless mice or keyboards to the receiver. In the name of environmental awareness, the K750 keyboard has been given PVC-free and recyclable packaging.

The Logitech Wireless Solar Keyboard K750 will go on sale in January 2011, with a suggested retail price of £ 69,99, which is approximately $ 21.
