HANDS ON Logitech is harnessing solar power in the K980 Signature Slim keyboard to solve a problem that might not have occurred to some users: battery anxiety.

The full-size keyboard (with a separate number pad) employs solar charging tech called Logi LightCharge, featuring a solar panel along the top of the device and a rechargeable battery within. Logitech reckons that when fully charged, the keyboard will last for four months if used in total darkness and take eight hours of light to recharge.

In practice, this means the keyboard should never run out of charge unless users are typing by feel in the dark for a few months or using the solar panel as an impromptu pen holder (it's a tempting groove at the top of the keyboard).
