Logitech harnesses the power of the sun with its iPad Solar Keyboard Folio

Logitech's latest iPad keyboard offers two years of power on a single charge.

While there is no shortage of iPad keyboard cases, not too many attempts have been made at making solar powered ones.

Logitech, however, is taking a stab at it. Its new Solar Keyboard Folio uses the energy of the sun and lamps to power its Bluetooth keyboard. According to Logitech, the device's battery lasts two years on a single charge (assuming you use it for a maximum of 2 hours per day.) Useless number? Probably - but at least you'll never have to worry about the keyboard running out of juice.

Built for the second- and third-generation iPads, the device uses the same magnet mechanisms as Apple's Smart Cover for quick powering on and off.

This isn't Logitech's first foray into solar-powered keyboards. It's been here before with devices like Wireless K750 Mac keyboard, which was released last year.

Available now for pre-order, Logitech's Solar Keyboard Folio runs for $130. Expect it in stores later this month.
