There's genius in Logitech's Solar Keyboard Folio for the iPad: no one wants another gadget to charge. So, why not use the power of the sun to charge it instead? The gadget in this case is a keyboard case, designed to fit around an iPad 2 or third-generation iPad like a book cover. The iPad, but this is the first solar-powered one I've ever reviewed.
The keyboard has no AC charger, and no hole for an adapter. Bonded to the inside of the Keyboard Folio's cover-flap, the keyboard is comfortably wide, made of plastic, and has taller keys with more travel than accessories like the. I actually preferred the typing experience on shallower Keyboard Cover's keys, but it's still very good here.
The other genius idea in this case is its automatic pairing process: insert an iPad into the hard rubberized shell bonded to the thinly upholstered Folio, bend it into keyboard position by slotting two jutting feet onto the end into slots above the keys, and the keyboard turns on and starts pairing. It happens seemingly by magic.
Those who find the idea of no backup USB charging option might start panicking, but Logitech promises that a fully charged Folio will last for two years when typing two hours a day. Charging takes up to six hours in dim light but "much faster" in brighter light. In our office-use tests, the Folio seemed good to go after a few hours. There's no charge-status indicator, so it's a bit of a leap of faith.
