Logitech's 'case+' modular iPhone case system lets users swap out add-ons

With the case+ system, Logitech is looking to bring together a few standalone products made by other third-party case vendors into a cohesive and integrated collection.

As seen above, the case+ acts as the system's base element and incorporates an exposed metal back plate that serves dual roles as added protection and a magnetic mounting point for the accessory add-ons.

In all, Logitech is bundling four attachments in its case+ collection, the first being an external 2,300 mAh battery called the +energy. As seen above, the battery pack simply snaps onto the back of case+ and delivers power via a U-shaped Lightning connector. A fuel gauge is incorporated into the rear shell and looks sport a Micro-USB port for recharging.

The +tilt almost looks like a miniature Apple Smart Cover save for a large cutout to accommodate the iPhone's camera and flash. Offered in two different cover materials, the +tilt features a magnetic mounting system that attaches a connected iPhone to nearly any metal surface. Users can also transform the cover into a kickstand for video viewing or wrap their headphone cable around the phone, locking them in place by folding over one of the tri-panels.

For an in-car mounting solution, the +drive is more of a standalone product than an attachment. With a twist-to-lock suction cup base that can latch onto a windshield or dashboard, the car mount features an articulated head onto which an iPhone with case+ can be attached. A universal adapter is also included for use with a second smartphone.

Finally, the +wallet lets users carry credit cards, keys and cash on the back of their phone. Logitech claims the unit's "Magnashield" technology will block the case+ from demagnetizing cards with magnetic strips.

Logitech's case+ collection includes all "+" accessories and is slated to go on sale in the U.S. later this month for $200.
