Amsterdam-based entrepreneur Marijn B. Berk and bag designer James Jeffrey are working on an interesting product: A bag that not only carries your laptop, tablet and smartphone, but can charge all of them up. Called Phorce and billed as "The world's first smart bag," the rectangular satchel boasts unseen, on-board power that can charge up to three devices at the same time, via built-in cables.

That's the power part; as for the smart part, the bag itself connects to your smartphone via Bluetooth. With this enabled you can set an alarm, so if you and your bag move a certain distance apart, it sounds. That won't help you if you leave both in a cab, but if you walk out of a meeting with your phone and absent-mindedly left your bag behind, it'll let you know before you hit the elevators.

Beyond the techie stuff the bag has well-thought-out physical design features: Expandable sides, waterproof zippers and fabric, a strap system that converts the bag from backpack to shoulder bag, and magnetically-clasping dual handles for a briefcase mode.

The slickly-produced Kickstarter video is here, but I actually found their more raw YouTube video provided a better look at what the bag can do:

At press time the Phorce had surpassed its target, garnering $171k of $150k, and pledgers can still snag one at the $119 price until December 22nd.
