And even if you do have a charger with you, what are the chances you'll have a place to plug it in? The entire point of carrying a smartphone is to be effortlessly wireless, and now big brands, like Kate Spade, are finally embracing the benefit of creating products with built-in chargers. This is a somewhat bold move for a huge designer brand like Kate Spade, but the company's Executive Vice President and Chief Marketing Officer, Mary Beech, said they're "committed to digital innovation," and designing for "customers who live a life on-the-go." Kate Spade will offer several types of bags with Everpurse's embedded charging technology. The collection will includes a $198 wristlet, a backpack and tote that cost about $400 each and a "top of the line" tote that costs about $700. This partnership represents a shift from Everpurse producing their own line of bags, to instead partnering with companies to license out the technology. The Kate Spade bags are expected to be available by fall.
