La CES 2013 some interesting accessories were presented, however Brookstone Nectar it definitely falls into the category of the unusual. The device promise to charge our iDevices without using a power source, but to do this it uses energy cells that cost $10 apiece. These cells have the capacity to charge an iPhone approximately 10 times, theoretically offering 2 weeks of autonomy, according to the manufacturers. The device itself costs $300, and the energy cells are $10 each, but what they offer is really interesting.
nectar™ is the world's first truly portable power system. After inserting a pod, any USB 2.0 compatible CE device can have 2 weeks to a month of mobile power. Unlike other back-up batteries or recharging devices, nectar does not need to ever be plugged into a wall outlet. Today's consumer electronics devices are more power-hungry than ever. A dead battery means important missed calls and emails, no GPS when you're lost, no e-reader on your train ride, no communication in an emergency, and an overall feeling of dread and anxiety. Lilliputian has the cure, nectar™- the world's first truly portable power device that will power all of your CE devices for up to a month with a single power pod.
Most similar devices are available at similar prices, Brookstone Nectar it differs only in the way it provides energy, but at the price of $300 I don't think there will be many people interested in it.
