By Evan Ackerman Remember the Airnergy WiFi power harvester that we showed you last January at CES?

New Lithium Ion Batteries Increase Lifespan To 20 Years
By Evan Ackerman Lithium ion batteries are way, way better than nickel metal hydride batteries or (shudder) nickle cadmium batteries.

USB Camera Battery Charger Isn’t As Cool As It Could Be
By Evan Ackerman This looks, at first glance, like an incredibly useful charging accessory: it plugs into a USB port and has adjustable teeth to charge any of those blocky, unfriendly, proprietary custom camera batteries.

OhGizmo! Review – Mophie Juice Pack Air
By Chris Scott Barr iPhones aren’t known for their excellent battery life. In fact, they pretty much need recharged every night just to make it through the next day.
