"The mPower Reserve Battery offers an unprecedented minimum shelf life of 20 years and has an immediate activation to full power. Through an intricate battery design, mPhase developed a way to eliminate power dissipation before initial activation."

The flashlight uses an intense, high-performance LED, and has an accessory USB connection to charge your mobile devices. It's slated to arrive in March, but we hope to get a better look at it at CES in January. [CNETand Yahoo News]
