Seems like the U.S. Army had a bit of an “oh shit” moment when they realized that they’d need a lot of juice to keep their “soldier of the future’s” electronic kit powered-up. Because the military can never have enough acronyms, or rely on easily available, low-tech, locally scroungeable solutions (i.e. AAA batteries), they’ve developed SWIPES (Soldier Worn Integrated Power Equipment System). “The conformal, lithium-ion battery and docking system made by Arotech which received an initial order from the Army for 350 systems in February, reduces battery weight soldiers carry by up to 30 percent because only one battery will be used to charge radios, night-vision goggles, GPS units, shot-detection systems and smartphones,” armytimes.com reports. “It charges only those systems that need it, when they need it. The battery that supplies the energy weighs about two pounds.” Want one? Two? Three?
