The latest addition to the Tungsten brand, manufactured by Armament Systems and Procedures, is the rechargeable Tungsten USB. When low on battery power, simply plug it into any laptop computer or micro USB-compatible cell phone charger. It comes with a retractable cord, car charger and wall charger. However, the lithium-ion battery should provide a couple hours of power before needing a charge. MSRP $105.
