The Three Year Jump Starter

This is the reliable automotive jump starter that stays charged for up to three years. It instantly starts eight-, six-, and four-cylinder engines, and will hold its charge for three full years between charges, far superior to other models that require frequent recharging. In tests by the Hammacher Schlemmer Institute, it jump started engines even after it was frozen to 17° F, so you can rely on it when you need it most. Weighing only 1 lb., it is nearly as small as an iPhone 6 Plus, and stores with the included cables in a zippered bag that fits unobtrusively in a glovebox, unlike bulky jump starters that require dedicated trunk space. It also has two USB ports for recharging laptops or cell phones, an integrated flashlight, and an LCD to indicate remaining charge. 6 1/2" L x 3" W x 1 1/2" H. (1 lb.)
