This Tiny Phone Battery Can Also Jumpstart Your Car
(Or charge your phone.)
Forty percent smaller than its predecessor, Cobra’s pocketable new 9-ounce, 5 1/2-inch tall JumPack ($120) is brimming with power. Its 180-amp starting current and 360-amp max is ample enough to crank up your car, motorcycle, SUV or outboard boat engine. Since it holds 85 to 90 percent of its charge for up to an impressive eight months, it’s a great little (roughly phone-sized) item to throw in the glovebox until you need it. But feel free to whip it out any time along the way to safely charge your mobile device. Oh, and it also has a built-in LED flashlight, which is always handy.
