Let's face it, phone and car batteries die more often than we would like. Now you can power up both with the Cobra's JumPack CPP 8000. Small enough to carry it with you anywhere you go, easily stowing it away in a handbag, briefcase, or even a pocket and weighing in at just under 10 ounces. It's one of the most compact and portable power packs while offering dual capabilities of mobile-device charging and vehicle jumpstarting, including a range of cars, SUVs, motorcycles, outboard boat engines, etc. multiple times. With a form factor that is 40 percent smaller than its predecessor, the CPP 8000 is a great companion for travel, outdoor, safety, and multi-purpose use. The sleek and attractive model offers added built-in protection circuitry including short circuit protection, reverse charge, over-charge, and reverse polarity protection. This unit holds approximately 85 to 90 percent of its charge for up to eight months. The Cobra JumPack has the reliability, versatility, and convenience you want in the tiny package you need.
