Forget that big, heavy lead-acid jump starter device!
June 10, 2015 
The folks at Cobra have been making car travel gadgets for a long time. But I’m particularly impressed with their new JumPack device. Cobra says you can use this small, lightweight device not only to charge your mobile devices, but also to start your car when the battery under the hood won't! It packs 200 Amp Starting Current, 400 Amp Peak Current, which they say is enough to jumpstart most cars, even those with V-8 engines. And you can jumpstart your car multiple times on one charge. I carry one of these on my boat, waiting for the day I need it. The day arrived when I came down to my boat to find the battery that starts my 225hp Yamaha four-stroke, dead. (Yes, I have a battery for the bilge pumps isoldated from the starting battery.) I hooked up the Cobra JumpPack as instructed, hit the key, and by golly --- my engine started up immediately! Wow, no more lugging that lead-acid battery-up device around. It was usually dead when I needed it anyway. Besides starting boat and car engines, the JumPack also has a 2.1 Amp USB port to rapid charge your portable devices including cell phone, smartphone, tablets and other mobile devices. But wait, there’s more! There’s a built-in superbright LED flashlight, plus strobe and S.O.S emergency blinker. 7500mAh Lithium-Cobalt Battery. Unlike a lead-acid battery jumper device, which loses power quickly, the JumPack will hold 80 to 90% of its charge for about a year. The device is about the size of a small paperback book (5.04” H x 2.87” W x 0.98” D) and weighs only 11 ounces. It comes with a 12-volt cigarette lighter plug charger, 110-volt charger and jumper cables. Charging or recharging the JumPack takes just a few hours. Model CPP 7500. MSRP $129.99, but you can find it for under $100.
