Having a Portable Jump Start handy around the garage is a great idea. But combine it with an air compressor to fill up tires, and you've got a useful tool to get you out of numerous situations! Honestly, I've pooh-poohed these things for years until one day when I would have traded my 1970 Fiat Dino for one. (The battery was dead... again.) Now, no matter how dead the battery is, I can jump start the Fiat and be on my way. Fiat saved! This 1,700 peak amp starter will jump start your car up to 20 times between charges, and includes its own battery status meter. To recharge the unit, just plug it into your 110 volt outlet with an extension cord. Has a 12 volt DC outlet, so you can recharge your cell phone when the power is knocked out for extended periods of time! The jumper cables are 68" long, allowing you to place the jump start on the ground and still reach the battery terminals! The air compressor has a 12' coiled air hose with a screw-on chuck so the fit is tight. This is easily the nicest Portable Jump Start and Air Compressor on the market. Enjoy the best!
