I have owned multiple versions of this product. This one by far has corrected a number of issues with the proceeding versions (power plug connection and faulty tire inflator). The AMG batter inside is one of the best on the market for cold cranking amps and durability. Very please with the enhancements to this model.
My mom purchase one of these for everyone in our family, 6 total batteries. Right out of the box one didn't work at all. The display read some error message. I used one reliably for about 1 year then one time I plugged it in and the display wouldn't turn off. It would show the battery value till the battery drained. I plugged it in and charged it up, then the battery drained with the display showing the whole time. This one confidently waited just outside of the warranty to fail. Thanks so much Sears. Then I borrowed my moms to use and the first time that one needed to be recharged it read 10 percent after hours of charging. I currently have 3 of these at my house that have all failed. And none of them failed because of battery misuse or even dead batteries. All told each dead battery went through approximately 3 charge cycles each. What seems to die on these repeatable is the cheap controllers they put in these things. I have not contacted Sears about repairing these yet but Why should I give them more money for a product that is basically a scam. If you buy one of these things just rememeber your playing russian roulette with the batteries life everytime you think to use it. Go with some other brand because these are high priced junk.
Great product. I have already used this several times since my purchase. I've used it to jump off a car as well as the air compressor to fill up bicycle tires for my daughter. Very hand to have on hand.
It does everything I need it to do. I love the 2 12v and the 2 110s it works perfectly and I'd recommend it
