After having it for six months it keeps turning itself on and off. Whether it is the led lights or the air compressor. It turns itself on and off as it pleases. At least it causes the battery to die when not in use. At worst it can be a fire hazard I would presume.

I may have gotten a defective product but this is not a product you will use offten. When i did need to use it it qas never charged although i had charged it. This product has an on off switch but even in the off position it remained on. I believe that is why it could never keep a charge. By the time i discovered it was defective the warranty had expired. $90 down the drain.

Literally bought two about a year ago. One for me and one for my daughter and both only worked a few times and now neither one will charge. Very disappointed because I thought we both had the security of these machines if we were ever stuck and now neither one works.

Used the compressor for zero turn mower tire that was low and it worked great. Now I have problem with it turning itself on in the "alternator check function" and it will not stay off. My limited 12 month warranty is past and there is no manual to check if this is a minor problem. Had a similar charger/compressor with no problem for years and gave it to my dad who still has it. Extremely disappointed.

Bought 6 months ago. Not used very frequently. Charged this week and backlit display Wii not turn off so the battery is continually draining. Charged to 13.1 bolts a couple of days ago. Today, with no use, it's down to 12.3 volts. Why have a portable jumper if it has to be charged weekly?

I have jumped vehicles off, used the usbs and light while camping, air up my tires as needed, checked battery and alternator. I love it. I have been using if a couple of years. Battery doesn't hold a charge as well as it used to but dtill works well. Jusr charge more often. My parents had one for a short period of time and the compressor failed. So it seems like some are good and some not so much from the other reviews.

I love this jump starter. I've used it several times from charging my battery to airing up my tire and have had to re-charge it yet. I would have giving this a 5 stars but instead I give it a 4 because you have to buy an extension card to charge it up.

I have had this product just a little over a year and just as I’ve read by many others, the FatMax 1200 quit charging. When I was stranded with a flat tire, it was dead & useless. I brought it home to charge and although the screen stated it was completely charged at 14.0v, I tried to use it and it wouldn’t turn on at all. I’ve used it a handful of times but being that I travel much by myself, thought it would be a great tool to have… greatly disappointed!

Was a little surprised as to how well this unit works for the price. I had been looking around for a good unit for about $100 could not find much with 1000/500 amp then thought of Sam's Club just for the heck of it. Wow, we have used it a few times this week all ready. Will recommend to friends.

I purchased two of these one of which would not charge. I contacted the company because it's under warranty. I was told that I had to ship it back. I went to the post office to do that and it was going to cost me almost $40. I did my research before purchasing this and it had great reviews. So buyer beware if anything happens to it it's going to cost you half of what you paid for it to return it I would not recommend
