Great idea for a tool but poorly done. I’ve purchased 2 of these and seldom have to use except for compressor. I’ll say it is handy to have. Starts car when battery cable won’t. But the compressor in the first went out after a year. The second one went out on the third use. Too bad because this is a good tool but breaks too easy

I bought this in March of 2021 and it worked well for about 2 years. Over the past few months, it has grown more and more erratic and just shuts off randomly. It doesn't even turn on most of the time and I'm not sure if it is the battery or something else. It indicates that it has a dead battery but I've charged it endlessly and it never gets full. I would advise buying a different product that has a removable battery since if this one goes you're stuck. If there is a warranty or process to fix this I would be interested but I haven't been able to find any information.

I bought this for an easier way to jump start my riding mower and occasionally top off the air in one of the tires. I've used it 3 times to jump start the mower and it worked great. Used it once to put air in a tire. After last use, I charged it up for next time and put it away. A couple of weeks ago, I heard a noise in the kitchen when I got out of the shower. The dang air compressor came on by itself and it wouldn't turn off, nothing worked. I took it outside in case it overheated or something. It ran until the battery went dead and the compressor shut off. I plugged it in just to see what it would do and it wouldn't even show it was trying to charge. Now to see if Sam's Club will take it back. The last one I had came from Harbor Freight and it lasted over three years.

I purchased this hoping for the best. Following all the instructions with charging, tried to use it to fill up my tires and it was dead. When I would plug it in, the LED screen would work, but then stop as soon as unpluged. I returned and would not recommend. My Craftsman that I purchased 10 years ago is still working great.

Too heavy, too cumbersome, designed with too many circuit parts and places for failure. Would not recommend to anyone. You have to maintained it charged every other month, cant leave in warm/hot places (eg. garage), can leave in cold places (eg. garage). Check YouTube to see the problems people have had and how they fix them, that will convince you not to buy.

This junk box works great only issue I have is that it does not come with a charging cord for it but I was lucky to already have one from my previous jump box. The compressor on it works great for somebody who doesn’t understand the compressor well The digital tire pressure gauge built and it works awesome for setting The compressor to the proper pressure and starting up once it reaches The desired pressure it will shut off it has not failed me in over two years of ownership also having the USB ports on it comes in handy and does not drain the battery much overnight when in use I have Taking the jump box camping and used the USB ports and for overnight charging of device while camping

This thing comes with no cord for AC. Only two male prongs to plug an extension cord female end into it mounted to unit body. I hooked it to a small air tank to see how high it would actually pump pressure. It was flat out stalled at 62 pounds, with no further increase after several minutes. I don't want to give the other one I bought as a gift without a cord. Nice looking with a good shape would be the good things I would say about it.

I bought this thing couple years ago only used it couple times, always kept it charged up, I thought but it never would charge to full compacity the charging indicator would always blink like it was still charging after two days of trying to charge it. I send It to the recycle dump. The Stanley fatmax has never worked like it should would NOT jump off A dead battery in A vehicle. It's not worth having that's why it in the recycle dump.

The jumper charger works well as advertised but has a couple of significant issues. First the cables are very short, especially considering the width of the unit. This is the third jumper I have had in the past 15 years or so and it has by far the shortest cables which results in someone having to be with the jumper when starting a car so the unit does not fall. Second, the four USB ports are not covered which pretty much precludes using the jumper in rain or snow. As we live in Minnesota this severely limits it’s usefulness. I have pretty much decided to return it because of these limitations.

I brought this unit from Sams Club just in case my wife or daughter had a dead battery or something. It always drains itself. It will not keep a charge. Its to expensive to ship to manufacturer. Its a big fat dud when you need it. And a total waste of money!!!!!
