I bought mine as a father's day gift for my dad who is a truck driver. I noticed he just had it sitting around the house for a year so I took it because during winter my tires get low. Well now I know why it never used it. It doesn't even work. I had my boss try to help me figure it out and he said it was definitely defective and non working. Sam's club would not take it back

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.

We purchased this power starting to keep in our garage. It will discharged itself while not being used in less than 3 days. The compressor never worked properly. No matter where you look at reviews of this product, they are universally bad and all complain of the same issues. How is this product still sold? I’ll never buy a Stanley product again.

This unit worked when I first got it a couple years ago but went to check the charge and nothing worked. I plugged it in to charge and then the screen came alive and showed that the battery is fully charged. I could get everything to work while plugged in but nothing worked as soon as I unplugged it and tried to run off the battery. Absolute junk.

I've had one of the two I own for over 4 years and its still going just fine. I do not keep it in the truck year around. The extreme heat and cold will damage the battery . I know its a pain, but its best to leave it in your vehicle only during mild temps. Long term storage in your vehicle will shorten the lifespan and shorten it fast...Other than that, its great. The compressor is fast and not too loud. LEDs are very bright, and the charge is good for a bunch of jumps

Bought it about a year ago. Used it to few times to fill the tires in my car and now it doesn’t work. Tried to jump start a car today after it was charging all night and it will not do it. Complete piece of junk. Had to use my car to jump start the other one. Warranty is garbage because you have to pay for the shipping. Waste of money.

I bought it from Sams Club a few months ago and I hadn’t had to use it until lately I got flat tires and used it couple times to fill up my tire and the compressor broke. Won’t do the job I’m trying to return it go with something else I don’t recommend it

I needed my Stanley for an emergency and attempted to use it to charge a simple iPhone by plugging it into the USB charging port. The light will come on for approximately 20-30 seconds and then cut off and no longer charges. I have to continuously keep turning on the USB power button in order for it to charge for seconds at a time. This is ridiculous. This feature is a waste.

We looked at this in the store years ago and a shopper observed us. She stopped to tell us that we needed to buy it as it is wonderful. She was correct. My husband uses his constantly to help others with car battery problems and no more having to go to the gas station to put air in low tires. We bought and gifted four more of these and my husband now wants another one. I do not understand all the low reviews.

Does not hold enough charge to jump-start my Audi 2.0T. Found it the hard way: my battery was dead at night, at the PIT airport parking, after being there fo 20 days, and this unit was only able to power up 2 or 3 turns of the starter motor. I did fully charge the Fatmax just before leaving, and its battery indicator showed full charge, so again DO NOT rely on it. Thank you, instead, to the fabulous PIT airport parking service for helping me with my car.
