I'm reading the reviews and people think it's a 12 V DC to 120 V AC inverter, battery charger, etc. It's not. It is a jump starter in case your car/boat battery is dead; air compressor if your tire is down; and it is a small, compact 6 plug usb charger. That's it (can't forget the eye blinding LED light that it has). Well worth the $69. I bought 3 of them. One for my boat in case I run all of the stuff (charging the phones, stereo and amps, kids charging their ipads, etc.) too long while on the lake and can't turn the engine. 1 for my camper for the same reasons and 1 for my truck in just in case any of the above happen and I need a jump or air in my tires. Come on people. It is really lightweight and has a rechargeable battery that you use an extension cord to recharge. You don't even need a 3 prong extension cord to recharge it. $69 at Sam's for a peace of mind.

Received this as a Christmas present a couple of years ago. We use it all the time. Have used the compressor on an older model car that we didn't drive often and had to add air to the tires every week or so. It has been a lifesaver in the neighborhood for jumping dead batteries at the worst of times and have even connected to our tankless hot water system for the ignitor during power outage! So happy we have it!

Only have had it a few days but found out it will not inflate anything with a valve stem. Air line does not depress the pin in the middle of the valve stem allowing air to pass through the valve stem. As soon as you try to use the compressor with a valve stem the compressor shuts off because it is only compressing the air between the compressor and the valve stem. Do not know if other Fatmaxs have the same problem.

If you buy this product then you better get the Allstate protection - IT WILL DIE. Used 2 times, stored in a climate-controlled garage, no longer works, battery shows less than 8v when tested, refuses to charge. This item belongs to a professional electrician and electronics expert so HE knows what he is doing (despite the store questions).

Have purchased 5. All of them had pump burn out while trying to air up more than a car tire (SUV, pick-up, or trailer). Battery doesn't hold charge after a while. One died in a year, the others varied. I wanted it to be good. That's why I chalked up the 1st two failures to neglect or lemon's. But after buying 3 more...

Purchased yesterday at Sams Club when wife called and said her car wouldn't start. Had been considering one for some time -- took it out of box when I got home and already was near full charge. So connected it per instructions and car started right up without a problem. Recharging now and will then have on hand if any further need arises. Thank you Stanley products

Lasted only one year. Compressor died and battery died and doesn't stay charged. With full charge, it is not enough to get the car started even once and the battery immediately goes to zero. Used only a few times. Sad that when you need it, this would let you down. This is my 2nd Stanley product. The previous one also only lasted a year. Look elsewhere.

I bought this unit from Sams in March 2019. It is a bit bulky and heavy but I like it when it worked. I used it a couple of times to jump start a car. I used it more for airing up low tires. One Wednesday it worked on Thursday next it didn't work and will not take a charge. None of the controls operate and when trying to charge, the LCD window is blank. When working it lights up with voltage and a bar that indicates charging. It has a 1 year warranty but shipping the unit back to be repaired (they don't pay return shipping) costs so much that you might as well by a new one. But NOT this one. Anyone with Ideas on how to make it work let me know.

I'm seeing reviews from persons who think this product failed on them. But there are things to consider here. It is a battery operated device, used for jumping vehicles and airing tires. It is a battery operated device that will lose its charge when sitting in a car, without use, for months. Especially in hot and cold environments. So, every 3 months, take the unit out of your car and charge it to capacity. Doing this will ensure you have a fully charged unit, ready to go. I have had 3 similar units and only one had failed to jump my car...but it was also 4 years old. Take the recurring charging requirements into consideration when you purchase this.

The previous model that I had was great. I could power up to 4-100 watt lamps, and did so as a test. One day I came home and it was flashing, the compressor was going. I had to take it apart to disconnect the battery. Got this newer mode l and it's even worse. The compressor won't inflate ANYTHING, the backlight won't shut off and it cycles through modes. All this started after the time I had to return it to Sam's club DON'T WASTE YOUR TIME OR MONEY FIND ANOTHER BRAND LIKE SMARTEC- JSL-950 IT HAS AN A/C OUTLET ON IT.
