This thing is the "Cat's Meow!"   I use it all the time, around the homestead, when camping, everywhere.   always with me.  use it to keep all my tires properly inflated.  have jumped off several vehicles in need.  charge a phone.   even check the Alternator.   There are probably others out there, but this is one of the best utility items I've ever bought.

This jump starter works well and the air compressor does it's job too. I have used the compressor on golf carts, lawn mower and automobile tires. It is a lifesaver if you get a nail in your tire and carry a tire repair kit in your trunk. The unit works as advertised and I am a satisfied customer.

Had for a couple of years, barely used for jumping, 3rd time using, wouldn’t power off, recharged, wouldn’t jump, no power to cables, still wouldn’t power off but held charge so it beeped insistently for days. Finally charged back up thinking it was a fluke. Nope, no jump, air compressor never tried doesn’t work, usb works, but won’t turn off, so other than a battery charger for phones, it’s useless.

The unit looks good, the led's are bright and it has the feel of a heavy duty unit. I haven't tested the air pump on tires yet but saw that a few people complained about the pump's short lifespan. All of my previous portable jumpers had a cigarette lighter plug, so I was surprised that this model did not. It's important to me because my 120v inverter is powered through the cigarette lighter. This unit also doesn't come with a charging cable which you have to buy separately.

I bought this on 12/29/19. I charged it up the day I bought it. There it sat, quietly, anticipating the day it shall be called upon to fulfill its duty! Today, 12/5/2020, the day has come. Duty calls! First time for this little unit to shine and satisfy its destiny.... sadly, it fizzled out like a bad firecracker. I had low tire pressure in my Jeep and I tried to use this power station to pump up the tire. I was truly excited to use it.... I liked the features, I pressed the "tire pressure" button and after connecting the built in hose to my tire, it told me I was at 26.5 PSI (which is what my Jeep dashboard told me). I set the PSI to 32 and pressed the "tire pressure" button again to begin filling and just like a bad video game death... the motor kicked on but after 2 seconds it cut out, the 'drained battery' indicator was flashing, and I was left without an inflated tire. I had even charged this up yesterday anticipating using this to pump up my tire. Sadly, the battery is junk and after reading other reviews, it seems this unit is plagued with other issues too. I WOULD AVOID THIS UNIT. Now I am left trying to find a satisfactory replacement that doesn't have "Stanley" in the title.

The USB Ports do not work; they power up, but shut down immediately when you attach any USB device; I have tried phones, speakers, and many other USB items simply to charge; none draw more than the 3.1 amps and I have not attached more than one device at a time; there is nothing anywhere to be found on how to trouble shoot why; I have used many different cables also; this happens with every USB device I attach to charge.

I do wish I would have read the reviews 1st! It doesn't work like I thought it would when I bought it. But I'll take the loss for not doing more thorough research beforehand. But the thing doesn't even do what it's supposed to do. It doesn't charge batteries very well. I doesn't pump up tires very effectively. I have to search for some type of instructions online every time I use it. It takes longer to charge it than it does for it to lose the charge when it's not in use. It was a terrible waste of money and I'll admit I'm very upset about this purchase, considering I had regarded Stanley and at least a decent product manufacturer.

I purchased one last Feb. of 23, I used it one time to fill tires, not more than 10 minutes. My jump starter, attempted to jump a vehicle after a full charge, but with no luck. I tried to fill my sons tire after plugging his tire, but cut out immediately. Did research, checked o ring and looked for leaks, o ring was fine and couldn't find any leaks. Save your money, buy a different unit.

I have purchased 2 & at different times so I am apt to believe either workmanship or parts changed as the older one works well while the newer one does not retain a charge. Emergency equipment that is not dependable is not an assured feeling for a product.

Bad product. Don’t buy it. My kids got it for me as a gift Worked once to pump a trailer tire up . Now display,lights wont even turn on unless a power cord is hooked up, as soon as I disconnect the power cord it turns off . Says the battery is full and @14v . There a little engine symbol on the bottom right corner flashing. Now that I read all the reviews here there iis definitely something going on with these units .
