Stanley needs to stick to tape measures, hammers, and tool belts. I bought two and gave one as a gift. The tire gauge went out after about 3 months, so I have no idea what the pressure is. The charging works but that's it. The "gift" was hardly used, and the air compressor does not work at all. Worthless. I would not buy this.

I've had it for about a year. The air compressor only works once before failing. The plastic gear stripped out inside of the compressor motor. next the LED screen came unattached and became unreadable. but as far as jump starting the car it has worked several times.

A heavy non functioning object.... Air compressor is very poor, and the Battery Start strength is almost non existent..... Tested and tried to use several times before I gave my $99.00 Stanley to my neighbor who fiddles with junk... Bought it because of the "Stainley brand value".. Usually is good.. Not this heavy junk.. Too much going on in it maybe... Bought an Audew online about a 1/4 of the size and comes in a zipped case.. Works way better than the Stanley.. I have a Craftsman air compressor that I bought 4 when they were on sale for like 12 bucks.. Gave them to family.. Everyone loves them... Again I am very disappointed in the Stanley... I have many more Stanley products that are just fine.. But not this item.. I wanted to return it to sams.. but no... so lost a hundred dollars....

Brought it home and started the car immediately. I appreciate the capacity and size of the built in battery. It should be noted (and this is kind of a big negative for me) that the inflator is not a screw on Schrader valve attachment, as shown in the product photo. It's a lever locking chuck. Not a deal breaker but I really prefer the screw-on version. Not sure I would have bought it if I had known.

Power station works well to air up tires, including setting tire pressure PSI to turn off when reached. Works to charge cellphones. Works to jump start battery on lawn tractor. Fails at jump starting a car. Two different occasions to jump start two different cars and would not produce enough power to start other vehicle.

I love this, it's very handy and easy to use and carry. I wish I could exchange it because I have one issue. I'm not sure I can. I've had it for a few months and the buttons have broken, I can't adjust them. That's my only complaint. I definitely recommend this for everyone!!!!

Wouldn't start my V6 bmw even after leaving it hooked up for over and hour.

Easy to use, good price, lots of goodfeatures

Works great. Much nicer than having to lug a bigger compressor and power cord. Definitely worth it.

The short story is: I would not recommend these. After owning two of them three years, I just returned both to Sam's Club this afternoon. To solidify my disappointment, the woman at the return counter said "you have no idea how many of these come back", which unfortunately, made perfect sense to me. The long of it: I owned two of these for about three years. We needed them a total of 4 times. Every, single, time... Every time it did not work. It either would not turn on, or said it had a dead battery (even though it was fully charged 2 weeks prior), or some other issue. I'll break it down in categories without bias to give the benefit of the doubt, since it really does have some neat features and had great potential. Portability: 2/5 It's rather large and heavy, and doesn't have a great handle. Or, at least the handle that's there doesn't work for my hands so I end up carrying it with two fingers through a loop. Many jump starters I've used are roughly the size of a thin book, which carry either in cases or with one hand. So, I wouldn't take it with my anywhere... It's a "stay in the car" kind of item. Which is fine, as that's what it is touted for. Features: 4/5 Without going into durability, or reliability, the features offered are pretty great with a few exceptions. It has an air compressor, for inflating tires, along with a pressure gauge. That is super handy if you get a low tire dummy light, or just need to top off when you're out. It also has a USB charging section, which is helpful for camping or a multitude of other situations. With that said, this is always in my car, and this item is too heavy to carry, which means I would only use the car to charge, but that's beyond the point. It also has a feature to check the battery health, and while the car is running do an alternator check. These are handy features for high level debugging, but an expert needs to look to really make any diagnosis worth believing. I took a star off here because some of the features are strange. For example: the USB charging needs to be turned on and off with a toggle button that is right on the front of the device. It makes a loud beep sequence when turned on, and if slightly pressed (like if it rests against anything in the car... Because the button sticks out of the front of the device and is easily hit...) then it will beep a lot in the back of the car and make you wonder what is happening. It also has a light, which is great, though I didn't end up in any situation where it was necessary, as I said the unit it heavy and bulky, so hanging it over an engine bay as a flashlight doesn't exactly make sense. Reliability: 1/5 This is my own personal experience, but every time I needed it, this thing wouldn't work. One time (4th time I tried to use it) I stopped when I saw someone with their hood up. I pulled out the device and was finally able to get it turned on after whacking the top of the case a few times, then it showed a 1/4 battery indicator, even though I had just recharged it a few weeks prior. Well, I wasn't certain if that meant the device battery, or the car .. so we proceeded (all of the display and lights were on for the device). Well, she couldn't even crank the engine enough to start. It would barely turn over the V6 in their Toyota 4Runner. Another time I stopped to help someone else with a dead battery once, and the Stanley just wouldn't turn on sitting alone, it wouldn't turn on when hooked up to the car, it didn't do anything. When I got home, I figured it was dead, so I set it on my workbench and turned the switch and nothing, so I gave it a whack on the top and it out up, full battery on the display. I was bummed I had to leave that person waiting hours for a tow truck. Overall: 1/5 In general, I'd never buy this again. I guess I should have known that the company that makes hand planes wouldn't make a good car jump starter, but it just seemed like such a great package! It was also so big and robust I figured it would have a large battery that would work for a long time. Very disappointed.
