This is an amazing invention. I bought this when my battery started to go out. Luckily, I was able to replace it pretty quick, but I ordered it in the morning for same day delivery and had it within a few hours. The next morning, my battery needed to be charged and it gave me a chance to test this jump starter to see if it was worth the cost. I have a Ford Explorer (insert Ford jokes here) and it's a bit of a beast to charge and jump but this worked out of the box to jump it. I had to use it twice more that day because the battery wasn't holding a charge and it worked perfectly to get me going without the embarrassment of being stranded. Additionally, what makes this a 5 star product is all the extras. There is a compressor built in it that I have not tested on my SUV tires thankfully, but I have used it for all my kids bikes and it works great. It shows the pressure and aired them up quickly. The small flashlight came in handy when I was jumping the car at night and didn't have another flashlight. Even if I did, I prefer this one since it's attached to the device and I could shine it without holding it in my hand. Somehow, they just said "who cares" and added in a USB charger so I have a massive battery pack as well that I can charge anything from small handheld electronics like phones to laptops and car vacuums. It's amazing. Finally, here are some features that I love that are just icing on the cake. It's very compact which allows me to keep it stowed in the back of my SUV easily. The handle on the top seems sturdy and it feels like a metal construction. The fact that all the tubes and cables wind up onto the device make it very convenient. The tester that tells you how much juice you have is great to keep it topped up as needed. I feel safer having it with me in the car knowing that it can help take care of me in a pinch.

I purchased this originally to use with my landscape business JumpStart zero turn and walk behind mowers. Since then I found that I use it for just about everything under the sun. It has plenty enough juice to jumpstart a jeep that I've been working on as a project five or six times before it needs to be charged. With my zero turn and walk behind mowers I can jump start them a dozen times easy. Surprisingly enough the built-in air compressor works pretty well. For small tires like zero turn mowers, wheelbarrows, bicycles, dirt bikes and so on the compressor works great. I've even used it to top off the air pressure in my Mazda RX-8 that requires 50 psi cold anything below 40 and the light comes on on the inside saying low air pressure. Now what I try to inflate a 33" mud terrain tire, no but for everything else including slip and slides it works great. The built-in USB ports are nice to have but I've never really used them. Even though it would be nice if the battery charge lights had two or three more in total would be nice to give you a better overall idea of how much charge is available. I will say one thing that I despise about this product the stupid flashlight! For one it's not that bright and number two is its location. The way they have it situated the button that turns it on is on the underside right where you wrap the cord so if you're not careful you can accidentally turn the light on and if this happens during the daytime you'll have no idea that a flashlight has been activated until you go to use it the next time and the battery is completely dead because said flashlight remained on until it killed the battery. I purchased this in April of 2020 and it's now 5-28-22 so just over two years of use and I would say that I've used it easily 60 times and it's never let me down. As I mentioned before I jump-started things as small as lawn mowers but I've also used it to jumpstart Jeeps, Mazda RX8, Ford F-150. If you've been on the fence about buying a jump box and being concerned whether or not it's worthwhile investment believe me when I say the Stanley box is freaking awesome. If you go to my Amazon profile and read some of my other reviews you'll know that this review is sincere because if I find anything wrong with a product I have no problems with pointing it out. Also know that my last jump box I purchase from Harbor Freight and while it was supposed to be about the same amps is this Stanley the CCA was way lower and I would be lucky if I can jump-start two or three zero turn mowers and never even tried using it to jumpstart a vehicle because I knew it wouldn't have the juice I just figured I'd save the time and get out the jumper cables. Someone stealing the Harbor Freight version out of back of my truck was probably the best thing to happen to me when it comes to portable air compressors and having a decent air pump it's just a nice bonus. My only other advice would be to snap the flashlight off and cut and cap the wires otherwise you will find yourself with a dead jump box because the stupid flashlight was accidentally turned on during the day when you cut a notice.

This jumpstarter is absolutely amazing. I mean it. My car has had it's battery die on many occasions, due to a variety of circumstances. I have never had a problem with it in it's extensive use. Trust me, this thing takes a lot of abuse from me. It sits in my trunk 100% of the time, unsecured, in freezing cold temperatures, bounces around, and gets very frequent use (anywhere from daily use to once or twice a month). I bought it on November 6th 2014, and at the time of writing it is Febuary 2nd 2015. I haven't had it for long, but I have definitely used it more than anyone should have to use one of these. And it still works just fine. The cables and alligator clips seem very sturdy, as well as the materials used for the casing, handle, and various switches. It is very reliable. I would wager that it is more reliable than my car's actual, brand new (November 2014) battery. Now that we have it's sturdiness aside, I'm going to talk about it's performance as a jump-starter. Yes, it does come with some fancy frills, but let's be honest. None of those matter if it doesn't do it's intended job. However, that's not an issue at all, because it DOES do it's job, and it does it very well. My car is a 1988 Mazda RX-7. These have a lot of electrical problems, due to Mazda's poor soldering and 27 years of corrosion on the grounding points. My battery will every once in a while drain for some unknown cause, it leaves a circuit closed after turning it off or something. Even when the battery is 100% dead like this, this jumpstarter can crank out enough power to turn it on. If you try to turn the car on very quickly after connecting it (less than 10 seconds), it might not turn the motor over very quickly. However, if you wait just a few seconds, it cranks it over just as well as a fully charged battery. Basically, when the battery is 100% dead, it takes a couple seconds to build up some juice. Which is fine. Another thing, my car has a strange engine that is drastically different from any other car's engine (it has a rotary engine). These take a LOT of power to crank over. This jumpstarter is more than capable of turning it over. In the winter, it is a common phenomenon that the rotary engines have trouble starting even with their own factory battery, fully charged. They thick oil they use compounded with the high power necessary to start them renders them sometimes useless in the cold. In the winter, if the car doesn't want to start, I just pull this out, connect it, and it'll start faster than ever. It gives a significant boost to the battery, and lets the car start much faster than usual in conditions when it would normally not even start at all. Next, let's talk about charging, battery life, etc. It does not take long to charge at all. There are two ways to charge it, you can use a 12V DC "cigarette lighter" plug (included) and charge it in the car, and it also has an AC plug that you attach an extension cord (not included) to charge from a wall socket. I haven't used the car plug, I have only used an extension cord. It usually has a "green light" in a few hours or less. Granted, I have never fully drained it, I've come down to the first LED out of the 3 that indicate the charge level). This leads into another great thing about it. It can take a lot of use before it needs to be charged. I have had it for 3 months now, and I have charged it about 3 times. This may seem like a lot, but remember, I use it very, very frequently. I haven't actually counted how many times I can use it before I have to charge it. However, when it's very cold out, I use it almost every time I start the car. This shouldn't count as a "full jump" though, because my car battery is actually fully charged. I'd count it as a "partial jump" because it IS using power from the jump starter. It gives enough "extra power" to get the motor started. Doing this, I have never actually had the indicator drop below the green "fully charged" level (or whichever it was currently at). As for completely dead jumps, I tend to mix those in with the "partial jumps". I can't give exclusive data on that, because as is the case with jump starting, it occurs unexpectedly. However, I can definitely perform multiple completely dead jumps on a single charge. Sometimes a full jump won't even take it below the "fully charged" green LED indicator. Sometimes, it will drop down to the 2/3 level. If I had to take a guess, I'd say the jump starter would be able to jump my car (with a completely dead battery) reliably 3-5 times in a row before it can't do it anymore. Maybe even a bit more, if the car battery is not 100% dead, but doesn't have enough juice to either start the car or even turn it over. I have also used it extensively to turn the motor over without the goal of starting the car. Sometimes my car has problems that require turning the engine over without actually starting the car. If you're familiar with cars, I have to take out the spark plugs or fuel pump fuse and crank the engine over. When doing this, if I turn the key, the engine just makes the "brrrbrrrbrrrbrrr" noise but never starts. This kills my car's battery, so I hook up the jump starter once it's dead. Again, I have not collected any hard data, but I do have a general idea of the jump starter's capabilities through frequent use. If I had to give a figure, I would say that the jump starter (from a full charge) can turn the engine over all on its own for a total time of about a minute to a minute and a half before it gets to the first of three charge indicator lights. That is a minute and a half of constant "brrrbrrrbrrrbrrrbrrrbrrrbrrrbrrr". To those who know that doing that for such a long time is bad, this is not all at once, it is spaced out over the period I'm working on the car. In summary, you barely have to charge this thing. It can easily take a couple jump starts before you even have to THINK about charging it. I'm gonna recommend that you keep it fully charged, and charge it after every use. It is definitely unnecessary, but I'm gonna say it just for the sake of saying it. I don't want anybody to get mad because "this guy online told me it would last exactly 4 jump starts! Now it's not working and he's an idiot and I'm stranded!". And it puts out a very generous amount of power as well. Now, the fun little features that it has! It has a USB port that you can use for charging phones, electronic cigarettes, cameras, or even to power your USB desk back massager. I have never actually used it "for real", but I did test it out, and it works. I don't know how long it would be able to power something like a phone, but if you are stranded somewhere, you will DEFINITELY NOT have to worry about your cell phone dying. If it can jump a car multiple times, it can probably power a phone for a very long time. The built-in flashlight works pretty well. You can move it around and stuff, and it can actually really help at night if you need light for something. It's not the best flashlight in the world, because it's attached to a giant battery, but it gets the job done. It's more of an "oh crap I need light" thing than "I'm gonna be out in the garage tonight, I'd better bring the jump starter so I can see!". The charge level indicators are a little weird, but it really isn't a problem. You just press a button, and 1-3 LED's light up to show you how much it has left. I can see how someone would think it's a little inaccurate (you couldn't have put like a couple more lights on at least?), but it gets the job done. You really do not need an exact percentage display of the battery life, and this reduces the cost because it doesn't need an on-board computer to run a display. The last little thing it has is a mini air-compressor for filling your tires. The value of this depends on how you look at it. It is NOT good for filling up your tires. It will take forever. If I'm being honest, you're probably better off going to a gas station and paying a quarter. Even though it's kind of awful, it is still easily my favorite feature of this jump starter. If you happen to notice that a tire is low, you can just fill it up. If you're like me, then it's always in the car with you, and you never have to worry about finding a way to fill your tires. If a tire is leaking air, but is still somewhat drive-able, it will be a lifesaver. You can use this crappy little air compressor to limp your way over to a repair shop (or your house, if you're so inclined). It is a great thing to have in a desperate situation. Now onto the negative things...which there aren't many of. The switch for the air compressor is on the back. Under normal, not reckless use, it is 100% fine and there is nothing wrong with it. However, this thing sits in my trunk literally all the time. It is not fastened down at all, and there isn't really anything else to hold it even remotely in place. As a result, it ends up flying around a lot. Not often, but occasionally, the air compressor switch will flip to the "on" position from a bump, hard turn, panic braking, etc. I would not consider this one a flaw with the product, it is more of a user error. I know I don't take care of it, and it really is a result of my negligence. It is still worth noting though. To avoid this, you have some options. First of all, don't be like that random guy on the internet and let it fly around in your trunk. Second, if you do, place it so that the front (the side with the yellow buttons) is on the bottom. It is much less likely for something to move the switch, because it would have to flip over. If you manage to flip it over AND move the switch while driving like a sane human being, then I honestly think you deserve to have your air compressor switch flipped. Lastly, you could put some tape over the switch or something if you absolutely cannot avoid stowing it recklessly and driving like a maniac. Next issue, the size. For anybody who has a somewhat normal car, this is not really an issue. It may be able to power a car, but it is not the size of a car battery. It is much smaller. However, I have a two-seater convertible that only really has a trunk because it's hard to sell a car without a trunk. It takes up a large portion of my trunk. It is DEFINITELY worth it, but again, it is worth mentioning that with the other various tools I need in there for my ancient car, I pretty much end up with 1/3 of my trunk space available for trunk-stuff. And that's after playing trunk-tetris and getting everything to fit like a puzzle. So be warned, if you have something like a Miata, S2000, or another tiny two seater, space might be an issue if you keep it in the car all the time. If you don't have a hilariously small car, then ignore everything I just said. You may have to take it out if you're planning on hauling a metric crapload of stuff, but othewise it really shouldn't impede you. Basically, the solution to this negative is 1.) you could not keep it in your trunk (I don't suggest this one), or 2.) don't drive a roadster. If you already have a roadster, I'm sorry, but you're just gonna have to sell it. If you can't deal with the 2-seater's now barely-existent trunk, then you have to pick between this jump starter and the car. And you should pick the jump starter. Another negative thing I have is yet another thing that barely even counts as a negative. The flashlight is right above the thing you use to wrap one of the cords around. If you quickly try to wrap it up, you might get the cord caught on the flashlight just a tiny bit. Not really an issue, just something that I would change if I were to design a newer model. One negative thing that I'm seeing on some reviews of this and other jump starters is that the alligator clips break. I may have gotten lucky, or they may have gotten unlucky. Personally, I haven't had an issue with them, and I actually think they are built rather well. But it isn't worth glossing over, because if a lot of people complain about it, there may be some truth to it. Just know that even if some of them are bad, mine is proof that they are definitely not all like that. One final negative I have is the air compressor. It is an awesome thing that they included, and it could really come in handy, but it objectively is a bad thing to use for filling your tires. It is NOT supposed to be very good, after all, if you want a good air compressor, then you shouldn't be buying a battery jump starter. However, it is loud, I could hear it VERY clearly while driving, on the highway, with it in the trunk, that is a completely isolated compartment from the cabin. The first time the switch flipped after a bump, the loud noise actually freaked me out, because I heard this huge vibrating noise that would not stop, and I thought it was coming from the car. It is also pretty low-powered (again, it is attached to a car jump starter that only supplies 12 volts). It takes a long time to fill up air, and it obviously struggles getting the tire pressure up once it gets to (relatively) higher PSI. To summarize, this is an absolutely amazing device. It comes in handy in a lot of desperate situations. It can take tons of regular wear and tear as well as abuse (I would know, I'm not exactly nice to it). It manages to jump start even cars that are pretty difficult to start, and it can do it time and time again without recharging. Still, for safety's sake and just in case, I'd recommend keeping it charged. Just know that it is definitely capable of multiple jumps if 1.) you happen to need it multiple times in a row, and 2.) you don't feel like charging it every time you use it. It has some nice "extra" little features that you probably won't use a lot, but are definitely nice to have on the off chance you do need them. I keep this thing in my car literally all the time. It has not only saved my sorry butt more times than I can count, but it also allows me to use my car without worry in the winter when there's a less than 50% chance my car wouldn't normally work. If you are even THINKING about buying this, stop thinking, and give Stanley your money already. Even if you aren't thinking about it, even if you don't have a car, buy it.

Years ago I had a car with issues and my Stanley Fat Max saved me numerous times. I can't say that today's version meets me expectations. No power button, no improvements over the years, worthless flash light, zero charge, poor sticker placement and zero customer service. For as expensive as these things are, I expect better. I can't even try this one for jump starting because there's no power button. I sent an email to Stanley Support on Sunday. It's been 2 business days with zero response. (Meanwhile the packaging is just sitting out in case I need to send it back.) Amazon can't fix it without me sending it back for a complete replacement. Amazon's solution is for me to call...which I kept forgetting to do during business hours. Not convenient since I have zero time to wait on hold. I tried the number tonight and it's for a completely different company! The unit came with zero charge. It took almost 36hrs for it to fully charge. The flash light on my old one was great for seeing the tire, but I always wished I could move it around more. Not only have they not upgraded that in any way, it's so dim I doubt you could see anything with it. A couple of years ago I got a $20 pump that you could program. You'd think with all the tech advances that it something that Stanely would have. Nope. Same exact system from many years ago. Something small, but speaks to the care/quality: the sticker on the top portion wasn't placed properly. It's off and had lots of pockets of air. I tried to gently push the air out...it looks crummy and cheap. Not something that cost as much as this did. Side note: Packaging was perfect. This wasn't a shipping issue. This unit left the manufacturer this way.

Overall, love this product and have been using the compressor portion of it quite a bit. I have used it also to jump-start two vehicles, but I've mostly been using it to fill tires that keep giving low-pressure warnings. Both times I have jump-started a car, did need to let it "charge" the vehicle battery for about a minute before starting it. Other than that, worked great and both batteries were drained. Those that say the compressor hose is to short, I will agree it could be longer, but the length is fine. One of the vehicles I have used the compressor to fill a tire is a Ford Escape Hybrid with pretty large tires. When the valve stem is on top (furthest from the road) of the tire the hose reaches just fine. If you are filling a tire from empty and/or multiple tires, the hose (especially closest to the compressor) gets hot. I do like that it has a pressure gauge on it also, though you will see it fluctuate slightly. I think this is due to the type of compressor in it, and also the entire thing does shake (and can move along the ground) when using the compressor. Some have said also that it should come with it's own power cord so you can charge it from an outlet. I have multiple power cords, so this is not an issue and I think many people have power cables that will work. If this came with a power cable, it would have to be redesigned so the cable could be stored with it, and the price would also increase. If I haven't used this for about 2-3 months in the summer and have kept it in the car, the battery is still almost fully charged. All the lights are still lighting up on the test, but I know some power has been lost. I would not keep this plugged in all the time to keep it "charged", you are just wasting electricity. The battery in this is not designed for that. The only thing I haven't used on this is the 12-volt plug, so I can't say how well that works. But I'm assuming everything else works, that it does too. Now the big flaw from my perspective. The switch to turn on the compressor is easily "turned on" if something rubs against the back or if this is lying on it's back and moves around. I've been driving down the road several times when the compressor has turned on, mostly because my trunk has been empty and this thing landed on it's back and moved around, turning on the compressor. So if you do get this, make sure it stays standing if you keep it in your vehicle, or possibly put some tape over the switch when not in use. They really should have put that switch either in a different location or made it so it couldn't be turned on "easily". Pros: Easily Portable Portable Compressor Portable Jump Cons: Compressor power switch can easily be turned on by itself (by either having the unit on it's back or by something hitting/rubbing against the switch) The compressor line will get hot near the compressor if used for multiple tires or for several minutes at once.

I purchased this about a week ago. I looked at many of the reviews for other units and all of them have positives and negatives. Many of those negatives stem from DOA units which were not returnable. The small Clore unit was my first choice, i even added to the basket but switched last minute. The Clore had almost glowing reviews and seems to be great at what it offers, a small low cranking amp jumper. I had owned a Schumacher before and the thing was a beast. The brand has lower reviews on Amazon but i was 100% happy with it. In fact, in my old Volkswagen Beetle, the battery died and i ran on that little Schumacher for about a year by recharging it every night. I killed it but it served the cause like a real soldier. I would have bought another but i wanted more cranking amps than it offered for cold weather, versatility, and options. I was hoping to find something which offered a little more, such as use as a power source, but didn't want a box taking up my whole trunk (small Volkswagen hatch) at a crazy price. I decided i would spend up to $100 and get as many features as i could for the price in a brand name box. This Stanley fit the bill. I looked at the Energizer 84020 unit but by measurements on here, it sounded huge. The inverter option is nice, but giving up my precious trunk space was not an option. Stanley use to be a great brand, simple, but effective and rugged so i went for it. First impression is that it looks better than i hoped. I was expecting an ugly pseudo tough looking thing that felt generic with its over the top looks. It presents better than that. Function over form might be more important in a thing like a jump box, but if you use it at the camp sight or beach as a power source looks become a little more of a priority. Included was a needle for inflating the football or soccer ball, and a car plug which is for powering it up as you drive I guess, or trying to jump via the cigarette lighter which is a hit or miss. I wanted to test it out, so i let it charge overnight. I plugged in my android smartphone and it started charging the phone instantly. Then i grabbed my deflated football from the garage and filled it. I wanted to see how it worked on an iPhone, so i borrowed one and plugged it in. It does charge IPhone. In fact, after about 5 minutes on the Stanley you could see the bar go up by one. The next day, i jumped my dead car and it started up. Then i inflated my tires. They lost a little air the last few months while the car was sitting. Big help since you cant drive to the gas station on the flat tires, so what do you do? The inflator is loud, but did the job and didn't overheat adding 5-10 psi to all four tires. Each one took a few minutes (2-5). I think if you had a complete flat, you might be there awhile but i am sure if you pulled out the stop watch this thing would still beat AAA. The pressure gauge on the Stanley doesn't read correctly. It just always reads as low or high. Don't rely on this feature, maybe mine was a dud but i wont try to return it over that. I use a hand held pressure gauge anyway since i have never seen a built in one work anyway . So far I was happy with my purchase but had one last test to put it through. Like i mentioned, my car had been sitting. The battery was very low. I needed to buy a trickle charger but didn't want to buy yet another one time use tool. So the Stanley's final test was to be a trickle charger of sorts. I plugged the unit into the house current and ran an extension cord out to the car, clamped Stanley onto the battery and put it into jump mode. Left it to sit overnight, and by morning my car battery was full, sans trickle charger. I dont know if this is supposed to work this way but it did. It might lower the life of the unit, but for occasional use ill make the sacrifice. The work light is dim, but bright enough for a roadside emergency. Maybe equivalent to a couple candles or key chain light. Keep a real flashlight in the glove box anyway (the streamlight microstream is great one which i reviewed). A few people mentioned it doesn't have a shutoff where you can leave it plugged in indefinitely. I do know that when mine was full after charging the power button blinked to warn me. I dont want to leave this plugged in anyway. It should be in the trunk, i mean what are the chances you get a dead battery just at home? A shop might want a unit which can stay plugged in but the commuter should be less concerned about that imho. So overall, after a week of use this is a great item. The size is right (maybe about the size of a case of soda), looks tough, and can inflate tires, footballs, lovedolls etc...while jumping your car several times before recharge. It can be a backup phone charger or usb power source for the outdoorsman, and function as a makeshift trickle charger for the collector car in the garage.

I’ve had this for a couple years now. Works like a charm! Charges vehicle batteries and pumps up a slow leaking tire perfectly! Worth it!!

I drive a honda ridgeline pickup truck and my wife drive a honda civic. I've been looking for a decent jumpstarter that would be powerful enough for both of our vehicles. Rather then having 2 various models it just seemed easier to get two identical units. After reading reviews on several various jump-starters I opted for this model. Now the most negative thing I could find about this thing was it lacked a flat charger so you couldn't leave it plugged in. For me that's not even a factor, after all I bought this to charge it and then put it in the trunk of my wifes car and in the cargo area of my truck. I don't intend on leaving this plugged in. So if you plan on using this HOW IT IS DESIGNED then you too don't even need to worry about the lack of a float charger. That being said, the unit itself is a bit heavy, imagine picking up really big battery, that's essentially what this is. It has some weight to it. The jumpstarter itself also features an interesting little light that pivots as well as an air compressor. I've heard/read back reviews on the air compressor, for me it's not why I bought it. But initial checks it looks like it works fine and even has somewhere to store the air hose which is really nice. The one negative I have on this thing is the power switch for the air compressor is on the back and is not protected. In other words it could in theory be flipped on and drain the battery. So when you need to jump your car the starter would be dead. I wish they put a cover or moved the switch but honestly it would take a perfect mistake for that to get turned on so it's really not that critical. To prevent this from potentially happening I actually went down to Target and bought 2 milk crates,one for me and one for my wife. I put a jump starter, first aid kit, oil, etc in the crate so it's essentially the roadside emergency crate and also protects the jumpstarter from getting knocked around and/or turned on. Overall I spent $140 total on 2 of these and I'm really happy with the quality. They charge overnight easily, the indicator lights show you the charge remaining on the battery and it has power ports for 12volt and USB which is an added bonus. If you need a jumpstarter I would definitely consider this one.
