Car Jump Starter - 900A Peak Jump Starter(Up to 6.0L Gas/4.0L Diesel Engines), 12V Auto Battery Booster/Tire Inflator, Power Station with DC/USB Ports - Black

Was pleased to see that the battery was still FULL after jumping the car twice. Worked great.   Easy to charge, super easy to use the car jumper cables.   The cables are somewhat short BUT the unit is so light and small that you can set it anywhere without worry.   I have had no need to use the air station yes but expect the best.   I am still impressed with this item - I could have spent 3 times as much and am so glad I gave it a shot. The instructions are pretty clear, and the product is fairly easy to use as well.

My 5. 7L Hemi Challenger had sat in the garage all winter and the battery was pretty weak.   Weak enough it would not even turn over the starter in the car.   I hooked this up and the Challenger fired right up. I finally had a cause to use this in the real world.   The battery indicator on the jump starter was still at 75% afterwards, so you could do a few jumps if you had to between charges.   Very satisfied with its performance. 3 diesel ambulance camper that I had sitting w no problem.

Works like a charm. First thought was how can this small box jump start a dead vehicle battery with no issues. . but it did! Great purchase! Great product!.

This charger is very compact and easy to use. My husband and I have used this twice now to jump our cars.  My daughter takes on her commute to college for a back battery for her phone and laptop.  I even encouraged my brother to get one definitely worth the purchase!!.

I do not know what happened to my previous review.  But here it is again. This works great.  I had a pickup with a short battery that was completely dead.  Hooked this up and used the boost button.  I now keep the charger in the trunk just in case.

Get it use it.  Paid itself off super quickly.   Also we recently purchased a lighter.  This unit is heavy when you pick it up , but it is worth it is weight ! It will start a dead vehicle and after it is running it quickly let us you know that the vehicles charging system is working or not. We are a very busy Auto Repair shop and we cannot do without this thing.

I wanted to see how it worked on an iPhone, so i borrowed one and plugged it in. I purchased this about a week ago.  It does charge IPhone.  In fact, after about 5 minutes on the Stanley you could see the bar go up by one.  The small Clore unit was my first choice, i even added to the basket but switched last minute. The next day, i jumped my dead car and it started up.  I had owned a Schumacher before and the thing was a beast.  Then i inflated my tires.  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.  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 did not overheat adding 5-10 psi to all four tires. I was hoping to find something which offered a little more, such as use as a power source, but did not want a box taking up my whole trunk  small Volkswagen hatch  at a crazy price.  Each one took a few minutes  2-5 .  This Stanley fit the bill.  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 does not read correctly.  Stanley use to be a great brand, simple, but effective and rugged so i went for it.  Do not rely on this feature, maybe mine was a dud but i wont try to return it over that.  I was expecting an ugly pseudo tough looking thing that felt generic with its over the top looks.  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.  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.  Like i mentioned, my car had been sitting.  I plugged in my android smartphone and it started charging the phone instantly.  The battery was very low.  I looked at many of the reviews for other units and all of them have positives and negatives.  I needed to buy a trickle charger but did not want to buy yet another one time use tool.  So the Stanley's final test was to be a trickle charger of sorts.  The brand has lower reviews on  but i was 100% happy with it.  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.  I would have bought another but i wanted more cranking amps than it offered for cold weather, versatility, and options.  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.  The inverter option is nice, but giving up my precious trunk space was not an option.  It might lower the life of the unit, but for occasional use ill make the sacrifice.  It presents better than that. The work light is dim, but bright enough for a roadside emergency.  Maybe equivalent to a couple candles or key chain light.  Then i grabbed my deflated football from the garage and filled it.  Keep a real flashlight in the glove box anyway  the streamlight microstream is great one which i reviewed .  The Clore had almost glowing reviews and seems to be great at what it offers, a small low cranking amp jumper. A few people mentioned it does not have a shutoff where you can leave it plugged in indefinitely.  I decided i would spend up to $100 and get as many features as i could for the price in a brand name box.  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.  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.  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.  Many of those negatives stem from DOA units which were not returnable. 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. First impression is that it looks better than i hoped. .  I killed it but it served the cause like a real soldier. 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 looked at the Energizer 84020 unit but by measurements on here, it sounded huge. . I wanted to test it out, so i let it charge overnight. Had to use this a couple times in the several months since I bought one, and it works just as advertised.

I have tested this on my 2016 toyota camry and it worked smooth, build quality is good and looks very durable.  Tire ran out of air it has a pump also.

I only had to use it once, The next day, I let a friend use it on an old car he had in need of a jump and it worked again with no problems.   So far I am giving 5 stars.   It had a newish battery that I had put in less than a year ago.  Will update if another couple weeks go by without the gift promised after registering warranty.   I got a jump from my landlord and made a quick trip thinking the battery was fully charged. I like that it is light and compact and fits in the small glove compartment.   Rather than begging people for a jump I searched  for some kind of jump gizmo that would start a 99 Chevy Prism.   I have not used it to charge my Phones and Kindle, etc.   One cold morning the battery was just dead.  yet. I like that it took only a couple seconds to crank my car up.   No dislikes so far.   The next morning it was dead again. When it arrived, the battery was charged to 75%.

Will probably replace it with another brand. Very disappointed. Follow up! Above  was read and understood by a real human.  Finally even the led light stopped working.  These folks at Hulkman responded to my concerns and made it okay. Of course it was too late to return it.  I have purchased a new Hulkman.  It is now an attractive very expensive brick. Thank you.  Started a couple of low batteries just fine. Worked right out of the box, booster worked well.
