GOOLOO A3 Jump Starter with Air Compressor, 3000A Portable Car Battery Booster (9.0 Gas/6.5L Diesel) with 150PSI Auto-Shutoff Tire Inflator, 12V Supersafe Lithium Jump Box Car Battery Jumper Starter

Great emergency tool. I already used it twice as my car battery was coming to the end of it life. The bonus for me is the air pump. The best part is the price. It will not brake the bank; specially now days that you have to watch your money. You can buy without hesitation.

Excellent tool to keep in the vehicle. A bit loud but works well and inflates air fast.

My old Jeep Liberty (2005) has some phantom battery drain.During a cold spell (-10 C / 14 F) my car would not start.My older Loftek smaller jump starter that used to work with my older Honda CRV was totally unable to start my Jeep.A neighborhood mechanic jump started me using a Noco and a spare battery.My alternator was fine, and my Jeep's battery is a Duralast that I purchased a month earlier.I bought a Noco "Used Like New" but it was defective, and another random brand here on Amazon, which had no boost/override button. so I sent them back.The Noco's downside was that it still uses Micro USB and it charges slowly.After going through a rabbit hole I decided to take a chance with the Gooloo. I was worried that the model with the air compressor/tire inflator would not be as good as just their dedicated models.But this worked flawlessly on some more freezing days. The first time I had to press the "boost" button on the cables to start the car. A few days later when it was warmer it just started it right away.I tried the compressor / tire inflator on my front tire that has a slow leak. It went from 26 to 33 PSI in about 90 seconds and the indicator was still showing full charge.So this is a great buy.I have a AAA membership, but you get only 4 roadside assistance services for free per year. I would rather call the AAA assistance only when there is some serious breakdown. Also often you have to wait an hour or more for service.This jump starter/ tire inflator is cheaper than calling the AAA after you used up all your 4 service calls, or better than hoping someone will stop and jump you with cables.I have a separate dedicated tire inflator compressor that is powered by the cigarette lighter plug. I would rather use that and keep the Gooloo for emergencies or as a backup.It is great! totally recommended. I store it in a fire proof LiPo bag, as I am not sure if this is Lithium or LiPo, but in any case it seems very powerful.Totally worth the money.

Perfect unit. I've used a few different ones before. The nicad systems don't hold a charge and are large and heavy. I've tried cheap lithium ones that won't take a charge. The only battery pump I used started smoking before it finished the first tire. This is the first jump starter I've used that I liked. I also needed a air pump so my getting the value of both. There is also a light. It pumps very fast and it stops when it hits the desired pressure. Comes in a case with attachments.

This charger, tire pump works as advertised. You preset the pressure you need, hook it up to the tire and it quits when the tire is pumped up. Yesterday we pumped up 5 very low tires and the battery still had some juice left. It takes a few minutes to pump up a tire, but you can walk away and come back when its done. It is loud, that's another good reason to walk away. In an effort to avoid damage to my car's computer, I quit giving others a jump from my car's battery. This thing is easier anyway since you don't have to pull your car around the front of theirs and all that . Simply hook this thing to their battery or charging station on lots of newer cars and it gives them the jump they need. I keep this thing charged up and carry it in my car in case I need a jump and no one is available to help. This is a handy safety device. I really like the fact that you don't have to plug in this air pump, the battery does a good job.

Bought 1 as a Christmas gift. I ended up buying 2 more, 1 for my oldest son & 1 for my hubby. They seen it & loved all the features on it. They were on sale & it was almost 1/2 off. They work great & do multiple things.

I have a rolling air compressor that is a chore to roll out, pump up, and then find the correct attachment for. I tried this one out and it was an immediate improvement. I can just keep it in the car and connect it to the tires when the temperature changes, to correct my tire pressure.It's hard to describe the relative convenience difference between dragging the tank out and holding the connector just right so the air doesn't leak, versus locking this onto the valve stem and hitting the start button. It reads out the tire pressure on the display, and turns off when it hits my set point. A check with a mechanical gauge shows that it's pretty accurate.I also have the jumpstarter-only version of this and it is a pure pleasure to use compared with jumper cables, portable chargers, and all that. With a 4cyl engine without a battery in it, it cranks the engine faster than a brand new battery. I've started my riding mower many times with it, and my 4L 6cyl engine cranks like summer in the dead of winter with the chunky lithium batteries these have. It also helps to use a room-temp battery when your car's battery is too cold, so that's part of the advantage.One thing that makes me worry about the air pump is that the hose does tend to warm up after 2 tires, and letting it pump to atmosphere doesn't seem to cool it off. I don't know how much heat is too much for this device, and so I do let it take a rest for a minute or two for each car tire after the first two. It does have a much heavier hose than a lot of portable pumps, but my experience with those has me worried about letting it get very warm if I don't have to.

Nice quality, simple and works great!!!
