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

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.

This thing is great! It does take a while to fill a tire but when your in a pinch this is such a great backup option. It's lightweight and compact and has a great battery life. I got this for my son to have in his car at college and he's had to use it multiple time in his old car. We're so glad we got it for him and he is too! Good price too!

This is the greatest device ever and so easy to use. We keep it in the back of our car and can easily assist someone else with a dead battery. Price is very reasonable and besides, its peace of mind, knowing you have it. Made of quality material and seems to work very quickly and easy to hook-up to jump your battery. Definitely would recommend to family and friends.

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.

Amazing that so much power can be stored in such a compact device. Started cars and trucks with dead cells in batteries about 6 times before I plugged in to recharge. Air compressor is easy to use and faster than other similar devices I have owned.

I highly recommend. I have been stranded with dead battery and had to wait for someone to come jump me off. Never again! It’s so easy to use and only takes a few minutes to get you back in the road.

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.

This device has been awesome. Used multiple times-It has paid for itself!
