So far no issues, had it over a month and it’s great.Jump started my friends car and it turned on effectively. It jumped started a v6 truck. The battery was barely impacted. I’ve used it 3x on my tires when they’re low on air. It has also been useful hence one of the times I pump air it was due to a nail puncturing my tire and I inflated it enough to get to a tire shop. It’s easy, compact, and straight forward to point it’s very safe to use.

The media could not be loaded. I ordered the GOOLOO A3 specifically because it claims to have enough juice to fire up a big V8. I haven’t had to test that feature yet — and hopefully never will — but knowing it’s capable is exactly the peace of mind I wanted in my trunk.So far, I’ve only used it once to fully inflate a low tire on my car. It did the job without any trouble. I was happy that it arrived at 80% charge right out of the box, so I didn’t have to wait before putting it to use. After inflating the tire, it’s still at 76%, which tells me it holds a charge well.It’s compact enough to fit in a glove compartment, but I keep it in the trunk so I have space up front for all the usual required paperwork and other odds and ends. Between its size, power rating, and the built-in air compressor, it’s a tool I’m glad to have for roadside emergencies.Pros: Claimed power to start a big V8, Arrived pre-charged at 80%, Fully inflated a tire with minimal battery loss, Compact size for glovebox or trunk storageCons: Haven’t tested jump start feature yet (hopefully won’t need to)

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.

I bought these for our work trucks and today my own car had a check tire pressure light come up. Excellent opportunity to try out the air compressor feature. I selected car, hooked up the cable from the tire to the unit, selected the correct PSI and hit the start button. I liked the read-out screen to tell me my tire pressure and then watched it fill to the correct amount and automatically stop when reached. Filled all four tires back up and no more check tire pressure light. Super happy with the purchase.

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.

The convenience of jumping your car or adding air to your tire is small, great design, and easy to use. It jumps a V8 Yukon with no problem.

Used it for jump starts and tire inflation in the first month after purchase.2 jump starts on a truck with a weak battery. Worked perfectly.Topped off tires on car and reinflated flat tires on bicycles. Stopped exactly on the preset pressure as designed.The only negative so far is the short jumper cables that come with the jumpstarter. It is a bit difficult to position correctly on large batteries to get the green light.
