I have used this for both filling my tire and jump starting a car. As long as you have the unit charged up it lasts surprisingly longer than expected. I filled up all four of my tires from a 24 psi to 34 PSI. And there was still a bar left on the charge. It is extremely easy to use. Absolutely worth every penny. This is the second item I've bought of this brand and I couldn't be more pleased.

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.

Does the job. My suv battery has been completely dead for over a month so I need this product to get it going. I ordered two other jump starters before I found this one. Even though the other two had higher amps, they did absolutely nothing when attached to the battery, so they were returned. I hooked this Gooloo up and the suv started immediately. This one’s a winner.

Does exactly what it needs - got my car started. Compact formfactor that's easy to store. The biggest issue I have is all the buttons being together, and CONSTANTLY pressing the damn air compressor button, which starts up immediately and it's LOUD. How hard was it to put the switch for the LOUD AIR COMPRESSOR off to the side or something? 5 stars for performance, -1 for terrible interface design.

I bought this because I misplaced my other one. Having a compressor and jump pack all-in-one has saved me (and friends) many times. I charged this up and was able to test it right away. My car had been sitting for a couple of weeks and had a dead battery and a flat tire. I first jumped the car, and it started right up. I then inflated a fully flat tire to 32 PSI. Worked like a champ! It also serves as a power bank for cell phones and the such. If you don't already have one of these, I highly recommend them for emergencies! They pay for themselves after one use.

My husband is excited to have this in his car. In the winter when your tires deflate you don’t have to drive around and look for an air pump. You can use it in the convenience of your own garage. It’s capable of filling all four of your tires on a charge and still have battery life left. It’s worth the peace of mind of having it in your car available for a jump if necessary.

Its like having AAA in your glove box. Air compressor, battery booster, work light And I can charge my phone or tablet too. Great Buy Very Happy!!!!

It said it good for 6L diesel, so I bought it to start up my old Tundra. It works great in the first time, but went dead in the 2nd time . The air compressor is fine. Fast and easy to use.
