GOOLOO A3 12V 3000A Portable Jump Starter with Air Compressor

Overall, the GooLoo A3 has been a very good purchase, & I'm very pleased with it. I've used it to jump start 2 cars, & it worked great in both cases. Just turn it on, connect clamps to terminals, & the car starts. I used it to inflate my tires, & was surprised at its speed. Two tires were around 27 psi & two were around 31 psi. They were all at 33 psi when I finished in less than 10 minutes. The GooLoo displays the set pressure, current tire pressure, & shuts off automatically. That was great & a hell-of-a lot better than driving to some pay-for-air spot that costs 4-5 bucks & then doesn't work. If there are any negatives, it would be the length of the USB C cable. It's about 9-12 inches but can be used in a pinch. I just use a longer cable. It takes some time to charge the GooLoo. It took about 2 hours when I first got it. It takes about an hour after it's been used to to jump start or inflate tires. It's not a big deal, it stays charged no problem. But don't be under the impression that if it isn't charged then you can charge it in 5 mins & go jump start a car. Just keep it charged.

Decided to finally get this after getting a nail in my tire and getting help from a good samaritan. Excellent product that's easy to use. So far I've only needed to use the air compressor portion but that works great. Will update whenever I have a chance to use the jumper portion but no doubts this will work well. Battery seems to have plenty of charge and works fine for ~10 tire re-inflates on one battery. Air compressor is a bit loud but otherwise works great.

Bought this to replace one of the larger defective jump packs at my shop and boy it does not disappoint. Pros: I’m not sure how many volts/amps this thing puts out but it’s a lot. Our other larger jump pack struggles starting cars with completely dead batteries. It will start them but they turn over far more slowly than with a good battery that’s just low. Hook this thing up to a car with a dead flat battery and so far without fail it will turn the car over faster and harder than the car would do with a brand new fully charged battery on board. Only with diesel trucks does it sound like it’s putting out equal the power the stock batteries do. The pack has enough juice to air up 4 flat 215-45-r17 tires (car was in the back lot for a few years) and still have enough to do a jump or two. Tire inflator is a lot faster than all of the units of this type that I have tried including ones that plug into the 12v. However it’s FAR slower than the Milwaukee M18 unit we have at the shop. Though in fairness that unit is 3-4 times the size and price of this one. Cons: Takes far longer to charge this unit than the USB C charge port leads you to believe. I have tried chargers from 5-65w and if completely drained it takes 3-4 hours to charge it regardless of the power output capability of the charger you are using. Also if you are trying to jump a car that will not start for other reasons than a dead battery you only have about 3-4 solid 15-20 second cranks in it before it’s drained. Also the pack shuts itself off after a cranking attempt has been made. In the case that the car doesn’t start on the first attempt you have to get out of the car and press the button to turn the unit back on again which is mildly annoying. Finally the user interface is not very intuitive but its not impossible to get the hang of. Overall this has been a very solid unit regardless of price. For the money it’s an outstanding buy. It can easily start 10+ cars in a row if the only reason they won’t start is a dead battery. I even bought a second one to keep in the wife’s car for emergencies.

I've been using the GOOLOO A3 12V 3000A Portable Jump Starter with Air Compressor for several months, and it has proven its value more than once. In fact, I was so impressed with its features and reliability that I purchased one for each of our family vehicles. Having one readily available in every car provides a level of peace of mind that's hard to put a price on. The jump-starting capability is what initially attracted me to this unit, and it has delivered every time we've needed it. My family has used these jump starters multiple times to bring vehicles with dead batteries back to life without another car or waiting for roadside assistance. The process is straightforward, and the unit provides enough power to start a vehicle with confidence when you're stranded. The built-in air compressor has also been incredibly useful. We've used it to inflate low or flat tires when getting to a gas station wasn't convenient. Having both functions combined into a single device makes it much more practical than carrying separate emergency tools. In real-world use, the unit feels well-built, easy to operate, and compact enough to store in a vehicle without taking up excessive space. The display is easy to read, and the overall design is intuitive, even for family members who aren't particularly mechanically inclined. Pros: Powerful and reliable jump-starting capability Built-in air compressor is extremely convenient Eliminates the need to wait for roadside assistance in many situations Compact enough to keep in the vehicle Easy to use and understand Excellent emergency preparedness tool Cons: Larger and heavier than a basic jump starter due to the integrated air compressor Requires occasional charging and maintenance to ensure it's ready when needed Overall, this has been one of the most useful automotive purchases I've made. Between jump-starting dead batteries and inflating tires, these units have saved my family from multiple stressful situations. I rarely write reviews, but this product has genuinely earned its place in every vehicle we own. If you're looking for a dependable emergency tool that does more than just jump-start a car, the GOOLOO A3 is an excellent investment.

Small and works great. I charged it once around the holidays and stayed charged all year. Great tool to carry in the car. I've used it myself and borrowed it to others on the road. Highly recommended 👌.
