Compact, Powerful, and a Total Time Saver
This has quickly become one of those tools I didn’t realize I needed until I had it. It’s small enough to keep in my trunk without taking up much space, but it packs a lot of power. The air compressor alone makes this worth it for me. I have a tire with a slow leak from a patch, and this let me put about 4 lbs of air into my tire in under a minute. That is huge. No more dragging out a full-size air compressor, plugging it in, waiting forever for it to build pressure, then overfilling and having to let air out before putting everything away again. This is fast, simple, and convenient. The jump starter works just as effortlessly. I really appreciate the built-in safety indicators. The red light clearly tells you something isn’t hooked up correctly so you don’t continue, and the green light gives you confidence that you’re good to go. That takes a lot of the guesswork and stress out of the process. The boost feature is also a great bonus if you ever need a little extra help. Overall, this feels like a solid, well-made unit that delivers excellent value for the price. It’s convenient, powerful, and gives real peace of mind to have in the car. I’m very glad I bought it.

Highly recommend this company!! & their products!
Product is great! It can jump start a dead battery with ease & fill tires up with air in no time! Its very compact & easy to carry around with the travel bag. Very simple to use & enough battery power to keep in the car for weeks! Fiona from Gooloo was also very helpful with an issue I came across & offered great options to resolving my issue. 10/10 customer service!

Great Autor Accessory for Peach of Mind
Had the unit only a couple of days when I had to use it to inflate a low tire. Worked very well. Amazed at the power of the battery to pump up the tire so quickly. The unit is well constructed and easy to use. Battery holds a charge for several months so you don't have to constantly worry about keeping it charged. The unit came with a defect in the battery booster component. I shared this with the company and we tried several approaches to trouble shoot the problem. Wasn't able to fix the problem so the company provided me with a new unit that works. Their communication and customer support is outstanding. I highly recommend this unit as a back up for peace of mind for either tire inflation or battery jumping.

Great little jump starter.
This is a very nice little safety net for your vehicle. My daughter recently turned 16 and started driving on her own. Her uncle gave her one of these as a birthday present. We charged it and showed her how to use it. During a recent cold snap, her battery failed before school. I showed her how to use it and it worked great. After school, her battery wouldn't start the vehicle. She was able to hook it up and start her vehicle all by herself. In total, it was used three times and only used one bar of power. I was very impressed with the simple design and function of this device. I ordered another one for my wife and hope to purchase a couple more as budget allows for our other vehicles.

Great, but not for snow blower tires.
Does not offer a setting of 20 PSI for my snow blower tires. It is easy to use, the display is easy to see, it automatically stops at the set PSI, it inflated 4 car tires and bike tires without issue. I am pleasantly surprised at the battery life. I removed 1 star because it does not offer a setting of 20 PSI for my snow blower tires. I looked through all the available modes on the display; vehicles, bike, and basketball. Each mode has a specific low PSI range up to a specific hi PSI range, none of the modes offered 20 psi within their range. Othewise has been great inflator and I would buy it again, just not for the type of tires found on some snowblowers.

Convenient, high powered car assistance
Bought this after reading other reviews. It has not disappointed. As mentioned by others, it holds its charge well. There were some complaints of the compressor not working quickly enough. I have found this one to actually be much quicker than a name brand pump I plug into my car's 12 volt outlet. For example, it only took 90 seconds to inflate a small sedan tire from 21 to 32 psi. My other pump would have taken 3-4 minutes, plus I would have had to plug it in. As advertised, it will tell you the current tire pressure and allow you to set the target pressure, then automatically stops when that pressure is reached, allowing you to work on something else in the meantime. It also allows you to indicate what type of tire you are pumping up, bike, car, or truck/SUV. The safety light feature is also very nice. It provides a steady light or two different speeds of flashing. The device and the attachments fit easily into the sturdy, compact nylon case. There's no need to shove stuff in. I will be buying more.

Works Great & easy to use
Works Great! I had to use it the week after I purchased it. I have a tire that loses air when our temperatures (W. Michigan) drop below freezing, which has been frequently this year. This saves a trip to the gas station where sometimes the air hose nozzle can be frozen and not work. After reading directions, it took very little time to re-inflate my tire. I feel confident, (70 yo) winter driving, having this handy, easy to use GOOLOO Jump Starter & Air Compressor in my car. It comes with different air nozzle tips to inflate various items. It also has a multi use light for emergencies. It has USB rechargeable cord to recharge. You choose preset air pressure amount, then it automatically shuts off after it fully inflates item. Hoping I won't have the need, but I am sure battery charger will work great as well.
