Cordless Tire Inflator Portable Air Compressor-4000A Jump Starter with Air Compressor, 150PSI Portable Tire Inflator for Car, 12V Car Tire Air Pump with Tire Pressure Gauge, 8000 mAh Power Bank,Lights

This is a great little air compressor! I used it to fill up my bike tires several times, and it gets it done in no time. The jump start does work well on smaller cars, but it doesnt do much for trucks or SUVs. With that in mind, it is a great multi tool for a smaller sedan or subcompact SUV and maybe some wagons! It's not too heavy, so I've been carrying it on my bike or car, just whatever I'm using that day, and I've only had to recharge it a couple times. Great little product overall!

Item received 10 days after order. This is a portable car jump starter and air compressor.The label on the box calls it an “air compressor” with no mention of being a car jump starter. It comes with the main unit and cables to charge it, jump start a car, and inflate tires and other inflatable things. It also comes with a velvety draw-string storage bag.The instructions are inadequate. For jump starting it says to “plug the EC5 plug into . . .” with no description of what that plug is. There are a couple of picture descriptions of the parts, but no EC5 plug. Also limited written instructions of how to jump a car. If you have jumped a car before you can figure it out, but if you never have these instructions are not adequate. There is a short pictorial and video on the Amazon product page, but the pictorial should be included in the instruction sheet. If I am stuck someplace with a dead battery, I want clear instructions in my hand. There is a digital display on the unit. Again, the instructions do not even mention the display and give no clue as to what the various displays mean.After fully charging, I had a dead battery about a month later. This unit jump-started the car readily. I have not tried the air compressor function. I see that another reviewer gave a very detailed review about that.

This works great for my car. It saves a lot of room because I no longer have to carry around a large set of jumper cables and a tire inflator. Now I have a two-in-one. I do have to wait a few minutes before trying to start the car or else it may not start up. Having a tire inflator comes in handy more often, of course, just to top off my tires if I’m away from home. Definitely a good item to have for emergencies.

This is a great tool to have in your trunk. It sucks getting stuck somewhere with a dead battery, and most people don't drive around with jumper cables these days, so having the ability to jump your own battery is great. Being able to top up your tires on the go or being able to inflate your backup tire in the case of a blowout is also very nice. The display is bright and easy to read, the pump works well but does take some time to fill your tires if you are doing all 4. I still use my air compressor when at home. Instructions are clear.One downside is that it is battery operated and doesn't come with an adapter to charge via a cigarette lighter. I know a lot of new cars have USB ports built in these days, but I have an older car, so the inclusion of and adapter would have been nice. Also, you will need to check the battery on it every so often to make sure it is charged. If your battery dies and this tool is dead, it isn't going do you any good. It also needs to be close to fully charged to be able to jump start a car, so if you chuck it in your trunk and forget about it, odds are it may not be useable when you need it.

We have an older vehicle that occasionally needs a jumpstart and used to have to jump it from another car, this jump starter alleviates that hassle. All you need to do is plug it into a standard electrical outlet and charge the unit with its included USB-C cord. After it is charged plug the included jumper cables to the unit then to your car battery, red going to positive battery terminal and black to the negative terminal or ground, then start your car and remove the cables. What I like about this particular jump starter is its simplification, I've tried others that you have to depress a button first that has a countdown, and you have to wait for it to finish needing two people one to watch the jump starter while the other starts the car. This also has a flashlight, roadside SOS and you can charge your cell phone from the unit. This is an added insurance to have in your car should you need any or all of its safety features. while on the road
