GOOLOO A3 Jump Starter with Air Compressor, 3000A Portable Car Battery Booster (9.0 Gas/6.5L Diesel) with 150PSI Auto-Shutoff Tire Inflator, 12V Supersafe Lithium Jump Box Car Battery Jumper Starter

Amazing jump starter. It holds a charge for a long time, is highly compact and easy to store, and works quickly and efficiently. I’ve owned many jump starters that were slow and lost charge fast, but not this one. An amazing choice!

A must have in all vehicles for emergencies. This unit is fairly small in size but packs a big punch. It has no issues starting my 5.7 liter V8 with a dead battery. The tire pump feature is also a nice touch but I recommend only using it to top of the tires, not fill from completely flat. The jump start and pump feature are both very easy to use. It weighs little enough and small enough to store in the vehicle full time. I've owned it for 2 months now and the battery is still on full bars without charging.

These things are AMAZING!!!! We had a small portable charger that you could use to jump-start a car, but after a number of years the battery was dying. So we researched whether we wanted to get the same one or something different, and we settled on this. This is SO MUCH better! This can jump-start your car or provide portable power for things, but it also has an air compressor. Just like the ones at the gas station, you can set the level of PSI you need for your tires and then it will inflate to that level. It's so small and compact it's easy to keep in the car without taking up much room.

Got this for christmas and has already come in handy. Aired up 2 bikes and my car with the air compressor. Love the long battery life, the psi reader and the price was amazing. I did get this during black friday so not sure if it was on sale or not. But it does exactly as advertised. Small design and the instructions were super easy to follow.

Working great so far. Not difficult to use , I use it for air compressor feature. But also comes with battery jumper cables. Nice compact size.

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.

Update... Was going in to a store & a guy had jumper cables running to another car & was trying to get jumped off.. I heard him try to start his car and it was nothing but click click click. I decided it's the holidays I'll try and help out so I went to my car and got out my jump box .. I walked over and said can I help and he said sure my battery is completely dead and will not jump off , I said no problem I got something that'll fix that .. I connected my box he got in his car, cranked right up.. This is a great item to have in your car & a necessary tool that will save you from freezing, waiting on a tow or hoping you can get a jump from a stranger.. A new car, running could not start his car w/jumper cables, but my little jump box, first try & he was ready to head out.. I love this item.. The jump box came with a lot of parts & pieces.. Multiple ends for the inflator so you can inflate most things you could need an inflate for, including a flat tire.. The display is easy to read & simple to understand.. The inflator is a bit loud but at least you know it's on, but if you didn't the lcd screen will let you know.. You can choose between multiple air units incl psi, kpa, etc.. Also you can program the air level you want it to stop at when inflated.. This thing has a tons of features for a Jump Box that costs less than $100 like a lot of comparable models.. As far as the car jump box side, it has a regular charger to charge your battery or there's a BOOST button so you don't have to wait for the battery to fully charge.. If you use the boost button, the car will start right up like a jump from another battery, only better..

This thing is absolutely amazing!!! I've filled multiple car tires and helped jump someone's car. It works just as advertised. I would and have recommended it to others!
