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.

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.

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..

I've been using this to top off my tires for several months now and it has performed as expected. Today I had a flat tire on my Wrangler. Stock tires, not big ones but still bigger than a typical car tire. I was aiming 36 PSI. The inflator took it from 0 PSI to 32 PSI in about 15 minutes with the battery depleting about 75%. It wouldn't go higher than 32PSI but I think the inflator was getting hot and needed to cool off for a bit. Either way, 32 PSI was plenty of air pressure to drive on and I topped it off with an air compressor for the last few lbs. I have not had to use the jump starter yet so no comment on that but as a tire inflator I think it works well. Of course it is noisy and slow but that's how these compact devices are. Good purchase.

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.

Inflates MANY tires per charge. Have not used the jumper yet, but like the fact the battery is charged and ready for work at all times. Accurately inflates to set pressure!

So far, I am pleasantly surprised with the GOOLOO A3 Jump Starter. I haven’t tried to jump start a car yet, but I did use the air pump to inflate car tires. I am replacing an old portable lead battery jumper, and a plug in the dash accessory socket-air compressor. The air pressure setting is accurate; I checked it with a good tire gauge. It inflated the tires and shut off much faster than the old plug-in compressor. One suggestion for improvement would be to mark the buttons’ and include functions so they are more visible and easier to navigate in low or no light situations.
