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

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.

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.

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.

The Gooloo A3 arrived and it was charged over night. It came with a 75% charge out of the box. I needed to inflate a fat tire bike that required 25 PSI. The lowest bike tire setting was 30 PSI. Ended up setting it to the car setting and was able to get a 25PSI setting. Attached the nozzle to the tire stem and air started leaking from inside the device. Pushed start and nothing, it just turned off. Found you have to press the power button one time quickly to start compressor. Once it started it filled the tire and when it shut off there was no longer a hissing from inside the device but the actual pressure was 36 psig. The tire max pressure was 30 PSI. Okay...it works. But don't trust this to shut off at the desired pressure. Luckily it didn't rupture the tire. The instruction book is beyond basic and pretty useless. The case is nice and the compressor attachments will be good for filling an air mattress while camping or foot/basket/soccer balls. Just remember to adjust the pressures manually. As for the jump starting, Haven't needed it yet. Replaced a dead battery yesterday. That's why I got this today. But from the you tube reviews it seems to work well for that purpose. The manufacturers video says it will hold a charge for two years. There is no mention of that on the packaging or in the "instructions". So who knows. I'd say check it at least a couple of times a year and charge as needed.

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!
