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

This GOOLOO A3 jump starter is super handy to have in the car. It started my vehicle quickly with no issues, and it’s really easy to use. The built-in air compressor is a big plus. It fills tires fast, and I like that you can set the pressure and it shuts off automatically. It’s compact, holds a charge well, and feels solid. Definitely a great all-in-one emergency tool. Highly recommend!

My husband says this is the best gift he has ever received! I know he's exaggerating, but he has used to start an old Bronco, his old F250 Diesel, the lawnmower and the tractor. SO MUCH EASIER than dragging jumper cables out to the pasture or anywhere. It also has a tire inflator that we have used several times on the old trucks. Takes it a while to fill up a big tire but it works. Highly recommend as a very handy tool to keep in the garage or in the car. It works quick to start a vehicle. It won't charge a battery, but it will jump one off and get you running.

My Mazda CX-30 wouldn't start one day. I knew these rechargeable jump starters were a thing so I jumped on Amazon and got this one same day. Worked like a charm! Inside the main unit is basically a giant power bank. It charges with a USB-C in, which is awesome and universally available. It even has a USB-A out port to charge another device. I charged it up to full when I first got it, even though it already had some juice in it and I *think* you'd be able to get an emergency jump right out of the box if you needed to. The directions are simple. Plug the battery clamps into the box, then clamp them onto your battery. A green light tells you that it's ready to go. Press the BOOST button, then go into your car and start it up with in 30 seconds. Then remove the clamps and away you go. No sparks, no scary sounds, no worries. I jumped it twice and it still had enough charge for possibly a few more. Other great emergency features: the tire inflator has programmable pressure. The light is nice and bright and stays steady for a flashlight or blinks for emergency. And I already mentioned the USB out for charging another device. This is a great, indispensable emergency device for anyone's car. I'm glad I got it and I'll make sure it stays charged in my glove box.

GOOLOO A3 Jump Starter with Air Compressor, 3000A Portable Car Battery Booster Peace of mind. Easy. Fast tire inflation. Quick, fail proof, battery charger. After hitting the booster button located on the jumper cables attachment, I got back in the car. It started without hesitation. Works like a charm within moments. And, after charging the car battery, the 3000A power indicator showed 75% power remaining. That's when starting at 100% fully charged jumper. And, after inflating 4 tire, the 3000A power indicator showed 75% power remaining. That's also when starting at 100% fully charged device. Great investment for safety and convenience.

This has been a pretty helpful thing to have in the car. My tires have been losing pressure recently and this helps keep them topped off while I wait to change my tires. It's easy to use and the value for the price is great. The main issue is that it seems to need a full charge in order to jump a car because I had issues using it to jump my car when half charge, but no issues at full. Also the cable lengths are a bit short.
