Good thing to keep in your trunk
Color: Red
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.

Worked like a charm to jump start my Mazda
Color: Red
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.

Great for emergencies !!
Color: Red
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!

Great little tool
Color: Red
Does at it should. It's a little loud when using it on a car tire. Was unable to jump start a dead car. Battery life is fairly decent. Good for emergencies

Got a nail in my tire and this kit made the repair so easy. Everything you need is included and the instructions were straightforward — no mechanic needed. Worked perfectly and held up great. Highly recommend keeping one of these in your car!
