AstroAI S8 Car Battery Jump Starter, 1500A Peak Car Jumper Starter Battery Pack for Up to 6.0L Gas & 3.0L Diesel Engines, 12V Portable Jump Box with 3 Modes Flashlight and Jumper Cable (Orange)

This thing is awesome! I bought it when our car’s battery started dying because I didn’t want my wife to get stranded. Everyone who saw it laughed at how small it was and said there was no way it’d start our van. Well as luck would have it, the battery died at our relative’s house and they all came out to watch as I used it and it immediately got our van started. To test it further they asked me to start their side-by-side vehicle and it worked the first time there too. They immediately ordered one of these themselves. It’s so convenient. It’s a small box and the bag it comes with fits it, the cables, and a charging wire. It’s also easy to use. Red to red, black to black, hit the boost button and turn the car on. It’s literally one of my favorite things to keep in the car now. I have so much confidence even after our battery has been replaced that I will never have to fear that happening again.

I'm ecstatic about this product! I've been using this jump starter for many months now, primarily as a power bank when I go on trips. However, I finally faced a situation where my car's battery was dead, and it was so dead that it wouldn't even hold a charge (my car hadn't been started in over 3 months, so the battery was toast). So, I plugged the AstroAI car starter cable into the car starter device, then connected the clamps to my battery. Since my car battery was so dead, and had such low voltage, the little green light was flashing (instead of solid green). So, per the instructions, I pressed the 'boost' button, and the light immediately went from flashing to solid. Once it was solid, I got into my car, and it started right up on the first try! This 'AstroAI S8' car battery jump starter is the real-deal - it works as advertised, and it was a lifesaver for me that day. I didn't have to call anyone for a jump start. Normally I would've had to call AAA, or a friend - but not anymore.I highly recommend this product to anyone who would be highly inconvenienced to find their car battery dead one day. It happens to everyone at some point, especially when your car battery is nearing the end of it's service life. A dead battery is usually the first sign that you need to get a new battery.

Giving this product 5 stars because of the great customer service. I ordered one of these a year ago. It originally worked fine. Initially charged up fine and worked. Was stored over the winter (heated indoors) and when I pulled it out this spring the batter was completely dead and would not accept a new charge at all. I left charging for over 36 hours and it was dead as a door knob. I contacted AstroAI customer service as there is a 2 year warranty and they replaced the unit immediately. I had one shipped and delivered from Amazon within a week of my original complaint.

Works Fantastic. I bought this as a anniversary gift for my husband. We went to work, and someone's car battery had died in the parking lot. So he took the opportunity to use this. Started the car right away. It is light weight, comes with a carrying bag. Does not take up much room. And you can get peace of mind, if your battery does die, and you need a boost, this makes it so much easier, because you don't need a second car, or carry around long jumper cables.

The only reason why I’m not gonna give five stars is because I charged it for one full day and as soon as I used it to turn on my car, it went down to 75% battery. Other than that, my car turned on so quickly, I have a 2006 grand Jeep Cherokee and whenever it stopped for too long, the battery dies. I tried using my cousin’s car to help me jump my car last week and it didn’t work, but this baby worked so quick and I feel so confident having it in my car.

worked great!I have a 1978 f250 and with an older vehicle you just never know when something my go wrong and drain your battery.once I rec'd the item, I fully charged it and through it in my truck just in case. To test and see if it would work well, I unhooked my truck battery, attached the clamps battery cables (again, just cables not the battery) to see if the device would jump start my truck on its own with absolutely no help from the batter (as if my battery was flat out dead) and it cranked right up!!so yes.... it works, it's small, compact, packs a punch and is great comfort knowing it's in my vehicle.

I bought this little jump starter eight months ago and put it away and never used it. Today I needed to jumpstart my 25 year old jeep that has been sitting idle for over a year and had a battery that was dead as a door nail. I remembered that I had bought this jump starter eight months ago and went and found it, and when I saw the size and weight of this thing, I thought there’s no way this can jump the battery on a six cylinder Jeep… Boy was I wrong! When I grabbed it, it was still charged to 75% and plugging it in the USB got it up to 100% in less than 15 minutes. And then I attached it to the Jeep battery, knowing that because it’s been sitting for so long and there was a slight leak in the fuel vacuum line, it was gonna have to crank for at least 10 to 20 seconds …..and holy cow, this thing handled it like a champ. Amazing product!!

I was really skeptical about this item, but I bought it anyway. my car battery died and was down for 3 days and to the point that the interior lights wouldn't come on much to my surprise it fired right up. I would recommend this product to any and all who,like me,have wondered if it really works..... IT DOES. i carry it in my vehicle all time now, just in case.
