AstroAIS8 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)

I topped this thing off then just left it in my truck over the winter. Today (nearly 8 months later) my son parked the truck at work but didn't close the door all the way, so the dome light drained the battery. He hooked this up to the truck, waited about 3 minutes, and the truck started right up. For reference, the truck is a V6, and the truck battery still had some juice left but not enough to start. He charged the charger on his way home, and it was at 100% by the time he got back. These are so cheap (get them during Black Friday or some other sale time) that I have one in every car now.

A friend of mine told me about this product after I complained that roadside assistance to jump a battery can take too long. I'm extremely pleased with it and have used it several times over the winter months. It holds a charge for quite awhile and instructions are easy to follow. It even tells you if you're properly connected to your battery. There are also ports that you can use to charge other things, like your phone. It comes with battery cables, a charging cord and even a bag to keep it all together. Relatively inexpensive and as far as I'm concerned worth it's weight in gold.

Initially I was going to give the AstroAI S8 4 stars, but it came juiced up at 75% and started my my car without needing an initial charge. Now the reason I gave it 4 stars was due to a minor inconvenience, a missing carrying bag. Two days later I emailed the company informing them of the missing bag. By lunch time, I received a message informing me they would send me a replacement asap. Three days later, I was surprised to find a new bag.As for build quality I'd give it 5/5. Now for customer service, no question, 5/5.

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.

Works as described. Used it a handful of times and it worked perfectly. Only wish the clamps were a bit more narrow since I work on a lot of motorcycles. Also works the same as my buddies NOCO that cost three times as much.

This was such a life saver to have when I was in a financial bind and couldn’t afford to replace my car battery. I was in between checks so having this tool allowed me to get to and from work for a week or so until I could afford to get an actual car battery replacement. Fast charging, very durable, light weight, quality equipment I would recommend to anyone.

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.

Update. Giving 5 stars for customer service! This specific product didn't work for me, but the company customer service is phenomenal. They reached out to me & offered to make it right, & they did! It was passed the return window, so they didn't have to do this. They really stand behind their products & want their customers to be completely satisfied. Great company & service!Did not have enough power to jump start an acura mdx. So disappointed. Got this so I would have in case of emergency.
