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)

My 2011 Lexus Hybrid was sitting for 3 months. I called AAA for a jumpstart. The technician told me to drive it around town, preferably the parkway, to give the Hybrid battery what it needs. I tipped him $20 and he was gone. I drove it maybe 30 minutes around the neighborhood. The next morning, it would not start. I went on line and found this beauty, nicely priced with same day delivery. It was waiting for me when I returned from work. It was charged 3/4 out of the box so I plugged it in for a full charge, followed the directions hooking it up to my car’s battery, made sure to press the boost button and voila - a super quick charge. This little doozy has power! I did drive it on the parkway and around town for a solid hour and all is well! I purchased one for each of my children to keep in their cars. It’s a solid instrument & a total must have; easy to store in the car in its carrying case (which is included). Oh, and the flashlight feature is a real bonus. As long as you keep it charged, it’ll save you a load of money and hassles when you need it! My only regret is not purchasing this before calling AAA.

This thing works! I have used it five times now. People at work made fun of me when I said I could use this so the didn’t have to shuffle vehicles around to jump a buddy’s truck. I connected it up and told them to turn the key and it fired right up. Just today I leave work to drive home and my battery was dead. Connected this thing and pressed the boost button, turned my key and my truck fired right up. It got me to an autozone so I could buy a new battery. Life saver this thing is! Get it and you won’t regret it.When using it multiple times the battery will drain quickly. Keep it charged and don’t forget about it! I got 5 jumps out of one full battery. It’s now charging since I used it and then it goes back into my truck.

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.

Since buying this item I always travel with it and have used it on other vehicles at least a dozen times maybe more. Its been a life saver and provides the jump start each time. I also has excellent power.

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.

Very happy. Easy to use…changed it and then jump started my spare vehicle. It started right up. Now, I don’t have to wait for AAA… I can handle it on my own. It’s a well-built, rugged unit and handled the job perfectly. I didn’t need to use the boost button, but it’s good to know it’s there in the event the vehicle battery is stubborn.

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.
