AstroAI S8 Car Battery Jump Starter, 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 jump starter exceeded my expectations. It’s compact, easy to use, and very powerful. It started my car in seconds without any issues. The built-in flashlight and USB charging ports make it even more practical. A reliable, high-quality product that I highly recommend.

Several times in a matter of a few months my battery on my Toyota Tundra was dead leaving me stranded in the desert. When I was considering a car battery jumper that would work for my Toyota Tundra and my wife's Honda CRV, I wanted a jumper that would not fail. My friend had a different brand I had to use to jump my truck but after some research I decided to try this unit. I purchased my first one in Jan. 2025 and tried it out on my totally dead battery on my Tundra. It immediately started my truck so I drained the battery again and it jumped my truck the second time. I was sold. So I purchased my second one in Feb. 2025 for my wife's car. To ensure the battery pack's are fully charged, I confirm the charge every 90 days. I am very impressed. Peace of mind is priceless. I will tell you their customer service is excellent and very responsive. I would recommend this car starter to anyone.

This jumper box is perfect, it’s already saved me a couple of times, and even helped my buddy out too. Super easy to use and a must-have for any car.

I love this jumper. It works perfectly. I’ve had to jump myself, and I also helped a lady at the store one day. It’s so easy to use. It holds a charge for a really long time. It says to charge every three months but if you haven’t jumped anything it’s usually still at 100%. It will use about 25% per jump. I’ve also started using it to charge my cell phone. There’s two ports on the front where you can plug your phone in. It also has a flashlight on it.I have AAA but why would I want to wait two hours when I can just jump my car battery myself? You can’t beat the price and I’m amazed that something that is slightly larger than a cell phone can jump a dead car battery with no problems. Get one! You’ll be glad you did.

It's a good little jump box. It's portable , has a flashlight and USB ports. I've only used it to jump my riding lawn mower.The only reason I'm giving 4 stars is because once the battery drops below 75%, it won't start the mower anymore until I charge it back up to 100%. I wish I could get some more power from it when the battery starts to drain.It works fine, I just have to keep it charged all the time, which might not be ideal if you're using this in a car or truck.

Quick charge and very compact. Hit the boost button and start your car. Great product at a great price.

Works as advertised. Instructions are clear and easy to follow. Looks like its good for 2 boosted uses on a full charge. Only downside is that there is no charging brick in the box. Just a cable. But it charges off a smartphone charger (15 W)

Needed a small portable battery jumper and this was it. Had a dead battery on a cat that sat for a period of time and with the booat option it started it right up. Small, portable, and powerful.
