Review: It does what it says it'll do and it does it with ease - When I bought this jump starter, I bought it solely because it was on sale and the price was good and I felt that I should probably have one in my truck... When I first saw these jump starters on the market I laughed, I thought to myself that there is no way these little things are going to jump start anything. Then I saw one jump start a big block v8 with a completely dead battery. It started that truck no problem. Overtime I eventually warmed up to them. Since buying this one I've used it extensively and it does exactly what it says it can do. I've used it to start my truck when my battery was dying are used to start my jeep and I've used to start many of my neighbor's cars. As well as just random people that needed a jump. The battery life is missing is great I don't charge it very often so I can picture most of the time but I've never had it not start the intended vehicle because the battery was too low, I'd use it as many as 5 or 6 times without charging. The only complaints I have about it is the little 12 volt cigarette lighter adapter plugin that came with it is practically useless but outside of that it's a great product
Review: Excellent starter, highly recommended - I bought it to keep in my car for emergencies, and so far it's worked great. The materials feel solid, and the clamps have a good grip. The battery holds a charge well and also doubles as a power bank for charging my phone. The LED flashlight is a great extra for nighttime use. The device is compact and easy to store in the car. For the price, it offers excellent features, and I have peace of mind knowing I have it with me. I would definitely recommend it.

### ⭐⭐⭐⭐⭐ Excellent product!
*by O***D on October 20, 2026*

My neighbor borrowed this to start an old Chevy Silverado that had been sitting for months without being started. The truck fired right up when connected this. He moved the truck to get it out of the way of some activity and then shut the truck off. So, when he went to move the truck again he needed to use the AstroAI again to get it started. In total he used it three times and it worked every time. It consumed about 1/3 of the device's energy. I have it recharging via USB cable from my computer. This is exactly what I wanted for emergency use. I'm pleased with this.
