S8 Ultra 12V 4000A Lithium Jump Starter Up to All Gas/12L Diesel

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

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.

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.

Good quality at a fair price. I purchased their multimeter and the quality led me to purchase the jump starter above all the others.

I have used this on multiple occasions to jump start three motorcycles and a pickup. Each time, the people I've helped have been astounded that such a small device could start a large engine. Everyone should have one of these and I highly recommend it!

it's very nice , it has long cables, and the lightis also nice.

It’s worth pretty good I like it

This booster has been a lifesaver. It’s come in handy a few times already. It’s so convenient and easy to use. It’s got plenty of power to get you back up and running. I’m so glad I bought this booster.

Bought this as my Land Rover with a 2.5 turbo diesel engine had a flat battery, slightly turned the engine over, but not enough. I tried jumping it with another car and it still wouldn't start. It was away from my house so couldn't run the battery charger to it. So power jumper pack required. There are many on the market so it was what's best value for money, this was being sold for £37.99, an excellent price and mid power range. I was a little skeptical to be honest about it, but it started the engine first time. It did require charging when delivered, I did this over night . It dropped one bar after starting the engine, out of 4 bars, but would of done a few more starts I'm sure. I will keep it in my Landy just in case and keep it charged of course. It saved me having to call out recovery so I'm very happy with it, best purchase for many a month.

My car battery was dead, and someone happened to have this jump starter with him. It started my car instantly, and he highly recommended it to me. I ordered the exact same one from Amazon. I would recommend it to anyone looking for a reliable jump starter.
