The media could not be loaded. I bought this AstroAI S8 car battery booster as a gift for my sister, whose car battery tends to go flat because she doesn’t drive often enough. From the moment I opened the box, the quality of the product was immediately apparent. The build quality is evident straight away, instilling confidence that it’s designed to last. The packaging was sleek and stylish, and the unit arrived nearly fully charged, which was a pleasant surprise.Knowing my sister needed something reliable, I was eager to test it before she had to rely on it in an emergency. The jump starter surpassed expectations right from the beginning. We tried it on her car with a flat battery, and it worked flawlessly on the first attempt. Each jump start uses about 25% of the booster’s battery, but keeping an eye on the remaining power is straightforward thanks to the bright blue battery status lights. The unit is also very easy to charge using the included USB cable. Its ease of use is a major highlight. Just connect it according to the clear instructions, and the car started up in seconds. This level of convenience is a significant improvement over traditional jump leads, allowing her to be completely independent and avoid the awkwardness of asking a neighbour or stranger for help to jump-start the car. The clamps and cables are incredibly tough and durable, feeling nice and tight when secured to the battery, unlike the jump leads I’ve used in the past.The compact size of this booster is another strong point. It’s small enough to fit neatly in her older Fiat’s glove compartment without taking up much room, yet it packs a powerful punch. Despite initial doubts about whether such a compact device could handle an older battery, it performed admirably, even in cold weather when batteries are typically more challenging to start.Over the past month, she’s had to use it multiple times, and it has proven to be a dependable tool. The built-in LED torch is another thoughtful feature, making it easier to operate in dimly lit conditions, like early mornings or late evenings. The fact that it also doubles as a power bank for charging mobile phones adds even more value to an already impressive product.Considering its price, the AstroAI S8 offers exceptional value for money. Not only is it affordable, but it also delivers high performance, making it a smart choice for any car owner. Given that a single call-out for roadside assistance can cost twice as much as this booster, investing in one is an obvious decision and well worth every penny.The delivery was fast, and the overall service was excellent, making the entire purchase experience smooth and satisfying. I’m so impressed with its performance and build quality that I’ve decided to order one for my car as well. If you’re in the market for a reliable, powerful, and well-built jump starter, I highly recommend the AstroAI S8. I could kick myself for not buying one sooner.Thank you for taking the time to read my review. I hope that you found it helpful and that it assists you in your decision-making. I try to be as honest and fair as possible, as those have always been the reviews that helped me the most.

After having to work away from home for over 2 months. My car was left unused and its battery had drained. This jump starter saved me when I returned, to my surprise it arrived the next day to a click and collect counter. And the jump starter was already charged up to 75% out the box. To be on the safe side I plugged it in and it was 100% charged in less than an hour. The instructions had a handy guide that tells you the red lead goes to the + terminal and the black lead goes to the - terminal. Apparently the jump starter would automatically detect if the crocodile clips were placed the wrong way around but I didn’t test this. After a few seconds my car engine miraculously started. For its cheap price I really can’t complain, having done its job it is excellent value for money compared to other jumpstarters that are 2 or 3 times the price. It’s a compact size, about the size of a large USB powerbank (which it technically is) and would fit in a glovebox of side storage in the boot or door pocket. My only slight criticism is the cables are a bit short but it still did the job resting it on the engine cover and it took me a minute to find the boost button on the side of the crocodile clips.

Good piece of equipment,, very handy for jump starting instead of bulky leads. Small and lightweight but packs a punch. I have used it half a dozen times to start vehicles with a dead battery but I found I had to charge it after every use as there wasn't enough power for the next vehicle, however the vehicles I was using it on where completely flat. It's also well made and quite sturdy.

I noticed this product is much cheaper than equivalent products that do the same thing.Context of why I bought it:My son had a car delivered it hadn't been driven for two months. Dead of winter. The battery was dead. Not so much as a noise when turning the key.I mulled over calling the garage out but decided having one of these might be useful going forward.It arrived charged. I put a few more volts in and connected it up.Car turned over first time. Thing pretty much paid for itself right there and then.Because I never took the car for a long drive battery died again overnight.Same thing next day. Dead battery but using this it turned over first time.It now lives in the glove box and I get real peace of mind from that. My son is only young.Bonus functions - torch, usb and usbc charging capability.So, from my limited use it’s been a superb investment.Details.Car I used it on, only a little 1.0 litre engine ( so tiny).Use was almost out of the box so can’t comment on how well it holds a charge over time, for example if it was left in the boot.Great bit of kit. My experience has been nothing but positive ( battery joke in there somewhere..).
