When I took the AstroAI S8 out of the packaging, I looked at the unit and said to myself "you're kidding me this will never work but whatev's I'll give it a try". Boy was I wrong, this jump starter nails it every time. Early am, I took my dogs to the beach, returned, opened the lift gate, the pups jumped in and that was it, out of nowhere the battery died.....literally nothing was working. Got a jump and was back on the road. Back home, left it over night same thing. Luckily, I thought this would be a good time to buy a jump starter, cause you never know. I'd been toying with it for a while and already have a tire inflator/pressure monitor as a 'just in case'. Honestly, I didn't expect this to happen again but it did. My car is only a few years old, it's a BMW X5 4.0i. The jump charger not only needs to be able to crank & spark the engine but power-up all the monitors/heads-up display/driving/safety/management/seat passenger detectors/climate/level & motion sensors and way more stuff/systems in tandem with cranking the engine. By-Jove....it can do all of it, the car starts without any hesitation. Unfortunately, from a dead battery, the default is for all the electronics to fire up at once, so there's no 'lite start' option. I was really surprised. Useability is a sinch. Plug-in the jumper cables to the AstroAI S8 unit, pop the hood, connect the cables to the vehicle contacts (a tiny green LED by the Boost button start flashing), press the 'Boost' button at the base of the cables, get behind the wheel and start the car. I couldn't tell the difference between the jump start and regular start. It can even start the car with less than 75% charge. I can expect at least 4-5 starts from the device. It charges from a standard USB port (USB A) and when it's fully topped-up it stops charging. I'm not sure if this makes a difference but I should point-out the car was jumped from designated contact points, not the battery. Also, as soon as I press the 'boost' button I can hear the car come to life and go through some sort of boot-up. By the time I get behind the wheel, my key is detected, everything is as normal and start the vehicle. There was an instance whereby the alarm went off, I just hit 'unlock' on the fob and that did the trick. On the downside, the jumper cables seem a little short (I had no problem reaching my car's contact points) and you will have no problems jumping the battery directly. Although, I've see in some vehicles the contact points are more than 18in apart, this will require some sort of extension. As a blanket synopsis: The AstroAI S8 works great, it easily starts a super systems-power hungry vehicle w. a 3.0 inline 6.

Can I give this product ten stars?! My truck had been struggling to start, and I ended up calling AAA twice in one week for jump starts. I saw this product on Amazon and debated whether to buy it, and finally decided to purchase it. When my truck didn't start again today, I pulled out my jump starter—and it fired right up instantly! I was honestly skeptical because the device is so small, but it delivered immediate results. It’s simple to recharge (just plug it into any USB port) and comes with a convenient pouch that fits perfectly in my truck for easy storage. The jumper cables are just the right size and feel well-made. It even includes a built-in flashlight, which I didn’t need this time but can definitely see being useful in an emergency. This jump starter is worth every penny for the peace of mind alone. I’m so glad I bought it!

I bought it for the lower price, safety features and positive reviews. I am impressed by its quality and usefulness. I am a van lifer and this jump starter is a must have! It jumps my van battery faster than using another vehicle does. It's super simple to use, fast, safe and reliable. I was told to get one that is twice the price but couldn't afford it. This one is just as good and does the job perfectly. If you're considering purchasing this jump starter I highly recommend it.

Compact but very mighty. 3 in 1 gadget with a flashlight, backup phone charger battery, & battery jump starter. You can get a good amount of uses on one charge with a light indicator to show the leftover charge on the battery. Starts my trucks and cars right away. We have bought 2 because the first one was very good. Well thought out design to help you when your battery gives out as well as access to charge your phone in case you need an emergency tow or call

Used for the first time in the Texas cold of 55 degrees. Had a full charged and took two attempts as first time pressing boost only slowly spun motor. Second time pressing boost it spun my motor fine but only showed 25% battery remaining. Had no trouble starting a 6.2L gas v8 with moderate aftermarket cam Worth the buy for the price and can comfortably say it should have no problem starting most normal v8 trucks

Excellent product! Compact, would fit in the glove box, but I've been keeping it in my purse so as not to leave it in a cold car. I bought it just over a week ago and it has saved us three times already (my car is having issues that drain the battery, exacerbated by the cold weather). The charger came partially charged, but I charged it to 100% before using, and each time I used it it used 25% of the charge. I haven't tried using it at 50% or lower yet though. The best part is that it's super fast, way faster than jumping from another car - just plug in the jumper cables, attach them, and the car turns on right away. Very happy with this product, I would recommend to others!

This works so darn good! My car needed a jump and it started right away. Definitely worth the money!!!!!! It charges pretty quick too. It comes in this cute little black bag so you can store it in. I actually put it in my glove compartment, bc if my battery dies it won’t let me access the trunk. Nice and compact, and also has a built in flashlight as well.
