I purchased the AstroAI S8 Car Battery Jump Starter for my daughter’s first car, and honestly, it’s one of the best “parent purchases” I’ve made. Knowing she has a portable car jump starter in her trunk gives me real peace of mind, especially as a new driver still learning to handle unexpected situations.The AstroAI S8 jump starter battery pack is compact, lightweight, and easy to use—even for someone with zero car experience. We tested it at home, and the instructions were clear and straightforward. It’s impressive that this 12V portable jump box can handle engines up to 6.0L gas and 3.0L diesel, which means it’s more than capable for her car and even mine if needed.I also really appreciate the built-in 3-mode flashlight (flash, strobe, SOS). That feature alone makes it a great safety tool, especially if she’s ever stuck at night. The jumper cables feel sturdy and well-made, not cheap or flimsy like some others I’ve seen.The bright red design makes it easy to spot in the trunk, and the battery holds a charge well. This car battery jump starter is now something I recommend to every parent with a teen driver—or honestly, anyone who wants to avoid being stranded.Reliable, easy to use, and great value. The AstroAI S8 Car Jumper Starter Battery Pack is a must-have for first-time car owners and families alike. Highly recommend!

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!

Well this thing works. I have GMC Acadia, my car battery has been getting weaker and weaker when I would go to start it in the morning. The colder it gets the worse it got. I figured I try this, charge it up and keep it in my car as I knew my battery life was very limited. Sure enough all I got was clicking, my battery was dead, it was 5 degrees outside. I hooked this up to my battery, was very easy, and so much better than needing another car to jump it. I waited a minute, went to start the car and got nothing. I was nervous at this point that it didn’t work. I readjusted the positive cable as it just looked off and tried it again. The car started right up !!! I was so glad I thought ahead and got this thing. This charger is great, small enough to fit in my glove box if need. Great design and packs some power to start a pretty much completely dead battery. 5 stars for this one.

5.0 out of 5 stars Very nice.

Acheté pour faire démarrer une batterie sur une 308 Diesel (de 2012), ça fonctionne parfaitement. J'avais une crainte pour pouvoir trouver un endroit pour mettre la masse car le câble est très court et sur ce modèle de 308, la masse de la batterie n'est pas accessible (seulement le plus), mais impeccable, j'ai pu trouver vers le capot de quoi mettre la pince noire sur la carrosserie pour faire masse.Et démarrage du premier coup 👍

this battery pack jump started my 2010 sedan in just a few quick minutes from being completely dead. i was able to jump off my car twice within a short period of time (i had a camera that was draining it). the reason i docked one star is that it does drain battery very quickly. it comes in a small bag to keep it and the charger in which is nice.

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.
