AstroAI S8 Car Battery Jump Starter 1500A – Portable 12V Lithium Jump Box with 3 Mode Flashlight, Power Bank & Smart Jumper Cables - for 6.0L Gas and 3.0L Diesel Engines

Great car jump starter. It’s powerful, compact, and very easy to use in emergency situations. It starts the car quickly without needing another vehicle, which gives a lot of peace of mind. The battery lasts a long time and it’s convenient to keep in the trunk or glove compartment. It also includes useful features like a flashlight and USB charging ports. Very reliable and a must-have for any car owner. Highly recommended 👍

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.

Works great. Ideal for a quick jump start. Can be charged at home. Atleast 4 jump starts on a single full charge. Comes with a comfortable carrying case. Easy to carry, easy to use, clear instructions for safety.

Did a simple test, had my old 12v agm for my boat down to 10v and less than 200 amps on the meter. Decided to test out my new 1500 CCA asrtoAI S8. Hooked the dead battery to my boat, hooked the AstroAI jump starter up and boosted battery for a short while then followed the instructions and started the boat right up!! Product works great. Good quality, durable cabled and connections, type C USB charge port, easy to use! Astro AI send me a 5000amp unit to test out and review!

Purchased this unit over a year ago on a whim. Very impressed with its ability to start a number of different vehicles, ATV’s, a snowmobile and a couple garden tractors. I wish the clamps were a little less bulky to fit in tight spaces and they had about 12” more length in the cables. Definitely works as advertised.

⭐⭐⭐⭐⭐ I purchased this AstroAI S8 Jump Starter for my vehicle and honestly it’s one of the best car accessories I’ve bought. It’s compact, easy to use, and powerful enough to start my car quickly with no issues. I love that it doesn’t take up much space in my trunk and gives peace of mind for emergencies. Definitely worth the money! It also works as a power bank for charging your phone

The best charger ever! Easy to use. Portable...fits under my seat. Almost instant start. There's a feature to give the battery and boost and then turn the key again. It's magical almost. 5-IN-1 MULTIFUNCTION Versatility- This device functions as a jump starter, portable power bank, and an LED flashlight with 3 modes (flashlight, strobe, SOS). The AstroAI Lithium Battery Jump Starter is your reliable, all-around trip companion here to gear you up for every adventure. That's a quote. I haven't used all of these features yet. I can be recharged right there in my truck with the 'cigarette lighter'.

Perfect product. Compact, Light, and work very good, very goog speed charge.

A compact unit that easily starts your car. Car battery went dead and started the car no issues. Had to stop on way to garage and unit started me again with 2 lights still showing as a charge level. Handy to keep in the boot to get you out of those surprise moments when your car surprises you with a flat battery. Why did you choose this product over others?: Compact and has already proven itself. Battery life: Can't fault this item started my car twice and still had some life left. Charging capability: Easy to charge and holds it's charge well. Says to charge every month to keep it topped up but.kust say forget about this and a few.months on it doesn't seem to have dropped any battery life. Car start: Started my car twice without needing to be charged Well worth the money for that reassurance should you need it and stall your car it will get you up and running again. Build quality: Well built solid unit, clear instructions and good quality clips for the battery connections. Compactness: Small but powerful. Compact and can fit in you glove box or boot.

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 👍

funciona muy bien, se descarga rapido máximo 2 arranques y ya no tiene batería

Das Gerät ist einfach genial und macht genau das, was es soll, nämlich Starthilfe bei entladener Batterie geben. Wer hier negativ bewertet, der hat irgendwas falsch gemacht. Die Verpackung ist sehr edel, das Gerät auch, alles hochwertig und optisch ansprechend. Mein Mercedes A180 1,6 Liter startete nach 4 Monaten Standzeit und Überwinterung nicht mehr. Die Batterie hatte nur noch ca. 10,5 V statt 12 V. Also bestellte ich mir dieses Gerät hier. Es wurde sogar mit 100 % Akkufüllstand geliefert. Ich habe es gemäß Anleitung direkt an die beiden Batteriepole angeschlossen. Nach ein paar Sekunden erkennt das Gerät dann, dass es an eine KFZ Batterie angeschlossen wurde und die Connect LED leuchtet grün. Erst dann gibt es 12 V aus. Ich habe zur Sicherheit noch den Boost Knopf gedrückt. Man muss ihn kurz gedrückt halten, dann klackt es und dann kann man los legen. Da die Connect LED aber nicht grün blinkte, sondern grün leuchtete, war die Batterie nicht Tiefentladen und der Boost Modus wäre nicht unbedingt notwendig gewesen. Aber ich dachte mir viel hilft viel :D Danach habe ich die Zündung angemacht und das Fahrzeug startete sofort ganz normal ohne jegliche Verzögerung :) Anschließend hatte die AstroAI noch 75 % Akkufüllstand wie auf meinem Bild zu sehen ist. Ich gehe also davon aus, dass man mind. 4x Starthilfe mit Boost Funktion geben kann, ohne Boost wahrscheinlich öfters. Das aufladen mittels USB-C und meinem Smartphone Schnell-Ladeadapter ging auch recht zügig. Ich lade es jetzt immer voll und lege es dann für die nächste Panne in den Kofferraum. Da ich bald wieder in den Urlaub fliege und mein Auto dann am Flughafen stehen lasse, fühle ich mich jetzt mit der Starthilfe im Kofferraum auch deutlich sicherer. Fazit: Ich bin absolut zufrieden und konnte mir so den Batterieausbau zum externen laden sparen und das alles für nur 35 €, echt top :)

L'oggetto è arrivato rapidamente come consuetudine Amazon. Lo stesso è dimensionalmente leggero e facile all'utilizzo, corredato da comodo sacchetto contenitore, cavo di ricarica e di collegamento alla batteria dell'auto, manuale di istruzioni multilingue compreso italiano. Semplicissimo da usare è stato provato su veicolo con batteria scarica, dopo due tentativi si è avviato. Il booster deve essere carico al 100% per ottimizzarne la funzione, si ricarica velocemente. Ottimo acquisto.
