AstroAI Jump Starter Portable Car Jump Starter 12V Car Battery Charger

It worked perfectly on my v8

Nice product easy to use within seconds car starts.

I got it to help jumpstart my VW PASSAT V6 as the battery was completely drained while the car was parked for ~ 2 months. The unit was at 50% battery when received. The manual is great, simple and straight forward. I followed the instructions in the manual. It took approx. 1 hour to charge it via my phone's USB-C fast charger up to 100%. It took 2 attempts to start the car. The 2nd attempt was because I didn't wait the 30 seconds as per the manual's instruction in handling completely drained batteries in my 1st attempt. On the 2nd attempt, I followed the instructions for completely drained batteries and the car started smoothly. Both attempts used ~25% of the booster battery capacity. Over all, the package is great in size and weight. I like the idea it came with a small bag to house the booster and cables. The booster uses USB-C for charging. No more jump start cable hassle and no more waiting forever for insurance recovery.

This jump start kit was perfect and it helped alot of my friends. I havent tried it on mh car yet. But ive helped alot.

Awesome device a must have.Highly recommended

One of the best device ever used

Only used it 3 times and already stopped working and won’t charge. I’ve kept it charged and in my car. Not worth buying this

Wow, this astroAI S8 battery booster is the real deal! I used it to jump my car and it worked like a charm, starting my 4L engine right away. Seriously, I was impressed because it even got my 75 Amp battery going on the first try. If you're looking for a reliable jump starter, I highly recommend this one; it's a lifesaver. Definitely worth the purchase!

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 👍

I am beyond impressed with this jump starter! It’s compact, easy to use, and has been a lifesaver on multiple occasions. The first time I used it, my car battery was completely dead, and this device started my vehicle in seconds—no need to wait for roadside assistance or ask strangers for help. The build quality feels durable, and I love that it also doubles as a portable charger for my phone and other devices. The instructions were clear, and the included safety features gave me peace of mind while using it. Even in colder weather, it performed reliably, though I did notice it worked best when fully charged. Overall, this is an essential tool for any driver, and I highly recommend it to anyone looking for a reliable, portable jump starter. Five stars without a doubt!"

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.
