Jump Starter Portable Car Jump Starter 12V Car Battery Charger

It worked perfectly on my v8

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.

Nice product easy to use within seconds car starts.

افضل منتج سويت اشتراك ثلاث مرات بشحنه وحده وكان التشغيل سريع منتج فويه ويستحق كل ريااااال فيه

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 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.

We absolutely love this jump starter. Every now and then my husbands truck won’t start. This little charger is a small compact size, easy to carry and use, has alot of power and a booster button to give it just a bit more oomph when jump starting the battery. I love that it’s rechargeable and doesn’t need to be plugged into an outlet to use it.

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 :)
