About this item

  • HIGH-PERFORMANCE JUMP STARTING - This jump starter's powerful 1500 A peak current quickly starts low-voltage and fully-drained batteries. This jump starter battery pack has a 45 C high-rate lithium battery that can start 6.0 L gas/3.0 L diesel engines and other 12 V vehicles like motorcycles, cars, SUVs, pickups, or lawnmowers.
  • ULTRA POWERFUL BOOST - The smart boost mode automatically detects the battery's voltage. When the voltage is less than 9 V, the indicator flashes green; this unlocks the "BOOST" button, which can be pressed to start fully-drained batteries.
  • ORIGINAL CHARGER FOR IMPROVED PROTECTION - The included original 10 W wall charger better protects the S8 Car Battery Jump Starter from excessive heat damage, loose ports, battery bulging, battery expansion, and more.
  • COMPREHENSIVE SAFETY - This portable lithium car jump starter has 8 integrated protections including reverse polarity, reverse connection, overcurrent, overvoltage, overload, overcharge, over discharge, and short circuit protection. Ensure your trip is safe and smooth.
  • PORTABLE & COMPACT - With an overall size of 7.9*4.5*3.7" and a item weight of 0.95 lbs, it is very easy to store in a car or a travel bag. Compared with bulky lead-acid jump starters, this compact jump starter brings more convenience and peace of mind to your trip.

5.0 out of 5 stars Works great!
Reviewed in the United States on April 10, 2024
Color: OrangeVerified Purchase
My car battery was 7 years old and would no longer hold a charge, but would start with a boost. I had a hard time finding a place that had my weird battery in stock, and that took a few days.
Meanwhile, I got this from Amazon. When I turned it on, all 4 bars lit up, which was nice. I used it 3 times before I was able to purchase a new battery for my car, and each time it was super easy to use, and my car started right up. Lifesaver!
It's also nice that you can plug it in and charge it up while you're at home.
I found it takes about one hour per light bar, so 4 hours total charging if it's completely drained.
Very happy with this purchase.

My mom lets her car die or needs me to jump a car for her all the time so I figured if this worked well enough it was worth the price. I was wrong thinking this wouldn't work that well because it is POWERFUL.

She had a car sitting since 2020 and was trying to get it to start, the battery can't hold a charge but I tried this just to see and it would keep a long dead battery running until the boost shuts off after a few minutes. We couldn't get that car to start at all with any other kind of jumper cables or different car batteries to jump it from.

This would be a great item for your emergency kit as long as you keep it charged.

I recently purchased a portable car jump starter from Amazon, and it has been an absolute lifesaver! Let me tell you about the time when my 4Runner's battery died and I found myself in a tricky situation. I couldn't get another car positioned to jump-start it, and I started to panic. But then, this amazing jump starter came to the rescue and saved the day!

One of the things that impressed me the most about this jump starter is how compact and easy to carry it is. It's incredibly lightweight and doesn't take up much space, making it convenient to bring along on road trips.

But what really blew me away was how quickly this jump starter connected and started my 4Runner. Within minutes, my car was up and running again, and I was back on the road without any hassle. It's a game-changer for those unexpected moments when your battery decides to give up on you.

Not only did this jump starter save me from being stranded that day, but it also gave me peace of mind knowing that I won't have to rely on someone else to jump-start my car in the future. I feel empowered and independent, knowing that I have a reliable backup plan in case my battery dies again.

To top it all off, the delivery from Amazon was incredibly fast. I ordered the jump starter, and within 24 hours, it was at my doorstep. The convenience and efficiency of the entire process added to the overall positive experience.

In conclusion, I highly recommend this portable car jump starter to anyone who wants to be prepared for unexpected battery failures. It's compact, charges quickly, and has the power to save you from being stranded. Don't wait until it's too late - invest in this jump starter and have a safety blanket with you wherever you go!

I used it tonight. It was fully charged.

I did as instructed except I connected the black to my car ground.
The lights turned solid green so I did as it says and went to start my car.
Did not work.
Disconnected ground and put the black on my negative terminal.
The light turned green.
The car did not start properly.
Went back and pushed the Boost button and thought I heard a click.
According to the instructions boost is only needed if the light blinks green not if it is is solid.
Maybe you are supposed to push it regardless.
At this point I was down to one bar.
Anyways, my car started.
So now I am recharging it.

The instructions say to keep it charged over 75 %. I would agree as looks like each attempt drew about 25% +.

Also I was using this on a plug in hybrid which does not take many Cold Cranking Amps to start.

I also am keeping a small sealed lead acid battery in my car as my battery has been unreliable recently, but thought I would give this a go.

I think it will be useful as a back up charger for my phones.

It did work though so pleased about that. Not sure if I am completely confident it will work on a regular car, but I cannot say it won’t.

It is nicely made. Very lightweight. Feels good quality.

Things I like: 1. Size, it is around the size of a 150 count dryer sheet box. 2. Simple operation. 3. The flashlight works well while under the hood. 4. It can handle jump starting the motor of my 2001 triton Ford Expedition.
Now for the things that I would like to be improved but aren't deal breakers. 1. The charge time and temperature limitations. I planned to leave this charing in my garage but it asks for you not to charge in temps over 90 and being in Texas that will make me charge this inside. The charge time of this pack is a bit high at atound 4 hours, but also not a deal breaker. Overall, I will be buying again if needed.

Absolutely perfect! Charged straight out of the box, the instructions were easy to follow, and within minutes, I successfully jumped my Mercedes CLS 3.2. It also includes other handy tools, and its compact, lightweight design makes it easy to carry. This product is a winner—you can't go wrong with it.

Kurz nach dem Kauf war die Situation da, daß ein 2.3 Liter Turbodiesel nicht gestartet hat.
Zu wenig Strom von der Starterbatterie.
Diese Powerbank entsprechend der Anleitung angeschlossen, grünes Licht bekommen und der Motor hat im ersten Anlauf gestartet.
Danach wieder aufgeladen, wobei gerade mal ein Licht von der Ladeanzeige weg war.
Die Powerbank ist erstaunlich leicht, funktionert aber sehr gut, auch weil alles dabei ist was man braucht sowie unter anderem eine deutsche Anleitung zur Benutzung.

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 👍

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.
