JS3000 12V 3000A Battery Booster Jump Starter Pack for Up to 9L Gas/ 7L Diesel Engines, Portable Car Battery Charger with Handle Jumper Cable and EVA Protection Case

There's nothing worse than getting stuck with a dead car battery, especially if you're busy and on a schedule. You can't always rely on someone nearby having jumper cables, either. And you definitely don't want to spend the money to get a professional if you can help it. That's why being self-reliant and getting your own portable jump starter is so important. As soon as your car battery dies, you can get it up and running almost as quickly with a jump starter. After browsing through the bazillion models available on Amazon, I went for the Topton JS3000, which looked like something substantial that can have enough power to start my old F-150. And, I wasn’t disappointed. The jumper comes in a very nice hard shell style transportation/storage case, and contain everything needed to be ready to use it. Even the USB power block, which is often missing on other models. Talking about USB, this battery jumper devices have USB ports as well, and we often use this in our garage as an oversized battery bank as well when not used to jump start anything, to charge phones and the like, so it’s very useful in all sorts of emergencies. Using the device was very easy really. After being sure it has a full charge, I just plugged it to my truck’s battery, and it immediately detected it and turned one automatically. All I had to do was crank the engine, et voilà, the truck started right at the first try! Once fully charged, I can store this device in my truck, and forget about it for six months or more, until the next time it’s needed. They do however need topping up occasionally, especially if they get very cold or very hot repeatedly. So, something to keep in mind to avoid having a battery jumper that will have a depleted battery, just at the most needed moment. There are other little details that make the JS3000 easier to use. It turns on with a single short press to the power button, as does the embedded flashlight, which cycles through multiple on and emergency flashing cycles. Other units I owned in the past required assorted long and confusing sequences of presses, which might protect against turning on accidentally, but was a hassle when I actually needed to use it. Like every other lithium jump starter, it has of course a reverse polarity detection, alerting you if you connect the clamps to the wrong battery terminals. Keep in mind that the best time to think about shopping for a portable jump starter is not when you’re stuck by the side of the road with a dead battery. Compact, affordable, and easy to use, the latest lithium-ion chargers like this one could be a life saver, and are also small enough to fit in a glove compartment or under the seat, yet it can start your car (or truck) without jumper cables or waiting for help. Definitely a recommended purchase, which I am happy with.

This bumper box is awesome for the most part. It’s compact enough to carry anywhere- fits under a seat or in a trunk no problem. Like stays on the top of my tool box. Cable length is long enough to reach even heavy duty top wing nut batteries. It works, and it works AMAZINGLY WELL. Attach the cables and the unit auto detects the battery. If it’s low, hold the boost button and start the vehicle. You have about 15 seconds of start time before the boost feature disables. The limited boost time is one of the things I don’t like about it. The jump pack stops throwing voltage after the boost cycle, meaning that if the battery doesn’t have enough charge, everything shuts off. It would be nice to have a fast charger to come with it. That being said, this thing is an awesome value for the money. It started a completely dead 6.7 powerstroke f450. I mean completely dead- oth batteries had 1.5 volts. It started a 7.3 powerstroke that has been sitting on the lot for 5 years. I had to use the pack twice, because the first time was just for fuel priming. Started the truck up both times without issue. If it’ll do that old 7.3, it’ll do any regular vehicle you want it to. It also has emergency lights, and can double as a power pack.

The power that this jump starter packs is simply impressive. With 3000A, it can jump-start engines up to 9L for gas and 7L for diesel. This means that not matter if I'm in my own car, a friend's vehicle, or even a larger truck or SUV, this jump starter has got me covered. It's very portable which is a huge plus. The compact design and the handle make it easy to carry around. It's lightweight enough to throw in the trunk or even keep in the backseat without taking up too much space. The build quality is top-notch. The jumper cables feel sturdy and durable, and the EVA protection case is well padded and sturdy so great for storage and transportation. The versatility of this jump starter is also amazing since it doubles as a portable power bank, equipped with USB ports to charge smartphones, tablets, and other devices. It's like having multiple tools in one compact package. Overall, excellent performance, portability, and reliability. It's a must-have always in the car. Highly recommended!

Really impressed how well this boost pack works. I've only used it twice so far since I received it but so far it's worked beyond what I expected. Both vehicles I jump started were completely dead. First was a 4.0l Nissan Frontier and second was a 4 cylinder Honda Civic. Cranked both over like I installed brand new batteries. I haven't jumped an 8 cylinder or diesel yet but I'm confident this pack will work fine for the vehicles I'll be using it for. Hope long term it will perform. Time will tell. Came with a case, charging 120v usb block, usb c cable, and 12v large jaw jump cable

I am one of those people that research the heck out of everything which is why several people I know copy what I buy lol I spent hours looking at products and reading reviews, and this one seemed to have most of what I thought was good, especially after reading reviews of people that are mechanics or work with cars or by auction cars and are constantly trying to start them and move them around. One of the things I took away from the reviews is it’s nice to have it plugged directly into the charger and not have that extra little box in between that could cause issues at some point. Then there’s the issue and fear of overheating , this one has so many safety features that I think you can feel pretty safe the clamps are heavy duty, and it comes in a very nice hard case unlike some of the other ones. I like that it has an on and off button because one review I read another charger did not and the person thought that was good, but to always have it in some kind of ready mode sounds dangerous to me. Some of the other chargers people had problems with the boost button if it even came with one that it was a small button that was hard to access or push in. This has it right on the top and the indicators that let you know if you need to use it. The case has a carrying handle, the charger has a carrying handle and a hook and a stand. There’s nothing not to like. It came in 75% charged and went to 100 in no time. There was almost no detectable heat at all given off during the charging. They do have a lesser model (a 2000) but it has that in between box connector that I didn’t want, from what I read I think direct connection is best. Peace of mind since my Toyota continually draws from the battery as they do (2009 4Runner) used to be dead after about five days of not driving. Then I got a better battery than the AAA kind that’s lasts 2.5 yrs and can still strand you right after driving. I believe it was called EFG that is more powerful and I can easily go a week and a half without driving it. I have not pushed it past that but that battery also changed my life. Now I’m set and I don’t think I will be stranded anywhere!

The best jump box ever. Skid steer battery dies while out on a job and it started it easily. F250 also had issues from sitting in 22 degree weather and it worked flawlessly.

Good product ,never let me down yet and i ordered it about a year ago

I acutely bought this one thinking I was buying the next level below this. Well I can say I’m glad I did. It jumped started a f450 diesel that has sat for 3 weeks, it’s jump started a side by side, the flash light is per dang bright.

Sehr gute Qualität

Una compra muy eficiente y funciona perfectamente y de muy buena calidad

Good

Bon un booster c'est un peu comme un extincteur. On ne s'en servira pas forcement, mais quand on a besoin c'est trop tard pour l'acheter ! J'ai choisi un produit de marque pour ses performances et j'espère sa durabilité l'avenir le dira... C'est en plus d'un booster une power Bank très performantes pour les smartphones, mais pas seulement. De même l'éclairage est puissant et durable (important en cas de panne ou accident sur la route de nuit). Au vu du produit et a sa tenue en main on a vraiment une impression de solidité. Un chargeur USB est fourni. La sacoche est robuste. la notice est claire mais il manque des (une) informations importante : Ne brancher le booster que le minimum pour démarrer, car en plus du courant de démarrage le booster va charger en même temps la batterie avec une intensité bien supérieure a ce qui est préconisé pour sa durabilité. Le role du bouton « boost » n'est pas suffisamment détaillé et explicité ( son rôle est mal compris par 99% des youtubeur qui testent le produit). De même pour la durée de vie de la batterie du booster il est il est fotement déconseillé de l'utiliser lorsque sa charge est 50% ou moins . Toutes ces choses sont dites dans la notice mais les conséquences du non-respect ne sont jamais dites clairement (diminution de la durée de vie des batteries (boster et batterie du véhicule) .

Genuine powerful jump starter. Also It can start heavy truck too not any issue. Awesome powerful product
