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.

Couldn’t be happier. Has jumped a 454 Chevy multiple times, and several V6’s in the same charge and still shows 50% battery. For the price compared to the big brands you can’t beat it! Top Don makes great stuff!

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!

愛車フォードエクスペディションがバッテリー上がり、ジャンプスターターを探してました。 いろいろな類似品もあり、口コミを読んでも機能しなかったとか、すぐに壊れたなどあり、10,000円未満の物は当たり外れがあるのだと分かりました。 この商品は、届いた時点で75%の電池残量で、これでも問題なく使えるようですが、時間もあったので100%まで充電しました。 説明書は3ヶ国語で、もちろん日本語での説明も冊子の一番後ろにあります。 早速、ジャンプスターターを5400ccのエクスペディションのバッテリーに繋ぎ、ブーストボタンON！ 当たり前ですが、一発でエンジンがかかりました。 このジャンプスターターは、パソコンやスマホ、カメラなどUSB端子で充電するものでしたら、充電出来ますので、キャンプや災害時にも活躍してくれると思います。 ただ一つだけ…本体を充電するケーブルは付属されてますが、キューブは付属されてません。
