JNC345

This thing proves its use time and time again. I have a few vehicles and they sit and require jumps quite frequently. This thing always gets them started and it has enough battery to do it over and over again before it needs a charge. I’ve charged it maybe twice or three times and I think I’ve used it at least a dozen times if not a little more. It’s compact and lightweight good quality and I think it’s worth the money…it’s lightning fast as well..

I bought two of these — one for each car — and I’m beyond impressed. They replaced my older, bulky jump starters that used standard sealed batteries. The JNC325 is significantly lighter, occupies much less space, and still delivers substantial power. It easily started my SUV and has already helped me give a jump to a stranger in a grocery store parking lot. What I love: • Strong enough to start large engines (up to 8.0L gas / 6.0L diesel) • Compact and lightweight — easy to store under a seat or in a trunk • USB-C charging is fast and modern • Feels solid and dependable, with heavy-duty clamps Bonus: Because it’s so compact, I don’t mind keeping it in the car all year — and it stays charged for months—great peace of mind, especially in cold weather. Whether it’s for your emergencies or to help someone else, this is one of the smartest things you can keep in your vehicle. Highly recommend.

Worth every penny!!!!!! It's simple to use and all of the features work perfectly after at least 20 uses. I would buy it again in a heartbeat to not have to worry about a dead battery anywhere ever again. I read an article rating different jump starter models since I didn't know the first thing about them aside from maxing out my AAA jump starts and checking what the tow company used. I chose this one because it could charge a completely dead battery and it was top rated. It seemed expensive to me at the time but I can't figure out the parasitic draw on my Acura battery and I needed the piece of mind. Best decision!

Okay, this little box is officially my hero. After trying (and failing) to jump my totally dead car battery with TWO other jumper boxes and two different vehicles, I figured my car had officially ghosted me. Enter THIS beast. One press, one solid crank, and vroom — we were back in business like nothing happened. No flashy screens or gimmicks — just a well-built, no-nonsense jumper that does the job. The clamps feel solid, the cables are longer than most, and it's super easy to use even if you're not a car person (which I’m not). Moral of the story: these jump boxes are NOT all the same. This one is the real deal. Worth every penny. Just get it — your future self stuck in a cold parking lot will thank you. VERY Highly Recommended!

What if you are stranded with a dead battery, and there is not another car in sight? Or there is another car, but no jumper cables! Wouldn't it be a life saver to have a 12v power pack designed to jump start an automobile. With its own jumper cables! That's exactly what the HPBS Jump Starter is, and more. This 12v jump starter power pack comes with jumper cables, a USB charging cable (but no power adapter), a cigarette lighter adapter (though many autos no longer come with a cigarette lighter) and a user's manual. All in a really nice, and sturdy, storage case that is only 9.5"L X 5.5" W X 4" H. The power pack also comes with two USB outputs for powering other devices. And also includes a built-in LED light with three functions (flashlight, SOS, strobe). The cigarette lighter cable enables "reverse charging" that provides charging of the car battery, in roughly 20 minutes, through the cigarette lighter port. The one disturbing issue for me revolves around temperature. In the Care and Maintanence section of the User's Manual there are two warnings: "DO NOT put the product under direct sunlight or hot areas." and, "DO NOT place the product in high temperature environment for long. The operating temperature: -22F - 140F." These are direct quotes, including the all caps emphasis. Well I live in Texas, and I am concerned about what I consider to be somewhat vague direction. In Texas, in the summer, even a garage is a hot area. And how long is too long. I do not want to risk my car, or my home when the car is in the garage. Do I need to bring the pack inside the house when I'm not driving the car. But what about when I drive somewhere with the pack in the car, but when I arrive at my destination (lets say a dinner party, or a movie, or maybe a football game) do I need to carry the power pack with me to be safe? And in something like a football game or fishing trip where I would be staying outside what is safe way to handle this power pack? Also, the power pack requires recharging every 3 to 6 months.

This jump starter is compact, light-weight, and quite easy to use. It enabled me to get my car started so I could get to my mechanic. Has a convenient storage case and fits easily under the seat.

Used twice already and worked awesome. Love how compact it is.
