JNC345 Jump-N-Carry 3000A 12 Volt Lithium Jump Starter for up to 10.0-Liter Gasoline and 10.0-Liter Diesel Engines

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..

Excellent product. Have had it for over a year and used it three times for myself and friends. Reliable and easy to use and versatile.

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!

I have used this product several times over the last year. It worked as intended every time except once, when the battery involved was severely depleted. The one thing that stops me buying this product again is that the jaws of the cables are quite small and this can make it difficult to get a good connection to the battery terminals. I've always managed to make the connection after some effort, and maybe you'll be much better than me, but given that having to jump start a battery can occur in relatively stressful circumstances, you just want everything to be as easy as possible, and these jaws don't quite fit that billing.

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!

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.

The jump-n-carry is a must have! So much easier than standard jumper cables. The device holds a charge for a long time and is compact enough for car storage. I highly recommend!
