Jump-N-Carry JNC1224 3400/1700 Peak Amp 12/24V Jump Starter

This jump box is a little bulky and heavy but, it jumped my completely dead F350 diesel in 0 degree F weather. It charges pretty quick and I’m positive that it will start pretty much anything you throw at it. The cables aren’t super long but there is enough to get you where you need to go.

I purchased two of these over the past 4 months for two different locations. This thing is a beast! It is heavy, first and foremost. This is not a toy. It is not a small lithium ion starter you buy from HF. This jump box is well built, and strong and will start just about anything! I literally started a Cat 977 with two dead batteries and the machine had not been run in years. This jump box did not even flinch! I have started many trucks, from F250's up the tandem dump trucks without any problems. You get what you pay for and this is a good value for the month. It is simple, no frills, no modern electronics but it does the job and does it very well. Know what you are doing when you use it because there is a lot of power coming from this box.

These things are great. We have 2 of them, we mainly jump dead dump trailers with them. So it lifts 14k pounds with a dead trailer battery. Pretty impressive.

Stopped working after 2 months – can’t start my truck anymore! I bought the Clore Automotive JNC1224 jump starter in December 2024. At first, it worked great — strong power, easy to use, and seemed reliable. But after only 2 months of use, it completely stopped charging. Now it won’t hold any charge at all and is completely useless when I try to jump-start my truck. I rely on this tool for work, and it let me down at a critical time. This is a $380+ product — I expected much better durability. Pros (while it worked): – Strong initial power – Easy to carry and use Cons: – Stopped working after 2 months – Won’t charge or jump-start anymore

Been using this product for our shops for years. Works great, but just a little heavy.

Should have bought this years ago! I bought the 12/24 just jump started a completely dead 980c cat loader spun it over like I just put two new batteries in it very impressive! It is a little heavy but you can tell that’s because it’s built really well and should last longer than those smaller light weight ones, if you own heavy equipment or big trucks don’t hesitate you won’t regret it.

This is an excellent heavy duty jump box. I have not come across a single car that it won't effortlessly start. I work at a junk yard and use it to jump cars with dead batteries and even no batteries all the time. Starts anything from a little Honda all the way to big diesel truck. We also use it to jump a CAT 950G Front end Loader that is 24V. It jumps that without hesitation as well. I can also leave it plugged in overnight and use it to jump cars all day long. It will easily start completely dead cars without hesitation all day on a single charge. The other big reason we got this is because it actually has a smart charger on it. You can leave it plugged in and it maintains the battery. I've had one of these for over 5 years and have jump started hundreds of vehicles and it worked just as good being 5 years old as it did day 1. It finally gave out after one of my friends hooked it up to his car backwards and left it on with the car running for about an hour. I probably could of just replaced the batteries but I ended up just buying a new unit since the old one help up so well. I keep the old one around as a backup as it still works as a last resort. My only complaint is the weight of the unit, but for what we use it for, we need something that last all day and can start many cars and some of our heavy equipment.

Worth every penny I should of bought a long time ago saves so much time

Works great on my 24v equipment

I work for a mobile mechanic for a landscaping & construction Company, we keep this unit in our service truck and we use it all the time from company vehicles all the way to our largest heavy equipment. this tool is a must have!

excellent product will boost anything

I would give this zero stars if I could. It quit working after 1 use. The company would not answer calls or respond to email. Such a bummer for the cost.

Powerful rig cable on the 12 to 24 is short
