JNC1224

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.

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.

Missing 12v charging cable. New unit will not take a charge. Tried to wake it up by conecting it to my truck for a few minutes only to find it still wont charge, and the volt gauge is stuck on the red "test" button doesn't do anything. I will be more than happy to revisit this review if the company makes it right.

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.

Can’t say enough good things about this thing. It’s a UNIT. Bought about 4 years ago and I think I can count on one hand how many times I’ve had to even charge it. I use it on diesel trucks and heavy equipment often and it’s never let me down. I’ve had other chargers in the past that couldn’t touch this thing or only had a few minutes worth of crank time if you’re trying to get something running and then they die out. The only minor down fall I could possibly mention is it’s heavy. But if you’re an able bodied person you’ll be fine.

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.

This jumpbox is strong. It can jump a truck. It is compact and powerful

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
