The Powerful JNC660 Jump Starter: 1700 Peak Amps Reviewed

The Jump N Carry JNC660 is a highly rated jump starter on the market in 2023. Its impressive capabilities make it a standout option in the industry, making it a great choice to review and present.

In previous reviews, we have covered mini jump starters that also function as power banks, allowing for the charging of various devices and gadgets. However, the JNC660 differs in that it is specialized solely for jumpstarting.

While some may prefer a multifunctional device, the JNC660’s specialized focus on jumpstarting makes it an excellent option for those in need of a reliable and powerful jump starter. Additionally, it also has a 12V outlet for additional functionality.

Jump-N-Carry JNC660 – Unpacking

If you have read some of our previous reviews you would notice that we were emphasizing the size of the mini jump starters we reviewed. All of them were literary pocket-sized devices based on lithium-ion batteries.

This JNC660 Jump-N-Carry jump starter is not the such device. This portable jump starter definitely is bigger and heavier but you have to understand that this one is way much more powerful and stronger than all of them. It is a size of a suitcase and actually, it looks just like that.

A blue-colored device with jumper clamps built-in and nicely wrapped around this device looks pretty much nice and handy despite its size.

On the front side of JNC660 you will notice a few things:

• Voltmeter (allows you to check the status of the battery inside this portable jump starter by pressing the red button just under it)
• 12V power outlet (can power a variety of accessories. Also includes automatic circuit protection to prevent overloads)
• Status lights
• Built-in charger (features completely automatic charging which allows the unit to be in always ready state)
• Jumper clamps (these 42 inches long and super quality clamps definitely will deliver power to 12V battery without fear to be melted or in any way damaged)
• Weight 18 lbs
• Dimensions: 3 x 14.1 x 5.1 inches

An important feature of this portable jump starter is a fully replicable Clore PERFORMER battery. These batteries are designed for maximum power density and durability, which results in exceptional cranking power, extended cranking duration, and long service life.

JNC660 Jump Starter for diesel engines and heavy-duty trucks

It is well-known fact that larger diesel engines require more cranking power to start. As mentioned earlier on this post this portable jump starter is a very powerful device and can be used to jump-start diesel 8L engines or heavy-duty trucks. Sometimes even smaller, less powerful cars and engines require a high boost of Amps before they can start especially during cold winter days.

With Jump N Carry JNC660 you will NOT have a drained battery problem again that is for sure. With 1700 peak Amps and 425 Cranking Amps you can start SUV or any big diesel engine with no problem as we tested it on our diesel SUV and didn’t have any problem even though our 12V battery was completely drained.

All you need to do is to check if your portable jump starter is fully charged in order to perform full power to the battery, connect the clamps on the correct way (check this article if you are not sure how to do it), and when all is ready to go turn your key to start the car. Voila! That’s it. Simple and easy.

A 1700 peak amp is enough to start a dead cow if you ask me so I am sure you will not have a problem starting whatever vehicle you own even on cold winter days.

What I liked most is the length of the jumper clamps. Ah man what a relief when you can manipulate with those and it makes it much easier to connect to the battery. Also, the quality is very good I have to say but I guess it has to be because with such power they would melt easily which is dangerous as well.

After you start the engine (I don’t doubt you will) just carefully detach the clamps and let the engine fill the car battery.

Another thing that can be done with JNC660 is simply to charge a dead battery. Simply connect it to a drained battery and let it charge it (needs approximately 2h to charge a fully drained 12V battery.

Safety precautions

Jump N Carry JNC660 is a well-made jump starter. Hard plastic housing and quality jumper clamps make this device safe to use. This is important when you use it of course, but also a great thing about this jump starter is that you can leave it plugged in while charging and it won’t get damaged as it has a voltage regulator built in. Nevertheless, it is even recommended to keep it constantly charged not because you need it but because of the battery’s health.

The battery inside is replaceable as well as the jumper clamps and that is a great thing. These features make this jump starter even more confident and it is no wonder why it is so well-rated and popular among customers of all profiles.

What do customers say about JNC660 1700 Peak Amp 12-Volt Jump Starter?

The main reason we picked this portable jump starter to review is because of his remarkable reputation. We witnessed his great power and quality made. It started with 8l diesel which means it can start almost any vehicle you can attach it to.

In this part of the review, we would like to share some of this feedback.

“Had a dead battery in my truck kept the JNC660 in the cab and used it 9 times to start the truck without recharging, this works great.”

“I drive an auto transport truck. I move cars with dead batteries often. This jump pack has never failed me and has plenty of power. Even starts diesel pickups with ease.”

“I’ve owned one of these for more than 10 years and it still works flawlessly. I keep it in the trunk and charge it very infrequently. Yet it has always been ready to go. As a result of my personal experience, I bought three Jump-N-Carries for staff/fleet at the office.”

We didn’t miss to mention the bad experiences which were, to be honest very rare:

“Nice – however first one was dead within a week but the seller replaced immediately and the new one has been efficient and solid. Nice product.”

“I plugged it in to charge and the amber led that is supposed to be lit does not indicate it is charging. The Green LED does not show it is fully charged either.”

“A clamp broke after a short period of use”

An important thing to mention is that most of the customers who reported problems solved the issue by contacting the manufacturer (Clore Automotive) and their broken or non-functioning jump starter was replaced with a new one.

Conclusion

We were not left disappointed using JNC660 that is for sure. It did its job pretty well. Jump started an 8l diesel truck with ease. We were satisfied with almost every feature of this portable jump starter. The power is remarkable (425 cranking amps and 1700 peak amps) and it is quality made.

Compared to mini jump starters it has some cons. For example, it is much bigger and heavier so it has to go into the trunk and the glove box is too small for this big fellow. It has no USB outlet not a flashlight like most of the mini jump starters. This fact makes it specialized for 12V accessories and a function as a jump starter. This is not so bad, in fact, this means it is specialized to be a jump starter and it does its function pretty well.

Keep it fully charged and he will not fail you!
