As mentioned above, this device is such a beast when making these jumps start. With 1700 peak Amps and 425 cranking Amps, you will be able to start any vehicle from small cars to SUVs. It also enables you to bring the light commercial battery back to life in a matter of minutes.

The best thing that the author loves about this powerful device is the excellent length of jumper clamps and cable.

Also, the cable length of 46 inches allows you to reach any vehicle’s starting point of many shapes and sizes.

If you might wonder how to charge this exceptional jump starter, there are two ways. It features a built-in charger, which you can connect to an AC outlet from your home through an extension cord. Please note that this jump starter doesn’t come with a charging cord, so you need to buy it separately if you don’t have one.

Another option to charge this battery is through a DC outlet from your car. Conveniently, this device comes with a volt male-male extension cord that will do you good. You can find the DC outlet where you plug the cigarette lighter. However, please keep your eyes on charging this device to avoid overcharging.

Thanks to the indicator lights, you can track the charging process. The lights have three colors, green, yellow, and red to indicate three statuses that the jump starter is ready to use, still needed to be charged, and needs to be recharged immediately.

The only hassle that cannot satisfy users is that the indicator lights are not straightforward. They won’t display until you hold down the small red button under the light. You might run out of power when you are not aware of it. You are also more likely to leave the jump starter overcharging as you forget to check the gauge status.

Jump-N-Carry JNC660 Pros & Cons

It’s understandable that the JNC660 unit is the top choice for professional mechanics with a bunch of benefits. However, there are some disappointing things that keep the author of this review from full satisfaction.

What We Like
  • 1700 peaking Amps, 425 cranking Amps Robust components
  • Durable and exceptional-performance battery (Jump-N-Carry performance)
  • Suitable for heavy-duty and professional tasks
  • Highly versatile for both outdoor and workspace performance
Thing to Consider
  • No on/off switch
  • The charging plug is not compatible with many types of cords

Buying & Storage

So, where to buy the Clore JNC660 at the best price?

Americans can purchase this unit from Amazon with two models JNC660 and JNC660c. The C suffix indicates that this unit is energy compliant with California and Oregon state. Apart from compliance, there’s no difference in power, performance, or design between the two models.

About storing this unit, you will have peace of mind that this jump starter uses an AGM lead-acid battery instead of a LION battery. Thanks to the excellent property of the lead-acid battery, this unit can maintain its power at 0F. This makes a huge advantage for those who live in the northern climate with harsh winter, which can kill almost any LION battery.

As this unit does not have an on/off switch, it is always on. You should prevent the clamps from touching and store the unit in the holster. It is important to prevent accidental contact between the clamp and your sloppy storage. Also, keep an eye on this unit as it cannot handle wetness very well.

Safety Precautions

As mentioned above, this unit doesn’t feature a safety switch. Thus, the power will always connect to the cables and clamps. It might be dangerous to a new user who might be careless when hooking the cables up.

Moreover, the JNC660 model should not be used by people who are unfamiliar with the charging process. It doesn’t give any alert or direction in case you fasten the cable in the wrong manner. This might result in a defective battery and even worse accidents.

Last but not least, you need to pay a lot of attention to the charging processes to prevent overcharging. The only way to do it is to keep checking the gauge status.

And if you want to have a replacement, make sure to bring it to a mechanic shop for additional advice and the right equipment.
