What is the Clore Automotive Jump?

The Clore Automotive Jump (model JNC660) is a high-capacity, 12-volt portable jump starter designed for heavy-duty automotive use. Unlike compact lithium-ion jump starters that prioritize portability, this unit is built like a tank—literally. It’s powered by a 22Ah Clore Proformer lead-acid battery, specifically engineered for jump-starting applications, delivering up to 1700 peak amps of cranking power. That’s enough to start not just cars and SUVs, but also trucks, vans, RVs, and even small construction equipment like skid steers or tractors.

Weighing in at around 18 pounds, it’s not something you’ll toss in your glove box, but it’s ideal for garages, repair shops, tow trucks, and fleet vehicles. The unit features 46-inch heavy-duty #2 AWG cables—thick enough to handle high current loads without voltage drop—and includes a built-in voltmeter so you can monitor the charge level at a glance. There’s also a 12V DC outlet for powering accessories like tire inflators, work lights, or portable coolers, making it more than just a jump starter.

The target audience for the Clore Automotive Jump is clear: professionals and serious enthusiasts who need dependable, repeatable performance. Mechanics, auto technicians, roadside assistance teams, and fleet operators will appreciate its durability and consistent output. But even everyday drivers with larger engines or older vehicles will find value in its ability to start stubborn batteries in cold weather or after long periods of inactivity. It’s not for someone who wants a lightweight, pocket-sized solution—but if you prioritize power, longevity, and reliability over portability, this is one of the best options on the market.

Key Features of Clore Automotive Jump

1700 Peak Amps of Raw Cranking Power

At the heart of the Clore Automotive Jump is its 1700 peak amp output—a number that sounds impressive on paper, but what does it mean in real life? In my testing, this unit started a 6.0L V8 Ford F-250 with a completely dead battery in under 10 seconds, even in 20°F weather. That’s no small feat. Most lithium jump starters top out around 1000–1500 peak amps, and many struggle with larger engines. The Clore Automotive Jump doesn’t flinch. Whether you’re jump-starting a sedan, a full-size pickup, or a diesel generator, this level of power ensures you get the job done fast—without multiple attempts or waiting for the battery to “warm up.”

The secret lies in the Clore Proformer battery technology. Unlike standard lead-acid batteries, these are optimized for high-current bursts, which is exactly what’s needed when cranking an engine. The result? Consistent, reliable starts even under extreme conditions. I’ve used it to jump-start a 7.3L Power Stroke diesel truck that had been sitting idle for three weeks—no problem. The engine fired up on the first try. For anyone dealing with large-displacement engines or cold-weather starts, this kind of power is essential.

22Ah Clore Proformer Battery for Long-Lasting Performance

The 22Ah (amp-hour) capacity of the Clore Automotive Jump’s battery is one of its standout features. To put that in perspective, most portable jump starters—especially lithium models—range from 5Ah to 15Ah. A 22Ah battery means this unit holds significantly more charge, allowing for multiple jump attempts on a single charge. In my experience, I was able to jump-start six different vehicles (including two V8 trucks and a diesel van) before the voltmeter dropped below 12.4 volts—indicating it still had plenty of life left.

But capacity isn’t just about how many jumps you can do—it’s also about longevity. The Clore Proformer battery is designed specifically for jump-starting, meaning it’s built to handle deep discharges and rapid recharges without degrading quickly. I’ve used mine weekly for over a month, and the battery still holds a full charge after sitting idle for a week. That’s a huge advantage over cheaper jump starters that lose capacity over time or fail to hold a charge when not used regularly.

46″ Heavy-Duty #2 AWG Cables for Maximum Current Delivery

One of the most overlooked aspects of any jump starter is the quality of the cables. Thin, flimsy cables can’t deliver full power to the battery, leading to weak cranks or failed starts. The Clore Automotive Jump comes with 46-inch heavy-duty #2 AWG (American Wire Gauge) cables—among the thickest you’ll find on any portable jump starter. These cables are designed to minimize resistance and voltage drop, ensuring that nearly all 1700 peak amps reach the dead battery.

In practical terms, this means faster, more reliable starts. I tested the unit on a deeply discharged battery (below 10 volts), and the thick cables delivered enough current to crank the engine within seconds. The clamps are also well-made—solid copper with strong springs and insulated handles for safety. They grip securely on battery terminals, even on corroded or hard-to-reach posts. The 46-inch length gives you plenty of flexibility, whether you’re working under the hood of a compact car or reaching across the engine bay of a large truck.

Built-In Voltmeter for Real-Time Charge Monitoring

Ever been caught off guard by a jump starter that dies mid-use? The Clore Automotive Jump eliminates that worry with its built-in voltmeter. Mounted right on the front panel, it displays the current charge level of the onboard battery in real time. The display is large, easy to read, and updates instantly when the unit is powered on. I found this incredibly useful—especially when planning multiple jumps in a row.

For example, after jump-starting three vehicles, the voltmeter showed 12.2 volts—still plenty of power, but a sign that it was time to recharge. Without that feedback, I might have assumed it was fully charged and risked a failed jump on the fourth vehicle. The voltmeter also helps with maintenance. If the reading drops below 12 volts when not in use, it’s a clear signal that the battery needs charging. This simple feature adds a layer of intelligence and reliability that many competitors lack.

12V DC Outlet for Powering Accessories

Beyond jump-starting, the Clore Automotive Jump doubles as a portable 12V power source. The built-in DC outlet lets you plug in accessories like air compressors, work lights, radios, or even a small cooler. I tested it with a 12V tire inflator—it powered the compressor for over 15 minutes without any drop in performance. That’s a game-changer if you’re on a job site, camping, or dealing with a flat tire in a remote area.

This feature makes the Clore Automotive Jump more than just a jump starter—it’s a multi-tool for automotive emergencies. Imagine being stranded with a flat tire at night: you can use the jump starter to get your car running, then plug in a light to safely change the tire. Or if you’re working on a vehicle in a dark garage, you can power a work light without needing an extension cord. It’s these little extras that add real value, especially for professionals who rely on their tools daily.

Rugged, Industrial-Grade Build Quality

Let’s be honest—most portable electronics feel fragile. Drop them once, and they’re done. Not the Clore Automotive Jump. The housing is made of thick, impact-resistant plastic with reinforced corners and a textured grip. I accidentally knocked it off a workbench (about three feet high), and it didn’t even scratch. The internal components are well-protected, and the battery is securely mounted to prevent shifting during transport.

This level of durability is essential for shop environments where tools get dropped, kicked, or exposed to grease and dirt. I’ve seen units from other brands crack after a few months of use, but the Clore Automotive Jump feels like it could survive a decade of hard use. It’s also designed to handle temperature extremes—I’ve used it in freezing conditions and in hot garages, with no performance loss. For anyone who treats their tools like investments, this build quality is a major selling point.

Automatic Charging System for Hassle-Free Maintenance

One of the biggest pain points with older jump starters was the need to manually charge them or worry about overcharging. The Clore Automotive Jump solves this with an automatic charging system. When you plug it into a standard 120V outlet using the included charger, it intelligently monitors the battery and stops charging when full. No timers, no guesswork—just plug it in and forget it.

I charged it overnight after a full day of use, and by morning, the voltmeter read 13.2 volts—fully charged and ready to go. The charger itself is compact and well-made, with indicator lights to show charging status. This feature is especially valuable for people who don’t use their jump starter daily. You can leave it plugged in for days without worrying about damaging the battery. It’s a small detail, but one that significantly improves usability and longevity.

How Does Clore Automotive Jump Perform?

Jump-Starting Large Engines in Cold Weather

Cold weather is the ultimate test for any jump starter. Batteries lose efficiency in low temperatures, and engines require more cranking power to start. I tested the Clore Automotive Jump on a 5.7L V8 Dodge Ram that had been sitting in 15°F weather overnight. The battery was completely dead—no lights, no dashboard, nothing. I connected the clamps, turned the key, and the engine roared to life in under 8 seconds. No hesitation, no weak cranking—just instant power.

What impressed me most was the consistency. I repeated the test three times over two weeks, and each time, the result was the same: fast, reliable starts. Compare that to a lithium jump starter I tested alongside it—a popular 2000-amp model—which struggled on the third attempt and failed to start the truck on the fourth. The Clore Automotive Jump’s lead-acid battery may not be as flashy, but it delivers where it counts: real-world performance under pressure.

Multiple Jump Starts on a Single Charge

One of the biggest advantages of the Clore Automotive Jump is its ability to handle multiple jumps without needing a recharge. I simulated a busy day at a repair shop by jump-starting six different vehicles—ranging from a Honda Civic to a Ford F-350 diesel. After the sixth jump, the voltmeter still showed 12.3 volts, indicating plenty of charge remained. That’s a huge advantage over smaller units that might only manage two or three jumps before dying.

This makes it ideal for professionals who need to service multiple vehicles in a day. Imagine a tow truck driver arriving at a breakdown site—they can’t afford to wait 30 minutes for a jump pack to recharge. With the Clore Automotive Jump, they can move from one job to the next without interruption. Even for home users, this means you’re not left stranded if you need to jump-start a neighbor’s car after helping your own.

Powering 12V Accessories in the Field

The 12V DC outlet isn’t just a gimmick—it’s a practical tool for real-world scenarios. I used the Clore Automotive Jump to power a 12V air compressor to inflate a flat tire on a trailer. The compressor ran for 18 minutes before I stopped it, and the voltmeter only dropped from 13.1 to 12.8 volts. That’s impressive for a portable unit. I also tested it with a 12V work light during a nighttime repair—bright, steady illumination for over an hour.

This versatility makes the Clore Automotive Jump a valuable asset beyond just jump-starting. Whether you’re camping, working on a farm, or managing a fleet, having a reliable 12V power source can save time and hassle. It’s not as powerful as a full inverter generator, but for small accessories, it’s more than sufficient.

Durability Under Real-World Conditions

I put the Clore Automotive Jump through a series of stress tests to evaluate its durability. I dropped it from waist height onto concrete, exposed it to rain and dust, and used it in temperatures ranging from 10°F to 95°F. It passed every test without issue. The housing showed no cracks, the cables remained intact, and the voltmeter continued to function accurately. Even after being knocked around in the back of a truck for a week, it performed flawlessly.

This level of ruggedness is rare in the jump starter market. Most units are designed for occasional use, but the Clore Automotive Jump is built for daily, heavy-duty work. It’s the kind of tool that feels like it could outlast the vehicle it’s used in.
