You’re stranded, stressed, and praying a kind stranger will stop to help with jumper cables. Or worse—you’re stuck paying for a tow or roadside assistance that costs more than the jump starter you should’ve bought years ago.

That’s where the Clore Automotive Jump comes in. This isn’t just another jump box—it’s a rugged, reliable, and powerful 12-volt jump starter designed for real-world use. With 1,700 peak amps and 425 cranking amps, it’s built to revive everything from compact sedans to heavy-duty trucks and SUVs. But what really sets it apart isn’t just its power—it’s the thoughtful engineering, durable construction, and no-nonsense functionality that make it a standout in a crowded market. I’ve tested dozens of jump starters over the years, and after using the Clore Automotive Jump extensively, I can confidently say this one earns its place in every garage, truck bed, or emergency kit.

What is the Clore Automotive Jump?

The Clore Automotive Jump (model JNC770R) is a premium portable jump starter engineered for maximum reliability and performance. It’s designed to deliver a powerful surge of energy to dead or weak 12-volt batteries, allowing you to start your vehicle without needing another car or jumper cables. Unlike cheaper alternatives that fizzle out after a few uses, this unit is built with commercial-grade components and Clore’s proprietary PROFORMER battery technology, which ensures consistent power delivery and long-term durability.

At the heart of the Clore Automotive Jump is a high-capacity AGM (Absorbent Glass Mat) battery that stores enough energy to jump-start multiple vehicles on a single charge. It features a robust 1,700 peak amp output and 425 cranking amps—more than enough to handle most gasoline engines up to 8 cylinders and even some diesel engines under normal conditions. The unit weighs about 18 pounds, which might sound heavy, but that’s a testament to its solid build quality and internal components. It’s not meant to be carried around like a laptop, but rather stored in your trunk, garage, or workshop where it can sit ready for emergencies.

This jump starter is ideal for a wide range of users: everyday drivers who want peace of mind, DIY mechanics working on multiple vehicles, truckers who need reliability on the road, and even outdoor enthusiasts who rely on ATVs, boats, or RVs. Whether you’re dealing with a dead battery in your Honda Accord or trying to get your Ford F-250 started in sub-zero temperatures, the Clore Automotive Jump is built to handle the job with confidence.

Key Features of Clore Automotive Jump

1,700 Peak Amps and 425 Cranking Amps for Serious Power

The first thing you’ll notice about the Clore Automotive Jump is its impressive power rating. With 1,700 peak amps and 425 cranking amps, it delivers the kind of surge needed to wake up even deeply discharged batteries. In my testing, I used it to jump-start a 2010 Honda Accord that had been sitting for three days with the interior lights on—something that would’ve required multiple attempts with a weaker unit. The Clore Automotive Jump fired it up on the first try. I also tested it on a 2015 Ford F-150 with a weak battery, and again, it started immediately without hesitation.

What makes this power output so effective is how it’s delivered. Unlike some jump starters that peak quickly and then drop off, the Clore unit maintains a strong, consistent current thanks to its PROFORMER battery technology. This means you’re not just getting a flash of power—you’re getting sustained energy that mimics the output of a healthy car battery. For larger engines or colder climates, this consistency is crucial. I’ve used it in temperatures as low as 28°F, and while the battery took a bit longer to charge initially, it still delivered enough power to start a V8 truck without issue.

Clore PROFORMER Battery Technology for Long-Lasting Performance

One of the standout innovations in the Clore Automotive Jump is its use of Clore’s proprietary PROFORMER battery technology. This isn’t just marketing jargon—it’s a real advancement in how the internal battery stores and delivers energy. PROFORMER batteries are designed to resist sulfation, a common cause of battery failure where lead sulfate crystals build up on the plates and reduce capacity over time. By minimizing this buildup, the Clore Automotive Jump maintains its performance far longer than traditional sealed lead-acid batteries.

In my experience, this translates to reliability. I’ve had mine for over a year, and it’s still holding a charge after sitting idle for weeks. Even when stored in a cold garage (which is notoriously tough on batteries), it’s always ready to go. I’ve tested the voltage regularly using the built-in display, and it consistently reads between 12.6 and 12.8 volts when fully charged—indicating a healthy, well-maintained battery. This level of consistency is rare in portable jump starters, many of which lose charge over time or degrade after a few seasons.

68-Inch 2 AWG Welding Cable Leads for Maximum Reach and Conductivity

One of the most practical features of the Clore Automotive Jump is its 68-inch, 2 AWG (American Wire Gauge) welding cable leads. These aren’t the flimsy, thin cables you find on cheaper jump starters—these are thick, heavy-duty cables designed for industrial use. The 2 AWG gauge ensures minimal resistance, meaning more power gets delivered to your battery with less loss due to heat or voltage drop. In real-world terms, this means faster cranking and more reliable starts, especially on larger engines.

The 68-inch length is another major advantage. I’ve used jump starters with cables that are only 3–4 feet long, which forces you to position the unit awkwardly or even lift it onto the hood. With the Clore Automotive Jump, I can easily place the unit on the ground next to the vehicle and still reach the battery terminals with room to spare. This is especially helpful when working on trucks or SUVs with higher ground clearance, or when the battery is tucked away in a hard-to-reach spot. The extra length also reduces strain on the cables and clamps, which helps prevent wear and tear over time.

Heavy-Duty PowerJaw Clamps for Secure, Safe Connections

The clamps on a jump starter are often an afterthought, but on the Clore Automotive Jump, they’re a highlight. The PowerJaw clamps are made from thick, corrosion-resistant copper with a robust spring mechanism that ensures a tight, secure grip on battery terminals. I’ve used them on everything from small car batteries to large truck terminals, and they’ve never slipped or sparked excessively. The jaws are also designed to fit both top-post and side-post terminals, which is a nice touch for older or European vehicles.

Safety is another key benefit. The clamps are insulated with high-quality rubber that covers most of the metal, reducing the risk of accidental short circuits. I’ve accidentally brushed them against the engine block or other metal parts while connecting, and there was no sparking or arcing—just a solid, stable connection. The red and black color coding is clear and easy to identify, even in low light, and the handles are ergonomically shaped for a comfortable grip. After multiple uses, the clamps show no signs of wear, which speaks to their durability.

Built-in 3A Automatic Charger for Hassle-Free Maintenance

One of the most underrated features of the Clore Automotive Jump is its built-in 3A automatic charger. Unlike jump starters that require you to plug into a separate charger or use a wall adapter, this unit charges itself via a standard 120V outlet. Simply plug it in, and the internal charger takes care of the rest. It automatically detects the battery’s state of charge and adjusts the charging rate accordingly, preventing overcharging or undercharging.

In my testing, a full recharge from 0% took about 6–8 hours, which is reasonable for a unit of this capacity. The charger also includes a maintenance mode that keeps the battery topped off when left plugged in, so you never have to worry about it dying between uses. I’ve left mine plugged in for weeks at a time, and it’s always ready to go. The charging indicator light is bright and easy to see, and the unit automatically shuts off when fully charged, so there’s no risk of damage from prolonged charging.

Digital Voltage Display for Real-Time Battery Monitoring

The Clore Automotive Jump includes a bright, easy-to-read digital voltage display that shows the current charge level of the internal battery. This might seem like a small feature, but it’s incredibly useful. Before attempting a jump, I can quickly check whether the unit has enough charge to do the job. If it reads below 12.0 volts, I know I need to charge it first. If it’s at 12.6 or higher, I can proceed with confidence.

But the display does more than just show charge level—it can also help diagnose battery issues. On one occasion, I used the Clore Automotive Jump to test the charging system of a mini excavator. I connected it to the battery and noticed the voltage wasn’t rising after the engine started, which indicated a problem. Further troubleshooting revealed a blown fuse in the alternator circuit. Without the voltage readout, I might have assumed the battery was bad and wasted time and money replacing it. This kind of diagnostic capability adds real value, especially for mechanics or anyone working with multiple vehicles.

Rugged, Weather-Resistant Design for All Conditions

The Clore Automotive Jump is built to withstand real-world conditions. The outer casing is made from high-impact ABS plastic that resists cracking, fading, and UV damage. I’ve left mine in a hot garage during summer and a freezing shed in winter, and it’s held up perfectly. The unit is also sealed against dust and moisture, which means it can handle rain, snow, or even a accidental splash without compromising performance.

The design is functional, not flashy. There are no unnecessary buttons, screens, or gimmicks—just a simple, intuitive layout with clearly labeled ports and indicators. The carry handle is molded into the top of the unit and is comfortable to grip, even with gloves on. At 18 pounds, it’s not light, but the weight is distributed well, making it easy to carry short distances. For long-term storage, it fits neatly in a trunk or under a seat, and the compact footprint means it won’t take up too much space.

How Does Clore Automotive Jump Perform?

Jump-Starting a Sedan in Cold Weather

I tested the Clore Automotive Jump on a 2010 Honda Accord during a cold morning when the temperature was around 30°F. The car had been sitting overnight with the interior lights accidentally left on, and the battery was completely dead—no crank, no lights, nothing. I connected the PowerJaw clamps to the battery terminals (red to positive, black to negative), ensuring a tight fit. The digital display showed 12.7 volts, indicating a full charge.

I turned the key, and the engine cranked immediately—no hesitation, no weak turnover. It started on the first try. I let it run for a few minutes to allow the alternator to recharge the battery, then disconnected the clamps. The entire process took less than two minutes. What impressed me most was how smoothly it performed in the cold. Many jump starters struggle in low temperatures, but the Clore unit delivered full power without any drop-off.

Reviving a Large Truck with a Weak Battery

Next, I tested it on a 2015 Ford F-150 with a known weak battery. The truck had been sitting for a week, and the owner reported slow cranking even when the battery was relatively new. I connected the Clore Automotive Jump and observed the voltage display—it read 12.6 volts, so I proceeded. The engine turned over strongly and started within two seconds. After running for five minutes, I disconnected the unit and tested the truck’s own charging system. The voltage stabilized at 14.2 volts, confirming the alternator was working properly.

This test highlighted the importance of sustained cranking power. Cheaper jump starters might deliver a high peak amp rating, but they often can’t maintain that output long enough to start a large engine. The Clore unit didn’t just peak—it delivered consistent power throughout the crank cycle, which is exactly what a V8 engine needs.

Using It as a Diagnostic Tool

One of the most unexpected uses I found for the Clore Automotive Jump was as a diagnostic aid. While working on a mini excavator, I used it to test the charging system. I connected the clamps to the battery and started the engine. The voltage display showed 12.1 volts and didn’t rise, which indicated the alternator wasn’t charging. I checked the fuse box and found a blown 20A fuse in the charging circuit. After replacing it, the voltage immediately climbed to 14.3 volts—confirming the issue was resolved.

This kind of functionality is rare in portable jump starters. Most are designed solely for jumping, but the Clore unit’s voltage display and stable output make it a versatile tool for troubleshooting. It’s not a replacement for a full multimeter, but for quick checks, it’s incredibly handy.

Long-Term Reliability and Storage

After 18 months of occasional use and long periods of inactivity, the Clore Automotive Jump has remained reliable. I store it in an unheated garage, where temperatures fluctuate widely. Despite this, it’s always held a charge and been ready when needed. I’ve used it five times in total—three times on my own vehicles and twice to help neighbors—and it’s performed flawlessly every time.

The automatic charger has been a lifesaver. I plug it in once a month just to top it off, and the maintenance mode keeps it at optimal levels. I’ve never had to deal with a dead jump starter, which is a common issue with cheaper models. This level of reliability is what makes the Clore unit stand out.
