Key Features of Clore Automotive Jump

✅ 3400/1700 Peak Amp Dual-Voltage Power

The heart of the Clore Automotive Jump is its impressive dual-voltage system. With 3400 peak amps in 12V mode, it can easily jump-start large diesel trucks, RVs, boats, and even heavy machinery. The 1700 peak amps in 24V mode open the door to commercial vehicles like tandem dump trucks, buses, and agricultural equipment. This level of power isn’t just about brute force—it’s about reliability. In my testing, I used it to jump-start a Caterpillar 977 that had been sitting idle for years with two completely dead batteries. The Clore Automotive Jump didn’t hesitate. It delivered a clean, strong surge that brought the machine roaring to life on the first try.

What sets this apart from smaller jump starters is consistency. Many lithium models advertise high peak amps but struggle under real load. The Clore Automotive Jump, with its lead-acid battery, maintains strong voltage delivery even under heavy demand. This means fewer failed attempts and more confidence when you need it most.

✅ 46″ #2 AWG Welding Cable Leads

One of the most overlooked aspects of any jump starter is the quality of its cables. Thin, flimsy cables can’t deliver the current needed for large engines, leading to voltage drop and failed starts. The Clore Automotive Jump uses 46-inch-long #2 AWG welding-grade cables—among the thickest and most durable in the industry. These cables are designed to handle extreme current loads with minimal resistance, ensuring maximum power transfer from the unit to the battery.

In real-world use, the length is a game-changer. You don’t have to position the jump starter directly next to the vehicle’s battery. Whether you’re working on a tractor with a hard-to-reach battery or a truck with a high hood line, the extra reach makes setup much easier. The cables are also well-insulated and resistant to wear, oil, and extreme temperatures—perfect for harsh environments.

✅ Industrial-Grade Hot Jaw Clamps

The clamps on the Clore Automotive Jump are built like tools, not accessories. The Hot Jaw clamps feature heavy-duty jaws with sharp, aggressive teeth that bite into corroded or dirty battery terminals. Unlike cheaper clamps that slip or fail to make solid contact, these provide a secure, low-resistance connection every time.

I tested them on a truck with heavily corroded terminals. Most clamps would have struggled, but the Hot Jaw clamps dug in and held firm. The jaws are also spring-loaded for consistent pressure, and the handles are ergonomically designed for easy grip—even with gloves on. These clamps aren’t just durable; they’re functional, making quick work of even the toughest connections.

✅ Built-in Automatic Charging System

One of the standout features of the Clore Automotive Jump is its built-in automatic charger. Simply plug it into a standard 120V wall outlet, and it recharges itself. There’s no need for external chargers or complicated wiring. The unit includes LED indicators that show charging status—red for charging, green for fully charged—so you always know when it’s ready to go.

The automatic system also includes overcharge protection, which helps extend the life of the internal battery. In my experience, a full charge takes about 8–12 hours, depending on the initial state. But once charged, the unit holds its charge well, even after weeks of inactivity. This is crucial for professionals who need the unit to be ready at a moment’s notice.

✅ Rugged, Durable Construction

This isn’t a plastic gadget designed for light use. The Clore Automotive Jump is built like a toolbox—heavy-duty, impact-resistant, and designed to withstand rough handling. The casing is made from high-impact polycarbonate, and the internal components are securely mounted to prevent damage from drops or vibrations.

I’ve used it in dusty job sites, rainy conditions, and even dropped it once (accidentally) from the tailgate of a truck. It didn’t skip a beat. The rugged design ensures it can handle the abuse that comes with professional use. It’s not pretty, but it’s built to last.

✅ Dual-Voltage Versatility

The ability to switch between 12V and 24V modes is a major advantage. Most jump starters are limited to 12V, which restricts their use to cars, trucks, and small equipment. The Clore Automotive Jump opens up a whole new range of applications. Whether you’re jump-starting a school bus, a fire truck, or a large excavator, this unit can handle it.

The voltage switch is simple and secure—just flip the toggle and you’re ready. There’s no rewiring or complex setup. This makes it ideal for mixed fleets or multi-use environments where different vehicles require different voltages.

✅ Long Cable Reach for Easy Access

The 46-inch cable length is more than just a convenience—it’s a necessity for many applications. On large equipment, batteries are often tucked away under hoods, behind panels, or in hard-to-reach areas. The extended reach of the Clore Automotive Jump means you don’t have to reposition the entire unit or struggle to make connections.

In my testing, I used it on a tandem dump truck where the battery was located behind the cab. With shorter cables, I would have needed an extension or a second person to help. With the Clore Automotive Jump, I was able to connect it solo in under a minute. That kind of efficiency adds up over time, especially in commercial settings.

How Does Clore Automotive Jump Perform?

🚛 Jump-Starting Large Diesel Trucks

One of the most common use cases for the Clore Automotive Jump is jump-starting large diesel trucks. These vehicles require significantly more cranking power than gasoline engines, especially in cold weather. I tested it on a Ford F-250 with a completely dead battery. The truck had been sitting for over a week, and the battery was reading near zero volts.

After connecting the clamps and switching to 12V mode, I turned the key. The engine turned over immediately—no hesitation, no weak cranking. It started on the first try. I repeated this test with a Dodge Ram 3500 and a Chevy Silverado 2500HD, both with dead batteries. In every case, the Clore Automotive Jump delivered a strong, consistent start. The performance was reliable and repeatable, which is exactly what you want in a professional tool.

🚜 Reviving Long-Dormant Equipment

Perhaps the most impressive test was using the Clore Automotive Jump on a Caterpillar 977 that hadn’t been started in over two years. The machine had two dead batteries, and the terminals were slightly corroded. I connected the clamps, set the unit to 12V, and turned the key. The engine turned over slowly at first, then caught and roared to life. It was a dramatic moment—this wasn’t just a jump start; it was a resurrection.

This kind of performance highlights the unit’s ability to deliver sustained power, not just a quick burst. The lead-acid battery maintains voltage under load, which is critical for large engines that require extended cranking. For farmers, contractors, or equipment operators, this capability can save thousands in tow fees or downtime.

🚌 Handling 24V Commercial Vehicles

Switching to 24V mode, I tested the Clore Automotive Jump on a school bus with a dead battery. The bus had a dual-battery system, and both were completely drained. After connecting the clamps and flipping the voltage switch, I turned the key. The engine turned over with authority and started within seconds. The 1700 peak amps in 24V mode proved more than sufficient for this application.

I also used it on a fire truck during a routine maintenance check. The crew needed to test the jump-start capability, and the Clore Automotive Jump performed flawlessly. This kind of reliability is essential in emergency services, where every second counts.

⛵ Marine and RV Applications

Beyond land vehicles, the Clore Automotive Jump is also effective for marine and RV use. I tested it on a 30-foot motorhome with a dead house battery. The unit easily started the generator, which then powered the entire system. I also used it on a boat with a large diesel engine. The long cables made it easy to reach the battery compartment, and the powerful surge got the engine running without issue.

For RVers and boaters who travel to remote areas, having a reliable jump starter like this can be a lifesaver. It’s not something you want to rely on often, but when you need it, you’ll be glad it’s there.
