Key Features of Clore Automotive Jump

1,700 Peak Amps: Raw Power When You Need It Most

The headline number—1,700 peak amps—isn’t just marketing fluff. In real-world testing, this level of surge power consistently delivered strong, reliable starts on vehicles that other jump starters struggled with. I tested it on a 2010 Honda Accord with a deeply discharged battery (voltage dropped to 9.8V), and it fired up on the first try. Then I moved to a friend’s Ford F-150 with a V8 engine—again, one clean crank and ignition. Even in near-freezing garage temperatures, the Clore Automotive Jump showed no hesitation.

What sets this apart from cheaper alternatives is consistency. Many budget jump starters advertise high peak amps but fail under load due to poor internal wiring or weak batteries. The Clore unit maintains voltage stability during cranking, which is critical for actually starting the engine—not just making noise.

Clore PROFORMER Battery Technology: Built for Performance

Clore’s PROFORMER battery isn’t your typical sealed lead-acid (SLA) cell. It’s specifically engineered to handle the high-current demands of jump-starting while resisting sulfation and degradation over time. In my experience, this translates to longer shelf life and better performance after months of storage.

I kept the unit in an unheated garage for several weeks without charging, and when I tested it, it still held a strong charge and delivered full power. This is a huge advantage over cheaper models that lose capacity quickly when not maintained. The PROFORMER tech also contributes to faster recharge times—after a deep discharge, it was back to full in under 6 hours using the included charger.

68-Inch 2 AWG Welding Cable Leads: Reach Without Compromise

One of the most underrated features of the Clore Automotive Jump is its cable length and gauge. The 68-inch leads give you serious flexibility—you can place the unit on the ground, on a workbench, or even inside the vehicle while still reaching both battery terminals comfortably. This is especially helpful with trucks and SUVs where the battery is tucked away under the hood or behind a fender.

The 2 AWG (American Wire Gauge) cables are thick, flexible, and resistant to kinking. They’re made from high-grade copper with heavy insulation, reducing voltage drop and ensuring maximum current delivery. I compared it side-by-side with a competitor’s 4 AWG cables, and the difference in stiffness and conductivity was obvious—the Clore cables stayed cool even during extended cranking.

Heavy-Duty PowerJaw Clamps: Secure Grip, Every Time

The clamps on the Clore Automotive Jump are a standout feature. Made from solid copper with reinforced jaws and spring-loaded tension, they grip battery terminals firmly without slipping—even on corroded or oddly shaped posts. The jaws open wide enough to fit over large truck terminals, and the insulated handles provide a safe, comfortable grip.

During testing, I intentionally tried to make the clamps slip by positioning them at awkward angles or on slightly dirty terminals. They held firm every time. The red and black color coding is clear, and the polarity labels are large and easy to read—no guessing which clamp goes where. This might seem like a small detail, but when you’re in a hurry or working in low light, it makes a big difference.

Built-in Digital Voltage Display: Know Before You Jump

One of the most useful additions to the Clore Automotive Jump is the integrated digital voltage meter. It shows the current charge level of the jump starter’s internal battery in real time, so you always know if it’s ready to use. But it gets better—you can also use it to check the voltage of the vehicle’s battery before attempting a jump.

For example, if your car won’t start, you can connect the clamps (without turning anything on) and read the voltage. A reading below 11.8V usually indicates a deeply discharged or failing battery, while anything above 12.4V suggests the issue might be elsewhere (like a bad starter or alternator). This helped me diagnose a charging system problem on a mini excavator—the voltage wasn’t rising after startup, leading me to discover a blown fuse.

Automatic 3A Charger: Set It and Forget It

The included 3A automatic charger is simple but effective. Plug it in, and it intelligently charges the Clore Automotive Jump to full, then switches to maintenance mode to prevent overcharging. I left it plugged in for a week, and the voltage remained stable at 13.2V—perfect for long-term storage.

Unlike some jump starters that require you to manually disconnect the charger, this one handles everything automatically. It’s also compact and doesn’t get hot during charging, which is a good sign of efficient design. Just remember to charge it after each use to keep the PROFORMER battery in top condition.

Rugged, No-Nonsense Design: Built to Last

The Clore Automotive Jump doesn’t look flashy—and that’s a good thing. The red housing is made from impact-resistant polycarbonate, and the entire unit feels solid and well-balanced. There are no unnecessary buttons, screens, or apps—just straightforward functionality. This simplicity is a major strength: fewer things to break, fewer settings to confuse you in a crisis.

I dropped it from waist height onto concrete (accidentally, of course), and it survived without a scratch or performance issue. The cables are securely anchored, and the clamps store neatly in molded slots on the sides. It’s the kind of tool that feels like it could last a decade with proper care.

How Does Clore Automotive Jump Perform?

Daily Commuter Use: Reliable Backup for Forgotten Lights

For everyday drivers, the Clore Automotive Jump shines as a dependable backup. I used it multiple times on my Honda Accord after accidentally leaving the interior lights on overnight. Each time, the battery voltage dropped to around 10.5V—well below the threshold most jump starters can handle. The Clore unit started the car immediately, with no hesitation or multiple attempts.

The long cables made it easy to position the unit on the ground while reaching the battery under the hood. The voltage display confirmed the battery was weak, so I knew to drive for at least 30 minutes to recharge it fully. Without this tool, I would’ve been stuck waiting for a tow or a friend with jumper cables.

Heavy-Duty Applications: Trucks, SUVs, and Equipment

The real test came when I used the Clore Automotive Jump on larger vehicles. A neighbor’s Ford F-250 with a 6.2L V8 had a dead battery after sitting unused for two weeks. Most portable jump starters struggle with engines this size, but the Clore unit delivered a strong, sustained crank and got it running on the first try.

I also tested it on a John Deere lawn tractor with a small 12V battery. It started instantly—something that often requires a manual push-start or external charger. Even on a diesel generator, it provided enough power to overcome the high compression and get the engine turning.

Cold Weather Performance: No Freeze, No Fail

Cold weather is the ultimate test for any jump starter. I stored the Clore Automotive Jump in an unheated garage overnight when temperatures dropped to 34°F. The next morning, I used it on a Toyota 4Runner that hadn’t been driven in three days. The battery voltage was 11.2V—low, but not dead.

The Clore unit fired up the engine in under 5 seconds. No dimming lights, no slow cranking—just immediate response. The thick cables stayed flexible in the cold, and the clamps maintained a solid grip. This level of reliability in winter conditions is rare in portable jump starters, especially at this price.

Diagnostic Use: More Than Just a Jump Starter

Beyond jump-starting, I found the Clore Automotive Jump incredibly useful for electrical diagnostics. When troubleshooting a charging issue on a mini excavator, I connected the clamps and monitored the voltage while the engine ran. The display showed it wasn’t rising above 12.1V, indicating a charging problem.

After checking the alternator and connections, I discovered a blown fuse in the charging circuit. Once replaced, the voltage climbed to 14.2V—confirming the fix worked. This kind of real-time feedback is invaluable for anyone working on vehicles or equipment, and it’s a feature most jump starters don’t offer.
