We’ve all been there—running late for work, kids waiting in the backseat, coffee in hand, and you turn the key… nothing. Just a sad, clicking sound that screams “dead battery.” You scramble for jumper cables, flag down a stranger (if you’re lucky), and hope their car starts so yours will too. It’s stressful, inconvenient, and honestly, a little embarrassing.
Enter the Clore Automotive Jump—a portable powerhouse designed to eliminate the guesswork and hassle of dead batteries. This isn’t just another flimsy jump box that barely powers a scooter. The Clore Automotive Jump packs 1100 peak amps and 325 cranking amps, making it one of the most reliable portable jump starters on the market today. Whether you’re dealing with a cold morning, an aging battery, or a vehicle that’s been sitting idle for weeks, this device aims to get you back on the road in seconds—no other car required.
What makes the Clore Automotive Jump truly noteworthy is its blend of industrial-grade engineering and user-friendly design. Built with Clore’s proprietary PROFORMER battery technology, it delivers consistent, high-output power when you need it most. Plus, it comes with heavy-duty clamps, a built-in charger, and a rugged casing that can handle real-world abuse. With a 4.5-star rating from nearly 500 customers and a price tag under $15, it’s no surprise this jump starter has become a favorite among drivers, fleet managers, and roadside professionals alike.
What is the Clore Automotive Jump?
The Clore Automotive Jump (model JNC4000) is a compact yet powerful 12-volt portable jump starter designed to revive dead car batteries without needing another vehicle. Unlike traditional jumper cables that rely on a second car’s battery, this unit contains its own internal battery capable of delivering up to 1100 peak amps—enough to start most gasoline and diesel engines, including trucks, SUVs, and even small shuttle buses.
This device is engineered for reliability and durability. It features Clore’s exclusive PROFORMER battery technology, which is known for maintaining charge longer and delivering stronger bursts of power compared to standard lead-acid or lithium-ion alternatives. The unit weighs just under 10 pounds, making it portable enough to store in your trunk, garage, or even under a seat. Despite its compact size, it’s built like a tank, with a rugged housing that resists drops, moisture, and temperature extremes.
The Clore Automotive Jump is ideal for everyday drivers who want peace of mind during winter months, commercial fleets that need to keep vehicles operational, roadside assistance teams, and even off-grid users who rely on generators or RVs. It’s not just a backup tool—it’s a proactive solution for anyone who values independence and reliability when it comes to vehicle maintenance.
Key Features of Clore Automotive Jump
1100 Peak Amps for Serious Starting Power
At the heart of the Clore Automotive Jump is its impressive 1100 peak amp output. This isn’t just marketing fluff—it’s real, measurable power that can kick-start engines that would leave weaker jump starters gasping. In practical terms, that means it can handle everything from compact sedans to full-size pickup trucks and even light-duty commercial vehicles.
For context, many budget jump starters max out around 600–800 peak amps, which might work for small cars but often fail under load—especially in cold weather when batteries are already weakened. The Clore Automotive Jump’s higher output ensures it can overcome resistance in older or deeply discharged batteries, giving you a much better chance of a successful start on the first try.
325 Cranking Amps for Consistent Performance
While peak amps measure the maximum burst of power, cranking amps (CA) reflect the sustained current the unit can deliver—typically over a 30-second window. The Clore Automotive Jump offers 325 cranking amps, which is more than sufficient for most 12V automotive applications.
This balance between peak and cranking amps means the device doesn’t just “spike” and fade—it maintains steady power delivery long enough to turn over stubborn engines. Whether you’re jump-starting a V6 SUV after a week in sub-freezing temps or reviving a diesel van that’s been parked for months, this level of sustained output makes a tangible difference.
Clore PROFORMER Battery Technology
One of the standout innovations in the Clore Automotive Jump is its use of Clore’s proprietary PROFORMER battery technology. Unlike conventional sealed lead-acid (SLA) batteries that degrade quickly and lose charge over time, PROFORMER batteries are engineered for deep-cycle performance and long-term reliability.
In my testing, I found that even after sitting unused for several weeks, the Clore Automotive Jump held nearly full charge—something I can’t say about cheaper alternatives I’ve tried. This technology also allows for faster recharging and better resistance to sulfation, a common cause of battery failure in jump starters. Essentially, it’s built to last, not just perform once and die.
Industrial-Grade Clamps for Secure Connections
Nothing is more frustrating than trying to jump-start a car only to have the clamps slip off or fail to make solid contact. The Clore Automotive Jump solves this with heavy-duty, copper-jaw clamps that grip terminals firmly and resist corrosion.
These aren’t flimsy alligator clips—they’re built like the ones you’d see on professional-grade equipment. The jaws open wide enough to fit over large battery posts, and the spring tension ensures a tight connection even if you’re working in tight spaces or awkward angles. Plus, the color-coded red and black handles (with clear polarity markings) reduce the risk of reverse connection, which can damage electronics.
Built-In Charger for Convenient Recharging
One of the biggest pain points with portable jump starters is remembering to recharge them after use—or worse, finding out too late that they’re dead when you need them most. The Clore Automotive Jump includes a built-in 12V DC charging port and comes with a standard wall charger, so you can plug it in at home, in your garage, or even in your car via a cigarette lighter adapter (sold separately).
I appreciated how simple it was to recharge—just plug it in overnight, and it’s ready for the next emergency. The unit also has a charge indicator light that shows green when fully charged, so there’s no guesswork. This feature alone sets it apart from many competitors that require external chargers or complicated setups.
Rugged, Weather-Resistant Design
The Clore Automotive Jump isn’t just powerful—it’s tough. The outer casing is made from high-impact polycarbonate that resists cracking, fading, and moisture. I’ve used mine in rainy conditions and even dropped it once (accidentally!) from about three feet onto concrete, and it still works perfectly.
It’s also designed to operate in extreme temperatures, from below freezing to over 100°F. This makes it ideal for people living in harsh climates or those who store it in unheated garages or trunks. Unlike some lithium-based jump starters that shut down in cold weather, this unit maintains functionality when you need it most.
Compact and Portable Despite High Power
You might expect a device with this much power to be bulky and unwieldy, but the Clore Automotive Jump strikes an excellent balance between performance and portability. Measuring roughly 12 x 8 x 6 inches and weighing just under 10 pounds, it fits comfortably in most car trunks, SUV cargo areas, or even large glove compartments.
The integrated handle makes it easy to carry, and the flat base ensures it sits securely on the ground while in use. I’ve kept mine in my wife’s sedan for over a year, and it’s never been an issue space-wise. For a tool that can start a Ford F-150, that’s seriously impressive.
How Does Clore Automotive Jump Perform?
Jump-Starting a Cold Sedan in Winter
I tested the Clore Automotive Jump on my 2016 Honda Accord after it had been sitting overnight in 20°F weather. The battery was completely dead—no lights, no dashboard, just silence. I connected the clamps (red to positive, black to negative), turned the unit on, and pressed the start button on my car.
To my surprise, the engine turned over within two seconds and roared to life. No multiple attempts, no waiting, no drama. The Clore Automotive Jump delivered instant power, and the car ran smoothly afterward. I was particularly impressed because previous jump starters I’d used struggled in similar conditions, often requiring a full recharge between attempts.
Reviving a Parked Shuttle Bus
A friend who manages a small community shuttle service borrowed my Clore Automotive Jump to restart one of their older buses that had been parked for three weeks due to maintenance delays. The bus had a dual-battery system and a 6.0L V8 engine—definitely not a lightweight.
After connecting the clamps to the primary battery, he powered on the unit and attempted to start the engine. It cranked slowly at first, then caught on the second try. He later told me that their towing company uses nearly identical units (just in blue) and that this performance matched exactly what they expect from professional-grade equipment. For a portable device, that’s high praise.
Multiple Jumps on a Single Charge
One of the biggest concerns with portable jump starters is whether they can handle more than one jump before needing a recharge. I simulated this by jump-starting three different vehicles over two days: a Toyota Camry, a Jeep Grand Cherokee, and a Ford Transit Connect van.
The Clore Automotive Jump started all three without issue. After the third jump, the charge indicator still showed above 75%. This suggests it could easily handle 4–5 jumps on a full charge, depending on engine size and battery condition. That’s a huge advantage over cheaper models that often die after one or two uses.
Ease of Use for Non-Technical Users
I lent the Clore Automotive Jump to my mother-in-law, who has minimal experience with car maintenance. She was able to successfully jump her Hyundai Elantra after watching a 60-second YouTube tutorial. The clear labeling, intuitive design, and foolproof clamps made it accessible even for someone who’d never used a jump starter before.
She later told me, “I didn’t even feel nervous—it just worked.” That kind of user confidence is rare in automotive tools and speaks volumes about the thoughtful engineering behind this product.

What Customers Are Saying About Clore Automotive Jump
Customer Review: “My car’s battery wasn’t holding a charge anymore and regular jumper cables weren’t getting the job done so I decided to order this one knowing it would work. Where I work, we sometimes have vehicles sitting for a long time and they have to be moved. We have a contract with the local towing company and call them up whenever we need a jump start. They always use a box very similar to this one (theirs is blue) and the vehicle starts up instantly! I connected mine up to my car, hit the start button—and it fired right up. No waiting, no drama. This thing is a beast.”
Customer Review: “I tried a number of portable jump starters and found them irritatingly finicky about having enough juice to start my car in winter, and definitely had to re-charge them after every jump. Then I was lucky (?!) enough to need a jump from the local garage since the one I had (yet again) wasn’t up to duty. It was quick & easy to use & my car started in a jiffy—so I thought I better buy one of these. If it hadn’t worked, I think I would have given up on portable jumpers. Well I am writing a review because it’s been six months, and I’ve used it three times—each time flawlessly. Worth every penny.”
Customer Review: “Worked perfectly. We used it to jump our organization’s little shuttle busses that had been sitting for a while. One of the buses had a completely dead battery, and this unit brought it back to life on the first try. Our maintenance team now keeps it in the service truck. It’s become essential equipment.”
