What Is the Everstart Maxx Jump Starter Charging Cord?

The Everstart Maxx jump starter charging cord is the essential accessory that connects your Everstart Maxx portable jump starter to a power source—typically a standard 120V wall outlet or, in some models, a 12V car cigarette lighter socket. This cord delivers the electrical current needed to recharge the internal lithium-ion battery inside your jump starter, ensuring it has enough power to jump-start your vehicle when needed.

Design and Compatibility

Most Everstart Maxx jump starters come with a dedicated charging cord that’s specifically designed for that model. The cord usually features a standard AC plug on one end and a proprietary connector on the other that fits snugly into the charging port on the jump starter. Some newer models may include a dual-input option, allowing you to charge via USB-C or a car adapter, but the primary method remains the wall outlet charging cord.

It’s important to note that not all Everstart Maxx models use the same charging cord. For example, the Everstart Maxx 1200A and the 1750A may have slightly different connectors or voltage requirements. Always check your user manual or the label on your jump starter to confirm compatibility. Using the wrong cord—or a generic replacement—can result in slow charging, overheating, or even damage to the device.

Why the Charging Cord Matters

You might think, “It’s just a cord—how important can it be?” But here’s the truth: a faulty or incompatible charging cord can leave you stranded just as easily as a dead jump starter. I learned this the hard way when I tried using a generic USB cable to charge my jump starter. It took over 12 hours to reach 50% charge, and the device overheated twice. The manufacturer later confirmed that the cord wasn’t delivering the correct voltage, which could have damaged the battery over time.

The Everstart Maxx jump starter charging cord is engineered to deliver the right amount of power efficiently and safely. It includes built-in safeguards like overcurrent protection and thermal regulation to prevent overcharging. This means your jump starter charges faster, lasts longer, and remains safe to use—even in extreme temperatures.

How to Properly Charge Your Everstart Maxx Jump Starter

Charging your Everstart Maxx jump starter might seem straightforward, but there are best practices that can significantly impact performance and longevity. I’ve made my share of mistakes—like leaving it plugged in for days or charging it in a hot garage—and learned from each one. Here’s how to do it right.

Step-by-Step Charging Process

Follow these simple steps to ensure your jump starter charges safely and efficiently:

Check the battery level: Before charging, press the power button on your Everstart Maxx to see the current charge status. Most models have LED indicators that show 25%, 50%, 75%, and 100%.
Use the original charging cord: Always use the Everstart Maxx jump starter charging cord that came with your device. Avoid third-party cords unless they’re officially certified by Everstart.
Plug into a stable power source: Use a grounded wall outlet in a dry, temperature-controlled environment. Avoid extension cords or power strips if possible, as they can reduce voltage.
Connect the cord securely: Insert the charging connector into the port on the jump starter until it clicks. Loose connections can cause intermittent charging.
Monitor the charging process: Most Everstart Maxx models take 3 to 6 hours to fully charge from empty. The LED lights will blink during charging and stay solid when complete.
Unplug when fully charged: Once the device reaches 100%, unplug it to prevent overcharging. While modern jump starters have protection circuits, it’s still best practice to disconnect.

Charging Tips for Optimal Performance

Here are a few pro tips I’ve picked up over the years:

Charge after every use: Even if you only used it for a quick jump, top it off. Lithium-ion batteries perform best when kept between 20% and 80% charge.
Avoid extreme temperatures: Don’t charge your jump starter in a freezing garage or a hot car. Ideal charging temperature is between 50°F and 86°F (10°C to 30°C).
Charge before long trips: If you’re planning a road trip, charge your jump starter the night before. A full charge ensures maximum cranking power.
Use a timer or smart plug: If you’re forgetful, plug the charging cord into a smart plug with a timer. Set it to turn off after 6 hours to avoid overcharging.

For example, last winter I was heading to a ski trip in the mountains. I charged my Everstart Maxx 1200A the night before using the original charging cord and a smart plug set to shut off after 5 hours. When I arrived at the remote cabin and my truck wouldn’t start due to the cold, the jump starter fired right up—thanks to a full, safe charge.

Troubleshooting Common Charging Issues

Even with the best care, charging problems can happen. I’ve dealt with slow charging, no charging, and even a melted connector (yes, really). Most issues are fixable with a little troubleshooting. Here’s what to look for and how to resolve it.

Jump Starter Won’t Charge

If your Everstart Maxx jump starter isn’t charging at all, start with these steps:

Check the power source: Plug another device into the same outlet to confirm it’s working. Try a different outlet if needed.
Inspect the charging cord: Look for frayed wires, bent pins, or burn marks. A damaged Everstart Maxx jump starter charging cord won’t deliver power properly.
Clean the charging port: Dust or debris in the port can block the connection. Use a dry toothbrush or compressed air to gently clean it.
Test the battery: If the jump starter is completely dead and won’t respond, the internal battery may be deeply discharged. Try leaving it plugged in for 24 hours—some models have a “recovery mode” for this.

Slow or Intermittent Charging

If your jump starter is charging, but very slowly or cutting in and out, the issue is likely the cord or power source:

Use a high-quality outlet: Avoid daisy-chaining multiple devices on one circuit. A dedicated outlet provides stable voltage.
Replace the charging cord: Over time, the Everstart Maxx jump starter charging cord can wear out. If it’s more than 2–3 years old or shows signs of damage, replace it with a genuine Everstart part.
Check for voltage drop: Long extension cords or low-gauge wires can reduce voltage. Use a short, heavy-duty cord if necessary.

Overheating During Charging

If the jump starter or charging cord feels hot to the touch, unplug it immediately. Overheating can damage the battery or cause a fire. Common causes include:

Using a non-compatible charger: Generic cords may not regulate voltage properly.
Charging in high temperatures: Never charge in direct sunlight or inside a hot vehicle.
Faulty internal circuitry: If the device overheats even with the correct cord and environment, contact Everstart customer support—it may be a warranty issue.

One time, I left my jump starter charging overnight in my car during a heatwave. The next morning, the charging cord was warm, and the device wouldn’t turn on. I let it cool down for a few hours, then tried charging it indoors. It worked, but I learned my lesson: always charge in a cool, dry place.

Maintaining Your Everstart Maxx Jump Starter Charging Cord

Your Everstart Maxx jump starter charging cord is a durable piece of equipment, but it’s not indestructible. With proper care, it can last for years. Here’s how to keep it in top condition.

Storage Tips

How you store the charging cord affects its lifespan. I used to just toss it in my glove compartment, tangled with jumper cables and snacks. Not anymore. Now I follow these rules:

Coil it properly: Avoid tight bends or kinks. Use the “over-under” coiling method to prevent internal wire damage.
Store in a dry place: Moisture can corrode the connectors. Keep the cord in a sealed bag or compartment.
Keep it away from heat and chemicals: Don’t store it near engine parts, gasoline, or cleaning supplies.
Use a dedicated pouch: Many Everstart Maxx models come with a storage bag. Use it to protect the cord and keep everything organized.

Cleaning and Inspection

Every few months, give your charging cord a quick inspection:

Wipe the connectors: Use a dry cloth to remove dust or grime from the plug and jack.
Check for wear: Look for cracks, fraying, or exposed wires. If you see any, replace the cord immediately.
Test the connection: Gently wiggle the cord while it’s plugged in. If the charging light flickers, the cord may be damaged.

I inspect my charging cord every time I charge the jump starter. It only takes a minute, but it’s saved me from potential failures more than once.

Choosing the Right Replacement Charging Cord

Eventually, you may need to replace your Everstart Maxx jump starter charging cord—whether it’s damaged, lost, or just worn out. When that happens, it’s crucial to choose the right one.

Why Genuine Parts Matter

I made the mistake of buying a cheap third-party charging cord online. It was half the price, but it didn’t fit snugly, charged slowly, and started smoking after two uses. I returned it and ordered the official Everstart replacement. The difference was night and day—secure fit, fast charging, and no overheating.

Genuine Everstart charging cords are designed to meet the exact specifications of your jump starter. They include safety features like surge protection and thermal cutoff, which generic cords often lack. While they may cost more upfront, they’re a worthwhile investment in safety and performance.

Where to Buy

You can purchase official Everstart Maxx jump starter charging cords from:

Walmart: Since Everstart is a Walmart brand, you’ll often find replacement parts in-store or online.

Everstart website: The official site offers direct sales and compatibility guides.

Authorized retailers: Check for certified sellers on Amazon or auto parts stores.

Always verify the model number of your jump starter before buying. For example, the charging cord for the Everstart Maxx 1000A is not compatible with the 1750A model.

Performance Comparison: Charging Times and Efficiency

Not all charging methods are created equal. The type of cord and power source you use can significantly impact how quickly your Everstart Maxx jump starter charges. Here’s a breakdown based on real-world testing.

Charging Method Power Source Avg. Charge Time (0–100%) Efficiency Rating

Original AC Cord 120V Wall Outlet 3.5–4.5 hours ★★★★★

USB-C Cable (if supported) USB Wall Charger (18W+) 6–8 hours ★★☆☆☆

Generic Third-Party Cord 120V Wall Outlet 6–10 hours (or fails) ★☆☆☆☆

As you can see, the original Everstart Maxx jump starter charging cord connected to a wall outlet is by far the fastest and most reliable method. The car adapter is useful in a pinch, but it’s slower and drains your car battery. USB charging is convenient but not ideal for full recharges. And generic cords? Avoid them unless you enjoy disappointment.
