How to Charge Everstart Maxx Jump Starter: A Complete Guide

Picture this: It’s a cold winter morning, you’re running late for work, and you turn the key in your car—only to hear that dreaded clicking sound. Your battery is dead. Again. You reach for your trusty Everstart Maxx jump starter, only to realize… it’s not charged either. Frustrating, right? That’s exactly what happened to me last January. I thought I was prepared, but I hadn’t checked the charge level in weeks. That morning taught me a valuable lesson: owning a jump starter is only half the battle. Knowing how to charge it properly is just as important.

The Everstart Maxx jump starter is a reliable, portable power source designed to jump-start dead car batteries, power small electronics, and even charge your phone in a pinch. But like any battery-powered device, it needs regular charging to stay ready when you need it most. Whether you’re a first-time owner or you’ve had yours for years, understanding how to charge your Everstart Maxx jump starter correctly can save you time, stress, and even extend the life of the unit. In this guide, I’ll walk you through everything you need to know—from the basics of charging to troubleshooting common issues—so you’re never left stranded again.

Understanding Your Everstart Maxx Jump Starter

Before we dive into the charging process, it’s important to understand what you’re working with. The Everstart Maxx jump starter is a portable lithium-ion battery pack designed to deliver a high burst of power to start a vehicle with a dead battery. It typically comes in different models, ranging from 600 to 2000 peak amps, depending on the size and intended use. These units often include additional features like built-in LED flashlights, USB ports for charging phones, and sometimes even air compressors.

Key Features That Affect Charging

One of the first things I noticed when I got my Everstart Maxx was the LED indicator lights. These aren’t just for show—they’re your best friend when it comes to monitoring charge status. Most models have a series of four or five lights that light up progressively as the battery charges. For example, if only one light is on, your unit is at about 25% charge. When all lights are solid, it’s fully charged. Some newer models even have digital displays that show exact percentages, which is super helpful.

Another feature to be aware of is the type of charging port. Most Everstart Maxx jump starters use a standard DC input port (often labeled “DC IN” or “CHARGE”) that accepts a 12V adapter. This means you’ll need to plug the included charger into a wall outlet—not your car’s cigarette lighter. While some people assume they can charge it in the car, that’s usually not the case unless the model specifically supports 12V charging (which most don’t). Always check your user manual to confirm.

Why Proper Charging Matters

Charging your jump starter isn’t just about convenience—it’s about safety and performance. Lithium-ion batteries, like the ones in the Everstart Maxx, are sensitive to overcharging, undercharging, and extreme temperatures. If you let the battery drain completely too often, it can shorten its lifespan. On the flip side, leaving it plugged in indefinitely can also cause stress on the battery. The goal is to maintain a healthy charge level—ideally between 50% and 100%—especially if you live in a cold climate where battery performance drops.

Think of it like your phone. You wouldn’t let it die every single day and then charge it to 100% right before you leave the house. You keep it topped off. The same principle applies here. A well-maintained jump starter is more likely to work when you need it, and it’ll last longer overall.

Step-by-Step Guide to Charging Your Everstart Maxx Jump Starter

Now that you know why charging matters, let’s get into the actual process. Charging your Everstart Maxx jump starter is straightforward, but there are a few steps you should follow to ensure it’s done safely and effectively. I’ll walk you through each one based on my own experience and the manufacturer’s recommendations.

Step 1: Check the Current Charge Level

Before you plug anything in, take a moment to check how much charge your jump starter currently has. Most models have a “Test” or “Check” button on the front. Press it, and the LED lights will show you the current battery level. If only one or two lights are on, it’s time to charge. If all lights are solid, you’re good to go—no need to plug it in unless you want to top it off.

Pro tip: I like to check mine every time I clean my car or do routine maintenance. It only takes a second, and it gives me peace of mind knowing it’s ready.

Step 2: Locate the Charging Port and Adapter

Next, find the charging port on your unit. It’s usually on the side or back and labeled “DC IN” or “CHARGE.” Make sure you have the correct charging adapter—this is the brick-like plug that came with your jump starter. Never use a third-party charger unless it’s specifically recommended by Everstart. Using the wrong voltage or amperage can damage the battery or even pose a fire risk.

In my case, I once tried using a generic 12V adapter from an old GPS unit. It didn’t fit properly, and the charging was inconsistent. I learned the hard way that the original charger is always the safest bet.

Step 3: Plug In and Begin Charging

Once you’ve confirmed you have the right adapter, plug it into a standard wall outlet. Then connect the other end to the jump starter’s charging port. You should see the LED lights begin to flash or change, indicating that charging has started. On most models, the lights will cycle through as the battery charges—for example, one light flashing, then two, and so on.

Charging time varies depending on the model and how depleted the battery is. A completely dead unit might take 3 to 6 hours to fully charge. If it’s only partially drained, it could be ready in under two hours. I usually charge mine overnight so it’s ready by morning.

Step 4: Monitor the Charging Process

While the jump starter is charging, it’s a good idea to check on it periodically. Make sure the adapter isn’t overheating and that the unit isn’t sitting on a flammable surface like a blanket or paper. Most modern jump starters have built-in safety features that prevent overcharging, but it’s still smart to keep an eye on things.

One thing I’ve noticed is that the charging process can slow down as the battery nears full capacity. This is normal—it’s called “trickle charging” and helps protect the battery. Don’t worry if it seems to take longer at the end.

Step 5: Disconnect When Fully Charged

Once all the LED lights are solid (or the digital display shows 100%), it’s time to unplug the charger. Leaving it connected for too long won’t usually cause damage thanks to built-in safeguards, but it’s still best practice to disconnect once charging is complete. This also helps save a tiny bit of energy and reduces wear on the adapter.

After disconnecting, I like to press the test button one more time to confirm the charge level. If all lights are on, I know it’s ready for action.

Best Practices for Maintaining Battery Health

Charging your Everstart Maxx jump starter correctly is important, but long-term care is what really keeps it performing at its best. I’ve learned a few habits over the years that have helped my unit stay reliable and last longer.

Charge Regularly, Even When Not in Use

One of the biggest mistakes people make is only charging their jump starter when they think they’ll need it. But lithium-ion batteries don’t like being stored at low charge levels. If you leave your unit at 10% for weeks or months, the battery can degrade faster. I recommend charging it at least once every 1–2 months, even if you haven’t used it.

For example, I keep mine in my garage near the door. Every time I grab my snow shovel in winter, I check the charge level. If it’s below 75%, I plug it in for a few hours. It’s become part of my seasonal routine.

Avoid Extreme Temperatures

Heat and cold are the enemies of battery life. Never leave your jump starter in a hot car during summer or in an unheated garage during winter. Extreme temperatures can damage the internal cells and reduce performance. I once left mine in my car on a 90°F day, and when I checked it later, the charge had dropped significantly. It took longer to recharge and didn’t hold as much power afterward.

Store your unit in a cool, dry place—like a closet or garage shelf—where temperatures stay moderate. If you live in a very cold climate, consider bringing it inside during winter months.

Use the Original Charger

As mentioned earlier, always use the charger that came with your Everstart Maxx. Third-party chargers might seem like a cost-saving option, but they can deliver inconsistent power or the wrong voltage, which can harm the battery over time. I made the mistake of buying a cheap replacement once, and it didn’t charge properly. I ended up returning it and ordering the official one from Walmart (where Everstart products are sold).

Keep It Clean and Dry

Dust, dirt, and moisture can interfere with the charging port and internal components. Wipe down the exterior with a dry cloth every few months, and make sure the charging port is free of debris. If you accidentally get it wet, let it dry completely before charging or using it.

Troubleshooting Common Charging Issues

Even with proper care, you might run into charging problems from time to time. I’ve dealt with a few myself, and while they’re usually fixable, it helps to know what to look for.

Jump Starter Won’t Charge

If your unit isn’t charging at all, start by checking the basics: Is the charger plugged in? Is the outlet working? Try a different outlet to rule out a power issue. If that doesn’t work, inspect the charging cable for damage—frayed wires or bent connectors can prevent charging.

Another possibility is that the battery is deeply discharged. Some lithium-ion batteries have a safety feature that prevents charging if the voltage drops too low. In this case, you might need to “jump-start” the jump starter using a special recovery mode (if your model supports it) or contact customer support.

Charging Is Slow or Inconsistent

If the LED lights are flashing erratically or the charge level isn’t increasing, the charger might be faulty or the battery could be aging. Try using a different charger (if you have a compatible one) or test the unit in a different location. If the problem persists, it might be time to replace the battery or the entire unit.

Overheating During Charging

It’s normal for the jump starter or charger to feel slightly warm during charging, but if it’s hot to the touch, unplug it immediately. Overheating can indicate a short circuit or battery failure. Let it cool down completely before attempting to charge again. If it continues to overheat, stop using it and contact Everstart support.

Charging Time and Performance Data

To give you a clearer picture of what to expect, here’s a comparison of charging times and performance for popular Everstart Maxx models. These numbers are based on manufacturer specs and real-world testing.

Model	Battery Capacity	Charging Time (0–100%)	Peak Amps	USB Ports
Everstart Maxx 600	12,000 mAh	3–4 hours	600A	2
Everstart Maxx 1000	18,000 mAh	4–5 hours	1000A	2
Everstart Maxx 2000	25,000 mAh	5–6 hours	2000A	3

As you can see, larger models take longer to charge but offer more power and longer run times. If you have a smaller car or only need occasional use, the 600A model might be sufficient. But if you drive a truck or SUV, or live in a cold climate, the 1000A or 2000A models are worth the extra charging time.

Final Thoughts and Tips

Charging your Everstart Maxx jump starter might seem like a small task, but it’s one of the most important things you can do to ensure it’s ready when you need it. I’ve learned that a little maintenance goes a long way. By checking the charge regularly, using the right charger, and storing it properly, you’ll extend its life and avoid those frustrating moments when it fails to work.

Remember, your jump starter is more than just a backup—it’s a safety tool. Whether you’re stuck in a parking lot, on a remote road, or just dealing with a dead battery on a cold morning, having a fully charged Everstart Maxx can make all the difference. So take a few minutes each month to check on it. Charge it when needed, keep it clean, and treat it well. In return, it’ll be there for you when it matters most.

And if you’re ever in doubt, don’t hesitate to consult the user manual or reach out to Everstart customer support. They’re usually very helpful and can guide you through any issues. After all, the goal isn’t just to own a jump starter—it’s to have peace of mind knowing it’s ready to go, every single time.
