One of the most common misconceptions about jump starters is that they’re “always ready.” But like your phone or laptop, they need to be charged regularly. The internal battery will slowly lose charge over time—even when not in use. That’s why it’s crucial to keep it topped up, especially if you live in a cold climate or don’t drive often.

Why Charging Matters

Think of your jump starter like a fire extinguisher. You hope you never need it, but if you do, it has to work. A dead jump starter is as useful as a paperweight when your car won’t start. Regular charging ensures that the battery maintains its capacity and longevity. Most manufacturers recommend charging the unit every 3 to 6 months, even if you haven’t used it. This prevents deep discharge, which can permanently damage lithium-ion batteries.

Also, charging your jump starter isn’t just about readiness—it’s about safety. A poorly maintained battery can overheat, leak, or in rare cases, fail during use. By following the correct charging procedure, you protect both the device and yourself.

What You’ll Need to Charge the Everstart Jump Starter 750 Amp

Charging your Everstart Jump Starter 750 Amp is straightforward, but you’ll need a few things to do it safely and effectively. The good news? Most of these items are probably already in your home.

Essential Charging Equipment

Original Charging Cable: The Everstart 750 Amp typically comes with a USB-C or micro-USB charging cable (depending on the model). Always use the cable provided or a high-quality replacement.
Power Adapter: A standard wall charger (5V/2A or higher) works best. Avoid using low-power chargers like those for Bluetooth headphones—they’ll charge too slowly.
Power Source: A wall outlet is ideal. You can also use a car charger (12V DC) if you’re on the go, but wall charging is faster and more reliable.
Clean, Dry Workspace: Choose a flat, dry surface away from water, heat sources, or flammable materials.

Optional but Helpful Tools

Multimeter: To check the battery voltage if you suspect a problem.
Soft Cloth: For cleaning the charging port and terminals.
Owner’s Manual: If you still have it, it’s a great reference for model-specific instructions.

Pro tip: Always inspect the charging cable and ports before plugging in. Look for frayed wires, bent pins, or dirt buildup. A damaged cable can cause slow charging or even pose a fire risk.

Step-by-Step Guide to Charging the Everstart Jump Starter 750 Amp

Now that you’ve got everything ready, let’s walk through the charging process. Don’t worry—it’s simpler than it sounds. Follow these steps carefully, and you’ll have your jump starter fully charged in no time.

Step 1: Locate the Charging Port

First, find the charging port on your Everstart Jump Starter. On most 750 Amp models, it’s a USB-C or micro-USB port located on the side or front of the unit. It’s usually labeled with a small battery or lightning bolt icon. If you’re unsure, check the user manual or look for a port that matches your charging cable.

Example: On the Everstart JS750 model, the charging port is a USB-C port on the right side, next to the power button and LED indicators.

Step 2: Connect the Charging Cable

Plug one end of the charging cable into the jump starter’s charging port. Make sure it’s inserted fully and securely. Then, plug the other end into your power adapter. Finally, connect the adapter to a wall outlet.

Important: Always plug the adapter into the wall after connecting the cable to the jump starter. This prevents power surges that could damage the device.

Step 3: Check the Charging Indicator

Once connected, look for the LED indicator lights on the jump starter. Most models have a series of lights that show the battery level:

Red Light: Charging in progress.
Green Light: Fully charged.
Flashing Red: Possible error (e.g., faulty connection or overheating).

If the red light is on, charging has started. If no lights appear, double-check your connections and try a different outlet.

Step 4: Monitor the Charging Process

Charging time varies depending on the battery’s current level and the power source. On average, it takes about 3 to 4 hours to fully charge the Everstart 750 Amp from empty using a 5V/2A wall charger. If you’re using a car charger or a lower-power adapter, it may take longer.

Tip: Don’t leave the jump starter unattended for long periods while charging, especially if it’s in a hot car or near flammable materials. While modern jump starters have safety features, it’s always better to be cautious.

Step 5: Disconnect When Fully Charged

Once the green light stays on (or all LED bars are lit), the jump starter is fully charged. Unplug the cable from the wall first, then from the device. This helps prevent electrical surges.

Pro tip: Even if you’re not planning to use the jump starter right away, store it in a cool, dry place with at least 50% charge. This helps preserve battery health.

Tips for Maintaining Battery Health and Longevity

Charging your Everstart Jump Starter 750 Amp correctly is only half the battle. To keep it working reliably for years, you need to maintain it properly. Here are some practical tips to extend its lifespan and performance.

Charge Regularly—Even When Not in Use

Lithium-ion batteries don’t like to be completely drained. If you let your jump starter sit at 0% for too long, the battery can enter a “deep discharge” state, making it difficult—or impossible—to recharge. To avoid this, charge the unit every 3 to 6 months, even if you haven’t used it.

Example: If you charge your jump starter every time you get an oil change (every 3,000–5,000 miles), you’ll likely stay on top of it without thinking.

Avoid Extreme Temperatures

Heat and cold are enemies of battery life. Don’t leave your jump starter in a hot car during summer or in freezing conditions during winter. Ideal storage temperature is between 50°F and 77°F (10°C to 25°C).

Why it matters: High temperatures can cause the battery to degrade faster, while cold temperatures reduce its ability to hold a charge.

Use the Right Charger

Always use a charger that matches the recommended voltage and current. The Everstart 750 Amp typically charges at 5V/2A. Using a charger with lower output (like 5V/1A) will work, but it’ll take longer. Using a higher-voltage charger (like 9V or 12V) can damage the battery.

Tip: Look for chargers labeled “fast charging” or “QC 3.0” only if your jump starter supports it. Most basic models do not.

Keep the Ports Clean

Dust, dirt, and moisture can build up in the charging port over time, leading to poor connections. Use a soft, dry cloth or a can of compressed air to gently clean the port every few months.

Warning: Never use water or cleaning solutions near the charging port. If moisture gets inside, it can cause corrosion or short circuits.

Test the Jump Starter Periodically

Even if you’re not using it to jump a car, test the jump starter every few months. Turn it on, check the LED lights, and try charging a phone via USB. This ensures all functions are working and the battery holds a charge.

Common Charging Issues and Troubleshooting

Sometimes, things don’t go as planned. Your jump starter might not charge, charge slowly, or show error lights. Don’t panic—most issues are easy to fix.

Issue 1: No Lights When Plugged In

If you plug in the charger and nothing happens, check the following:

Is the outlet working? Test it with another device.
Is the charging cable damaged? Try a different cable.
Is the battery completely dead? Some jump starters won’t charge if the battery is below a certain threshold. Try leaving it plugged in for 30 minutes to see if it “wakes up.”

Issue 2: Charging Is Very Slow

If the red light is on but the charge isn’t progressing, the problem might be the power source. Car chargers and low-power adapters can take much longer. Switch to a wall outlet with a 5V/2A or higher charger.

Issue 3: Flashing Red Light or Error Code

A flashing red light usually indicates a problem. Common causes include:

Overheating: Let the unit cool down before retrying.
Reverse polarity: Make sure you’re not trying to jump a car incorrectly (this shouldn’t affect charging, but some models have shared circuits).
Internal fault: If the problem persists, contact Everstart customer support or consider replacing the unit.

Issue 4: Battery Drains Quickly After Charging

If your jump starter loses charge within days of being fully charged, the battery may be aging. Lithium-ion batteries typically last 3 to 5 years with regular use. If it’s older than that, it might be time for a replacement.
