Let’s be honest—few things are more frustrating than needing a jump start and realizing your jump starter is out of juice. I learned this the hard way last winter when my car wouldn’t start in a freezing parking lot. My Everstart jump starter, which had worked like a charm for years, just blinked red. No power. No help. Just silence. After that, I made it my mission to understand how to charge your Everstart jump starter the right way, every time. And now, I’m sharing everything I’ve learned so you never have to face that helpless moment.

Whether you’ve just bought your first Everstart jump starter or you’ve had it for a while and are noticing slower charge times or inconsistent performance, this guide is for you. Charging your jump starter isn’t rocket science, but doing it correctly ensures it’s ready when you need it most. We’ll walk through the charging process step by step, cover common mistakes, explain battery types, and even share some pro tips to extend your device’s life. Think of this as your friendly, no-nonsense manual—written not by a corporate rep, but by someone who’s been stuck in the rain with a dead battery and a blinking red light.

Understanding Your Everstart Jump Starter Model

Before we dive into charging methods, it’s important to know that not all Everstart jump starters are the same. Over the years, Everstart (a brand available at Walmart and other retailers) has released several models, each with different battery types, capacities, and charging requirements. Charging a lithium-ion jump starter is not the same as charging an older lead-acid model. So let’s start by identifying your device and its needs.

Identify Your Model Type

Most Everstart jump starters fall into two main categories: lithium-ion (Li-ion) and lead-acid (sealed lead-acid or SLA). Here’s how to tell which one you have:

• Look at the label: Flip your jump starter over and check the specifications. If it says “Li-ion” or “Lithium Polymer,” it’s a modern, lightweight model. These usually have capacities between 10,000 mAh and 20,000 mAh.
• Check the weight: Lithium models are significantly lighter—usually under 3 lbs. Lead-acid models feel heavier, often 5–10 lbs or more.
• Look at the charging port: Li-ion models typically use a USB-C or micro-USB port for charging. Lead-acid models often have a proprietary DC barrel plug.
• Review the manual or packaging: If you still have it, the model number (e.g., ES5000, ES12000) will tell you everything. Search it online to confirm battery type.

For example, the Everstart ES12000 is a popular 12,000 mAh lithium-ion model with USB-C charging and multiple power outputs. In contrast, the older Everstart ES5000 uses a sealed lead-acid battery and requires a 12V DC charger.

Why Battery Type Matters for Charging

The battery chemistry determines how your jump starter should be charged. Lithium-ion batteries:

• Charge faster (typically 2–4 hours)
• Don’t require full discharges
• Are sensitive to overcharging (but modern models have built-in protection)
• Can be charged via USB from a wall adapter, car charger, or even a power bank

Lead-acid batteries, on the other hand:

• Take longer to charge (6–12 hours)
• Benefit from occasional full discharges (but don’t require it)
• Need a dedicated 12V charger with the correct voltage and polarity
• Are more prone to sulfation if left discharged for long periods

Pro tip: If you’re unsure, err on the side of caution. Use the charger that came with your jump starter. Never use a random 12V adapter unless you’re certain it matches the voltage and plug size.

Step-by-Step Guide: How to Charge Your Everstart Jump Starter

Now that you know your model type, let’s walk through the actual charging process. Whether you’re using a lithium-ion or lead-acid model, the steps are straightforward—but skipping even one can lead to underperformance or damage.

Charging a Lithium-Ion Everstart Jump Starter

Most newer Everstart models (like the ES12000 or ES16000) fall into this category. Here’s how to charge them safely and effectively:

1. Find a reliable power source: Use a wall outlet, car USB port, or high-quality power bank. Avoid cheap chargers or public charging stations with unstable power.
2. Connect the USB cable: Use the USB-C or micro-USB cable that came with your jump starter. If lost, buy a certified replacement (look for “USB-IF certified” on the packaging).
3. Plug into the jump starter first, then the power source: This helps prevent power surges. Connect the cable to your jump starter, then plug the other end into the wall adapter or car charger.
4. Check the LED indicators: Most Everstart Li-ion models have 4 LED lights showing charge level. A blinking light means it’s charging. Solid lights mean it’s at that percentage (e.g., 2 solid = 50%).
5. Wait for full charge: Charging usually takes 2–4 hours. Don’t unplug early. Let it reach 100% (all 4 lights solid).
6. Unplug in reverse order: Remove from the power source first, then disconnect from the jump starter.

Example: I charge my ES12000 overnight using a 2.4A wall adapter. It goes from 25% to 100% in about 3.5 hours. I always check the lights before bed and in the morning to confirm it’s fully charged.

Charging a Lead-Acid Everstart Jump Starter

If you have an older model, you’ll need the original 12V DC charger. Here’s the process:

1. Use the correct charger: The charger should be labeled 12V DC, 1–2A, with the right plug size (usually 5.5mm x 2.1mm). Never use a car battery charger directly.
2. Plug the charger into the wall first, then connect to the jump starter: This reduces the risk of sparking or voltage spikes.
3. Ensure a secure connection: Wiggle the plug gently to make sure it’s seated. A loose connection can cause slow or incomplete charging.
4. Monitor the charging process: Some models have a red/green LED. Red = charging, Green = full. Others just show a steady light when charging.
5. Charge for 8–12 hours: Lead-acid batteries need time. Don’t rush it. A partial charge won’t give you full cranking power.
6. Unplug the charger first, then disconnect from the jump starter: This prevents any electrical feedback.

Tip: If your original charger is lost, buy a replacement from Walmart or Amazon. Look for “12V 2A DC power adapter for jump starters” and confirm the plug size. Avoid generic “universal” chargers unless they list your model.

Using a Car to Charge (Yes, It’s Possible)

Some Everstart models (especially lithium-ion) can be charged from your car’s 12V outlet (cigarette lighter). This is great for road trips or emergencies.

• Use a 12V to USB adapter (rated at least 2A).
• Connect your jump starter via USB.
• Turn the car’s ignition to “ACC” or “On” to power the outlet.
• Charge for 2–4 hours, depending on battery level.

Caution: Don’t leave it charging unattended for days. The car battery can drain if the jump starter draws too much power. Also, avoid charging in extreme heat (like a hot car in summer) as it can degrade battery life.

Best Practices for Charging and Battery Longevity

Charging your Everstart jump starter isn’t just about plugging it in—it’s about doing it in a way that keeps the battery healthy for years. Here are the best practices I’ve learned after owning three different models.

Charge After Every Use (Even If It’s Not Fully Drained)

Many people make the mistake of only charging their jump starter when it’s completely dead. But lithium-ion batteries actually last longer when you keep them between 20% and 80%. Think of it like a phone—frequent top-ups are better than full drain-and-recharge cycles.

• After jump-starting a car, plug it in as soon as possible.
• If you used it for USB charging (to power a phone), recharge it that day.
• Even if you only used 10% of the battery, a quick top-up prevents deep discharge.

Personal story: I once ignored a 15% battery after a quick phone charge. A week later, it wouldn’t turn on. The battery had gone into deep discharge protection mode. It took 48 hours on the charger to “wake it up.” Now, I recharge within 24 hours of any use.

Store It Properly When Not in Use

Jump starters aren’t used daily, so how you store them matters. Here’s what to do:

• Charge to 50–60% before long-term storage: This is the sweet spot for lithium-ion batteries. Full charge (100%) or empty (0%) accelerates degradation.
• Store in a cool, dry place: Avoid garages with extreme temperature swings or humidity. A closet or shelf works well.
• Recharge every 3–6 months: Even in storage, batteries self-discharge. Top them off every few months to maintain health.

Pro tip: Set a reminder on your phone every 4 months to check and recharge your jump starter—even if you haven’t used it.

Avoid Overcharging and Overheating

Modern Everstart models have built-in overcharge protection, but it’s still smart to be cautious.

• Don’t leave it plugged in for days: Once fully charged, unplug it. While the protection circuit cuts power, prolonged heat can still stress the battery.
• Charge in a well-ventilated area: Don’t tuck it under a blanket or in a closed drawer while charging.
• Avoid charging in direct sunlight or hot cars: Temperatures above 100°F (38°C) can damage lithium batteries.

Example: I once left my jump starter charging on the dashboard on a sunny day. The case got hot, and the charging stopped halfway. After cooling it down, it worked again—but I lost a few percentage points in capacity. Now, I charge it indoors.

Common Charging Problems and How to Fix Them

Even with the best care, issues can happen. Here are the most common charging problems and how to troubleshoot them.

Jump Starter Won’t Charge (No Lights, No Response)

This is scary, but often fixable:

• Check the power source: Try a different wall outlet or USB port. Use a phone to test if the outlet works.
• Inspect the cable: Look for frayed wires or bent pins. Try a different cable or charger.
• Clean the charging port: Use a dry toothbrush or compressed air to remove dust or debris.
• Try a “soft reset”: Press and hold the power button for 10–15 seconds. Some models reset the internal circuit this way.
• Wait 24–48 hours: If the battery is deeply discharged, it might need time to “wake up.” Leave it on the charger.

Note: If none of these work, the battery may be permanently damaged. Contact Everstart support or consider replacement.

Charging Is Very Slow or Stops Midway

This often points to a weak power source or faulty cable.

• Use a 2A or higher USB adapter: A 1A phone charger is too weak for fast charging.
• Avoid USB hubs or extension cords: Power loss over distance slows charging.
• Check for firmware updates: Some Everstart models have app connectivity. Update via the app if available.

Example: I once used a 1A car adapter and it took 8 hours to charge 50%. Switching to a 2.4A adapter cut it to 2 hours.

Battery Drains Fast After Charging

If your jump starter loses charge quickly, it’s likely a sign of battery aging.

• Cycle the battery: Fully charge, then fully discharge (by using it until it shuts off), then charge again. Do this 2–3 times. This can recalibrate the battery meter.
• Check for background loads: Some models have always-on USB ports or LCD screens that drain battery when not in use. Turn off all outputs.
• Consider replacement: Lithium batteries last 2–5 years with regular use. If it’s older, the battery may need replacing.
