Why Charging Your Everstart Jump Starter Matters

Imagine this: you’re late for work, you hop into your car, turn the key, and—nothing. The engine won’t start. Your phone’s at 5%, and you’re stuck in a quiet neighborhood with no one in sight. That’s when your Everstart jump starter becomes your best friend. But here’s the catch: it only works if it’s charged.

I’ve been there. A few years ago, I kept my jump starter in the trunk for emergencies, only to find it completely dead when I needed it most. That day taught me a hard lesson—storing a jump starter isn’t enough. You have to charge your Everstart jump starter regularly. Whether you own the Everstart 1200A, 1700A, or one of the newer lithium models, proper charging isn’t just about convenience. It’s about peace of mind, safety, and being ready for the unexpected. In this guide, I’ll walk you through everything you need to know—from understanding how these devices work to step-by-step charging instructions, troubleshooting tips, and how to keep your unit in peak condition for years.

Understanding Your Everstart Jump Starter: The Basics

What Is an Everstart Jump Starter?

An Everstart jump starter is a portable power pack designed to start a car, truck, or SUV when the vehicle battery is dead. Unlike traditional jumper cables that rely on another vehicle, Everstart models are self-contained. They store electrical energy in a built-in battery (usually lithium-ion or lead-acid) and deliver a powerful burst of current through jumper clamps to start your engine.

Everstart, a brand owned by Johnson Controls, is sold primarily at Walmart and is known for its reliability, affordability, and user-friendly design. These units often come with extra features like USB charging ports, LED flashlights, and even air compressors in some models.

Key Components You Need to Know

• Main Battery: The heart of the unit. Most newer models use lithium-ion, which is lighter and holds a charge longer than older lead-acid types.
• Jumper Cables & Clamps: Attached or detachable cables with red (positive) and black (negative) clamps for connecting to your car battery.
• Charging Port: Usually a DC input (barrel plug) or USB-C, depending on the model. This is where you plug in the charger.
• Power Button & Indicator Lights: Shows charge level and operational status. Some models have digital displays.
• USB Outputs: Let you charge phones, tablets, or other small devices in a pinch.
• LED Flashlight: Handy for nighttime jump starts or emergencies.

For example, the Everstart 1200A model has a 12,000 mAh lithium battery, dual USB ports, and a 12V DC outlet. It takes about 4–6 hours to charge fully using the included wall adapter. Knowing these specs helps you understand charging times and power output.

Lithium vs. Lead-Acid: What’s the Difference?

If you’re comparing older Everstart models (like the lead-acid 12V jump starters) with newer lithium ones, here’s the key difference:

• Lithium-Ion: Lighter, faster charging, longer shelf life, holds charge for months. Most common in modern Everstart units.
• Lead-Acid: Heavier, slower to charge, needs more frequent recharging (every 30–60 days), and can lose capacity if left uncharged.

When I upgraded from a lead-acid model to a lithium Everstart 1700A, I noticed the difference immediately—no more lugging around a 10-pound brick, and it charged in half the time. But both types require proper charging habits to avoid damage.

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

Step 1: Check the Current Charge Level

Before charging, always check how much power your Everstart has left. Most models have a power indicator button—press it, and LEDs will light up to show the charge level:

• 1–2 lights = Low (needs charging)
• 3–4 lights = Medium
• 5 lights = Full (or 100% on digital models)

For example, my Everstart 1700A has a digital percentage display. When it drops below 20%, I know it’s time to plug it in. If you ignore this, you risk the unit being too weak to jump-start your car when needed.

Step 2: Choose the Right Charging Method

Everstart jump starters support multiple charging options. Here’s how to use each one safely:

Option A: Wall Outlet Charging (Recommended)

• Use the original AC wall charger that came with your unit. It’s designed to deliver the correct voltage (usually 12V–15V) and current (1A–2A).
• Plug the charger into a standard household outlet (120V).
• Connect the DC plug (barrel connector) to the jump starter’s charging port.
• The indicator lights will flash or show a charging animation. On digital models, you’ll see a charging icon.

Tip: Avoid using third-party chargers unless they’re specifically rated for your model. I once used a random 12V adapter, and it overheated the charging port. Not fun.

Option B: Car Charger (12V DC)

• Use the included 12V car adapter (cigarette lighter plug).
• Insert it into your vehicle’s 12V socket (make sure the car is running or in accessory mode).
• Connect to the jump starter’s charging port.

This is great if you’re on the road. I used this method during a cross-country trip when my Everstart dropped to 30%. But remember: your car must be on. The 12V socket often cuts power when the engine is off.

Option C: USB Charging (For Select Models)

• Some newer Everstart models (like the 1200A with USB-C input) can be charged via USB-C from a laptop, power bank, or USB wall adapter.
• Use a high-quality USB-C cable (preferably the one included).
• Plug into a 5V/2A or higher USB source.

USB charging is slower—expect 6–8 hours for a full charge. I use this when I’m at my desk and don’t want to use the wall adapter.

Step 3: Monitor the Charging Process

Once connected, keep an eye on the indicators:

• Flashing lights or rising percentage: Normal charging.
• Solid lights or 100%: Fully charged. Disconnect to avoid overcharging (most models have auto-shutoff, but better safe than sorry).
• No response after 10 minutes: Check connections and charger.

Most Everstart units take 4–6 hours to charge fully from 0% using the wall adapter. USB or car charging may take longer.

Step 4: Disconnect and Store Properly

When charging is complete:

• Unplug the charger from the wall or car first.
• Then disconnect from the jump starter.
• Store in a cool, dry place. Avoid direct sunlight or extreme temperatures.

I keep mine in a padded bag in my trunk. It’s protected from heat, moisture, and accidental drops.

Best Practices for Long-Term Charging & Maintenance

How Often Should You Charge Your Everstart?

Here’s the golden rule: Charge your Everstart jump starter every 3–6 months, even if you haven’t used it.

• Lithium models: Can hold a charge for 6–12 months, but battery chemistry degrades over time. Recharging every 6 months keeps it healthy.
• Lead-acid models: Must be charged every 30–60 days. They can sulfate (a process where crystals form on the plates) if left uncharged, permanently reducing capacity.

I set a recurring calendar reminder every 5 months to check and charge mine. It takes 10 minutes and prevents surprises.

Never Let It Fully Discharge

Unlike older batteries, lithium-ion doesn’t like being drained to 0%. Deep discharges can shorten lifespan. If your Everstart shows 10% or lower, charge it ASAP.

One winter, I left my jump starter in my unheated garage for two months. When I checked, it was dead. After recharging, it worked—but the battery capacity dropped by 15%. Lesson learned.

Use the Right Charging Environment

• Temperature: Charge between 32°F (0°C) and 104°F (40°C). Extreme cold or heat can damage the battery.
• Ventilation: Don’t charge under pillows or in closed drawers. Heat builds up during charging.
• Moisture: Avoid humid areas (like bathrooms). Water can corrode connections.

I once charged mine in a damp basement corner. The charging port started corroding. Now I charge it on my kitchen counter, away from steam and spills.

Clean the Charging Port Regularly

Dust, lint, or corrosion can block the connection. Every few months:

• Unplug the charger.
• Use a soft, dry brush or compressed air to clean the charging port.
• If you see white/green corrosion (common in humid climates), gently wipe with a cotton swab dipped in vinegar, then dry thoroughly.

Troubleshooting Common Charging Problems

“My Everstart Won’t Charge—What Now?”

If your unit shows no signs of life when plugged in, try these steps:

1. Check the Charger

• Test the wall adapter with a multimeter (should output 12V–15V).
• Try a different outlet.
• Inspect the cable for fraying or bent pins.

I once thought my jump starter was broken, but the wall adapter’s fuse had blown. Replacing it fixed the issue.

2. Inspect the Charging Port

• Look for debris, bent pins, or corrosion.
• Wiggle the plug gently. If it feels loose, the port may be damaged.

3. Try a Different Charging Method

• If the wall charger isn’t working, try the car adapter or USB.
• If one method works, the issue is with the original charger.

4. Let It “Wake Up”

• Some lithium batteries have a safety mode. If deeply discharged, they won’t accept a charge immediately.
• Plug it in for 15–30 minutes. The battery may “wake up” and start charging.

This saved me once. My Everstart was at 0% for weeks. After 20 minutes on the charger, it finally responded.

“It Charges, But the Battery Drains Fast”

Possible causes:

• Old battery: Lithium batteries degrade after 3–5 years. If your unit is older, the capacity may be reduced.
• Parasitic drain: Some models have a small power draw even when off (e.g., to maintain LED lights). Not a major issue, but can drain over months.
• Faulty battery management system (BMS): Rare, but can cause erratic charging. Contact Everstart support.

“The Charging Port Gets Hot”

• Normal: Slight warmth is okay.
• Problem: If it’s hot to the touch, unplug immediately.
• Cause: Loose connection, damaged cable, or internal short.
• Solution: Use a different charger or contact customer service.

Final Tips to Keep Your Everstart Ready When You Need It

Charging your Everstart jump starter isn’t rocket science—but it is a habit that can save you from a lot of stress. Here are my final, hard-earned tips:

• Label it: Stick a reminder on your calendar or set a phone alert to check the charge every 5 months.
• Keep the charger handy: Store the wall adapter and car charger with the unit, not in a drawer across the house.
• Charge after use: If you jump-start your car, recharge the Everstart immediately. It may have lost 20–30% of its capacity.
• Don’t over-recharge: Once full, unplug it. Most models have auto-cutoff, but prolonged charging can generate heat.
• Test it occasionally: Press the power button every few months to see the charge level. This confirms the battery is alive.
• Store it upright: Prevents liquid leakage in lead-acid models and reduces stress on internal components.

One last story: A friend of mine ignored his Everstart for a year. When his car battery died in a snowstorm, the jump starter wouldn’t power on. He ended up waiting 45 minutes for a tow in freezing temps. Don’t be that person.

Your Everstart jump starter is more than a gadget—it’s a safety tool. By learning how to charge Everstart jump starter properly and maintaining it with care, you ensure it’s ready when life throws a curveball. Whether it’s a dead battery, a flat tire, or a stranded phone, a well-charged Everstart gives you control. And that? That’s peace of mind you can’t put a price on.
