Why Your Everstart Jump Starter Isn’t Charging (And What to Do About It)

Picture this: you’re running late for work, your car battery is dead, and your trusty Everstart jump starter—the one you’ve relied on for years—won’t charge. Panic sets in. You plug it in, wait, and… nothing. The LED stays dark. Sound familiar? You’re not alone. A non-charging jump starter is one of the most frustrating roadside dilemmas, but here’s the good news: it’s often fixable. Whether it’s a simple connection issue or a deeper technical glitch, most problems can be resolved with a few troubleshooting steps.

As someone who’s spent years testing and reviewing portable jump starters, I’ve seen this scenario play out countless times. The key is to stay calm and methodical. In this guide, I’ll walk you through the most common reasons your Everstart jump starter isn’t charging, how to diagnose them, and—most importantly—how to fix them fast. No jargon, no fluff, just practical solutions that actually work. Let’s get your jump starter back in action.

1. Check the Basics: Power Source, Cables, and Connections

Before diving into complex fixes, let’s rule out the obvious. Often, the issue is as simple as a loose plug or a faulty outlet. Here’s how to start:

Test Your Charging Outlet

Plug your jump starter into a different wall outlet or use a phone charger to verify the outlet works. I once wasted 20 minutes troubleshooting a “broken” jump starter, only to realize my garage outlet had tripped the GFCI. Pro tip: Use a lamp or phone charger to confirm the outlet is live.

Inspect the Charging Cable and Adapter

• Look for frayed wires, bent pins, or discoloration on the charging cable. Even minor damage can disrupt power flow.
• Try a different USB-C or DC cable (depending on your Everstart model). Borrow one from a friend or use a phone cable you know works.
• Check the adapter (the brick that plugs into the wall). If it’s hot to the touch, smells burnt, or feels loose, replace it immediately.

Example: A reader once told me their Everstart Maxx wouldn’t charge until they swapped the included USB-C cable for a thicker, higher-quality one. The original cable couldn’t handle the required amperage!

Clean the Jump Starter’s Charging Port

Dust, lint, or corrosion in the port can prevent proper contact. Gently clean it with a dry toothbrush or compressed air. For stubborn grime, use a cotton swab dipped in isopropyl alcohol. Never use water or metal tools—this could short-circuit the device.

2. Diagnose Battery and Internal Issues

If the basics check out, the problem likely lies within the jump starter itself. Let’s explore the most common internal culprits.

Reset the Jump Starter

Everstart models (like the Maxx or Value Series) often have a built-in “sleep mode” to protect the battery. If the battery drains completely, it might need a reset:

1. Plug the charger into the jump starter.
2. Press and hold the power button for 10–15 seconds (even if the LED doesn’t light up).
3. Wait 2 minutes, then check if the charging LED activates.

Real-world fix: A mechanic friend used this trick on a dead Everstart Maxx after leaving it unused for 6 months. The battery “woke up” after the reset!

Test the Battery Voltage

A failing lithium-ion battery is a common reason for charging failure. Here’s how to check:

• Use a multimeter to measure the battery’s voltage (if you’re comfortable with electronics).
• For non-technical users: Plug the jump starter in, wait 30 minutes, then press the power button. If the LED flashes briefly or shows a partial charge (e.g., 1 out of 4 bars), the battery may be degraded.

Tip: Lithium-ion batteries degrade after 2–3 years of regular use. If your jump starter is older, this could be the root cause.

Check for Thermal Shutdown

Jump starters have safety features to prevent overheating. If the device gets too hot (e.g., left in a hot car), it may stop charging. Let it cool for 1–2 hours in a shaded area, then try again. Never charge a hot jump starter—it’s a fire risk.

3. Software and Firmware Glitches (Yes, Jump Starters Have Those Too!)

Modern Everstart jump starters are mini-computers with firmware that can glitch. Here’s how to tackle software-related issues.

Force a Firmware Reboot

Some models (like the Everstart Maxx with a digital display) have firmware that can freeze. Try this:

• Hold the power button and mode button simultaneously for 20 seconds.
• Unplug the charger, wait 10 seconds, then plug it back in.
• Wait 1–2 minutes to see if the charging indicator appears.

Why this works: It clears temporary memory errors, similar to restarting a frozen phone.

Update Firmware (If Available)

While Everstart doesn’t publicly release firmware updates, some retailers or customer support teams may provide them for specific models. Contact Everstart support and ask: “Are there any firmware updates for [your model]?” If yes, follow their instructions carefully.

Watch for Error Codes

Digital models (e.g., Everstart Maxx 1000A) display error codes like “E1” or “E2” on the screen. Here’s what they mean:

Error Code	Meaning	Solution
E1	Overvoltage	Unplug immediately. Try a different power source.
E2	Overheating	Let the device cool for 2+ hours.
E3	Battery fault	Contact Everstart support for battery replacement.

Note: Older analog models without screens won’t display codes, but may blink LEDs in patterns (e.g., 3 flashes = low battery).

4. Environmental and Usage Factors You Might Overlook

Sometimes, the issue isn’t the jump starter—it’s how or where you’re using it. Let’s address these hidden factors.

Temperature Extremes

Lithium-ion batteries hate cold and heat. Charging in temperatures below 32°F (0°C) or above 104°F (40°C) can trigger safety shutdowns. Store and charge your jump starter at room temperature (68–77°F / 20–25°C). Example: A reader in Alaska left their Everstart in a snowy garage overnight. It wouldn’t charge until they brought it inside and warmed it for 3 hours.

Deep Discharge Syndrome

If the battery is completely dead (0% charge), it may need a “trickle charge” to revive it:

• Use a 1A USB charger (slower than the standard 2.4A) to gently wake the battery.
• Charge for 1–2 hours, then switch to the regular adapter.

Warning: Never leave a deeply discharged battery charging unattended—it’s a fire hazard.

Overuse and Wear

Jump starters aren’t designed for daily use. If you’re charging it multiple times per week:

• The internal battery may be worn out.
• The charging port may be loose from repeated plugging/unplugging.

Tip: For frequent users, consider a heavy-duty model like the Everstart Maxx 1500A, which has a longer battery life.

5. When to Call in the Pros (Or Replace the Unit)

Not all fixes are DIY-friendly. Here’s when to seek help or cut your losses.

Contact Everstart Customer Support

If troubleshooting fails:

• Call Everstart at 1-800-222-5397 (U.S.) or visit their website.
• Have your model number, purchase date, and warranty info ready.
• Ask: “Is this covered under warranty?” Many Everstart models have 1–3 year warranties.

Real story: A friend’s Everstart Maxx wouldn’t charge after 18 months. Everstart sent a replacement battery for free, even though the warranty had just expired!

Third-Party Repair Services

Some electronics repair shops (e.g., Best Buy’s Geek Squad, local battery specialists) can replace jump starter batteries. Expect to pay $30–$80. Only use this option if the device is out of warranty and valuable to you.

Know When to Replace It

Replace your Everstart if:

• It’s over 3 years old and won’t hold a charge.
• Repair costs exceed 50% of a new unit’s price.
• It has visible damage (cracked casing, bulging battery).

Pro tip: When buying a replacement, look for models with LiFePO4 batteries—they last longer and handle cold better than standard lithium-ion.

6. Prevent Future Charging Problems: Maintenance Tips

An ounce of prevention is worth a pound of cure. Keep your jump starter healthy with these habits.

Charge It Regularly

Even if you don’t use it, recharge your jump starter every 3–6 months. Lithium-ion batteries degrade faster when fully discharged. Never store it at 0% charge.

Use the Right Charger

Stick to the original Everstart charger or a high-quality equivalent (e.g., Anker, Belkin). Cheap third-party chargers can damage the battery.

Store It Properly

• Keep it in a dry, cool place (not the trunk of your car).
• Use a protective case to prevent dust and moisture damage.
• Remove the clamps and store them separately to avoid corrosion.

Example: I keep my Everstart Maxx in a small toolbox in my closet—no more dead batteries after 8 months of storage!

Test It Monthly

Press the power button every month to check the battery level. If it’s below 50%, recharge it. This also ensures the device works when you need it.

Dealing with an Everstart jump starter not charging is stressful, but it’s rarely a lost cause. By methodically checking power sources, resetting the device, and addressing environmental factors, you’ll solve 80% of issues in under 30 minutes. Remember: most problems are fixable, but safety comes first. If you smell burning, see smoke, or the device is physically damaged, stop using it immediately and contact a professional.

Jump starters are lifelines, not just gadgets. Treat yours with care, and it’ll return the favor when you’re stranded on a dark road or rushing to an emergency. Now go charge that battery—you’ve got this.
