Everstart 1200 Peak Amp Jump Starter Not Charging? Try This Fix

Picture this: You’re running late for work, it’s a cold morning, and your car won’t start. You reach into your trunk for your trusty Everstart 1200 peak amp jump starter, press the power button—and nothing happens. The screen stays dark. No lights. No hum. Just silence. Your heart sinks. You’ve relied on this device to get you out of tight spots before, and now, when you need it most, it’s completely dead. You plug it into the wall charger, wait a few hours, and still—nothing. Sound familiar?

You’re not alone. Thousands of drivers across the country have faced this frustrating issue with their Everstart 1200 jump starter. Whether you bought it from Walmart, used it to jump-start a friend’s truck last winter, or simply stored it in your garage for emergencies, a jump starter that won’t charge is about as useful as a chocolate teapot. But before you toss it in the recycling bin or head back to the store for a replacement, there’s good news: many of these units can be revived with a few simple troubleshooting steps. In this guide, I’ll walk you through exactly what to do when your Everstart 1200 peak amp jump starter not charging issue strikes—and how to fix it without spending another dime.

Why Your Everstart 1200 Jump Starter Won’t Charge

Let’s start by understanding why your jump starter might refuse to charge in the first place. Jump starters like the Everstart 1200 are built with lithium-ion or lithium-polymer batteries, which are powerful but sensitive. Unlike traditional car batteries, these compact power packs require careful handling and proper charging habits. When they stop charging, it’s usually not because the unit is “broken”—it’s often due to one of several common, fixable issues.

Battery Protection Mode

One of the most common reasons your Everstart 1200 won’t charge is that it’s entered battery protection mode. This is a built-in safety feature designed to prevent over-discharge, overheating, or short circuits. If the internal battery voltage drops too low—say, after being stored for months without use—the unit may shut down completely to protect itself. When this happens, the jump starter appears “dead” even though the battery still has some life left.

For example, imagine you used your jump starter to start your car last winter, then tossed it in the back of your SUV and forgot about it. Over the next six months, the battery slowly drained due to self-discharge. By the time you need it again, the voltage has dropped below the safe threshold, and the protection circuit kicks in. The result? No lights, no response—even when plugged in.

Faulty or Incompatible Charger

Another frequent culprit is the charging cable or power adapter. The Everstart 1200 typically comes with a standard DC charging cable that plugs into a wall outlet. But if the cable is damaged, frayed, or not making a solid connection, the unit won’t charge—even if it seems like it’s plugged in.

I once helped a friend troubleshoot his jump starter, and we spent nearly an hour checking the battery and ports before realizing the charging cable had a tiny break near the plug. It looked fine on the outside, but internally, the wires were severed. Swapping it with a known-good cable fixed the issue instantly. Always inspect your charger for physical damage, and try using a different cable if possible.

Charging Port or Internal Connection Issues

Over time, the charging port on your jump starter can become loose or corroded, especially if it’s been exposed to moisture or dust. A loose connection prevents proper power transfer, so even if the charger is working, the unit won’t charge.

Additionally, internal wiring or solder joints can degrade, particularly if the unit has been dropped or jostled around in your vehicle. These micro-fractures aren’t always visible, but they can interrupt the charging circuit. If you’ve dropped your jump starter recently or noticed it behaving erratically, this could be the root cause.

Software or Firmware Glitch

Yes, even jump starters can have software issues. The Everstart 1200 has a small onboard computer that manages charging, safety protocols, and display functions. Sometimes, this system can freeze or glitch—similar to a smartphone that won’t turn on after an update.

In these cases, the hardware is fine, but the software is stuck in a loop or failed state. This is less common, but it does happen. A hard reset (which we’ll cover later) can often resolve these glitches and restore normal function.

Step-by-Step Troubleshooting Guide

Now that we’ve covered the possible causes, let’s dive into the practical steps you can take to revive your Everstart 1200 jump starter. Don’t worry—you don’t need to be an electrician. These fixes are simple, safe, and can be done in under 30 minutes with basic tools.

Step 1: Check the Charger and Cable

Start with the simplest fix: verify that your charger is working. Plug the charger into a different outlet—preferably one you know is functional, like the one your phone charges from. Try using a different charging cable if you have one. Look for any signs of damage: frayed wires, bent pins, or loose connectors.

Pro tip: Use a multimeter to test the output voltage of your charger. The Everstart 1200 typically charges at 12V DC. If your charger is outputting significantly less (say, 8V or lower), it’s likely faulty and needs replacement.

Step 2: Inspect the Charging Port

Next, examine the charging port on the jump starter itself. Look for dirt, dust, or corrosion. Use a can of compressed air to gently blow out any debris. If you see corrosion (a green or white powdery substance), carefully clean it with a cotton swab dipped in isopropyl alcohol. Let it dry completely before attempting to charge.

Also, check for physical damage. Is the port loose? Does the charging plug wiggle excessively? A loose port may need professional repair, but sometimes simply pressing the plug in firmly while charging can make a temporary connection.

Step 3: Try a Hard Reset

If the unit still won’t charge, try performing a hard reset. This can clear software glitches and reset the protection circuit. Here’s how:

• Disconnect the charger.
• Press and hold the power button for 10–15 seconds to drain any residual power.
• Wait 2–3 minutes.
• Reconnect the charger and plug it into a working outlet.
• Wait 10–15 minutes and check for charging indicators (usually a blinking or solid light).

I’ve seen this reset trick bring back units that seemed completely dead. It’s like rebooting a frozen computer—sometimes all it takes is a fresh start.

Step 4: Use a Different Power Source

Sometimes the issue isn’t the jump starter—it’s the power source. Try charging from a different outlet, preferably one on a different circuit. Avoid using power strips or extension cords, as they can limit current flow. If you’re charging in a garage or outdoor outlet, test with an indoor outlet instead.

Bonus tip: If you have access to a 12V car charger (like the kind used for portable coolers), you can try charging the jump starter through your vehicle’s cigarette lighter. This bypasses wall outlets entirely and can help determine if the issue is with your home’s electrical system.

Step 5: Jump-Start the Jump Starter (Yes, Really!)

This one sounds crazy, but it works. If your Everstart 1200 has entered deep protection mode due to low voltage, it may need a “jump” to wake it up. Here’s how:

• Use a fully charged car battery or another jump starter.
• Connect the Everstart’s clamps to the battery (red to positive, black to negative).
• Wait 2–5 minutes.
• Disconnect and immediately plug the Everstart into its charger.

This brief surge of power can “kickstart” the internal circuitry and allow normal charging to resume. I’ve used this method successfully on three different units, and it’s saved me from buying replacements.

Preventing Future Charging Issues

Now that you’ve (hopefully) revived your jump starter, let’s talk about how to keep it working reliably for years to come. Prevention is always better than repair—especially when you’re counting on this device in an emergency.

Charge Regularly, Even When Not in Use

Lithium batteries don’t like to be left idle. The manufacturer recommends charging your Everstart 1200 every 3–6 months, even if you haven’t used it. This prevents deep discharge and keeps the battery in optimal condition.

Set a calendar reminder on your phone: “Charge jump starter” every April and October. It takes less than an hour and could save you a lot of stress down the road.

Store in a Cool, Dry Place

Heat and moisture are the enemies of electronics. Avoid storing your jump starter in your car trunk during summer—temperatures can exceed 140°F, which degrades battery life. Instead, keep it in a garage, closet, or climate-controlled space.

Also, avoid placing it near windows or areas prone to humidity, like basements without dehumidifiers. A simple storage bin with a silica gel pack can help absorb excess moisture.

Use the Right Charger

Always use the original charger or a compatible replacement. Cheap, off-brand chargers may not provide the correct voltage or current, which can damage the battery over time. Look for chargers labeled “12V DC, 2A” or similar.

If you’ve lost your original charger, check Walmart’s website or contact Everstart customer service. They often sell replacement cables at a reasonable price.

Avoid Over-Discharging

Don’t use your jump starter until it’s completely dead. Most units have a low-battery warning light—when it comes on, recharge immediately. Draining the battery to zero repeatedly shortens its lifespan and increases the risk of entering protection mode.

Think of it like your phone: you don’t wait until it shuts off to charge it, right? Treat your jump starter the same way.

When to Replace Your Everstart 1200 Jump Starter

Despite your best efforts, there may come a time when your jump starter simply can’t be revived. Lithium batteries have a finite lifespan—typically 3–5 years with regular use. If your unit is older than that, or if it’s been through multiple deep discharges, it may be time to retire it.

Signs It’s Time to Replace

• The unit won’t hold a charge for more than a few hours.
• It takes longer than 4–6 hours to fully charge.
• The jump starter fails to start a car even when fully charged.
• You notice swelling, leaking, or a burning smell (stop using immediately).

Swelling is a serious red flag. It indicates a chemical reaction inside the battery, which can lead to fire or explosion. If you see this, disconnect the unit, place it in a safe, non-flammable area (like a metal bucket), and contact the manufacturer or local hazardous waste facility for disposal instructions.

Recycling and Disposal

Never throw a lithium battery in the trash. They contain hazardous materials and can pose a fire risk in landfills. Instead, take your old jump starter to a recycling center, electronics store (like Best Buy or Staples), or check with your local waste management service for battery drop-off locations.

Many retailers also offer trade-in programs or discounts on new units when you recycle your old one. It’s a win-win for you and the environment.
