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

We’ve all been there. You’re ready to hit the road—maybe it’s a weekend camping trip, a long commute, or just a quick run to the grocery store—and your car won’t start. You reach for your trusty AVAPOW jump starter, hit the power button, and… nothing. No lights. No hum. Just silence. You check the charge, and your heart sinks: the AVAPOW jump starter isn’t charging. It’s frustrating, especially when you’ve relied on it before. But don’t panic. You’re not alone, and the good news is that most of the time, the issue isn’t permanent.

I’ve been in this exact situation. Last winter, after a week of sub-zero temperatures, I grabbed my AVAPOW A07, plugged it in, and got nothing. No charging indicator, no response—just a cold, unresponsive device. I was stuck, late for work, and honestly, a little annoyed. But after some trial, error, and a bit of research, I got it working again. That experience taught me a lot about how these devices behave when they’re not charging, and more importantly, how to fix them. Whether you’re dealing with a dead unit, a blinking light, or a charger that just won’t connect, this guide will walk you through the most common causes and practical fixes for an AVAPOW jump starter not charging. Let’s get your device back up and running.

Understanding How Your AVAPOW Jump Starter Charges

Before we dive into fixes, it helps to know how your AVAPOW jump starter actually charges. These devices aren’t like your phone or laptop. They use lithium-ion or LiFePO4 batteries, which are powerful but sensitive. Charging isn’t just plug-and-play—it involves internal circuits, safety cutoffs, and temperature sensors. If something goes wrong in that chain, your jump starter won’t charge, even if everything seems normal on the surface.

Charging Components and Their Roles

Your AVAPOW jump starter relies on several key parts to charge:

• Input port (usually USB-C or barrel jack): This is where the charger connects. It’s the first point of failure if it’s dirty, bent, or damaged.
• Charging circuitry: This regulates voltage and current, ensuring the battery isn’t overcharged or overheated.
• Battery management system (BMS): This is the brain. It monitors temperature, voltage, and charge cycles. If it detects a problem (like a deep discharge), it may disable charging to protect the battery.
• LED indicators: These tell you the charging status. A blinking red light might mean charging, while a solid red could indicate an error.
• Wall or car charger: The power source. Not all chargers are created equal, and using the wrong one can cause issues.

For example, the AVAPOW A07 uses a 12V/1A input, while the A12 supports USB-C PD (Power Delivery) at 18W. Using a 5V/1A phone charger on the A12 might not deliver enough power, causing slow or no charging.

Common Charging Modes and What They Mean

AVAPOW models often have different charging behaviors:

• Trickle charging: Used when the battery is very low. It starts slow and ramps up once the voltage rises.
• Fast charging: Kicks in once the battery reaches a safe threshold (usually around 10–20% charge).
• Overcharge protection: Stops charging when full. The lights may turn off or blink green.
• Deep discharge lockout: If the battery is below a critical voltage (e.g., 2.5V per cell), the BMS may block charging until a “wake-up” charge is applied.

Knowing this helps you interpret what’s happening. If your jump starter shows no lights at all, it could be in deep discharge lockout—a fixable issue, not a dead battery.

Step-by-Step Troubleshooting: Fixing an AVAPOW Jump Starter Not Charging

Now let’s get into the real work. Here’s a systematic approach to diagnosing and fixing your AVAPOW jump starter not charging issue. Follow these steps in order—they’re designed to catch the most common (and easiest) problems first.

1. Check the Charger and Cable

Start with the basics. A faulty charger or cable is the #1 cause of charging issues. I once wasted 30 minutes troubleshooting before realizing my cable was frayed at the connector. Here’s what to do:

• Use the original charger: AVAPOW includes a 12V/1A or USB-C PD charger. If you’re using a third-party one, swap it out. A 5V/1A phone charger won’t cut it for most models.
• Inspect the cable: Look for kinks, frays, or bent pins. Wiggle the cable near the ends while plugged in. If the charging light flickers, the cable is likely bad.
• Test with another device: Plug the charger into a phone or tablet. If it doesn’t charge, the issue is the charger, not the jump starter.
• Try a different cable: If your model uses USB-C, use a high-quality, PD-compatible cable. Cheap cables often lack the power delivery specs needed.

Pro tip: I keep a spare AVAPOW charger in my car and at home. It’s saved me twice when the original went missing or got damaged.

2. Inspect the Charging Port and Connections

Even with a good charger, a dirty or damaged port can prevent charging. Over time, dust, lint, or corrosion can build up inside the input port.

• Turn the device off (if possible) and unplug it.
• Use a flashlight to look inside the port: Check for lint, dust, or bent pins. A paperclip (straightened) or a plastic toothpick can gently remove debris. Never use metal tools—they can short the contacts.
• Wipe the connector: Use a cotton swab dipped in isopropyl alcohol (70% or higher) to clean the port. Let it dry completely before plugging in.
• Check for physical damage: If the port feels loose or wobbles, it may be cracked or broken. In this case, you’ll need professional repair or a replacement.

I once found a tiny piece of paper stuck in my A12’s USB-C port—leftover from a receipt I’d stored nearby. A quick clean, and it started charging again.

3. Test the Charging Environment

Temperature and power source matter. AVAPOW jump starters have built-in thermal protection. If they’re too hot or too cold, they won’t charge.

• Ideal charging temperature: 32°F to 104°F (0°C to 40°C). If your device was in a freezing car or a hot garage, let it sit at room temperature for 1–2 hours before charging.
• Avoid direct sunlight or heat sources: Charging near a radiator or in a hot car can trigger overheat protection.
• Use a stable power outlet: Plug the charger directly into a wall socket, not a power strip with other high-draw devices (like space heaters or microwaves). Voltage drops can confuse the BMS.

Real-world example: My neighbor tried charging his AVAPOW A07 in a 105°F garage. The unit stayed cold—no lights, no charging. After moving it to a cool basement, it charged fine the next day.

4. Perform a “Wake-Up” Charge (For Deeply Discharged Batteries)

This is a game-changer. If your jump starter has been unused for weeks or was fully drained, the battery might be in a “sleep” mode. The BMS cuts off charging to prevent damage, but a low-current “wake-up” can revive it.

• Use a low-power charger: A 5V/1A USB phone charger (or a USB port on a computer) can work. Plug it into the jump starter’s input.
• Leave it connected for 12–24 hours: This slowly raises the battery voltage. The lights might stay off or blink faintly—that’s okay.
• After 24 hours, switch to the original charger: Once the battery voltage rises above the BMS threshold, the full charger should work.

I’ve used this trick on my A07 after it sat for 3 months. After 18 hours on a USB port, the red charging light finally came on. Within 4 hours on the original charger, it was at 50%.

5. Reset the Battery Management System (BMS)

Sometimes the BMS gets stuck in a protective state. A manual reset can clear it.

• Fully discharge the jump starter: Turn it on, press the LED flashlight button, and let it run until it shuts off. This drains any residual power.

<

• Wait 30 minutes: Let the device cool and reset internally.
• Plug in the original charger: Leave it connected for at least 24 hours, even if no lights appear.
• Check the lights after 24 hours: If charging starts, great. If not, try the wake-up method above.

Note: This won’t work on all models, but it’s worth a try. AVAPOW doesn’t officially document this, but many users (including me) have had success.

Advanced Diagnostics: When the Problem Persists

If you’ve tried the steps above and your AVAPOW jump starter still isn’t charging, it’s time for deeper investigation. These issues are less common but still fixable—or at least diagnosable so you know what to do next.

Using a Multimeter to Check Voltage

A multimeter can tell you if the battery is truly dead or if the problem is elsewhere. Caution: Only attempt this if you’re comfortable with electronics. Opening the device voids the warranty.

• Turn off the jump starter and unplug it.

<

• Set the multimeter to DC voltage (20V range).

<

• Open the device (if possible): Most AVAPOW models have screws on the back. Remove them carefully.

<

• Locate the battery terminals: They’re usually labeled + and –. Touch the probes to them.

<

• Read the voltage: A healthy lithium-ion battery reads 10–12.6V (for a 3-cell pack). Below 9V indicates deep discharge. Below 6V may mean permanent damage.

If the voltage is very low but not zero, the wake-up charge method (above) might still work. If it’s 0V or near 0V, the battery may be dead.

Checking for Internal Damage or Faulty Components

Sometimes, physical damage or component failure is the culprit. Look for:

• Swollen or leaking battery: This is dangerous. Stop using the device immediately. A swollen battery can rupture or catch fire. Dispose of it properly at a battery recycling center.

<

• Burn marks or melted solder: Indicates a short circuit. This requires professional repair.

<

• Corroded circuit board: If the device was exposed to water or high humidity, corrosion can block charging.

I once found a tiny drop of soda inside my A12’s charging port. It caused corrosion that blocked all power. A thorough cleaning with alcohol fixed it—but only after I opened it up.

AVAPOW’s customer service is generally responsive. I got a replacement unit within a week when my A07’s port failed after 18 months.

Preventing Future Charging Problems

Once your jump starter is working again, take steps to avoid future issues. Prevention is always easier than repair.

Proper Storage and Maintenance

• Charge it every 3–6 months: Even if unused, lithium batteries degrade. Keep it at 50–70% charge for storage.

<

• Store in a cool, dry place: Avoid attics, garages, or cars—temperature swings damage batteries.

<

• Clean the port regularly: Wipe it with a dry cloth every few months to prevent dust buildup.

<

• Use a protective case: AVAPOW sells cases, or use a padded pouch to prevent drops and scratches.

I keep my A12 in a drawer with a silica gel pack to absorb moisture. It’s been flawless for 2 years.

Best Practices for Charging

• Always use the original charger and cable.

<

• Charge at room temperature.

<

• Don’t leave it plugged in for days: Overcharging can reduce battery life. Unplug once fully charged (lights turn off or green).

<

• Monitor charging: If it gets hot, unplug it. Let it cool, then resume.

Signs It’s Time to Replace Your Jump Starter

Even with care, batteries wear out. Replace your AVAPOW jump starter if:

• It holds less than 50% of its original capacity after 2–3 years.

<

• It takes much longer to charge.

<

• It fails to jump-start your car after a full charge.

<

• It shows physical damage (cracks, swelling).

Most AVAPOW models last 3–5 years with proper care. When it’s time to replace, consider upgrading to a newer model with better battery tech (like LiFePO4).
