Common Causes of Goal Zero Flip 20 Not Charging
Several factors can prevent your Flip 20 from charging. Understanding these causes is the first step toward finding the right solution.
Faulty Charging Cable
The most frequent culprit is a damaged or incompatible charging cable. Cables can fray, break internally, or simply wear out over time.
Power Outlet Issues
A malfunctioning wall outlet or power strip can prevent the Flip 20 from receiving power.
Internal Battery Issues
Over time, the internal battery can degrade, reducing its capacity and potentially causing charging problems. This is more common with older units.
Charging Port Problems
Dust, debris, or physical damage to the charging port can interrupt the connection.
Temperature Extremes
Extreme temperatures (both hot and cold) can affect the battery’s ability to charge.
How to Fix Goal Zero Flip 20 Not Charging: Multiple Solutions

Here are several methods to troubleshoot and fix your Flip 20, ranging from quick checks to more involved solutions.
Method 1: Basic Troubleshooting (Quick Fix)
This is the first place to start. It addresses the most common and easily fixable issues.
Diagnosing the Issue
- Verify the charging cable is securely connected to both the Flip 20 and the power source.
- Check if the wall outlet is working by plugging in another device.
- Inspect the charging cable for any visible damage.
Fix Steps
- Try a Different Charging Cable: Use a known good USB cable to rule out a faulty cable. Goal Zero recommends using a 5V/2A charger for optimal charging.
- Test a Different Power Outlet: Plug the charger into a different wall outlet or a power strip you know is working.
- Restart the Flip 20: Press and hold the power button for 30 seconds. This can sometimes reset the internal circuitry.
Testing
Plug the Flip 20 back into the charger and observe if the charging indicator light illuminates.
Method 2: Cleaning the Charging Port
Dust and debris can accumulate in the charging port, preventing a secure connection.
Diagnosing the Issue
Visually inspect the charging port for any visible dust, lint, or debris.
Fix Steps
- Power Off the Flip 20: Ensure the device is turned off before cleaning.
- Use Compressed Air: Gently blow compressed air into the charging port to dislodge any loose particles.
- Use a Non-Conductive Tool (Optional): If compressed air isn’t enough, carefully use a plastic toothpick or a similar non-conductive tool to remove stubborn debris. Avoid using metal objects, as they could damage the port.
Testing
Plug the Flip 20 back into the charger and check for a charging indicator.
Method 3: Temperature Regulation
Extreme temperatures can hinder charging.
Diagnosing the Issue
Determine if the Flip 20 has been exposed to extreme heat or cold recently.
Fix Steps
- Move to a Moderate Temperature: Bring the Flip 20 to a room temperature environment (between 32°F and 104°F/0°C and 40°C).
- Allow to Stabilize: Give the device 30-60 minutes to reach a stable temperature before attempting to charge it.
Testing
Plug the Flip 20 into the charger and observe if it begins charging.
Method 4: Battery Reset (Advanced – Use with Caution)

This method attempts to recalibrate the battery management system. This should be used as a last resort, as incorrect execution could potentially cause further issues.
Diagnosing the Issue
If the Flip 20 shows a charging indicator but doesn’t seem to gain any charge, the battery management system might need a reset.
Fix Steps
- Fully Discharge the Battery: Allow the Flip 20 to completely discharge until it shuts off automatically.
- Connect to Charger: Connect the Flip 20 to a known good charger.
- Monitor Charging: Let it charge uninterrupted for at least 24 hours. This allows the battery management system to recalibrate.
Testing
Check the battery level after 24 hours. If it still doesn’t charge properly, the battery may be failing.
How to Prevent Future Charging Issues

Preventative maintenance can significantly extend the life of your Flip 20 and minimize charging problems.
Proper Storage
Store the Flip 20 in a cool, dry place away from direct sunlight and extreme temperatures.
Regular Use
Avoid leaving the Flip 20 unused for extended periods. Regularly charging and discharging the battery helps maintain its health.
Cable Care
Handle the charging cable with care, avoiding kinks, bends, and excessive pulling.
Cleaning
Periodically clean the charging port with compressed air to prevent dust buildup.
Pro Tips for Goal Zero Flip 20 Owners
