Common Causes of Goal Zero Flip 20 Not Charging

Several factors can prevent your Goal Zero Flip 20 from charging devices. Understanding these causes is the first step towards finding a solution.

Insufficient Sunlight

The Flip 20 relies on direct sunlight to generate power. Cloudy conditions, shade, or the angle of the sun can significantly reduce its output.

Dirty Solar Panels

Dust, dirt, and debris can accumulate on the solar panels, blocking sunlight and reducing efficiency.

Connection Issues

Loose or faulty connections between the Flip 20, your device, and any connected power banks can interrupt the charging process.

Device Incompatibility

Some devices may not be compatible with the Flip 20’s output, or may require a higher amperage than the Flip 20 can deliver.

Internal Component Failure

While less common, internal component failure within the Flip 20 itself can also cause charging problems.

How to Fix Goal Zero Flip 20 Not Charging

Goal Zero Flip 20 troubleshooting flow chart

Here are several methods to troubleshoot and fix your Flip 20, starting with the simplest solutions and progressing to more advanced ones.

Method 1: Basic Checks & Sunlight Optimization

This is the first step for any troubleshooting. It’s quick, easy, and often resolves the issue.

Diagnosing the Issue

Confirm the Flip 20 is exposed to direct sunlight. Check for shadows or obstructions. Verify the USB cable connecting your device is securely plugged into both the Flip 20 and your device.

Fix Steps

  1. Positioning: Adjust the Flip 20 so that the solar panels face the sun directly. Experiment with different angles to maximize sunlight exposure.
  2. Cable Check: Unplug and re-plug the USB cable at both ends. Try a different USB cable known to be working.
  3. Device Test: Connect a different device to the Flip 20 to rule out a problem with your original device.

Testing

Observe if the charging indicator light illuminates when connected to a device in direct sunlight.

Method 2: Cleaning the Solar Panels

Dirt and debris significantly reduce the Flip 20’s efficiency.

Diagnosing the Issue

Visually inspect the solar panels for dirt, dust, bird droppings, or other obstructions.

Fix Steps

  1. Gentle Cleaning: Use a soft, damp cloth to gently wipe the solar panels. Avoid abrasive cleaners or scouring pads, as these can damage the surface.
  2. Stubborn Debris: For stubborn debris, use a mild soap solution and a soft cloth. Rinse thoroughly with clean water and dry with a clean, lint-free cloth.

Testing

After cleaning, place the Flip 20 in direct sunlight and check if it begins charging a device.

Method 3: Checking and Resetting the Flip 20

Sometimes a simple reset can resolve internal glitches.

Diagnosing the Issue

Observe the Flip 20 for any unusual behavior, such as flickering lights or a complete lack of response.

Fix Steps

  1. Disconnect: Disconnect any devices from the Flip 20.
  2. Sun Exposure: Place the Flip 20 in direct sunlight for at least 30 minutes to allow it to fully charge the internal battery (if applicable).
  3. Power Cycle: Although the Flip 20 doesn’t have a power button, allowing it to fully charge in the sun and then disconnecting/reconnecting a device can sometimes reset the internal circuitry.

Testing

Reconnect your device and observe if the Flip 20 begins charging.

Method 4: Using a Power Bank for Consistent Output

Sometimes, relying solely on the Flip 20’s direct output isn’t ideal, especially in fluctuating sunlight.

Diagnosing the Issue

If your device requires a consistent power source, the Flip 20’s variable output might not be sufficient.

Fix Steps

  1. Connect to Power Bank: Connect the Flip 20 to a Goal Zero power bank (or compatible power bank) to store the generated energy.
  2. Charge Device from Power Bank: Charge your device from the power bank instead of directly from the Flip 20.

Testing

Monitor the power bank’s charge level to confirm the Flip 20 is successfully transferring energy.

How to Prevent Future Charging Issues

Preventative maintenance can significantly reduce the chances of encountering problems with your Flip 20.

Regular Cleaning

Clean the solar panels regularly, especially after use in dusty or dirty environments.

Proper Storage

Store the Flip 20 in a clean, dry place when not in use. Avoid exposing it to extreme temperatures or humidity.

Cable Management

Protect the USB cable from damage by avoiding sharp bends or kinks.

Sunlight Optimization

Always position the Flip 20 for optimal sunlight exposure during use.

Pro Tips for Goal Zero Flip 20 Users

  • Angle Matters: Adjust the angle of the Flip 20 every hour or so to track the sun’s movement for maximum efficiency.
  • Cloudy Days: Even on cloudy days, the Flip 20 can still generate some power. Don’t dismiss it entirely.
  • Power Bank Pairing: Pairing the Flip 20 with a Goal Zero power bank is ideal for consistent charging, especially when sunlight is intermittent.
  • Avoid Overheating: While the Flip 20 is durable, prolonged exposure to extreme heat can degrade its performance.
  • Inspect Regularly: Periodically inspect the Flip 20 for any signs of physical damage, such as cracks or loose connections.

Professional Help

If you’ve tried all the troubleshooting steps and your Flip 20 still isn’t working, it might require professional repair.

Signs to Seek Professional Help

  • Visible physical damage to the solar panels or casing.
  • Complete lack of response, even in direct sunlight.
  • Internal component failure (indicated by unusual noises or smells).

Warranty Considerations

Check your Goal Zero warranty to see if your Flip 20 is still covered. Contact Goal Zero customer support for warranty claims or repair options.
