How to Fix Goal Zero Sherpa 50 Not Charging or Delivering Power
Here are several methods to troubleshoot and resolve issues with your Goal Zero Sherpa 50, ranging from simple checks to more advanced solutions.
Method 1: Basic Checks & Reset (Quick Fix)
This is the first thing you should try. It addresses the most common issues quickly.
Diagnosing the Issue
Is the Sherpa 50 completely unresponsive? Does it show any charging lights when plugged in? Does it power devices intermittently?
Fix Steps
- Inspect the Cable: Check the USB-C cable for any visible damage (frays, bends, broken connectors). Try a different, known-working USB-C cable.
- Test the Power Source: Plug the Sherpa 50 into a different wall outlet. Ensure the outlet is functioning correctly. If using a solar panel, verify it’s receiving adequate sunlight and producing power.
- Power Cycle/Reset: Press and hold the power button for 30 seconds. This performs a hard reset and can resolve minor software glitches.
Testing
Plug the Sherpa 50 into a power source and see if it begins charging. Attempt to power a small device to confirm power delivery.
Method 2: Deep Dive – Charging Port & Battery Health
If the basic checks don’t work, let’s investigate the charging port and battery.
Diagnosing the Issue
The Sherpa 50 may be charging slowly, not at all, or displaying incorrect battery level indicators.
Fix Steps
- Clean the USB-C Port: Use a can of compressed air to carefully clean the USB-C port on the Sherpa 50. Dust or debris can obstruct the connection. Important: Do not use metal objects to clean the port!
- Check Charging Indicator Lights: Refer to the Goal Zero Sherpa 50 manual for the meaning of the different LED indicator lights. Understand what the lights mean to interpret the charging status.
- Battery Discharge/Charge Cycle: Allow the Sherpa 50 to fully discharge (until it won’t power any devices) and then fully recharge it. This can sometimes recalibrate the battery management system.
Testing
Monitor the charging indicator lights during the charging process. Check if the battery level indicator accurately reflects the charging progress.
Method 3: Firmware Update and Software Troubleshooting
Outdated firmware can cause various issues.
Diagnosing the Issue
The Sherpa 50 may exhibit erratic behavior, or specific features might not function correctly.
Fix Steps
- Download Goal Zero Software: Download the Goal Zero app (available for iOS and Android) or visit the Goal Zero website to download the latest firmware update tool for your Sherpa 50.
- Update Firmware: Follow the instructions provided with the software to update the firmware. Important: Do not interrupt the firmware update process!
- Factory Reset (Last Resort): If updating the firmware doesn’t resolve the issue, perform a factory reset through the Goal Zero app or software. Warning: This will erase all settings and data.
Testing
After the firmware update, test all functions of the Sherpa 50 to ensure they are working correctly.
How to Prevent Future Charging Issues
Preventative maintenance can greatly extend the life of your Sherpa 50.
- Use Quality Cables: Invest in high-quality USB-C cables that are designed for power delivery.
- Store Properly: Store the Sherpa 50 in a cool, dry place, away from direct sunlight and extreme temperatures.
- Regular Discharge/Charge Cycles: Perform a full discharge/charge cycle every few months to maintain battery health.
- Avoid Overloading: Don’t connect devices that exceed the Sherpa 50’s output capacity.
- Keep Firmware Updated: Regularly check for and install firmware updates.
Pro Tips for Goal Zero Sherpa 50 Owners
