Common Causes of Goal Zero Sherpa 100AC Not Charging

Several factors can prevent your Sherpa 100AC from charging. Understanding these causes is the first step toward a solution.

Faulty Charging Cable

A damaged or incompatible charging cable is the most common culprit. Cables can fray, break internally, or simply be the wrong type for optimal charging speed.

Incorrect Power Source

Using an inadequate power adapter or a wall outlet that isn’t functioning correctly can prevent charging. The Sherpa 100AC requires a specific wattage and voltage to charge efficiently.

Overheating or Extreme Temperatures

Like all batteries, the Sherpa 100AC’s battery performance is affected by temperature. Charging in extremely hot or cold environments can temporarily disable charging functionality to protect the battery.

Software Glitch

Occasionally, a temporary software glitch can interfere with the charging process. A simple reset can often resolve these issues.

Internal Battery Issues

In rarer cases, the battery itself may be failing or have a damaged cell, requiring professional attention.

This is the first and simplest step.

Diagnosing the Issue

Visually inspect the charging cable for any signs of damage, such as fraying, kinks, or exposed wires. Try a different known-working USB-C PD charging cable.

Fix Steps

  1. Disconnect the existing cable from both the Sherpa 100AC and the power source.
  2. Connect a new, known-working USB-C PD charging cable.
  3. Ensure the power adapter is the one specifically recommended for the Sherpa 100AC (65W USB-C PD adapter is ideal).
  4. Plug the adapter into a working wall outlet.

Testing

Observe the Sherpa 100AC’s display. If it starts charging, the original cable or adapter was the problem.

Method 2: Reset the Sherpa 100AC

A reset can resolve minor software glitches that may be preventing charging.

Diagnosing the Issue

If the display is frozen or unresponsive, a reset is a good first step.

Fix Steps

  1. Press and hold the power button for 20-30 seconds.
  2. Release the power button. The Sherpa 100AC should power off and then restart.

Testing

Once restarted, connect the charging cable and adapter. Check if the Sherpa 100AC begins to charge.

Method 3: Optimize Charging Environment

Temperature plays a crucial role in battery charging.

Diagnosing the Issue

If you’re charging in extreme temperatures (below 32°F or above 104°F), the Sherpa 100AC may refuse to charge to protect the battery.

Fix Steps

  1. Move the Sherpa 100AC to a room temperature environment (62°F – 72°F).
  2. Avoid direct sunlight or placing it near heat sources.

Testing

Connect the charging cable and adapter after moving the unit to a suitable temperature.

Method 4: Use a Different Power Source

The power source itself could be the issue.

Diagnosing the Issue

The wall outlet might be faulty or the power adapter might not be providing sufficient power.

Fix Steps

  1. Try a different wall outlet that you know is working.
  2. If using a wall adapter, ensure it’s rated for at least 65W USB-C PD output.
  3. Consider using a higher-wattage USB-C PD charger if available.

Testing

Observe if the Sherpa 100AC starts charging with the new power source.

Prevention Tips and Maintenance Advice

Preventing charging issues is easier than fixing them.

  • Use Recommended Cables & Adapters: Only use USB-C PD cables and 65W (or higher) USB-C PD adapters designed for the Sherpa 100AC.
  • Store Properly: Store the Sherpa 100AC in a cool, dry place when not in use.
  • Avoid Extreme Temperatures: Do not leave the unit in direct sunlight or expose it to freezing temperatures for extended periods.
  • Regularly Check Cables: Inspect charging cables for damage and replace them if necessary.
  • Firmware Updates: Check for firmware updates on the Goal Zero website and install them to maintain optimal performance.

Pro Tips

  • Charging from a Car: While you can charge the Sherpa 100AC from a car adapter, it’s generally much slower than using a wall outlet. Use a high-output car charger (USB-C PD) for faster charging.
  • Simultaneous Use & Charging: The Sherpa 100AC can be used while charging, but it will charge slower.
  • Deep Discharge: Avoid completely draining the battery frequently. While occasional deep discharges are okay, consistently running the battery to 0% can shorten its lifespan.
  • Long-Term Storage: For long-term storage, charge the Sherpa 100AC to around 60-80% capacity.
  • Display Indicators: Familiarize yourself with the Sherpa 100AC’s display indicators to quickly identify charging status and potential issues.
  • Resetting Errors: If you encounter an error code on the display, consult the Goal Zero support website for specific troubleshooting steps related to that code.
  • USB-C PD Protocol: Ensure your USB-C charger supports the Power Delivery (PD) protocol for optimal charging compatibility.

Professional Help

If you’ve tried all the troubleshooting steps above and your Sherpa 100AC still isn’t charging, it may have an internal problem.

  • Signs to Seek Professional Help: If the unit is physically damaged, exhibits unusual noises, or shows error messages that persist after resetting, contact Goal Zero support.
  • What to Look For in a Service Provider: Contact Goal Zero directly for authorized repair centers or warranty service.
  • Typical Cost Ranges: Repair costs can vary depending on the issue. Battery replacements are often the most expensive repair.
  • Warranty Considerations: Check your warranty status before seeking repairs. Goal Zero offers warranties on their products.
