All four indicator lights are flashing, what should I do?

The portable charger is in a fault condition. If this occurs:

• Make sure the device is within the temperature range
  
• Verify connections—reconnect if needed.
  
• Press and hold the Power/Charge button to turn it off, then press the Power/Charge button to turn it back on.

If the indicator lights all continue to stay on after checking these, contact Customer Support for further assistance.
