To resolve this issue:
Step 1: Verify that the outlet itself has power.
Step 2: Verify that the cable is full seated in the adapter and in the charging dock.
Step 2b: Verify that the cable itself works and is not damaged. Either try a different cable or use the cable on a different device.
Step 3: Verify that the Starling is properly seated with the copper pins match the dock pins (Please note that the Starling must be removed from it’s clip to charge properly).
Step 3b: Make sure the Starling is removed from it’s case.
Step 4: Wipe down the metal contacts on the back of the Starling. Sometimes they get covered with gunk which does not allow charging to happen.
Step 6: Verify that there is a red light on the Starling while it is charging.
