Check the power source for the egg and remote
Read the included parts and battery details for both devices.
Check the egg first
USB identifies the power source for some charging cables. It does not establish the connector shape at the egg. Match the cable to the exact model before buying a replacement.
Read the remote separately
Love Notes Smooth uses a pin charger for the egg and a CR2032 battery for the remote. A rechargeable egg does not tell you how the remote is powered.
