The VOOL Charger is intuitively designed to provide visual feedback during the charging process to assist you in understanding the status of your charging session.

The status lights are shown when:

• The charger is connected to a power source.

• The charger is ready to charge and the cable is properly connected.

• The charger has started charging.

• The charger has completed the charging.

• An error or issue occurred in the charging process.

• Smart charging has been initiated.
