User Manual

1. Introduction

This manual provides essential information for the safe and effective use of your eeTao 42V AC/DC Adapter Charger. This charger is designed to provide reliable power supply for compatible 42VDC electric devices, such as electric scooters or similar battery-powered equipment. Please read this manual thoroughly before operation and retain it for future reference.

The charger features a wide input voltage range (100-240VAC 50/60Hz) and incorporates multiple safety protections including Over Voltage Protection (OVP), Over Current Protection (OCP), and Short Circuit Protection (SCP) to ensure safe charging.

2. Important Safety Information

Always observe the following safety precautions to prevent injury or damage to the product and connected devices:

• Indoor Use Only: This charger is designed for indoor use in dry conditions. Do not expose it to rain, moisture, or extreme temperatures.
• Voltage Compatibility: Ensure the input voltage of the charger matches the local power supply (100-240VAC).
• Device Compatibility: Only connect this charger to devices that require a 42VDC power supply and have a compatible connector type (e.g., 4-pin or barrel connector as specified). Connecting to incompatible devices may cause damage.
• Ventilation: Do not cover the charger during operation. Ensure adequate ventilation to prevent overheating.
• Cable Integrity: Regularly inspect the power cord and charger for any signs of damage. Do not use if the cord is frayed or the charger casing is cracked.
• Unplug When Not In Use: Disconnect the charger from the power outlet when not in use or during electrical storms.
• Battery Condition: Important Note: Rechargeable batteries have a limited lifespan, typically 1 to 3 years. An old or dead battery may not accept a charge, which is not an indication of a faulty charger. If you suspect battery issues, use a voltmeter to test the charger's output.
• Children and Pets: Keep the charger and its cables out of reach of children and pets.
