When charging an electric wheelchair in daily use, it is very important to ensure the power connection is correct and safety is maintained. The following are some recommendations:

1. Read the User Manual:
Before starting to charge, be sure to read the user manual of the electric wheelchair thoroughly to understand the specific charging steps and precautions recommended by the manufacturer.

2. Check if the Battery and Charger Match:
Ensure that the charger used is the original one or a dedicated charger compatible with the specific wheelchair model. Using an incompatible charger may lead to battery damage or even safety hazards such as fire.

3. Ensure a Safe Charging Environment:
Place the wheelchair in a well-ventilated area, free of flammable materials, dry, and away from water sources for charging, to prevent safety issues caused by overheating or other electrical faults.

4. Turn Off the Power Switch:
Before connecting the power supply, turn off the power switch of the electric wheelchair to prevent accidental activation of the wheelchair that could cause injury.

5. Connect the Charger:
Correctly connect the charger to the wheelchair's battery port according to the instructions. Pay attention to not reverse the positive and negative terminals. Usually, the charger plug and battery socket have a foolproof design to ensure correct insertion.

6. Select the Power Outlet:
Use a properly grounded power outlet and ensure the outlet's load capacity is sufficient to support the power requirements of the wheelchair charger.

7. Observe the Charging Status:
During the charging process, pay attention to the indicator light on the charger to confirm the charging process is normal. Most chargers will have charging indicator lights, such as red light for charging and green light for fully charged or standby.

8. Avoid Overcharging:
Follow the manufacturer's recommended charging time. Generally, it is not recommended to continuously charge beyond the specified time. Overcharging can affect battery life and increase the risk of fire. Disconnect the power supply promptly after the battery is fully charged.

9. Perform Regular Battery Maintenance:
Regularly maintain the battery, including but not limited to keeping the battery terminals clean, avoiding complete discharge of the battery during prolonged non-use, and replacing the battery according to the recommended cycle.

When charging an electric wheelchair, always follow the operating guidelines in the product manual, while remaining vigilant and cautious to ensure the safety of the user and the surrounding environment.
