Here are some general steps to repair a DC mini fan that is rechargeable and portable:

Check the battery: If the fan is not turning on or not running properly, check the battery to see if it is charged or needs to be replaced. If the battery is dead or not holding a charge, replace it with a new one.

Clean the fan blades: If the fan blades are dirty or clogged with debris, it can cause the fan to malfunction. Use a soft cloth or a brush to clean the blades.

Check the motor: If the fan is still not working, check the motor to see if it is functioning properly. You can do this by removing the front grille and gently spinning the blades. If the blades do not spin freely or make a grinding noise, the motor may need to be replaced.

Check the wiring: Check the wiring connections between the battery, motor, and switch to see if there are any loose or broken connections. If you find any loose or broken wires, re-solder them or replace them with new ones.

Replace the switch: If the fan still does not work, the switch may be faulty. You can replace the switch by unscrewing the casing and removing the old switch. Then, replace it with a new switch and reassemble the casing.

If none of these steps work, you may need to take your mini fan to a professional repair shop or contact the manufacturer for assistance.
