Mini Air-Cooler System from 12V Fan (Homemade form Trash)

  Mini Air-Cooler System from 12V Fan (Homemade form Trash)

  • Bottle
  • 12V, 1A Fan (From Computer)
  • 12 V 1A DC Charger ( I used my Camera Charger )
  • Some Ice pieces


  • Take a bottle and cut the head for fixing 12V DC fan in it.
  • make a circular hole in the center of the bottle ( for cooled air)
  • Now take the 12 V Fan. There will be four wires ( Red, Black,Blue and Yellow) and then cut the two wires ( yellow and blue)
  • Now connect the other two wires( Red and Black) to the 12V Charger
  • Now connect the 12V charger to the 220V AC Supply.
  • Enjoy cooled air 🙂

Note: I will be here again with some modification because it was just for experimental purpose :
