I work out of my truck 8 hours a day as a security officer. My truck is my office. It is not cost effective to run my truck air conditioner all day. I built this portable air conditioner to use in my truck and it works great.
1) 12 volt DC Fan
(My fan will run on AC and DC)
1) 4 inch 1/4 Bend PVC Hub
1) 4 inch RDR DR 35 PVC Adapter
1) 12 Volt DC Accessory Plug
1) Piece of Plywood
Already had this
6) Wood Screws
Cut the plywood to fit the inside lip of the cooler. This needs to be a snug fit so you don't loose air but not too tight as you will have trouble removing it.
Cut two holes in the plywood, one for the fan and one for the PVC exhaust.

Step 5: Portable Air Conditioner
Plug your DC Adapter into the fan and the other end into your vehicles 12 volt DC accessory plug. You are now ready to use your Portable Air Conditioner. The air will be cooler if you use bag ice, however bag ice will probably melt in about 2 1/2 hours. I freeze water in 1/2 gallon milk jugs. The ice will stay frozen twice as long but the air is not as cool as using bag ice. If you use milk jugs do not fill them up all the way. When water freezes it expands and will burst the milk jugs if they are filled to the top. If you like this project PLEASE VOTE FOR IT.
