Electric fans and portable air conditioners differ in cooling effectiveness and cost, with fans being more economical and portable while air conditioners provide better room cooling.

• Electric fans circulate air and aid sweat evaporation but do not lower room temperature
• Portable air conditioners reduce room temperature by extracting hot air and venting it outside
• Fans are cheaper to buy and operate compared to portable air conditioners
• Fans are lighter and more portable than portable air conditioners
