Portable air cooler

An air cooler comprising:

• a chest body having a bottom, sidewalls, and an openable top that together define a chest interior;
• an air inlet in the chest body through which ambient air can flow into the chest interior;
• an air outlet in the chest body through which air from the chest interior can flow out of the chest interior;
• a fan operable to cause ambient air to flow into the chest interior through the air inlet and to cause air from the chest interior to flow out the air outlet;
• and
• a chilling member removeably insertable in the chest interior to define an airflow pathway from the air inlet to the air outlet, the chilling member being chillable to a temperature below the ambient temperature prior to operation of the portable air cooler,
• wherein when the fan is operated, air is caused to flow from the air inlet through the airflow pathway to the air outlet, and wherein the chilling member comprises a heat exchange facilitating structure that chills air flowing through the airflow pathway so that the air at the air outlet is a lower temperature than the ambient air.
