Portable Air Conditioner vs Air Cooler — UK, Which Should You Buy?

Both claim to cool a room. They do it completely differently — and the running-cost difference is drastic.

A portable AC draws around 1kW (roughly 25p/hour at a typical 24.5p/kWh tariff). An evaporative cooler draws 12–170W, under 1p to 4p/hour. The catch: an air cooler works best in dry heat. On humid nights a portable AC is the only real answer.
