About this product

This is a portable cooling fan with a 900ml water tank, a seven-colour night light and a USB power interface, sold for living rooms, bedrooms and desks. Its cooling comes from moving air across a wetted pad, so the result depends far more on relative humidity than on the fan speed setting: in dry heat the drop in air temperature is noticeable, while in humid weather the air moves but does not feel much cooler. The tank size sets how long one fill lasts, and a larger tank means fewer trips rather than stronger cooling. Before you order, check three things: what supplies power, since a USB interface usually means you provide your own adapter and the airflow depends on the current it can deliver; where the fill opening is and whether you can reach and empty the tank for cleaning; and whether the pad or filter is replaceable, because a wetted pad that is never cleaned will start to smell. If the page does not state the current or wattage the fan draws, ask the seller before buying.

Pros & cons

Pros


  • Air that passes a wet pad feels cooler than plain fan air in dry heat
  • 900ml tank means fewer refills during an evening
  • Seven-colour night light doubles as a small ambient lamp
  • USB power lets you run it from a power bank or a laptop port

Cons


  • Cooling depends on low humidity, so humid weather limits the drop in temperature
  • USB interface usually means the power adapter is not included
  • A wetted pad left uncleaned will start to smell and needs replacing
  • Tank capacity changes runtime, not cooling strength
