A cool, fresh breeze on your desk or nightstand. This portable mini air cooler runs on USB, with a water tank, three fan speeds and a temperature display. Small enough to carry from room to room.
Instant cooling and fresh air for any small space, in a portable desktop cube
- Stuffy, hot air in small rooms
- Dry air that needs gentle humidifying
- Bulky air conditioners that cannot be moved
- Noisy fans that disturb sleep
Turn a stuffy corner into a cool, fresh breeze
Hot afternoons at the desk and sticky nights in bed, made bearable. A portable cube with three fan speeds, a water tank, and a readable temperature display brings the chill right where you sit or sleep.
Three speeds, one cube, zero hassle

Cool air, not just moving air
The water tank lets evaporation pull heat from the airflow, so the breeze feels cooler than a plain USB fan. It also adds a little moisture to dry air.

Read the room, at a glance
The LCD shows the temperature, with ON/OFF, MENU and a +/- dial underneath. You see when to nudge the speed up or down, no guessing.

Quiet at night, strong by day
Low is the sleep setting. High is for the afternoon. A built-in multicolour LED panel doubles as a dim bedside glow.

From sweaty desk to cooler corner
The heat that follows you
It is 3 p.m., the video call is running long and your shirt is sticking to the chair. Tonight it will be the same in bed. The room fan just pushes the same warm air around, and a full air conditioner is bulky, pricey and stays where it is bolted.
A cooler corner, finally
Fill the tank, plug in the USB cable, pick a speed. Water evaporating inside the cube takes the edge off the airflow, and the louvered grille sends it your way. Low for sleep, high for the afternoon. It fits a desk or a nightstand and follows you from room to room.

Questions and answers
It is an evaporative cooler. Water in the tank evaporates into the airflow and makes the breeze feel cooler than a plain fan. It cools your personal space, not a whole room, and needs water to do it.
Best in dry air. On muggy days evaporation slows, so expect a fresher breeze rather than a big drop in temperature.
Low speed is the sleep setting and the cooler is marketed as quiet in operation. High is more noticeable, so keep it on low overnight and away from the pillow.
The translucent window shows the level, so you can check at a glance. Run time depends on speed and room heat. Top up before each session.
Anywhere with a USB power source: desk, nightstand, kitchen counter. Power it from a laptop, power bank or wall adapter.
A USB fan only moves warm air. This adds a water tank for evaporative cooling, a humidify mode, a temperature display and an LED light panel.
