Portable USB Evaporative Air Cooler with Mist & Ice Cooling

A Fan That Just Moves Hot Air Around Isn’t Enough in Summer

A standard desk fan circulates the air in the room without cooling it. On a hot day, that means moving warm air across your face rather than providing any meaningful relief. This Portable USB Evaporative Air Cooler adds a water misting function to the airflow, converting water in the tank into fine water molecules that cool the air as it passes through before reaching you. It is USB-powered, runs on a built-in rechargeable battery, and is sized to sit on a desk or bedside table.

Important note on what this product is: This is a personal evaporative cooler — it uses water misting to cool the immediate airflow around you. It is not a compressor-based air conditioner and will not cool an entire room to a set temperature. It is best used as a personal cooling solution at close range, such as at a desk, bedside, or workstation.

What’s in the Box

• 1 × Air cooler fan
• 1 × Data/charging cable

Verified Specifications and What They Mean in Practice

• Atomisation / misting function — The cooler converts water from the tank into ultra-fine water molecules and blows them out with the airflow. This produces cooler air at the output compared to standard fan airflow without the same level of skin-drying effect that direct air conditioning can cause.
• Ice water compatible — The water tank can be filled with cold water or used with ice cubes to further lower the temperature of the mist output.
• 2-speed fan — Two fan speed settings (gear 1 and gear 2) allow you to adjust airflow intensity to suit the conditions.
• Atomisation modes — The misting function operates in two modes: gear 1 (continuous) and gear 2 (5-second interval/indirect).
• Touchscreen operation — The unit is controlled via a touchscreen interface rather than physical buttons.
• 25W rated power — Low power draw suitable for USB operation from a laptop, wall adaptor, or power bank.
• USB power input — Powered via USB, compatible with standard USB power sources.
• 1800mAh built-in battery — The built-in battery allows cordless operation. Charging time is 2.5–3 hours.
• Battery run time — Up to 6 hours on gear 1 (low); up to approximately 3 hours on strong gear. Actual run time depends on settings used.
• Brushed motor — Motor type as specified.
• Dimensions: 167 × 225 × 120mm — Compact desk-sized footprint.
• Colour: Ivory White — Single colour option.
• Two variants available — L7 Humidifying Air Cooler and Digital Display L8.

Who This Cooler Is Best Suited For

• People who work at a desk in a warm room — The compact dimensions and USB power make it a practical desk companion. Directed at your face and upper body, the mist and airflow provide personal cooling at close range.
• Bedroom use on warm nights — The battery allows cordless bedside use without needing a socket nearby. Up to 6 hours on the lower setting covers a night’s sleep in many conditions.
• Anyone who finds air conditioning too drying — Evaporative misting adds moisture to the airflow rather than removing it, which can be more comfortable for skin and airways than direct compressor air conditioning.
• Users who want portable cooling without installation — No installation, no refrigerant, no window unit. Fill the tank, power via USB, and use it immediately.
• Those who want to supplement existing cooling — Used alongside an air conditioning system, a personal cooler adds a directed, close-range cool airflow boost at your specific position.

How to Use It

Fill the water tank with water (cold water or ice cubes can be added for lower mist temperature). Connect the USB cable to charge or to a live USB power source for direct operation. Use the touchscreen to select your fan speed (gear 1 or 2) and misting mode (continuous or interval). Position the cooler to direct airflow toward you. For cordless use, charge fully first (2.5–3 hours) before disconnecting from power.
