USB Spray Air Cooler Desktop Fan – Bladeless, 200ml Tank, 7.5W, 36-45dB, for Home Office 10m²

This spray air cooler is designed to provide a cooler, more comfortable environment in your immediate workspace, using water evaporation rather than noisy fan blades. Operating at a whisper-quiet 36-45dB, it will not distract during conference calls, study sessions, or sleep. The bladeless motor design makes it safe around children and pets, while the mechanical three-speed control lets you tailor airflow to your needs. With a rated power of just 7.5W, it is energy-efficient enough to leave plugged in all day, and its compact 170mm x 122mm footprint fits easily beside a monitor or on a nightstand. The unit is available in white or green and comes with a USB cable for easy connection to a laptop, desktop, or power bank.

Features and Construction

Built around a brushless motor and a bladeless air delivery system, this cooler combines safety with low-maintenance operation. The 200ml water tank supplies evaporative cooling while also adding humidity to dry indoor air—ideal for air-conditioned offices or heated rooms.

Material and Build

The body is made from durable ABS plastic, and the water reservoir is designed for easy filling and cleaning. The rated voltage is DC 5V at 1.5A, and the entire unit draws only 7.5W of power, making it compatible with standard USB ports. The mechanical operation mode is straightforward and requires no batteries or complicated setup.

Size and Practical Fit

Measuring just 170mm wide and 122mm deep, this cooler slips onto a desk corner, shelf, or bedside table without taking up valuable space. The compact design suits small rooms up to 10m², and the absence of blades makes it suitable for environments where safety is a priority.

Uses and Placement

This cooler brings personal comfort to a variety of settings, from home offices and dorm rooms to workshops and caravan interiors. The combination of air movement and water evaporation helps to create a fresher microclimate around the user.

Event or Professional Use

In temporary workstations or trade show booths, the USB power source means it can run from a power bank or laptop. The low noise output ensures it will not interfere with conversations or audio equipment, and the bladeless design eliminates the risk of injury if accidentally bumped.

Everyday Home Use

Use it on a bedside table for gentle cooling while sleeping, or on a desk while working from home. The integrated humidification function helps counteract dry air from central heating or air conditioning, making the room feel less stuffy for up to 10m² spaces.

Benefits and Buying Value

This device delivers targeted cooling and humidification with minimal energy consumption and near-silent operation. Its simple mechanical controls mean no complex programming is required, and the bladeless build reduces maintenance compared to traditional fans with spinning blades.

Reuse and Low Maintenance

The only consumable is tap water for the 200ml tank, and cleaning the reservoir periodically prevents odour or scaling. The brushless motor has few moving parts, contributing to long-term reliability without oiling or belt replacement.

Why Choose This Product

If you need quiet, localised cooling in a small room or workspace without the draft and noise of a traditional fan, this USB air cooler offers an efficient and safe solution. The evaporative function helps with humidity too, making it a versatile addition to any desk or bedside setup.
