4-Inch Mini Desktop Fan USB Powered Brushless Motor Black WT-T405

This 4-inch mini desktop fan is a compact personal cooling device intended for desk use. It measures 150 x 95 x 145mm and weighs 200g, so it occupies limited space on a desk, shelf, or bedside table. The fan is powered through a USB cord and runs on DC5V with a power consumption of 1.9-2.5W. Its brushless DC motor is rated for 25000 hours or more and is described as producing low noise with low power consumption. The single wind speed gear delivers 1100-1400RPM, giving a fixed airflow setting for close-range use. The black housing is made from ABS and PP plastics, and the package includes the fan plus one power line. This fan suits users who need a simple, USB-powered airflow source in an office, study area, or home workspace without adding a large appliance.

Features and Construction

The fan's construction and motor type are the main practical details. It uses a brushless DC motor and a two-material plastic housing, with a compact shape that fits small surfaces. The specifications below cover what is stated in the product information.

Material and Build

The housing is made from ABS and PP plastics, a combination that gives the fan a lightweight structure at 200g. ABS and PP are common plastics for small desktop appliances, and their use here keeps the unit easy to move by hand. The black colour applies to the overall product finish. No additional coatings or treatments are stated, so the material description is limited to ABS and PP. The fan's build supports the brushless motor assembly and the single wind speed gear, with a USB power cord as the only connection method.

Size and Practical Fit

At 150 x 95 x 145mm, the fan has a footprint that can sit beside a keyboard, monitor, or lamp without crowding the workspace. Its 200g weight makes it easy to reposition by hand. The 4-inch fan size refers to the blade or fan head diameter as described in the product name. There are no foldable parts or mounting brackets listed, so placement is limited to flat surfaces such as a desk or table. The USB cord provides the power connection, and no battery or wireless mode is stated.

Uses and Placement

This fan is designed for personal cooling at close range rather than whole-room air circulation. Its size, weight, and USB power source determine where it can be used and how it is positioned.

Office and Professional Use

On an office desk, the fan can be placed near a laptop or monitor and powered from a USB port or adapter. The 1100-1400RPM single-speed airflow is directed at the user's immediate area. The brushless motor is stated to run with low noise, which may suit shared or quiet work environments. Because it uses a USB cord, no mains socket is required beyond a compatible USB power source. The compact 150 x 95 x 145mm size allows it to remain on the desk without taking up much room.

Everyday Home Use

At home, the fan can be used on a bedside table, study desk, or kitchen counter where a USB power source is available. The black ABS and PP housing wipes clean with a dry or slightly damp cloth. Its 200g weight means it can be moved from room to room as needed. The single speed setting keeps operation simple, with no additional controls described. The fan is not stated as waterproof or suitable for outdoor use, so it is best kept in dry indoor areas.

Benefits and Buying Value

The main value points come from the brushless motor rating, low power consumption, and the compact USB-powered format. These features are relevant for users who want a small fan for extended desk use without a large appliance.

Reuse and Low Maintenance

The fan's brushless DC motor is rated for 25000 hours or more, which indicates a long service life under the stated conditions. Low power consumption of 1.9-2.5W means it draws little electricity during use. The ABS and PP housing can be wiped clean, and no special maintenance fluids are required. The USB power cord is the only connection item included, so there are no filters or belts to replace based on the supplied information. Working hours are described as long-term use, but no exact continuous runtime is given beyond the motor rating.

Why Choose This Product

This fan is a practical choice for a single user who needs fixed, close-range airflow from a USB source. Its 4-inch size, 200g weight, and 150 x 95 x 145mm dimensions make it easy to fit on a desk or table. The brushless motor, low noise description, and 1100-1400RPM speed cover the basic cooling needs of a personal workspace. The package includes one fan and one power line. No extra speeds, batteries, or accessories are included, so buyers should expect a simple single-speed USB fan with the stated specifications.
