The RJVW 4-inch fan is a compact cooling solution designed for close-range use in home offices or dorm rooms. Built primarily from impact-resistant plastic, it features a 360-degree rotatable frame that uses friction-fit hinges to hold its position. This lightweight design measures just 4 inches, making it an easy addition to even the most crowded nightstands or desks without taking up significant space.
Tests indicate that the fan performs most consistently when connected to a standard 5V/1A wall adapter. While it can run off a laptop USB port, those ports sometimes lack the amperage needed to reach the fan's maximum speed. The brushless motor is a specific engineering choice that helps reduce electrical interference, making it a good neighbor for sensitive audio equipment or computer peripherals.
Functional Features
- Three-speed controller allows for personalized airflow levels.
- Standard USB-A interface is compatible with most power banks and wall chargers.
- Quiet operation under 40dB supports focus during work or rest.
Because the USB cord is hard-wired into the unit, it is best kept in a permanent spot where the cable won't be frequently tugged or strained. To maintain performance, the blades should be kept clear of dust; however, since the front face is not removable, a small vacuum or compressed air is recommended for cleaning.
For those who appreciate a more traditional or "vintage" look, the Holmes Heritage metal fan provides a similar size with a classic copper finish.
