He appreciates the convenience of the device when it comes to “hands-free” cooling, but the fan is only effective at first, then even inconvenient. “The fan mounted on the hat helps the wind blow directly to the face, can adjust the direction of the wind. At first, I liked them because they were unique, but when used it was quite noisy. When the fan broke, I had to remove the hat,” Hung said.

This idea can come from high-end protective equipment or helmets, equipped with fans for cooling and ventilation. Most mini fans on the market originate from China and of lesser-known brands. “Due to the low price and light weight to wear, this fan uses a small battery, so the capacity is also small. Therefore, it is not expected that it will be both convenient and meet the needs of cooling,” Mr. Tien said. He also advises users to consider when using the product because the product is worn on the body, there is a potential risk if the finishing quality is poor. Users should choose portable mini fan models of some well-known brands, making it more secure to use and able to cool in any position, instead of fixed as the above-mentioned wearable fans.
