HIMOVO Fan

Summer outings, camping trips and outdoor work tend to bring two problems at once: heat and insects. HIMOVO Fan, which appeared as a project on Kickstarter, sets out to address both in a single handheld device.

Airflow and control

The maker quotes a maximum wind speed of 11m/s, a figure the source describes as exceeding that of a typical household fan. Speed is adjustable across 1–100 levels, and four modes are listed: constant wind, natural wind, cool breeze and eco mode. An LED display shows information such as the current fan level and remaining battery.

Mosquito repeller and cooling

The headline feature is an ultrasonic mosquito repeller. According to the maker, it emits high-frequency sound inaudible to humans that is intended to keep mosquitoes away, without chemicals or smoke. The fan also includes a semiconductor cooling system that, the maker says, lowers the temperature of the airflow itself rather than simply moving warm air.

Power and design

• Built-in battery rated for up to 10 hours of continuous use, per the maker
• USB-C fast charging
• LED display for fan level and battery status
• Minimal, white-based design

The source reports that the campaign significantly exceeded its funding goal at an early stage. Independent verification of the repeller's effectiveness and the cooling system's performance is not provided in the source material.
