This is a portable fan heater designed for indoor use to provide warmth in rooms, offices, or bedrooms.
It typically includes two heat settings (e.g. low and high) plus a regular fan (no-heat) mode.
Some units come with an adjustable thermostat so you can control and maintain the temperature.
Safety features like overheat protection and a tip-over switch are included to shut off the device if it gets too hot or is knocked over.
The design is compact and portable, often with a handle for easy movement.
