9" Personal Heater effectively keeps you nice and warm in various environments. With three heat levels, you can easily manipulate the temperature to meet your needs. The fan-only mode allows the heater to circulate the air without activating the heating element, providing a comfortable breeze without heating the room. Personal heater offers multiple features to ensure the safety of you and others while in use. Tip-over protection automatically shuts the heater off if knocked over or tilted beyond a certain angle, and overheat protection automatically shuts the heater off if internal components reach dangerously high temperatures. The easy-to-use mechanical controls are user-friendly, and the portable design keeps you warm anywhere, no matter your location.
