• KEEPS YOU WARM AT WORK – At 200-Watts and 682 BTUs, this low wattage mini space heater is ideal for use under the desk to keep your feet and legs warm. Best of all, because it’s low wattage, it won’t keep tripping the office circuit breaker every time you turn it on.
• YOUR PERSONAL SPACE HEATER – At 6 inches tall with a 4” x 4” footprint, this cute, small electric heater takes up minimal desktop space and is intended to heat up your immediate space at home or the office. Designed to warm you, not a room. For that, we recommend getting a Lasko 1500-Watt tower heater.

This energy-efficient, indoor ceramic heater draws about 2 amps and turns on with a flip of a switch. Compact and portable, MyHeat comes with a 6-foot cord and a 2-pronged plug. It’s also easily stored when not in use.

If this sounds familiar, then this little heater is just what you need to keep you comfortable year-round. Produces a quiet, white noise that won’t disrupt your co-workers. MyHeat is available in 4 fun colors (black, white, blue, and purple) and makes for a great gift.
• TRUSTED FOR GENERATIONS – Lasko has been making quality products for over 100 years. MyHeat is ETL Listed and comes with Automatic Overheat Protection. The on/off switch lights up to let you know the unit is on.
