About this item

Product details

The Mainstays Personal Ceramic Space Heater is a compact, corded electric heater made for warming a single indoor space rather than an entire home. With a maximum room size of 40 sq ft, it's sized for personal spots like a desk, a small office, or a study corner where you want focused warmth within arm's reach. Its small footprint measures 4.13 in W x 3.43 in L x 6.58 in H and it weighs just 1.05 lb, so it's easy to set in place or move from room to room as your needs change. Inside, PTC ceramic heating elements serve as the heating mechanism, turning cool room air into warm air for your personal area. Because it runs at a low decibel level, it suits quieter settings where you'd rather study or work without added distraction. For operation, safety, electrical details, and warranty, see the Key Features below.

Love this Lil Heater

This is my gonna be my winter bedside companion lol. This is the perfect little heater to keep next to the bed. My fingers often get cold if I'm on my phone or computer and this little heater is perfect to warm them right up. It has an emergency shot off that is triggered when knocked over. You can see the trigger in the third pic. Overall this is great for the bedside or at your desk!
