How to choose
Wattage, ECO mode and energy saving
Wattage sets how much power a heater draws: the Lerat draws 500 watts, the TABYIK and PRSOOY draw 600 watts, and the Cozy Products draws 750 watts. An ECO mode, like the TABYIK has, lowers output to hold warmth with less power. Compare wattage and ECO modes against the size of the space you heat, and treat rated coverage as the maker's figure.
Compare coverage and noise
Rated coverage is the maker's figure: the Lmkeji and PRSOOY are rated for up to 100 sq ft, and the Cozy Products is rated for up to 150 sq ft. Noise is stated too: the Lerat runs at 20 dB, the TABYIK at under 35 dB, and the Lmkeji and PRSOOY at under 45 dB. Match the coverage to your room and the noise figure to how quiet you need the room.
Thermostats, shutoffs and placement
A thermostat holds a set temperature by cycling the heater, while plain heat settings only pick a power level. The Lmkeji and Cozy Products have adjustable thermostats. Tip-over shutoff and overheat protection are built into the Lerat, TABYIK, Lmkeji and PRSOOY. Give any heater clear floor space, keep its cord out of walkways, and place it on a stable desk or floor surface.
