How to choose
Read coverage as the maker's figure
The DREO and the Pelonis are each rated for up to 250 sq ft by the maker, while the ROVSUN lists heating coverage of 200 square meters. Wattage alone will not separate them: the ROVSUN draws 600 watts, the COSTWAY and the Tangkula draw 700 watts, and the DREO and the Pelonis draw 1500 watts. Compare the maker's coverage figure with your room's floor area before you choose.
Thermostat versus heat settings
A thermostat lets the heater cycle to hold a set temperature, while plain heat settings only pick a power level. All five picks have adjustable thermostats; the DREO sets from 41 to 95 degrees in 1-degree steps, and the COSTWAY knob turns from 32 to 194 degrees. The DREO and the Pelonis offer several wattage modes, so you can pick a lower output for mild days.
Placement and moving
Oil-filled radiators stand on the floor, and the ROVSUN fits on desktops and in corners at 12.6 by 5.9 by 15 inches. Keep the cord out of walkways, and plug the heater straight into a wall outlet rather than an extension cord.
