Compare the wattage with the coverage each maker gives: 100 sq ft for the Lmkeji and PRSOOY, and 43 sq ft for the shinic. Match both figures to the spot you want to warm.
Thermostats and heat controls
A thermostat holds a set temperature, while a single power switch only turns the heater on or off. The Lmkeji has a thermostat that holds a comfortable temperature. The PRSOOY has an independent On/Off switch with automatic power off when overheating. The shinic has one power switch, and the YOUCIDI sets its angle with a rotatable support. Pick the control style that fits how you adjust heat at your desk.
