VEVOR or Thermomate Side-by-Side
Fuel type and power
VEVOR uses propane, delivering 42,000 BTU of heat for rapid warming. Thermomate relies on 120V electricity with 1.44 kW wattage. Gas provides high output for outdoor or RV use. Electric offers stable point-of-use heating indoors. Your choice depends on available power sources. Propane works where gas lines exist. Electricity suits under-sink locations with standard outlets.
