The Mr. Heater Big Buddy Portable Heater connects directly to two 1-pound propane cylinders, and it's the perfect solution for heating enclosed spaces, such as cabins of up to 450 square feet in size. This is easily one of the best portable heaters for your travels: two swivel regulators provide the ability to adapt usage from disposable cylinders to a remote gas supply with the purchase of a single hose and filter. To light the unit, simply push and rotate the knob. The built-in Piezo sparking mechanism will take care of the rest. With the Oxygen Depletion Sensor (ODS) and accidental tip-over safety shut-off, you can be sure that you'll enjoy years of comfortable indoor safe heat. The use of unauthorized accessories or attachments with this heater is expressly prohibited, may cause serious injury, and will void the warranty.
