The Mr. Heater Portable Buddy is North America's most popular portable propane heater, delivering radiant heat at 4,000 or 9,000 BTU per hour. This patented indoor-safe propane heater connects directly to a 1 lb propane cylinder and effectively heats enclosed spaces up to 225 square feet, making it ideal for tents, campers, workshops, job sites, garages, hunting blinds, ice fishing shanties, and emergency heating situations.

The heater features a compact, portable design with a fold-down handle and minimalistic footprint despite its powerful output. The swivel regulator allows connection to either disposable 1 lb cylinders or remote 20 lb tanks with an optional hose and filter (included in Costco bundle). Runtime is approximately 3 hours on high (9,000 BTU) and 6 hours on low (4,000 BTU) when using a 1 lb cylinder.

Safety features include an Oxygen Depletion Sensor (ODS) that automatically shuts off the heater if oxygen levels become unsafe, an accidental tip-over safety shut-off switch, and a thermal shutdown system. The heater uses a simple single-control start knob with integrated Piezo igniter for easy lighting. The unit is designed with flame-retardant materials and features patented cross-thread protection. This clean-burning, odor-free heater is safe for indoor use in enclosed spaces and operates at elevations up to 7,000 feet.
