48 million single-use green propane bottles end up in landfills each year. By contrast the refillable Ignik Gas Growler is more economical than single-use 16-ounce bottles and more portable than traditional 20-lb propane tanks. Each refill costs roughly the same as one single-use 16-ounce bottle but provides 5 times the burn time saving you money while you spare the landfill from another 5 bottles. Composed of a DOT-approved welded steel propane tank with 5-pound (1.2 gallon) capacity the Growler can be refilled at your local propane service stations just the same as bigger tanks. The compact Ignik Gas Growler is ideal for situations that require portability or when your space is limited such as camping RVing boating fishing tailgating overland etc. The kit includes everything you need to fuel your existing stove heater or other propane appliances. The 4-foot hose with adapter connects to most types of propane-burning devices including all 1-inch 20UNEF connectors which includes many popular 2-burner camp stoves as well as 0.5-inch QCC1/OPD compatible products such as standard home BBQ grills.
