Propane tanks are durable, pressurized containers used for storing propane gas in liquid form, which can be used as an efficient, versatile energy source. Propane, or liquefied petroleum gas (LPG), is a widely used fuel for heating homes, powering appliances, fueling grills, and even providing energy for vehicles and industrial equipment. Propane tanks come in various sizes to accommodate different needs, ranging from small 1-pound cylinders for portable stoves to large 1,000-gallon tanks for home heating or commercial use.

The most common residential propane tank is the 20-pound size, typically used for BBQ grills and outdoor heaters, holding around 4.7 gallons of propane. Larger tanks like the 100-pound or 420-pound models are often used for more demanding applications like space heating, water heaters, and standby generators. These tanks can store up to 96 gallons of propane, making them ideal for homes in off-grid areas.
