Ever wonder what that rugged, rectangular container with handles is called? You’ve probably seen one used for fuel, water, or camping supplies.
It’s known as a jerry can—a simple yet durable container designed to hold about 20 liters of liquid, making it easy to carry and pour without spills.
Keep reading to learn how this classic design keeps you prepared in any situation.
What Exactly Is a Jerry Can?
A jerry can is a portable container, typically holding about 20 liters (5 U.S. gallons) of liquid. Its design makes it perfect for storing or transporting fuel, water, or other liquids safely. You can identify it by its rectangular or polygonal shape, which facilitates easy stacking and handling. Constructed from pressed steel or durable plastic, it provides a leak-resistant seal and withstands rough conditions. The built-in top handle allows for controlled pouring, and its narrow profile makes it less bulky during transport. Originally designed for military and industrial use, modern jerry cans prioritize portability, stability, and safety. They are versatile tools that serve not only for fueling vehicles but also for water transport and various utility tasks. For those seeking the best options, reviews highlight top propane tanks that offer superior quality and performance for similar storage purposes. Using a fuel stabilizer ensures stored fuel remains fresh and effective for generator operation. Storing fuel in a jerry can also requires the right 10W-30 oil for generator lubrication to maintain peak performance.
The Wartime Origins of the Jerry Can
The design of the jerry can originated in Germany during the 1930s military buildup. It was specifically developed to address the weaknesses of earlier fuel containers, which often leaked or broke when handled roughly. The German Wehrmacht created a steel can with a leak-resistant body, three handles for easy passing, and a flat-sided shape for stacking and storage. This innovation significantly improved wartime logistics by allowing soldiers to transfer fuel quickly and safely without spills. The design was tested during the Spanish Civil War to refine its performance under battlefield conditions. When Allied forces captured and used similar containers in North Africa, they adopted the design, leading to the nickname “jerry can”—a nod to its German origin. This durable, easy-to-handle container remains a staple in fuel storage and transport ever since. Modern charging systems even incorporate automatic battery chargers that ensure reliable power for vehicles that rely on jerry cans for extended range.
What Makes a Jerry Can Unique?
A jerry can is distinct from an ordinary fuel container primarily because of its innovative design features. Its rectangular, flat-sided body allows for efficient stacking and prevents it from rolling away. The three-handle system enhances portability: you can carry one by the center handle or lift two with the outer handles, making it easier to transport or pass along in a relay. The material—welded metal or reinforced plastic—ensures durability under tough conditions. For those powering portable generators, this robust construction is essential, much like choosing the best inverter for reliable performance. Knowing how to operate a scepter gas can correctly prevents spillage and frustration.
Additional design elements serve both function and safety. The X-shaped indentations on the sides strengthen the structure against deformation when loaded. The tight-sealing cap with a gasket prevents leaks, while the built-in spout facilitates pouring without needing a separate funnel. An integrated air vent ensures a smooth flow of fuel. Certified versions undergo rigorous testing, including drop and pressure tests, making these containers more robust and reliable than standard fuel jugs. This level of testing mirrors the quick test methods used to assess deep cycle battery health, ensuring both fuel containers and batteries remain dependable under demanding conditions.

Modern Uses for Jerry Cans
Modern uses for jerry cans extend far beyond their military origins. While their X-shaped indents and three-handle design were primarily developed for fuel transportation in wartime, these features now serve practical purposes in everyday life. Their significance lies in durability and ease of handling, making them invaluable for emergency preparedness, outdoor activities, and professional industries. You can use them to store backup fuel for generators or clean water during power outages. Campers appreciate their capacity to carry extra gas or water for extended trips, ensuring they are prepared for remote locations. Farmers rely on jerry cans to transport diesel to machinery, while construction crews use them to move lubricants on-site efficiently. A similar approach to monitoring fuel reserves involves knowing how to check your propane tank level to determine when to replace it. For those running electronic devices from a vehicle, selecting a suitable car battery ensures the power inverter operates reliably during extended use. Similarly, homeowners can protect sensitive electronics by installing whole house surge protectors to guard against power surges during storms.
The material quality of jerry cans—usually thick polyethylene or steel—ensures they stand up against rough handling and harsh conditions. This resilience makes them suitable for off-road overlanding expeditions or marine fuel runs, where durability is critical. You can also repurpose them domestically for storing household liquids such as cleaning solutions or greywater, provided you select food-safe variants when storing drinking water. Their robust construction and versatile design make jerry cans a dependable tool for a range of practical applications, whether in the field or at home.

Can You Store Fuel and Water in a Jerry Can Safely?
Storing fuel and water in a jerry can safely depends on using the correct container for each liquid—never mix them. Use a dedicated can for fuel and another for water because their compatibility and safety standards are different. Fuel cans are not food-grade and may retain residues in seams and coatings even after rinsing, which can pose health risks if you later drink from a fuel can. Water should only be stored in a certified food-grade container that is kept clean, dry, and stored in a cool, dark place. Always inspect fuel cans for cracks or corrosion before each use, store them upright in a well-ventilated, shaded location away from heat or flames, and keep them out of direct sunlight. For water, rinse and sanitize the container periodically, and fill it with potable water from a trusted source. Clearly label each container to avoid dangerous mix-ups and ensure safety. For reliable home backup power, a portable backup generator can utilize these stored fuel supplies during an outage, but always connect it with a properly installed transfer switch to prevent dangerous backfeeding. A car battery charger without a traditional charger offers an alternative method to jump-start a vehicle if stored fuel is unavailable for generator use.

Why the Jerry Can Design Endures
Durability is the key to its enduring design. Stamped steel with welded seams and X-shaped ribs provides resistance to rough handling and temperature fluctuations. While material options have evolved to include high-density polyethylene (HDPE) variants, the fundamental shape and structure remain the same. This consistency is reinforced by NATO’s ongoing use of the original specifications, highlighting its proven logistics value. For example, top solar battery chargers also prioritize durable construction and reliable power delivery for long-term off-grid use, ensuring reliable performance in demanding conditions. Similarly, a secure roof mount for solar panels can be critical for optimizing the energy collection these chargers depend on. For you, this translates into a simple, reliable liquid container that has stood the test of time and remains effective through decades of use.
