Disclosure: As an Amazon Associate, I earn from qualifying purchases.

This pack addresses the specific challenge of transporting significant volumes of liquid without relying on campsite taps or heavy glass bottles. The standout feature is the dual-unit configuration, which splits a 20-litre total capacity into two manageable 10-litre units, making it easier to distribute weight in a vehicle boot. However, the light white plastic construction is a limitation for long-term static storage, as it is not designed to withstand months of UV exposure or chemical off-gassing in a dormant motorhome. This product is best for short-duration camping trips and festival attendees who need flexible, portable water or fuel storage.

Solving the ‘No Tap’ Problem: Storing Water for Off-Grid UK Camping

The primary utility of this set lies in its ability to provide a reliable water source in locations where potable water is scarce. By offering a total capacity of 20 litres across two containers, it supports a two-to-three-day trip for a small group without the need for frequent refills. This capacity is significantly more practical than carrying multiple one-litre bottles, which consume valuable boot space and require constant handling.

The physical dimensions of each unit are 34cm in height, 28cm in width, and 14cm in depth. These measurements allow the cans to stack or sit side-by-side in standard vehicle trunks, accommodating the irregular shapes of car boots better than rigid, single large tanks. The light white plastic material keeps the overall weight manageable when empty, allowing users to fill them at home or at a service station before departure.

Unlike typical single-purpose fuel cans that are often opaque and heavy, this design prioritizes visibility and ease of handling. The top-fill mechanism with a removable cap simplifies the filling process, reducing the risk of spills that often occur with side-mounted spouts. This design choice makes it particularly suitable for users who need to fill the containers in tight spaces, such as a motorhome galley or a small camping table.

Managing Weight Distribution in a Vehicle Boot

Splitting the 20-litre volume into two 10-litre units offers a distinct advantage in weight distribution. A single 20-litre container filled with water weighs approximately 20kg, which can be difficult to lift and may strain the suspension of smaller vehicles if placed incorrectly. By using two 10-litre units, users can distribute the weight more evenly across the boot floor, reducing the risk of damage to the vehicle’s interior or suspension components.

This configuration also allows for greater flexibility in placement. If one can is needed for immediate use at the campsite, it can be moved separately from the second can, which remains in the vehicle for later use. This modularity is particularly useful for campers who need to access water frequently without having to carry the full 20-litre load every time.

Practicality for Festival and Campsite Use

For festival attendees, the ability to carry large volumes of water without relying on crowded tap points is a significant convenience. The 10-litre capacity per can is large enough to last a full day of hydration and cooking for a small group, reducing the need to queue for water. The durable plastic construction withstands the rough handling typical of festival environments, where containers are often placed on uneven ground or transported over long distances.

The removable cap allows for easy access when pouring water into jugs or kettles, a feature that is often missing in more rigid fuel containers. This ease of use makes it a practical choice for those who need to prepare hot drinks or wash up at their campsite without the hassle of complex spout mechanisms.

Why This Can Is Not for Long-Term Motorhome Winter Storage

While this product is excellent for active use during trips, it is not designed for long-term static storage in a motorhome or caravan that sits unused for months. The light white plastic, while durable for short-term use, is susceptible to UV degradation when exposed to direct sunlight over extended periods. This degradation can lead to material weakening and potential leaks, making it unsuitable for permanent water reservoirs.

Furthermore, plastic containers can experience off-gassing over time, which may affect the taste and quality of stored water. For users who need a sealed, long-term water storage solution for a stationary vehicle, a dedicated stainless steel or opaque, UV-resistant tank is a more appropriate choice. This product is best used for water that will be consumed within a few days of filling.

The lack of a permanent, sealed spout also means that the container is not ideal for gravity-fed systems that require a continuous, leak-proof connection. The removable cap is designed for manual filling and pouring, not for integration into a complex plumbing system. Users should be aware that this can is a portable storage solution, not a permanent fixture for a motorhome’s water system.

UV Degradation and Material Limitations

The white plastic material is chosen for its visibility and ease of cleaning, but it is not UV-stabilized. Prolonged exposure to sunlight can cause the plastic to become brittle and crack, particularly at stress points such as the handles and cap threads. This is a critical limitation for users who leave their vehicles in open, sunny locations for extended periods.

To mitigate this risk, users should store the cans in a shaded area or cover them with a protective tarp when not in use. This simple step can significantly extend the lifespan of the container and prevent premature failure. However, it is important to note that even with protection, plastic containers are not as durable as metal alternatives for long-term storage.

Off-Gassing and Water Quality

Over time, plastic containers can release small amounts of chemicals into the stored water, a process known as off-gassing. This is more pronounced in containers that have been exposed to heat or sunlight, as these conditions accelerate the chemical breakdown of the plastic. For users who are sensitive to taste or odor, this can be a significant concern.

To minimize off-gassing, it is recommended to use the water within a few days of filling the container. If the water has a plastic taste, it may be a sign that the container is not suitable for long-term storage. In such cases, users should consider switching to a different material or using the container for non-potable purposes, such as washing or fuel storage.

Fuel vs. Water: Managing the Risk of Cross-Contamination

One of the key features of this product is its dual-purpose design, allowing it to be used for both water and fuel. However, this versatility comes with a significant risk of cross-contamination if not managed carefully. The light white plastic is not color-coded to distinguish between water and fuel, which can lead to serious safety hazards if a user mistakenly pours fuel into a water container or vice versa.

Unlike single-purpose fuel cans that are often color-coded (red for petrol, yellow for diesel), this product relies entirely on user diligence to ensure correct usage. Users must clearly label each can with its intended contents and use separate containers for water and fuel to avoid any risk of contamination. This is a critical safety protocol that must be followed to prevent engine damage or health risks.

The material is durable enough to withstand the chemical properties of petrol and diesel, but it is not designed for long-term fuel storage. Fuel can degrade over time, and the plastic may absorb some of the chemical compounds, leading to potential leaks or material degradation. Users should only use this can for short-term fuel storage and ensure it is thoroughly cleaned before switching to water storage.

Labeling and Color-Coding Protocols

Given the lack of inherent color-coding, users must implement a strict labeling system to distinguish between water and fuel containers. This can be achieved by using permanent markers to write “WATER” or “FUEL” on the side of each can, or by using colored tape to create a visual distinction. This simple step can prevent serious accidents and ensure that the correct liquid is used for the intended purpose.

It is also recommended to use separate caps for water and fuel, if possible, to further reduce the risk of cross-contamination. If the same cap is used for both, it must be thoroughly cleaned before switching between liquids. This is a critical step that should not be overlooked, as even small amounts of fuel in a water container can be harmful.

Cleaning and Material Safety

Switching between water and fuel requires a thorough cleaning process to remove any residual chemicals. The plastic material is durable, but it can retain odors and chemical residues if not cleaned properly. Users should wash the can with warm soapy water and rinse it thoroughly before using it for water storage.

It is important to note that while the plastic is suitable for short-term fuel storage, it is not designed for long-term exposure to fuel. Prolonged contact with fuel can cause the plastic to become brittle and crack, leading to leaks and potential environmental hazards. Users should limit the duration of fuel storage and ensure the can is inspected regularly for any signs of wear or damage.

Fitting Two 10L Cans into a Compact Caravan Boot or Motorhome Locker

The physical dimensions of the Unibos 10L can make it a practical choice for compact vehicles and motorhomes with limited storage space. Each unit measures 34cm in height, 28cm in width, and 14cm in depth, allowing them to fit into standard UK caravan storage compartments and motorhome lockers. This compact footprint is a significant advantage over larger, single 20-litre containers, which may not fit in tight spaces.

The ergonomic design of the handles and spouts makes it easy to pour liquid in tight spaces, such as a motorhome galley or a small camping table. The top-fill mechanism allows for easy filling without the need for complex spout mechanisms, reducing the risk of spills in confined areas. This design choice makes it a practical choice for users who need to manage their liquid storage in a compact vehicle.

The footprint of the 2 x 10L setup is more flexible than a single 20L container, allowing users to arrange the cans in different configurations to fit their specific vehicle storage constraints. This flexibility is particularly useful for users who need to store other items in their boot or locker, as the cans can be stacked or placed side-by-side to maximize space.

Ergonomic Design for Tight Spaces

The handles on the Unibos 10L can are designed for easy carrying, even when the container is full. The top-fill mechanism allows for easy pouring without the need to tilt the container, reducing the risk of spills in tight spaces. This is a significant advantage over side-mounted spouts, which can be difficult to control in confined areas.

The removable cap allows for easy access when pouring water into jugs or kettles, a feature that is often missing in more rigid fuel containers. This ease of use makes it a practical choice for users who need to prepare hot drinks or wash up at their campsite without the hassle of complex spout mechanisms. The design is user-friendly and intuitive, making it easy to use even in stressful situations.

Footprint Comparison with Single 20L Containers

The 2 x 10L setup offers a more flexible footprint than a single 20L container, allowing users to arrange the cans in different configurations to fit their specific vehicle storage constraints. This flexibility is particularly useful for users who need to store other items in their boot or locker, as the cans can be stacked or placed side-by-side to maximize space.

A single 20L container is often too large to fit in standard UK caravan storage compartments, particularly in older models with smaller lockers. The 2 x 10L setup, on the other hand, can be easily accommodated in most vehicles, making it a more practical choice for a wider range of users. This flexibility is a key advantage of this product, particularly for users who need to manage their liquid storage in a compact vehicle.

Who Should Skip This

This product is not suitable for users who require a permanent, sealed water reservoir for a motorhome or caravan that sits unused for months. The light white plastic is not UV-stabilized and is susceptible to degradation over time, making it unsuitable for long-term static storage. Users who need a durable, long-term storage solution should consider a stainless steel or opaque, UV-resistant tank instead.

It is also not ideal for users who need a color-coded fuel can for professional or commercial use. The lack of inherent color-coding requires strict user diligence to prevent cross-contamination, which may not be feasible in high-volume or professional settings. Users who need a reliable, color-coded fuel container should look for a dedicated fuel can with distinct color coding.

Finally, this product is not suitable for users who require a gravity-fed water system for their motorhome or caravan. The removable cap is designed for manual filling and pouring, not for integration into a complex plumbing system. Users who need a continuous, leak-proof connection for a gravity-fed system should consider a dedicated water tank with a permanent spout.

Final Verdict

The Unibos 2 x 10 litre jerry can is a practical and versatile solution for short-duration camping trips and festival attendees who need flexible, portable water or fuel storage. Its dual-unit configuration offers a distinct advantage in weight distribution and storage flexibility, making it a suitable choice for compact vehicles and motorhomes. However, users should be aware of its limitations for long-term static storage and the need for strict labeling to prevent cross-contamination. For those who need a reliable, portable liquid storage solution for short trips, this product offers a solid balance of capacity, durability, and ease of use.
