Cooler bags and boxes: everything you need to know about mobile coolers before buying
Cooler bags and boxes are essential accessories for multi-day trips. However, it doesn’t matter which solution you choose. In this article, we’ll show you the key differences between various mobile coolers and help you decide which one is the best choice for truck drivers so that it fully meets your needs.
A good cooler is one of a truck driver’s best companions. It helps keep food fresh during long journeys and ensures that your drinks stay cold and refreshing even in the summer heat. However, to truly enjoy these benefits and avoid unpleasant surprises, it’s important to find the cooler that best suits your needs.
But what options are available, and what factors should you consider when buying a new cooler? In this article, we’ve gathered the most important information that every well-prepared truck driver should know about the use and operation of mobile coolers!
What types of mobile coolers can we choose from?
Just like in any other field, today’s cooler market offers a huge variety. If you’re looking for a reliable, mobile solution, you can choose from many different designs. The differences are not only in size and efficiency but also in the cooling method used.
Passive coolers
Passive coolers do not require a power source. Simply fill them with ice packs or ice cubes, and thanks to their excellent insulation, they can keep food fresh and drinks cold for a long time. High-quality passive coolers can maintain this performance for several days, depending on usage and weather conditions. However, it’s important to note that passive coolers are only suitable for cooling and keeping items fresh. Their temperature cannot be adjusted freely.
Compressor coolers
Compressor coolers are essentially smaller versions of standard household refrigerators. They can lower the internal temperature below 0 oC, making them suitable for freezing, and they can quickly cool down non-pre-cooled items. These coolers operate using complex technology, which makes them slightly more expensive than simpler cooling solutions. In return, they offer outstanding performance and reliability.
They are available in portable and built-in versions, including truck-specific models, as well as units designed for boats and motorhomes. Portable compressor coolers designed for truck drivers are optimized to withstand frequent loading and unloading.
Compressor coolers can differ in both performance and power supply. Some portable models operate only on 12–24 V, while others can also run on 230 V mains power. Before purchasing, it’s important to check whether the chosen model suits your needs and the environment in which you plan to use it.
Thermoelectric coolers
Thermoelectric coolers operate on a completely different principle compared to compressor coolers. Their core is a thermoelectric module built into the casing, which uses the so-called Peltier effect for cooling. Some thermoelectric models can not only cool but also heat, making them suitable for keeping tea, mulled wine, or food warm.
However, it’s important to note that due to their operating principle, thermoelectric coolers cannot reduce the internal temperature arbitrarily below the ambient temperature. Their cooling performance is typically defined by the temperature difference they can achieve. Higher-end models improve efficiency with better insulation and enhanced heat exchange fans.
Thermoelectric coolers have a wide range of applications but are primarily designed to maintain the temperature of pre-cooled food. They are available in various sizes, from 8 to 45 liters, so everyone can find a suitable model. They can also operate effectively even in a tilted position.
Absorption coolers
The biggest advantage of absorption coolers is that they can operate not only on 12 V and 230 V but also on gas. This is why they are extremely popular among campers and truck drivers, as they do not require a constant power source. They can be used practically anywhere, under any conditions. They are available in both portable (box) and built-in (cabinet) versions.
What size cooler should we choose?
The size of the cooler is one of the most important factors to consider alongside performance. The right size depends on your goals and how much space is available in your vehicle. The longer you want to stay independent from shops and the further you plan to travel, the larger and more powerful cooler you will need.
Capacity in liters is a great starting point when choosing the ideal cooler size. But how can we determine at first glance what fits inside a given model? A simple 1.5-liter PET bottle is a useful reference. Most universal portable coolers and boxes should easily accommodate a 1.5-liter bottle in an upright position.
Operating a cooler from a cigarette lighter: is it really dangerous?
Drivers often wonder how much power a high-performance cooler consumes and how to supply it efficiently. Is it possible, for example, to operate a cooler from a cigarette lighter socket?
There is a common misconception that running a mobile cooler from a cigarette lighter is dangerous. This belief stems from the idea that unstable connections can cause the cooler to switch on and off frequently, which may damage the compressor over time. However, this is not entirely true.
A cooler typically draws 4–5 Amps during normal operation, which any properly functioning cigarette lighter socket can handle. This means most mobile coolers can be operated this way, provided the socket is not loose and the connection is stable.
However, it’s important to note that if the cigarette lighter connection becomes loose, the cooler will stop cooling. Frequent switching on and off can indeed reduce the lifespan of the cooler and its compressor. Therefore, a fixed connection is a more efficient, safer, and more economical solution.
How reliable is a battery-powered cooler?
Many people do not have access to a reliable power source on the road or simply want to disconnect from civilization. In such cases, a battery-powered cooler often comes to mind. But how effective are they? How long can a battery last without charging? And are there accessories that can extend usage time?
Modern battery-powered coolers are equipped with compact and efficient compressors, ensuring excellent cooling performance even in high external temperatures. Despite their robust design, they are easy to carry, often resembling suitcases. This makes them an ideal choice for those who prioritize mobility.
A high-quality mobile cooler with a built-in replaceable battery can provide up to 21 hours of operation. It can also be recharged via solar panels, a 12 V socket, or mains power using an adapter. This ensures maximum mobility, efficient operation, and outstanding convenience.
Speaking of convenience, models like the LiON Cooler feature intuitive controls, a user-friendly digital interface, and even integrated Bluetooth connectivity. This allows you to monitor and adjust operation directly from your phone.
Efficient operation: what does ECO mode mean and how can it be used?
For mobile coolers, not only performance but also energy efficiency is important. That’s why high-quality models are equipped with an ECO function. But what exactly does this mean, and how can it be used?
When ECO mode is activated, the control electronics reduce performance, thereby lowering power consumption. If the cooler has a continuous power supply (e.g., from the grid or while driving when the alternator charges the battery), this feature is less significant. However, when stationary and powered only by the battery, it’s advisable to use this “reduced mode.”
Compressor coolers are also equipped with battery protection, meaning they automatically shut off below a certain voltage level to prevent draining the vehicle’s battery completely.
Service support: what happens if a cooler breaks down?
Like any device, a cooler can fail, even if used according to the instructions. The cause can vary, but error codes and explanations provided in the manual can help identify the problem.
Many people wonder what happens if a cooler breaks down. What kind of service support is available? Can certain parts be replaced? The answer largely depends on the type of cooler you choose.
Cheaper models often have limited or difficult access to spare parts. While compressors may be replaceable, control systems can be problematic. However, for brands like Indel B, all parts are replaceable, down to the smallest component. Most high-quality coolers, when used properly, are unlikely to fail, which is also supported by multi-year manufacturer warranties.
Is it only for truck drivers? Who are mobile coolers recommended for?
Portable coolers are extremely useful during travel, which is why they are essential equipment in trucks. However, this doesn’t mean they are only for truck drivers.
A good battery-powered cooler can be perfect for camping families, while a smaller passive cooler is great for the beach. With a wide range of sizes available, virtually anyone can find the ideal model that perfectly suits their needs. In other words, our coolers and boxes are a great choice for anyone who values mobility.
