Comparison Dometic Waeco CoolFreeze CF-40 vs Dometic Waeco CoolFreeze CF-35

The volume of the working chamber of the car refrigerator. The larger the volume, the more products can be loaded into the unit at a time. When choosing according to this parameter, it makes sense to select a model with a margin, because it is not recommended to load products too tightly — this adversely affects the quality of the device. On the other hand, note that the volumetric container and dimensions will have the appropriate ones.

This parameter determines how many degrees the refrigerator is able to cool the product loaded into it relative to the ambient temperature. Let's say the maximum cooling for a particular refrigerator model is 20°C; at an air temperature of +30°C, a product with the same temperature is loaded into it. Thus, the final temperature of the product will be 30 – 20 = +10 °C. In addition, it should be noted that the final temperature cannot be lower than the minimum cooling temperature (see Minimum cooling temperature)

The power consumed by the refrigerator when operating in cooling mode. The greater this power, the more performant the refrigerator is, usually, and the less time it takes to cool the product. On the other hand, note that more power means more power consumption — which can be critical, for example, during long-term operation from a car battery (that is, when the car engine is turned off).

— USB for charging gadgets. A standard USB connector from which you can charge a smartphone or other gadget. Note that this function only works if the refrigerator is connected to the mains — car refrigerators do not provide their own batteries, and without an external power source, energy will not be supplied to the USB port.

— Smartphone control. The ability to control the unit from a smartphone or other gadget, usually through a special application. The gadget itself is connected directly wirelessly via Wi-Fi or Bluetooth. This feature provides a number of conveniences. Firstly, it allows you to control the operation of the refrigerator from a distance. Secondly, the application on a smartphone is often more convenient and intuitive than the unit's own control panel. Thirdly, the gadget can receive various notifications from the refrigerator: set settings, current status, notifications about problems, etc. At the same time, control from a smartphone is expensive, which is why it is quite rare, mainly in fairly advanced models.

— Built-in fan. The presence of a fan in the working chamber of the refrigerator. Due to this function, improved air circulation inside the chamber is provided, which contributes to better and more uniform cooling of loaded products.

— Discharge battery protection. An car refrigerato...r with this function, when operating from a car battery (with the engine turned off), constantly monitors the state of the battery. If the charge drops to a critical level, the unit “takes action”: it turns off automatically or gives a signal about the need to turn off. This avoids the complete discharge of the battery and unpleasant situations such as the need to start the engine “from the pusher”.

— Internal illumination. The presence of internal lighting in the working chamber of the refrigerator. This makes it easier to use it in low light conditions — even in complete darkness outside, the contents of the camera can be easily seen.

— Removable cover. Possibility to remove the refrigerator cover from the main container. The meaning and features of this function may be different. So, in some models, the cover is removed only in order to make it easier to get to the contents and to make the working chamber easier to wash / clean. In others, it may be possible to choose the side in which the lid will recline. And some units with this function are equipped with two covers at once: one has a power cord and a cooler, when installed, the device functions as a refrigerator, the second is a simple heat-insulating cover that turns an car refrigerator into a thermos.

— Carrying strap (shoulder). A special strap that allows you to carry the device in the manner of a shoulder bag. Actually, most often it is bag models that are equipped with this function (see "Type"). Anyway, such a strap greatly simplifies transportation: it is more convenient to carry a rather weighty refrigerator on your shoulder, in addition, your hands remain free. There are even models that can be carried like regular backpacks.

— Wheels for transportation. The ability to transport car refrigerators in the manner of a trolley is much more convenient than carrying it in your hands or on your shoulder, especially with large volumes and the appropriate weight of the model.
