The presence in the refrigerator of separate zones for storing products, separated by a stationary dense wall of a non-removable structure. The vast majority of car refrigerators have a
single-chamber layout, however, there are also
two-chamber models, which is extremely convenient for sorting products.
—
USB for charging gadgets. A standard USB port that can be used to charge a smartphone or other gadget. Note that this function only works if the refrigerator is connected to the power grid — car refrigerators do not have their own batteries, and without an external power source, no energy will 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 function provides a number of conveniences. Firstly, it allows you to control the operation of the refrigerator from a distance. Secondly, the application on the smartphone is often more convenient and visual than the unit's own control panel. Thirdly, the gadget can receive various notifications from the refrigerator: settings, current status, notifications about malfunctions, etc. At the same time, control from a smartphone is not cheap, 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 ensured, which contributes to better and more uniform cooling of the loaded products.
—
Battery discharge protection. A car refrigerato
...r with this function constantly monitors the battery condition when operating from a car battery (with the engine off). If the charge drops to a critical level, the unit “takes action”: it switches off automatically or signals the need to switch off. This allows you to avoid a complete battery discharge and unpleasant situations such as the need to start the engine “by pushing”.
— Interior lighting. The presence of internal lighting in the working chamber of the refrigerator. This makes it easier to use in low-light conditions — even in complete darkness outside, the contents of the chamber can be easily seen.
— Removable lid. The ability 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 to make it easier to get to the contents and to make it easier to wash/clean the working chamber. In others, it may be possible to choose the side to which the cover will be folded. And some units with this function are equipped with two lids 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 the car refrigerator into a thermos.
— Carrying strap (on the shoulder). Special strap that allows you to carry the device like shoulder bag. In fact, this function is most often equipped with bag models (see "Type"). In any case, such a strap significantly simplifies transportation: it is more convenient to carry a fairly heavy refrigerator on your shoulder, and your hands remain free. There are even models that can be carried like regular backpacks.
— Transportation wheels. The ability to transport car refrigerators like a cart is much more convenient than carrying them in your hands or on your shoulder, especially with large volumes and the corresponding weight of the model.
