Glossary
Efficiency
Efficiency of the autoinverter.
Efficiency is the ratio (in percent) between the amount of energy that the device delivers to the load and the amount that it consumes from the vehicle's on-board network. Accordingly, the higher this indicator, the more efficient the work and the less loss during conversion. In fact, this means that, other things being equal, a device with a higher efficiency will allow the load to run longer on battery power; this is especially important at high power consumption.
In modern auto inverters, efficiency values of 80 – 85% are considered average, 90% or more are good.

Low battery alarm
The presence in the auto inverter of the low battery alert function to which the device is connected.
This function significantly reduces the risk of “landing” the car battery through the use of an inverter and at the same time eliminates the need to manually monitor the battery status. The alarm, usually, reacts to the voltage at the input: with a significant decrease, indicating a deep discharge, the device gives a warning signal. Many models also have the function of automatic shutdown some time after the alert is triggered (by timer or when the voltage drops to the maximum allowable). The sensitivity threshold is usually adjusted in such a way that after the alarm is triggered and the inverter is turned off, the battery is still able to start the car engine.

Screen
The presence of its own display in the design of the auto-inverter.
The display allows you to display various additional information: input and output voltage, load power consumption, battery status, malfunction messages, etc. In modern auto-inverters, usually, the simplest monochrome LCD screens are used — they are inexpensive, and their capabilities are quite enough for the information described.

Dimensions
General dimensions of the autoinverter.
In modern cars (especially passenger cars), usually, there is not much space for installing additional equipment. This parameter allows you to estimate the space required to place the inverter, make sure that the selected device fits into the “footprint”, and, if necessary, choose another location or another model. At the same time, it must be remembered that for many auto-inverters a certain margin is needed in place — for the normal operation of the cooling system; this margin is usually specified in the detailed documentation.
