Rated supply voltage used by the electric compressor (see "Type"); in fact, the types of networks with which the device is compatible.
—
12 V. Standard on-board voltage for passenger cars and similar vehicles such as light trucks and many motorcycle models. 12V compatibility is almost mandatory for modern compressors (only a few models are not capable of operating on this voltage). However, note that the methods of connecting to on-board networks may be different; see "Connection" for details.
—
24 V. A voltage of 24 V is typical for on-board networks of heavy equipment — trucks, buses, etc., as well as some powerful SUVs. In compressors, compatibility with this supply is usually provided in addition to 12 V; Pure 24-volt models are extremely rare.
—
230 V. Connecting to a regular 230 V household outlet. Most often, this option is used as a spare, in addition to 12 V — so that if there is a nearby outlet, the compressor can be powered from it without loading the car battery and without wasting fuel on the on-board generator. However, there are models that use only 230 V — they are designed for stationary use in tyre shops, service stations, etc.
—
Battery. Powered by a removable or built-in battery, it gives you the freedom to use the compressor and allows you to get rid of its hard wire connect
...ion to the on-board car network or a household outlet. However, a dead battery will still have to be charged sooner or later. And in this matter, you can not do without a wired connection. Keep in mind that the battery may not be included in the standard package of some rechargeable autocompressors and will need to be purchased separately.Ways of connection to the power supply provided in the design of the compressor (see "Type").
—
Cigarette lighter. Connection to a standard cigarette lighter socket (or a separate auto socket of the same format). This method is convenient because the compressor does not need to open the hood. On the other hand, cigarette lighters have limits on maximum power, and in different cars (and even in different sockets of the same car), these limits can vary markedly. See Power Consumption for details.
—
Crocodiles. Connect directly to the battery terminals using crocodile clips. This method is somewhat more complicated than working from the cigarette lighter — you need to open the hood and pull the wires to the battery. On the other hand, it allows you to use the power of the on-board network to the fullest without worrying about overloads and the integrity of the fuses, making it suitable for even the most powerful and performant compressors. In addition, the “crocodiles” device can be connected not only to the on-board network, but also to a separate battery; in some cases, this possibility is useful (for example, if the car’s own battery is already running low, but there is a “fresh” battery nearby).
—
Cigarette lighter / "crocodiles". The ability to use any of the connection options described above is optional. This provides convenience and al
...lows you to choose the optimal format of work depending on the situation. For example, for quick pumping of one or two wheels, you can use the cigarette lighter, but for long-term work, food through the “crocodiles” is better suited.
— Fork. Plug for connecting to a regular 230 V socket (see "Power"). It is used in compressors having only this type of supply.
— Cigarette lighter / plug. Available on both 12V and 230 V models; for the first, a cigarette lighter is used, for the second, a plug.
— Cable (to the battery). Connection directly to the battery using cables with flat terminals, which are clamped into the battery terminals when connected. This design provides a tighter contact than the "crocodiles" described above, but is less convenient when connecting and disconnecting the compressor.
