Comparison Black&Decker ASI400 vs Black&Decker BDCINF18N-QS

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.

The presence or absence of a battery supplied with the corresponding compressor. This item may also indicate a built-in battery.

Models with a removable battery are usually produced for a specific battery platform (see the corresponding paragraph). The advantage of this solution is obvious: first of all, it allows you to use the same battery both to operate the compressor and for another power tool supporting a similar battery platform. For normal full operation of the device right out of the box, 1 battery is enough. The option without a battery becomes relevant if the customer wants to choose a power source separately, or when such a source is already on the household.

Many compressors are equipped with a built-in battery. This design saves the customer from fiddling with a separate charger, but does not allow you to quickly replace a dead battery with a fresh one - the only option is charging, which requires a power source and takes some time. However, models with a built-in battery are often more compact, which benefits them exclusively for future use.

The name of the battery platform supported by the device. A single battery platform is used to combine various power tools of the same brand (screwdriver, grinder, circular saw, etc.) into one line. Devices belonging to the same platform use interchangeable batteries and chargers. Thanks to this, for example, there is no need to select a battery for each individual model, because one battery purchased as a spare can be used in various power tools, depending on the situation or as needed. Batteries of the same platform mainly differ from each other except in capacity.

The nominal battery voltage for which the cordless tool is designed.

Manufacturers select battery voltage taking into account the operating characteristics and the power supply required to achieve these characteristics. In practice, this means that most often you can not pay attention to this parameter at all when choosing. The only exceptions are some specific situations - for example, if the “household” already has a battery from the same company and you want to evaluate its compatibility with the selected model, if the selected tool comes without a battery and you want to immediately order a power source for it, or for accurate comparison of batteries by capacity. But after purchase, voltage data can also be useful for searching for chargers in addition to or as a replacement for the “native” charger.

Models of batteries compatible with the device.

When choosing a tool, this information is relevant mainly for models without a battery included. For devices supplied with batteries, the battery model is more of a reference value - it is indicated mainly “for the future” if a spare or replacement battery is needed. However, this data can also be useful during the selection process - for example, to assess compatibility with a battery you already have on your household, or to find detailed data on compatible batteries and determine how well they meet your requirements.
