The amount of current drawn by the compressor during operation. For most models intended for use with passenger cars, this indicator is at the level of 12-14 A. A small current consumption is preferable from the point of view of energy saving, but the performance of the device largely depends on this indicator (see "Performance").
The presence of the function of
bleeding air in the design of the device.
This function is found exclusively in electric compressors (see "Type"). It, in fact, allows you to run the compressor "in the opposite direction" — not for pumping, but for drawing air. This mode can be useful if you need to quickly deflate a large inflatable object — for example, a mattress: manually blowing off often turns out to be a rather long and tedious task, and besides, it is not always possible to effectively remove residual air, while the compressor handles with this without problems.
Usually, for work with bleeding, a special hole is provided on the body, to which the air hose must be rearranged.
