Starter/chargers with built-in compressor

Built-in compressor

— the presence in the device of a built-in compressor for pumping wheels.

This feature is found mainly in boosters. Such models actually combine two devices in one housing, saving the car owner from having to buy a “starter” and a compressor separately. However, note that this feature significantly affects the dimensions and weight of the booster; and if compactness is important to you, it may be more reasonable to buy two separate devices.
