The steam power supplied by the iron in boost mode.
The steam power is the amount of steam the iron produces per minute. See above for more information on the general meaning of this parameter. And the steam boost mode is a mode of enhanced steaming, when the iron practically “shoots” with a boost of steam; "shot" is usually made by pressing a special button. Steam boost allows you to achieve an intense effect that is not available with conventional steaming; such an impact can be useful, for example, to smooth out heavily rumpled fabrics that would be difficult to deal with in other ways.
A steam boost of 100 g/min or more is said to be sufficient to handle most tough and "unruly" materials. And
models with a powerful steam boost from 200 g/min will definitely not leave even the most dense fabric rumpled. However, there are models with more modest indicators — they are quite suitable for those who need an iron for ordinary household ironing. Moreover, high power, usually, affects the cost. Do not forget about irons with a steam generator, where the performance values are higher, since the purpose of the iron is slightly different.
The volume of the water tank installed in the iron.
The water from this container is used to generate steam when steaming fabrics. In modern models of irons, the tanks are made of transparent materials and are provided with a lid at the opening through which water is poured. As for capacity, a large volume, on the one hand, allows you to work longer without refilling, on the other hand, it significantly makes the entire device heavier. Therefore, in classic models, where the tank is located on the iron itself, the capacity is usually small — about 80 ml for travel and 300 ml for household models. But there are also
irons with a large water tank, in which the volume can reach 500 ml. But for advanced steam generators and ironing systems (see "Type"), the tank is made separately, and in such cases its volume can be 1 L, and for
models with a large tank, figures of more than 1.5 L are typical.
