Dobrý den, u tohoto výrobku je uveden výkon 25W, přičemž je napájen z USB. Na stránkách výrobce jsem se dále dočetl, že pracovní napětí je vskutku 5V (nejedná se tedy o větší napájecí napětí až 20V, které poskytuje USB C). Z toho všeho mi tedy vychází, že proud tekoucí celou soustavou musí odpovídat 5A, což mi přijde nereálné. Navíc výrobce udává odebíraný proud 1A, který s napětím 5V dohromady dává výkon 5W, ne 25W. Mohl bych tedy požádat o nějaké objasnění?
