eu stiu ca hertz e firma serioasa
daca e sa o luam matematica ar veni asa: sigurante 2 x 25A (50A)
14.4V * 50A = 720W
cel mai sigur clasa de functionare este AB, deci randamentul este de aprox 60%, deci 60% din 720W vine aprox 432W ( 2*216W si producatorul o da de 2 x 190W in punte) , deci puterea declarata de producator este reala

eu am aceeasi parere ca a colegului. hertz e marca destul de buna poti garanta ca are cifre si masuratori reale
