Dobrý den, řeším možnost alternativního nabíjení na cestách, kde není k dispozici 230V. Použití měniče 12/230V předem zavrhuji. Rád bych použil zásuvku zapalovače v automobilu, autobaterii jako takovou, měnič z 12 na 19-20V, nebo powerbanku s výstupem 19-20V. Měnič mám suprový kilowattový, problém je tedy ten napájecí konektor u notebooku. Jenže jak zjišťuji, konektor má uprostřed třetí vývod. Musí být ten třetí vývod zapojený? Opravdu se NB neobejde bez dvou napájecích vodičů? Nebo se prodává něco speciálního? Oni jsou schopni udělat z halířového řešení řešení za tisíce, a to se mi nelíbí. Děkuji.
