To máte zapotřebí prodávat takové šunty? Rozdělávali jste někdy zrovna tuto USB nabíječku? Na PCB této nabíječky není prakticky žádná oddělovací izolační dráha mezi nízko- a vysokonapěťovou částí. Každá USB nabíječka by měla mezi USB portem a napájecím kolíkem vydržet 3,5 kV(!), což tato nevydrží ani omylem. Navíc je silně poddimenzovaná, 2A nedá ani omylem - má problém dát 1A. Jestli chce někdo doma vyhořet, tak tento pazgnecht je naprosto ideální kandidát na příčinu. Rozlišení obou USB portů rozdílnými nápisy užití je naprosto irelevantní, je to ze stejného dvojUSB, ke kterému vedou pouze 2 drátky. Ta USB nabíječka má cenu pouze 1 USD a navíc bych ji neměl odvahu nechávat nikde trvale připnutou k síti.
