Přestal fungovat po několika hodinách provozu s Raspberry Pi 1 B+.

Raspberry 2 stále hlásí podpětí, což se u originálu nestává. Kratší kabel.

Na napájení desek jako Esp32 a esp8266 ideální . Bohužel, raspberry pi model 3 B+ hlásí nedostatečný výkon, takže nesprávně funguje. Délka kabelu by také mohla být větší.

Tento zdroj je nekvalitní... Je to v podstatě přeprodej z aliexpress a ten zdroj uvnitř vypadá katastrofálně... šetřilo se na čem dalo. na napájení ESP je to ok
