Selecting a replacement external power supply – what you need to know
Fundamentally, you need to know four basic things when selecting a new power supply for a broken electronics device. The voltage coming from the socket at the wall (Europe/Japan/US), the voltage output, the current, and the type of connector (USB Type-B mini, barrel, USB-C). What most of us don’t know is that there are some […]
