Mounting variants for USB sockets: adapter for cigarette lighter, for permanent installation, for surface mounting and for switchboards with rectangular cutouts (from left)
Whether smartphone, camera or mini quadrocopter: The USB socket as a charging current source is now a widely used standard. Most manufacturers still supply a plug-in power supply for use at home, which of course fits optionally. In the case of very simple devices such as toys, the USB socket of the computer is sometimes referred to as the charging station.
But what if neither a socket, a notebook or a power bank with a sufficient battery level is within reach - that is, on the way on the ship? We examined adapter plugs and built-in sockets that provide a USB charging socket directly from the 12 volts on board. We have mainly concentrated on products that you can find at ship suppliers and preferably on built-in solutions instead of flying adapters.
