Building a 24v system so I want to maximize 24v devices and minimize 12v/110v ones. Shopping. I'm seeing sockets (cigarette lighters) that say they are compatible with 12v/24v and have 24v USB ports. QUESTION: Can I SAFELY plug normal (i.e.12v) devices into the socket and 5v (phones) into the USB port ???
