Old and busted: Power-over-ethernet. New hotness: powering your switch from your router's USB port using a home-soldered USB-A -> barrel jack adapter cable.

Photograph of two network devices. To the left is a Mikrotik access point, powered through a black cable coming in from below. To the right is a Netgear ethernet switch. The two devices are connected with a yellow ethernet cable, and the Netgear switch is also connected with another ethernet cable which leaves the frame at the bottom. The Mikrotik is powered through a black cable coming in from below. On the top side of the Mikrotik, an USB-A cable is plugged which plugs into the back side of the Netgear switch, acting as power source.
