I'm not sure regarding Power Bar, I'm using a power strip with multiple outlets to plug into and with a surge protector. Here's a link to what they look like. It's inconvenient to plug and unplug from my wall socket behind a desk so I do it this way https://www.webstaurantstore.com/blog/2448/surge-protector-vs-power-strip.html

Mine is plugged into a power strip. I've just been leaving mine on, for the week I've had it. I think it would be fine to turn your router off at night, especially easy with a switch and you'd save on electricity.
