1 power outlet
Past me is a genius.
I am just about to go on a family holiday. I always try to unplug most of my electronic devices while no one is at the house even it its just for 2 days. But I still want to keep the filter and heater in my fish tank running. I just went to look through my mess of extention cords and power boards that turns my single outlet into everything in my room. And I found that there first power board in the chain has 1 outlet going to another power board and then the other outlets power my fish tank.
Whoever put everything together to be like this is a genius - Which is weird because I don't normally go out of my way to make things easier for my future self.
I just had to unplug one outlet and now my fish tank is the only thing running.
