This, although there are means to connect an on/off switch to the Pi (safely shutting down when powering off), if you are concerned with power consumption then removing power to the supply is the best method (obviously after shutting down).
I use a multi-outlet surge protector, but I don't necessarily want to shut everything off. They do make them with individual switches, but those cost a lot more (and I don't really need another surge protector). So I use something similar to this.

Have only had a pi (B+) for a couple of weeks now. I am running Retropie with only a Tankstick arcade controller and wired keyboard connected. I am using a case with a built-in fan. I have not enabled overclocking.
I have not had any issues with the official pi power supply, but that doesn't have a switch. Although I always shutdown the pi through the OS before unplugging, the unplugging/plugging is going to wear on that mini USB connection eventually. And I have to unplug it to power off the fan. Even if I was using a case without a fan (which I won't), I would have to unplug it and plug it back in to power it back up.
And now I am baffled by my inability to find a power cable with a switch that doesn't result in under power errors. I bought the only one carried by Micro Center and that one, unfortunately, does not come with the power supply (the end of the cable is USB). I went through 10+ power supplies in my attempts to get this to work and every one resulted in under power errors.
There are a great many types available through various online retailers, and every one I have seen has at least one review reporting under power errors.
Anybody here with a similar setup that has had success with a power cable with a switch? I am not looking to install a power button on my pi (1: I like the case I have and it will not accommodate one and 2: I am an idiot who barely got this working as it is).
LOL! I have one of those too (for something else).
Yes thats true, but nobody is talking about 'other devices', they're talking about the Raspberry Pi official power supply.gkaiseril wrote: ↑Sun Jul 15, 2018 7:53 pmNot all devices are double imsulated and the ones that are not double insultated are now required to be grounded. Also most building codes require at a minimum to have grounded outlets, unless wotin 15 feet of water and then the outlet needs to be GFCI. It is easier to make one device, switch, that can handle both grounded and non-grounded cords.
With the additional grounding pin the plug-in switch is less likely to fall out. Note that UK plugs always have three pins even if one is made of plastic.
It is. The UK standard required a shutter over the live socket holes, the earth (ground) pin is used to open the shutter. So the earth pin must be present. On moulded "Wall Wart" PSUs that are double insulated, the earth pin can be plastic. On other double insulated appliances, moulded plugs may have a plastic pin, but replacable plugs must have a metal pin.
That is actually quite a good idea. Since you know you really shouldn't do any (Pi related) soldering while the Pi is on, unplugging (rather than just switching off) is a Good Thing, with a positive impact on Mistake Prevention. Especially since you can't then leave the iron hot when you reconnect the Pi, removing the temptation to just reflow that one joint without switching off....
"better" is a vague adjective, but I think, here, it means "give you fewer problems"
See? You've got the wrong pet. Ours can't flip the switches on power strips, even if they did escape their enclosures.
Well, there ya go. I guess everything has an upside.Ours can't flip the switches on power strips, even if they did escape their enclosures.
Actually, it was because of them (well, it was just the one at the time) that I started one of my Pi projects. It started out as just a simple temperature sensor/relay/heater to keep one small room at a reasonable temperature for the spider while we were away for a few days and grew to be a full heating control system for the house
