Reddit reviews LoveRPi MicroUSB Push On Off Power Switch Cable for Raspberry Pi (Female to Male)

Plugging it in turns it on. That's about it. You can get a power switch if you'd like to make is easier though. I've got a similar one to this, https://www.amazon.com/LoveRPi-MicroUSB-Switch-Raspberry-Female/dp/B018BFWLRU. Works fine for me but might not provide enough power for some rigs.

Also, some folks just keep their pi on all the time which negates the need to power it up.

Yeah, here's the link to the switches I use:

You can turn your Pi on/off without unplugging the power cord if you have this:

If you need a physical power switch after shutting it down: http://www.amazon.com/LoveRPi-MicroUSB-Extension-Button-Raspberry/dp/B018BFWLRU/
You can use your existing power supplies.

It is highly recommended to go through the shutdown processes everytime you want to turn the device off to avoid SD card corruption. If you want to add a switch, so you dont have to unplug the cable every time you turn if off you can look at something like this:

Not sure where you are getting your 18650's from.... laptop batteries are a good place to harvest. But gotta check them. Most laptop batteries that "die" only have one cell that has gone bad. And you can get 18650 cases that hold 8x18650's pretty inexpensive on amazon and the like and that should power a pi zero for days. I've had one running on a 2x with motioneyeos for >24 hours. ymmv.

nice switch. always new pi stuff to learn just started myself ended up getting this http://www.amazon.com/LoveRPi-MicroUSB-Extension-Button-Raspberry/dp/B018BFWLRU?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00

Had a another thought... How are you turning the pi back on? It sounds like you have power always on to the pi... So do you have to unplug/plug it back in? If so you should remove power from the Pi's micro USB port after your script has run... Or did you install a similar product to the one I posted? That product has a chip built into the board that shuts power off until you press the power switch...

Maybe you could get an in line power switch like this one:

And once your shutdown script shuts the pi off, power it off with the in line switch... Then when you want it back on just push the button on the in line switch.

in line with the supply i already had. Works well and i haven't had any power issues with it either.

I shut down the computer every time before switching this off. But that is common practice for all my PCs/consoles/single board computers. But this is the exact one I use.

Once again this IS the Raspberry Pi 3 version NOT the Raspberry Pi 4 which uses USB C. I don’t have the latest Raspberry Pi and cannot comment on what to use. I assume USB C also has something like this but I have not researched that option.

This is the switch I purchased for my Pi. I like it a lot and it is inexpensive, comparatively.

Yep CanaKit is awesome, do yourself a favor and add this to the cart as well. https://www.amazon.com/gp/product/B018BFWLRU/ref=oh_aui_detailpage_o00_s02?ie=UTF8&psc=1
Stops the wear and tear for the power jack.

Mine was triggering off a logitech unifying receiver and wifi running OpenElec with a 2.0A USB charger. That said, it's a charger not a supply.

That said, I bought a Canakit 2.5A power supply and this switch:

I haven't experienced the low power/voltage warnings on this setup.

I use one of these

I see. I believe I'd have to use a similar product, since the power supply i'm using does not have a removable micro-usb fiting
