“Bought this for the Pico but alas the Pico has a different connector. This fits the Pi fine so I'm using it as an extender cable. Confusing that ON is a red led rather than green as switching it 'on' switched the Pi off, if you see what I mean.”
“I think this is a must for a raspberry pi, just means you can easily power it off without having to disconnect the power cable, or flick the plug off.”
“I have one Raspberry Pi connected to a power source that does not have a switch at the 3-pin wall socket which provides the power, so this makes it very easy to be able to switch the Pi on and off without having to pull the plug out of the wall socket each time. Since it also has a red LED, it is also easy to see at a glance when it is switched on. A great addition to that particular Raspberry Pi set up.”
