“A really useful addition to the Pi 4 armoury, especially when the 64 bit OS is in beta, and Ubuntu 20.04 is still being shaken down. Good for any power source, including portable. Red LED is good, not too bright, but easy to see.”
“This super little accessory is a very convenient and inexpensive way of adding an on/off switch to a USB-C Power Supply for a Raspberry Pi 4. It is well made, doesn't get in the way, and offers a nice tactile indication of the switch mode - what more can I say - it does just what it says on the tin without any fuss!”
