“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!”
“Does the job - rather than yanking out the USB power lead or plug. Has a nice LED showing it is powered on. Beware this works for Pi but not other USB-C cables / devices. Great price too.”
