CanaKit 3.5A Raspberry Pi 4 Power Supply with PiSwitch (USB-C)

Nothing special to say. I can just trust CanaKit for quality

Nice having an on/off switch instead of pulling the power cable and reinstalling same to power cycle the processor.

Works as advertised!

Power supply works great where others have failed - powering an external USB drive + wireless keyboard dongle and driving a 4K display on my 4GB Pi 4. The power switch with LED indicator is awesome - you can tell when power is delivered and can power off/on with a button. Did not realize how nice that was until I got this :)

Started getting undervoltage warnings on my Pi 4 after only a few months of use. Replaced the power supply with this and the warnings are gone. Recommended.

Happily supplies power to my octoprint setup that consists of a webcam, touchscreen and fan. Having a dedicated power switch is also a nice addition!

Extremely happy with this purchase. This combination of power supply and power switch works perfectly with my Raspberry Pi 4. After you have fully shutdown the operating system by using the menu button, or the appropriate command in the terminal, simply press the on/off button on the Pi Switch to turn off the power. When youre ready to use RPi 4 again, simply press the on/off switch again to boot up the Pi. No more pulling out the cord or pushing it back in to power RPi 4 on or off. Excellent product!

Exactly what I expected, but that is because I already have two of these Canakit power supplies.

It can be nice to leave your Raspberry Pi plugged in and just turn the switch on and off as desired. I was surprised that the switch is an add-on unit to the power supply, but I guess that adds flexibility.
