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

Works as advertised!

I recently got the version with Pi switch and I am glad I did. Works perfectly with my Pi4 and an external WD USB hard drive. I also connect an iFi Zen DAC, but use a separate iFi power supply for the DAC. So far so good. I can recommend this power supply for the RP4 with external hard drive connected.

I was using an underrated power supply to power my Raspberry Pi 4 running Home Assistant, with a couple of usb gateways plugged in, and frequently getting low power readings that seemed to crash my Home Assistant. I read about this power supply, so I tried it. It does seem to have solved my under-power problems. The reason I give it 4 stars is the price. This is a very pricey power supply. So, if you need it, I would recommend, but if not, just stick to the lower price options.

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 :)

Did not work to power my raspberry pi4 4GB. Returned this right away....

The power supply works very well. I no longer receive the low power indicator from the Raspberry Pi desktop. My only negative comment is that the cable is a bit stiff. I would recommend this power supply and would purchase again.

Convenient, like all wall power supplies.

I had what I thought was a good quality USB-C charger that claimed 3 watts output at 5 volts, which should be fine for Raspberry Pi 4, but I was getting low voltage warnings with it.

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.

Good quality. Good price. Voltage within Raspberry Pi specs. Some are not. I have 3 of them. Add a USB-C to micro-USB converter - and it works great for Raspberry Pi 3B+ as well !!
