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

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

This is a perfect RPi power supply and the on/off switch is something the RPi has needed for a long time (in my opinion). This is a great value for the price.

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.

Not the cheapest but the switch is nice and great to know it supplies the power the 4 needs

Just wish the USB cable was detachable at both ends. At least it finally solved my power warnings.

This power supply has more wattage than standard power supply. The convenience of the bundled power switch alone makes it worth the price. And if you are running accessories such as a 5-volt fan and a M.2 SATA drive, then I recommend this power supply over the standard one.

I used this for my 4b pi

Really like the power switch. It’s the only inline usb-c one I’ve found

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.

What can I say... It delivers the power the raspberry pi4 needs.
