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

Works as expected.

I purchased two Raspberry Pi 4s a while back, along with 18W chargers. I would often get the lighting bolt indicator for low power... Many chargers will negotiate higher power for charging, but will max out at 2A without this negotiation.

It works just great boxing was a little damaged

Seems well built. Plugs in firmly to my Raspberry Pi 4b (bought another power supply at the same time & other one makes intermittent contact). Good wire insulation. Transformer is cool to the touch running unit for 24 hours.

I prefer this power supply to the official Raspberry Pi power supply for the Pi 4. I have had trouble with the official power supply if you turn on the AC power with the Raspberry Pi attached. When I do, the Pi 4 does not boot properly. I have to disconnect the official power supply from the Pi, allow the power supply to come up, and then plug the Raspberry Pi 4 into the power supply. I do not like connecting and disconnecting the USB-C connector on the Pi repeatedly, as it may be prone to damage.

This does the job. No low supply warnings. Good for the price.

Just what I needed. Works as designed. Design for the raspberry pi 4 and specs are delivered as promised

I built a couple nas boxes using pi4s. Some are using 4 bay external hard drive enclosures, which come with their own beefy power supply and I printed an adapter and bought an SATA power cable extension so that I could tap the 5v from there. Those boxes never get throttled.

Solid power supply for the Raspberry Pi 4! CanaKit delivers again. I got exactly what I expected given my experience with their products. Good quality and it just works!

works as expected for my Pi 4. in retrospect, maybe I should have got a power supply with on/off switch.
