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

I've tried multiple power solutions for my Raspberries but none give the results of individual power supplies designed specifically for the task. I run four Pis in a UCTRONICS rack mount, each with an SSD drive rather than Micro SD cards. This power supply runs everything I throw at the Pis and never throttles. The 'vcgencmd get_throttled" command always returns "throttled=0x0" regardless of load when using this power supply. Other power supplies and multi-port USB chargers will return other throttled statuses including "throttled=0x500000" which indicates throttling due to undercurrent.My only nitpicks with these chargers are:1) The cables are very stiff and hard to route neatly into my rack mount2) The magnet at the USB end of the cable is very large and interferes with cable routing as well3) The cables are permanently attached to the brick and can't be replaced in case of a short, etc.I highly recommend this power supply and have bought four of them so far and will continue to do so as I expand my Pi fleet. I do wish they would offer a larger power supply that could run multiple Pis to eliminate all the redundant wall bricks.

Works well for powering my PI, cord length is a good size for what i use it for. Seems durable and its a power cable that is easy to use. Is compatible with other Usb devices as well.

Great power supply and USB charger.It was originally bought in 2020 to power a Raspberry Pi 4, but has seen a lot of extra use as a USB-C charger, because the output is up to 3.5A.It is shown in the pic charging a Playstation 5 controller, just one typical example use.The CanaKit power supply is silent to my ears, with no troublesome high pitched whine or any switching noise. Build quality is great, the plastics are solid and the connector itself is also of high quality.It's built well and has stood the test of time. A recommended purchase!

I'm running two of these each powering a Raspberry Pi 4B 8GB in an Argon One case (hence supporting the accessory board and M2 SSD) as well as various USB accessories. Each are running perfectly with no power issues.You may think your Raspberry Pi is running ok with that "rando" USB charger you grabbed out of a drawer but it may be silently screaming. Here is a quick command you can issue that will indicate if your board has detected an undervolt since power-on or return "ok" if not:dmesg | grep -iC 3 "undervoltage detected" || echo "ok"

I recommend only buying this if you're planning on using it exclusively with your Pi4 and never for anything else.If you want a USB-C power supply for a different reason, you may want to consider a different device which can meet all of your needs.I bought this to sometimes power a Raspberry Pi and sometimes charge my phone, depending on where my Pi needs to be at that moment. I'm aware that it's not a QuickCharger, but the power supply that came with my ArgonOne case (with a similar amperage rating) will dump loads of current into my phone and charge it in about an hour, while this thing charges at a crawl. It could be a quirk of my phone, I suppose, or it could be a poorly implemented USB-C interface so that my phone is deliberately limiting itself to micro-USB levels of current (phone screen says "slow charging").I know this power supply is capable of supplying more current because the RPi runs perfectly fine with it, even overclocked. Even so, since it doesn't meet all of my expectations while a different RPi 4 power supply does, I can only give it 4 stars.

It was easy to put together. Handled the heat well. Compatible with raspberry pie 4. Functioned as described. Build solid. Would buy again.

I needed a new power supply for my Raspberry PI, this did the trick!

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.I can leave the CanaKit power supply plugged in to the Pi, and apply the AC power and everything boots up fine. The extra capacity of the Canakit makes all the difference.Highly recommended!
