CanaKit 45W USB-C Power Supply with PD for Raspberry Pi 5 (27W @ 5A)

Solid chargers, I think I've bought 10 of these between work and home. Maybe not the cheapest, but they're worth the cost.

Update 2: All issues resolved without any fault of the power supply. So it goes up to 5 stars. It works perfectly (even when my other gear doesn’t). :) Update: Well I think there might have been a pi configuration error contributing to the issue I was having. I’m not convinced it is the power supply at this point, so even though I’m hamstrung since getting it, I think this power supply is working exactly as intended. Original: I finally got a dedicated power supply so I could run my Pi5 (16GB) without using power from my MBPs UBC output. But this supply doesn’t seem to meeting the requirements of the Pi. There is some LED blinking on the Pi, but I can’t get the pi to actually boot unless I plug it back in to my laptop. Anyone else having a similar issue? I’ll try to update it I figure it out, but my best guess is that it isn’t negotiating thew handshake, and is operating at an alternative power profile (9V/3A, 12V/3A, 15V/3A, or 20V/2.25A) instead of the intended 5.1V/5A the pi needs. For now, it is hard to give any star for a product that isn’t able to do anything for me. I’ve had good experiences with CanaKit in the past, so it’s disappointing to have this failure.

I cannot find my old review of this power supply unit, and I wish I could because I would have provided a good edit. I apologize for the previous review. It wasn't technically a BAD review, but it wasn't as good as it could be because of the issue I will get to. I purchased this because I was unaware of how power hungry the Pi5 is, and I was getting the under current warning every time I would boot up. Yes, the Pi5 will technically run with a Pi4 power supply, but you won't enjoy the full power of the Pi5. So purchasing a PSU like the one from Canakit is the way to go. Anyway, I bought this so I could feed the hungry beast of a Pi, unboxed it, plugged it in with high expectations that it would run fine and give me no warnings. But my hopes were dashed as soon as I got to my home screen and saw the warning in the upper right hand corner...mocking me. So, the battle was on. At first I thought it was the PSU not being able to quite deliver enough of the angry pixies and stopped trying to figure it out at that point. This was when I left a review stating that it wasn't quite up to Pi5 expectations, but that it would be good for a Pi4 (and yes, it WOULD be good for the Pi4 as well). I ordered a new, Pi5 PSU direct from one of the other distributors and again, with same expectations in mind, plugged it in and was relieved to see no warning. However, that did not last long. I started getting the error again. After digging around, I found out what the issue was. You have to add a line to the config.txt file and rpi-eeprom-config file to tell the Pi5 that it is indeed powered by a compliant PSU. That line is "PSU_MAX_CURRENT=5000". Once you do that, and reboot, you will be pleased to see no more warning. I have never been disappointed by Canakit's offerings, and will always recommend them to people if they are looking for Pi related hardware. I sincerely apologize for my previous review. This is indeed a good product, and the truth is, it was PEBKAC all along, and I just needed to dig some more.

This is a solid power supply. It works with the Pi as advertised, you can charge most USB-C chargeable things with it (e.g. your phone, laptop, etc) although I usually still recommend getting a dedicated power brick with a separate high-speed USB cable, as it can eliminate the chance of the cable fraying causing the entire thing to become useless. This does feel high quality though. It doesn't seem like it'll have any issues with fraying/splitting any time soon. It can get a little hot, but absolutely nothing of concern.

The CanaKit 45W USB power supply works great with my Raspberry Pi 5 and 4, with no issues! But, sigh, CanaKit wants additional money for a switch with an LED. Would have liked folding prongs, would have liked a power LED-- in the base model/config. A switch probably is asking for too much but this is not the least expensive power supply around for Raspberry Pi.
