for Raspberry Pi 5 Power Supply 27W USB-C GaN Power Charger Output 5.1V/5A, 9V/3A, 12V/2.25A, 15V/1.8A Replacement for Official Power Adapter-GaN PD 27W

Well so far I haven't seen a low power warning on my Pi 5. But...I'm also running a headless Home Assistant install which doesn't really tell me if that happens. I'm using an external SSD via USB 3.0 adapter.As a side note, Raspberry Pi (and other Mini-PCs) seems to think it was a good idea to power their boards via a USB port. Unfortunately every new version seems to require more and more power. Personally I think the use of the USB port to push 25W of power through was never it's intention. It makes these power supplies more and more expensive in order to accommodate it. At some point I'll look into directly powering it through the GPIO pins but until then...we're forced to purchase higher priced power supplies now. So even though this is rather expensive...it seems to be a necessary part of a RPi 5 now.I did try it on a RPi4 with 4" DSI TFT Touchscreen using a USB C to USB Micro adapter and would occasionally get the low power warning. But...in it's defense I think the problem was the adapter causing a power restriction since like I said above, the RPi5 doesn't seem to have any issues with it.Anyway, the power supply works for a RPi5. Is priced around what RPi5 power supplies are going for. The quality seems reasonable. The cord seems nice and thick and long. Depending on your peripherals, it should cover quite a bit of power requirements if it can indeed push out 27W of power.

This being my first time owning a PI, I was caught off guard at the immense power it takes to run one, I originally used a quality cell charger I had to attempt to run it which wasn't enough, so I ordered a newer USB cable which provided enough to boot but not finish installation, so I ordered another charging box this time it was enough power to finish installation of PIOS however was not enough to maintain current to run any programs.That was until I purchased this product which fulfilled it's promise and has provided a stable running environment to date.

This power supply was tested with Raspberry Pi 5 and an official Raspberry Pi cooler. The initial boot-up was fine, but at the second boot-up (with temperature 58 C, fan operational, plus the USB speaker attached)the dreaded "insufficient 5A current" warning popped up.So this is a quality power supply usable with Raspberry Pi 5 but as a replacement for the official Raspberry Pi 27 W power supply - not quite.

We got this for a Raspberry PI5. It works perfect with it even at full use. It doesn't spark when plugging it in and doesn't get more than warm. Seems to be built for it's rated output and safe. At this price point I would buy it again.

If you use an older power supply meant for a Pi 4, you get a warning message about limited current avaiablity. With this power supply, you don’t get that warning since it complies with the requirements for the Pi 5. If you look at the label on the case, it indicates that 5V at 5A is available which is what the Pi 5 needs. Also notice the ETL safety mark which means it meets safety standards. The box within a box mark means it is double insulated and doesn’t need a grounded outlet. So I am pleased with this power supply.

From what I can tell its running fine. I have a USB-C power meter I threw this on just to see how its running, and while I have the RPi mining its putting out a little over 5v 1a. I've also run it while running RetroPie and works fine there. Other chargers I've gotten complains when starting up the RPi that its not receiving enough power and it limits ability.

The replacement Raspberry Pi 5 power supplies are a real step up when compared to the power supplies offered for the Raspberry Pi 4. This power supply has current compensation of the output voltage that eliminates the voltage falloff that you see in the older Raspberry Pi 4 supplies. They also offer quick charge protocols that can output voltage at 9, 12, and 15 volts.This power supply had an output voltage of 5.17V at 5A when tested using a constant current load.

Works just as well as the official power supply, but at a more reasonable cost.
