SunFounder 27W PD Power Supply for Raspberry Pi 5, 5.1V 5A GaN 1.2m 3.6ft USB-C Changer Adapter for Raspberry Pi 5 8G/4G/2G/Raspberry Pi 4/Pironman 5 (ETL Listed)

What can I say, it works, provides enough power, looks good, and is compact.

This little unit is solid, powers my Pi 5 in a Pironman 5 case (so a pi 5, 2 40mm fans, a small oled screen, and an nvme ssd) with a 200mhz overclock without any power related issues. I can't complain.

I liked the fact that it was a power cable.

I needed a new power supply to power my Raspberry Pi 5, since they are picky on power supplies and want an uncommon power input: 5.1V at 5A. You can use a regular power supply that will do around 5V at 3A, but you will likely get a warning and it will limit any power to the USB devices and may throttle the CPU. This SunFounder charger seems to meet these requirements, as I have not seen an error, and it has provided the 5.1V and amperage the Pi has needed. The peak current pull I have seen is about 2A total with an external 2.5" drive connected, but I am sure it can get higher if you need more power. The power supply does not have any whining or other noises coming from it, and seems to work fine. The cable part of the supply is fairly thick to support the higher amperage, so its not the most flexible, but nothing out of the ordinary The charger also supports other USB-c power delivery voltages up to the 27W peak, so you are not limited to only a raspberry pi. It's a charger that kind of sits there and works or it doesn't, and I am happy to say this one works for its purpose. No complaints at a low price.

As much as I love locking one of my USB charger/cable sets to power my Pi's, these purpose built power supplies have really been nice for me. By the time you factor in a good USB-C cable, AND a power brick for it, this power supply is a great value! The biggest annoyance with Pi's is always the Low Voltage warnings from standard phone chargers. With newer USB-C bricks, it seems to be more hit than miss on voltage compatibility compares to the older "standard" USB chargers, but this power supply completely solves that problem. I'm not sure it's really a GaN supply, and I don't have any equipment to verify that functionality, but the power coming out hasn't let me down so I have no complaints. Overall, it's a great value, works great, frees up my other cables/chargers, and I'm a big fan.

Why are the raspberry pi parts soo expensive. I think my rpi 5 will be the last rpi I buy. Not worth the price.

The 27W PD Power Supply for Raspberry Pi 5 is an excellent choice for powering your Raspberry Pi with reliable and efficient performance. It provides a stable 5.1V at 5A, ensuring that the device operates smoothly even under heavy loads. The GaN (Gallium Nitride) technology enhances efficiency, allowing for faster charging and reduced heat generation. The 1.2m (3.6ft) USB-C cable is long enough to provide flexibility in positioning the Raspberry Pi without being too bulky. The compact and lightweight design makes it easy to store or transport, while its robust construction ensures durability. Ideal for powering the Raspberry Pi 5 and other compatible devices, this power supply offers quick, consistent power delivery without any interruptions. Overall, it's a reliable and high-quality accessory for anyone looking to keep their Raspberry Pi powered efficiently.

I have a Raspberry Pi 5 with active cooler and PCIe bottom adapter, so I needed a good power supply that wouldn't trigger the dreaded "Under Current" warning on my Pi. Most USB C power adapters work okay for a Pi 5 without any accessories, but once you add things like a PCIe hat and NVMe SSD card, or external USB devices, it's easy to run into troubles. I tried out the SunFounder 27W adapter with some of the lab Raspberry PI 5's and had no issues powering the Pi and all of its accessories. The adapter stayed fairly cool to the touch and supplied enough current to keep everything running even with multiple hat cards and an external USB SSD plugged in. Very impressive. It's smaller than the stock adapter too. If you're having power issues with your loaded Pi 5, this is the answer.
