Argon Micro USB Cable Power Supply 5.25 Volts 3 Amps for Raspberry Pi 3 and Zero Boards | UL Listed | 3.3 Feet Long Cable with Micro USB Connector | Micro USB Cable and Wall Charger

I got this because I was seeing under voltage warnings from my Pi 3b+ with a 2.5A Rhino brand power supply. This fixed it so Im happy.

Works perfectly

The power supply arrived on time, in good shape, and is working as expected. My Raspberry Pi 3b is several years old and the power supply that came with the kit was starting to show low power on the Pi. It is obvious that the original one was not designed for years of constant use. I use my Pi as a small web and database server for my home network so it is up 24/7. From what I can see the Argon ONE is a perfect replacement. I have high hopes that this power supply will last for years.

I’m using this with a raspberry pi 3 B+. It is a quality power supply with good specs. It is also UL listed.

Powerful and reliable power source for my pi 3 b+. It can handle heavy use with several attachments and you will never see a lightning bolt.

Works as expected to power my NAS RPi.

This is a great power supply with a nice cord length. It provides good power to my raspberry pi 3 and the 7 touchscreen with no issues thus far. Highly recommend.

Changing to these after one of the stock units started making noise and was warm to the touch.

Bought it for a retropie setup so that I wouldnt see the dreaded lightning bolt anymore and it worked.

This power supply has a Micro USB plug, just like it states in the title. The Raspberry Pi 4 requires a USB C plug for power. As such, if youre looking for a power supply for the RPi 4, search for this *other* model on Amazon: Argon ONE Raspberry Pi 4 USB Type C Cable Power Supply
