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

Fixed my Octoprint server that started hating all power supplies and all power cables after a couple of years.

Charges, FAST. Works on Rpi4 and Asus Tinkerboard, havent had a shutdown yet in some high power applications.

The Argin cases and power supplies are first rate. I use them for all of my Raspberry PI needs.

The other power supply i tried gave low voltage problems but this one works perfectly

No more lightning bolt in RPi3b+!

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.

Very well made. Heavy cable made to last

I guess the 5.25v and 3 amps does the trick on the Raspberry Pi 3 with a PI touchscreen. The low voltage warning lightning bolt is gone. I did not use to get this until I loaded a newer version of the PI OS. Oh well, the power supply seems well put together and has a sufficiently long cord.

I purchased an Argon ONE case and with my generic 3A adapter, I got constant under voltage errors, even just sitting at the splash screen. This solved all of that and will be my go-to PSU for any further RPi builds.

Im using this to power a RPI3 that is participating in the SETI@Home project. With the original power supply I was getting intermittent low voltage alarms, with this supply Im not seeing any errors. This RPi3 runs 24 hours a day at about 75% CPU utilization without problems. There is a fan and heatsink on the processor. It has been running for a couple of months now. Trouble free!
