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

This thing is the best power supply for the Pi 4, hands down.

My RPI 3 runs great with this power supply. No more low voltage indicator coming on.

My OEM CanaKit power supply gave me undervolting warnings when using it with my Pi3 as an OctoPrint server for my 3D printer and while I had thought there was no way that an OEM power supply could be delivering inconsistent voltages; after I bought and installed this all the warnings disappeared. Would recommend this if you use your Pi in an important use case.

I purchased this power supply to power an OctoPi instance. My resend ratio shot through the roof on this supply. I was using a samsung usb charger (2.1amp) that I got with a phone to power the pi and my resend ratio was 0%. When I swapped it for this power supply my resend ratio shot up to 17% and the printer started pausing during the print resulting in stringing and poor quality prints. When I stopped using this power supply my resend ratio went back to 0%. I can not recommend this power supply.

I tried a few less expensive power supplies that claimed to be 3A but they were still producing undervolts on my Pi running Retropie. This one doesnt, so its highly recommended. Worth spending a few extra bucks for the quality.

My Pi3B would ALWAYS give undervoltage warnings when plugging an xbox one controller in, (due to the sudden rumble, I assume). It would also give the warning during other activities sometimes. I didnt even overclock anything. Now I can fully overclock the machine and never see the undervoltage occur.

Does what its supposed to do, and feels solid. Good power supply for nespi cases.

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

Very well made. Heavy cable made to last

Perfect for my needs. I have an overclocked raspberry pi 3 B+. This has retropie installed with a fan and custom power button installed. When running four controllers for mutiplayer games my old power adapter would have voltage problems which would cause problems with the pi, controllers, and games. This solved all issues I had. I will be using this power adapter in for all other projects in the future. Thank you!
