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

Converted a beat and busted Pac-Man Arcade1up into a RetroPie1up cab. Was getting undervolting errors time to time so I upped the amps with one of these and it worked perfect. No more undervolt!

Had a problem with some power supplies just not quite giving enough juice. This one works every time, and makes insufficient power a non-issue.

Tried countless usb cables and charger blocks. Running octoprint with a webcam and no problems the second i plugged it in. instant relief

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 I did not use to get this until I loaded a newer version of the PI OS.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.

Good power source, overcomes low voltage alarms The Pi3B+ operates faster, inasmuch the pi only has a Zener and 47uF capacitor at the power input, it would be better off if a regulator were on the input and require a 9V supply that would be reduced by the regulator and able to provide ample current, it needs a pass transistor, not a Zener

This power supply has plenty of power and runs very cool. Recommend to any one having a problem with low voltage..

Use for my pi 3b+ and works great. No more low voltage indicator.

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

Stable power for my raspberry pi plus ssd. I had some issues in the past with an old phone power supply and this one resolved all these issues.

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