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

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

Using the standard 2.5A power adapter with a wired mouse, a wired keyboard and portable HDD attached to the USB ports, my RPi 3B always had the low voltage warning on. A 3A power adapter like this one seems to solve my problem.

Had an old micro usb power supply from Canakit from old RPi2 however was constantly throwing low voltage errors in Octoprint when connected to the RPi3 b+...

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.

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

The 5.25V output voltage fixed the low voltage warning for my Raspberry Pi 3B+ when also running a camera. The 5.0 V power supply that I had would drop slightly below the minimum 4.90V requirement for the 3B+ due to resistive losses in the cable. With the Argon One supply, my Pi 3B+ runs safely above the low voltage limit.

HAVE NOT USED YET BUT IT TESTING GOOD AND WITH PIS CHEAP IS NOT A WAY TO GO

Cable and power supply feel substantial. Seems to work as expected.

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

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.
