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 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.

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

Was having issues with my other power supply on the raspberry Pi B+. No issues at all now with this one. Highly recommended.

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+...

Works well. Powers several rtlsdrs.

Ahh!! finally. I tried a bunch of chargers, plugs, wires, and finally decided to try this. I use 2 SDRs on my Pi and noticed even with 5v 2.5A usb chargers I would get lightning bolts on boot or when im doing heavy tasks. with this I finally noticed when I boot I dont have any issues.

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

Seems like a quality item, has worked well with my R-Pi 0W based Jumbo Spot digital HAM radio modem. The power supply is rated at a much higher current draw than the current application but I’d rather do that than get an under rated one. Would buy again if needed.

Works great.

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