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

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.

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.

I used to have low voltage warnings and usb devices attached to my Pi wont function properly. My devices are running smoothly after replacing the power supply.

So far this has been a great power supply for my Raspberry Pi 3 A+. It provides stable reliable power and Ive had no issues.

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

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

Awesome power supplies.

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

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.

Running Call Attendant on an Rpi3b with a US Robotics modem to screen telemarketers, robocalls, etc. on a landline. Works perfect. Hasnt crashed, or needed to be rebooted in months.
