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.

So far I have used this for SD and Micro SD cards. I am assuming that it will work for other memory devices

Works perfectly

Couldnt be happier! This is the fourth power supply Ive tried on my Pi 3 B+, and the first that allowed me to use it without the dreaded lightning bolt appearing on screen. Everything from booting up, light web browsing, watching some videos, and streaming games with Steam Link worked flawlessly with no power issues. Thanks Argon Forty for making an amazing product!

This power brick for the pi 3 eliminated the lighting bolt on screen with the snes case. Gave it a go since I had the Argon One M.2 case and power brick for the pi4. I loved it so much and got this one. Solid device. 3.5A is a must.

No more lightning bolt in RPi3b+!

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

Works great, buy this one if there is not a microcenter near you that sells the OEM one cheaper than Amazon does.

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.

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