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

My Pi3B would ALWAYS give undervoltage warnings when plugging an xbox one controller in, (due to the sudden rumble, I assume). It would also give the warning during other activities sometimes. I didnt even overclock anything. Now I can fully overclock the machine and never see the undervoltage occur.

The power supply arrived on time, in good shape, and is working as expected. My Raspberry Pi 3b is several years old and the power supply that came with the kit was starting to show low power on the Pi. It is obvious that the original one was not designed for years of constant use. I use my Pi as a small web and database server for my home network so it is up 24/7. From what I can see the Argon ONE is a perfect replacement. I have high hopes that this power supply will last for years.

doa. doesnt work.

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 product is just as described. Works well with my retro Pi setup. I bought it to give my retro Pi a little more power.

I purchased an Argon ONE case and with my generic 3A adapter, I got constant under voltage errors, even just sitting at the splash screen. This solved all of that and will be my go-to PSU for any further RPi builds.

This is a great power supply with a nice cord length. It provides good power to my raspberry pi 3 and the 7 touchscreen with no issues thus far. Highly recommend.

Bought this to resolve a constant under-voltage issue my other various micro usb power adapters were giving me with my RPi3B. I initially received a defective unit but the replacement unit was sent so fast i received it next day and it works flawlessly so I am not taking any stars off for that. I am extremely satisfied with this power adapter.

I have a Pi 3B+ and with the acrylic case, it was running sometimes up to 50C. Thats still tolerable for the pi but I wanted to keep it even cooler. This box does an outstanding job that it has yet to even kick the fan in! My Pi now runs around 36.5 idle and no more than 40C when under load. Its stylish and fits nicely on my desk since all the connections face the same direction now. Kudos to the Argon40 folks for coming up with this great design.

I was frustrated because I had a 2.5A 5V power adapter but my Raspberry Pi 3 started complaining that it had a low voltage after 2 years of continuous use. I tried other power supplies, other cables, all over 2.5A and still got the error. This power supply made all of that go away. Well worth the price.
