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

Powerful and reliable power source for my pi 3 b+. It can handle heavy use with several attachments and you will never see a lightning bolt.

No more lightning bolt in RPi3b+!

Works well. Powers several rtlsdrs.

Powers a Raspberry Pi 3 with no problems. The box claims this power supply is suitable for Raspberry Pi 4 but its not. Raspberry Pi 4 uses a USB C power connector. This supply comes with a Micro USB connector thats permanently attached. Takes up some space on a power strip due to the design - if thats important to you.

No more under charging for better performance.

This power supply has plenty of power and runs very cool. Recommend to any one having a problem with low voltage..

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

Works as expected to power my NAS RPi.

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.

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.
