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

The package says Raspberry Pi 4 but it is MicroUSB and not USB-C. You should stop selling this or change the packaging and description. Returned.

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 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.

I was recommended this power supply for my Raspberry Pi3A build as a cellphone adapters 1A is said to not be powerful enough and may cause problems with the optical drive I have in the unit. Nice build quality and no cheap male USB to break off, but a nice power brick.

Works great.

It works well, gets rid of the low voltage icon on my pi.

Converted a beat and busted Pac-Man Arcade1up into a RetroPie1up cab. Was getting undervolting errors time to time so I upped the amps with one of these and it worked perfect. No more undervolt!

bought this for my Pi3B. works great. it is a bit large of an adapter, but thats ok i guess. oh and the wires go vertical and not horizontal like some other adapters, just be mindful of that if youre planning on putting it a surge protector or power strip so you have space. other than that, it works great. i bought a case that has an On/Off switch, so i didnt need an adapter that has that feature. in the future though, i will consider a power adapter w/ an on/off switch

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

super cheap and was able to get rid of my non-sufficient power problems.
