Argon 5.25V 3A Power Supply for Raspberry Pi 3 & Zero | UL Listed Micro USB Charger | Stable 5.25V Output Prevents Undervoltage | 3.3ft Built-in Cable | 100-240V AC Adapter

After several attempts to find the right power supply for my Raspberry Pi, the Argon USB PS fit the bill. I now do not receive a low power warning on the Octopi for my 3D printing. Excellent choice with excellent results.

Small enough to use the other plugs. Gives enough power to get rid of the lightning bolt. Does it's job may need to buy another for my second pi.

I tried several power adapters and got a lot of low voltage warnings. Granted, they were chargers and not proper power supplies. No low voltage warnings since using this. Seems to be well made and the price is good. This provides plenty of power to my Pi and fixed my problems!

So many electronic devices sold by Amazon have certification logos printed on them but they aren't actually certified. These guys ARE actually in the UL Solutions (formerly Underwriters Laboratories) (UL) database. The listing number on the box is "E480515". If you search for that on the UL site, part number "XSD-aaabbbbxyyz" is listed. The part number on the box is "XSD-0503000SUSD". The company listed is Shenzhen Sunshine Technological Co Ltd. Argon Forty Technologies, Inc is a reseller of these devices. UL listing means the device has been evaluated by a third party testing facility (UL) to be safe from shock or fire in reasonable use in a consumer environment. It's similar to CE in Europe, but in Europe CE is legally required whereas UL is optional. I trust this power supply I plan to replace my other Pi power supplies with these ones going forward.

It solved the low voltage warning problem I was having with my Pi 3, but I use it for Octoprint which is a relatively low power use case. Depending on your use case mileage may vary. I tested it with my USB voltage tester and it doesn't quite hit 5.25 volts even when current is under an amp. At 3 amps it drops just under 5V. This isn't ideal, but it still is much better than other power supplies I've tested. I believe the limiting factor with these power supplies is the cable and micro USB connector. Just a design flaw with the model 3 having a micro USB power port.

Perfect for raspberry pi 2 with Smartipi pro case and original touch screen.📺 . Works with pi 4 and maybe 5 with usb c adapter

This thing is awesome. At first I measured 5.16v (with no load) so I was disappointed, then I realized that the more current you take and the more it boosts the voltage. In other words it's a SMART PSU. Under some good load it goes up to 5.27v, therefore compensating for any loss in the cable. Brilliant!

Great ac adapter for Rpi3. No under current warnings, and the straight through plug allows you to not block the second or adjacent outlet when it is plugged in. The picture makes it seem like the prongs fold, but they do not. it's straight out.

The original power supply for my Raspberry Pi 3b started acting weird less than a year after I bought it. This one seems more sturdy than the original and after a month I don't have any issue. I might buy a new one for my second Raspberry Pi which shows CPU voltage issue once in while.

Muy buen producto, la fabricación es muy buena y robust, a demás de su funcionamiento que es excelente

only issue ... no switch .

No more low power warning. Worked for Raspberry Pi 3.

Excellent for my raspberrypi running nodes tryed one first then purchased two more
