Aclorol 5V 5A 25W AC to DC Power Supply Converter 5.5X2.5mm Plug AC 100V~240V Input DC 5volts Power Adapter 5amp Switching Transformer for WS2811 WS2812 LED Strip Light Security System

I bought this 5v 8a power supply to power my Atomic Pi (API). Before plugging it into my API, I used my Fluke multimeter to test the voltage. I got a reading of 5.39v. The API documentation says not to exceed 5.2v. Despite the fact that it exceeded the recommended voltage, I decided to try it anyway. I connected it to my API and it booted it up without any issues. While powering the API, the voltage reading is 5.15v. This ends up being perfect since slightly higher than 5v is desirable but exceeding the maximum safe voltage is not. My API has been running 24/7 for a week now without any issues. I will update my review if anything changes, but so far I recommend this power supply. Make sure you use a multimeter to measure the voltage before using it for your project since there could be deviation from one unit to the other.

The power supply is used to power a WS8212B LED strip and an ESP8266. At full brightness white color the strip consumes close to 5A with the voltage sustaining a little above 5V, Under these conditions the power supply brick becomes warm to touch. However, when we initially used the provided female socket adapter the adapter became hot and the voltage drop on the adapter connection was about 2.5V. That connector was radiating power like a small 12.5W soldering iron. In the end we cut the plug and connected the power supply permanently to the prototype board.

Used to power LED's for a 3d printer. Worked great and still plenty of power to spare for more Mods.

Edit - After placing this review, Aclorol messaged PM'd me and after some basic troubleshooting, sent a new power supply. I appreciate the customer service This stopped working after 5 weeks of sporadic use. It conveniently stopped working shortly after Amazon's (very short) return period ended.

This is a solid & substantial power supply. It is high quality & can handle everything 5V that you could need it for. To be honest, it almost feels like overkill for what I am using it for, which is just to power a strip of addressable LED lights that I installed around my daughter's bed. It far exceeds my intended use for it & I'm sure it would yours too!

Sold as a 5v 6a 30w power brick. A 20w load draws voltage down to 4.7 and falls even further. It’s junk.

So I needed 5v and 10 amps x2 and 5v 6amps for 3 projects, actually one, but couldn't find 1 power supply that's large enough and fairly inexpensive, but these were pretty cheap and had little plugs that implied they'd be good for DIY projects. So put first line together, 10 modules, each draw 1 amp when working and next to nothing when idle (measured). I plugged in the first module, couple flickers, then nothing, checked all wiring, attached an existing 5v supply from something else, everything lit up. Problem traced to the little dongle that split the power connection into 2 screw taps. Repaired it myself. -1 star. OK, everything is showing idle now, 10 lights. Tested each module 1 by 1. Everything works, so no problems with my wiring or any of the modules. Activated 4 of them, no problems. I did not check voltages at this point as I assume foolishly that 5 volts out of the supply with no load (tested while checking the first issue that I already repaired) would maintain level at 4/15ths of rated capacity. Activated 2 more modules, now showing 6 amp draw, but there are some odd flickers on the idle modules. Grab the multimeter again. 4.26-4.39 volts. Well I have 3, probably got a bad one. That happens. So I switch. No lights at all. 4.11 volts. Since the modules step down 5v to 4.2 anything lower than that makes them not work. So one supply will operate 6 amps, one won't handle 5. I haven't opened the third, I may return that one. 2 that won't hold just a bit over 1/3 their rated current, not good, at least for my application. May work well for something else. They seem stable at lower draw so I gave them 2 stars for that. Later Edit: I did return the other 2, but because I modified the end on the other 1 I kept it. Well I needed another smaller 5v power supply with lower amperage. This works well in an application drawing less amperage and an uneven load, so it's not complete junk. They get moved up to 3 stars. The little connector was perfect for the subsequent application.

I power a 5amp string of led lights. Works like a charm
