5V 5A Power Supply,AC110/220V to DC5V 25W Universal Regulated Switching Power Converter Transformer for LED Strip Light,Probe Signal Lamp

I bought this 5V 5A power supply for my Arduino project and I'm happy with it. It works well and gives a stable 5V output. The only thing to watch out for is the heat. If you use more than 3A, it might need cooling because it starts to get warm at 2.5A. Other than that, it's a great product for the price.

A well made, stable power supply with the facility to adjust the output voltage using a small adjustment potentiometer on the circuit board.Needs mounting inside an insulated junction box, since the 240 volt supply wires are very exposed.

This powers the LED lights perfectly. The only down side is the high pitch noise when the lights are off, but it isn't loud enough to bother me unless it is really quiet. I will buy another one when I need it for another project.

Got this to power a strip of custom WS2812b LED's.Apart from the exposed terminals (Easily solved with an appropriate sized and ventilated project box (or just a tupperware and some tape!) i have 0 complaints!

power supply didn't even last 4 months of intermittent use

After hearing the squeal it was giving out when powered up, I decided to look up PSU whistling, and found that it was most likely mechanical in nature (coils vibrating). Whilst I fixed mine by opening it up and applying sealant blobs to the likely culprits, I would not condone this being done by anyone. Better to return the item and buy a better quality product like a Meanwell unit.

Output voltage unstable under load.Returned for refund.
