Good power supply. Switch could be better.
So far so good, but a few minor things (not enough to subtract a star). Using to power a 16x16 LED matrix with an ESP 32. I tested the power supply with a multimeter and there is a 50ohm resistance across 5v V-/V+ which seemed a little odd, but is most likely due to shunt or bleed resistance. Tested at load and it was fine, with a stable 5.1 volt. The power supply came set to 110 v. However, the voltage switch is inside the chassis, and would be difficult to change if set to 220. You may be able to get an allen key in there, but it's probably best to take the case off if you have to change it. Not a huge deal, but not ideal either. Other supplies provide easier access.

Perfect 5V supply to power a rack of Raspberry Pi5's
I put together a small four-node PI5 cluster and wanted a single supply to power all of them. With the assistance of some USB-C power cables, this supply easily handled the cluster's power needs. Perfect supply for the price.

potentially cheap and unsafe
received the product however one of the corners of the board was broken during shipping making the live connection contact the bottom and has me worried as to the safety of my unit.

Gutes günstiges Netzteil für meine LED Stripes
Günstiges, aber stabiles Netzteil. Man braucht aber noch ein Kaltgerätestecker mit Schutzleiter, sowas hat aber meiner Meinung jeder irgendwo Zuhause rumfliegen. Wird bei Dauerbetrieb etwas heiß (es ist kein Lüfter verbaut, kann aber Recht einfach eingebaut werden)

Funciona correctamente
El transformador funciona correctamente. La eficiencia que he encontrado en mi equipo es del 80% en algunos casos. La calidad del producto es muy buena. Recomiendo medir y ajustar el voltaje de salida ya que a mí me vino desajustado. Muy recomendable
