I'll test it yet, but it seems all right

I bought it for $11.42 Delivery to Ukraine in 34 days (it was during the virus epidemic in China). Min output voltage 3.37V Maximum output voltage 24.7V In general, the device is quite good, but there are a couple of drawbacks: the cable is not heat resistant, does not withstand 200°C (not tried below). Short cable inlet - 50cm.

Good value for the money. The regulator is not linear, in lower range it jumps up & down, hard to set a value, in higher range it's ok.

Good power supply. Adjustable from 3.5V to 24.5V. PCB looks good, but be better soldered. HOT side PWM controller CR6850 (smd sot-23-6), power mosfet CDT6N60. Capacitors 47uF400V+10uF400V. Cold side diode STPR1020, 680uF35V *2. and AZ431AN shunt regulators.

I have determined the following parameters for the supplied power supply, bottom stop: measured 3.37V, display 3.39V, no-load losses 0.14W top stop: measured 24,21V, display 24,9V, no-load losses 0,84W The ripple is considerable with about 420mV, especially in the lower voltage range. There are also much stronger needle pulses. The output circuit is therefore insufficiently filtered. I found an efficiency of just over 86%, at 24V and 40W. My measuring equipment for this are not so accurate. I would not use the power supply for computer technology. It can be used for electronics experiments above 5V and for the supply of smaller AF power amplifiers. But you should provide an additional support capacitor. Bei der gelieferten Stromversorgung habe ich folgende Parameter ermittelt, unterer Anschlag: gemessen 3,37V, Anzeige 3,39V, Leerlaufverluste 0,14W oberer Anschlag: gemessen 24,21V, Anzeige 24,9V, Leerlaufverluste 0,84W Die Welligkeit ist mit etwa 420mV erheblich, insbesondere im unteren Spannungsbereich. Es treten auch noch wesentlich stärkere Nadelimpulse auf. Der Ausgangskreis ist demnach unzureichend gefiltert. Ich habe einen Wirkungsgrad von etwas über 86% ermittelt, bei 24V und 40W. Meine Messmittel hierfür sind aber nicht so genau. Die Stromversorgung würde ich nicht für Computertechnik einsetzen. Sie ist einsetzbar für Elektronik-Experimente oberhalb 5V und zur Versorgung von kleineren NF-Endverstärkern. Einen zusätzlichen Stütz-Kondensator sollte man aber vorsehen.

and my quick test with 24.5 V on a 11.2 Ohm resistor results in 2.22 Amp. (24.5/11.2 = 2.12 Amp). The power supply unit is good.

Подключил к блоку питания монитор на 12В 2А, он заработал. Без нагрузки индикатор на БП отображает 3,33В (мин.) и 24,5В (мах). Длина шнура от вилки 220В до БП 114 см, от БП до цилиндрического разъема - 60 см. Оба провода мягкие. Есть четыре отверстия для крепления к плоской горизонтальной поверхности. Устройство оставило положительные впечатления.

محول من ٣.٣ فولت الى ٢٥ فولت تقريبا ممتاز جدا وانصح به
