Review on ⚡️ MYSWEETY Adjustable DC Power Voltage Converter - AC 110V-220V to DC 0-48V Module Switching Power Supply with Digital Display, 480W Voltage Regulator Transformer and Built-in Cooling Fan by Kyle Rock

It works as expected. A few things they could improve. It would be nice if the potentiometer knob was bigger to make the voltage setting easier to set for fractional values (especially at lower voltages); A small number of knob turns will result in relatively large voltage changes. In addition, the accuracy of the voltage display is reduced by 300-500 mV. (Regardless of whether you have a multimeter or don't need to set the setpoint precisely. And it would be nice to be able to limit the current like the voltage with a rotary control. It doesn't always have to be 10A available! ( And together with current display.) Overall is this a very good variable power supply for the price Update: I have two of these and sometime in the last year both stopped delivering over 50w at 36v but they are fine as long as they are work.
