HiLetgo Adjustable Step Up Constant Converter Review

Does exactly what it's supposed to do. The only problem is that the potentiometers are a bit fragile and could be more reliable.

Runs at 60 watts with ease. The core is glued to the metal plate but not the covers. When orienting the board so that the silkscreen legend is visible, decrease the voltage and current clockwise.

Good quality small power supply. The output filter caps are a bit underrated for true full output voltage (no load), but that's exactly what I need for my application. For full current, it is necessary to lay the bottom (aluminum) on the heatsink over a large area in order for the cooler to work. Will definitely buy again if needed.

After adjusting the voltage with the CV knob, adjust the CC knob by turning it clockwise with no load until the voltage drops. This means it is below the lowest possible power setting. Now you can connect the load and slowly increase the CC by turning it counterclockwise. If you connect a load without following the steps above, the module will most likely be damaged (in my case the module was able to run 15 amps at 24 volts for about a minute and burned out while I was turning the…

After watching some videos on Youtube I got this to try to revive a Ryobi 40v battery pack that was no longer charging. There are no instructions, so you have to figure everything out yourself. There are also no meters for the output, so you'll need a multimeter so you can see the actual output while you make adjustments. I had to connect to an old laptop power supply (19V, 4.5A), had to try several times until the output was actually set to 40V. There is a faint click when charging, which is…
