A part of the review has been auto-translated.
Yet to be tested, but looks good.
it is so small for the price, and i don't think it'll stay for long.
It works, but don't expect to get a lot of current from the output before it shuts down. I expected it to have a higher peak current even with the low typical current. It is also difficult to adjust as the no load voltage setting is not the same as the voltage you get with a load. I ended up putting an inline volage and current meter to setup the output and removing it once done.
prima product en levering.
