    Received in good condition, item is as good as it is prescribed, tested for charging my lithium battery pack and it worked. Adjusting knob and values are accurate. I recommend to everyone. 👏

    Very well made tool, I personally put it in a 3D printed box with special slots for airflow and current output input. I also added an extra fan to cool the whole thing down better. Very versatile and accurate tool, there are well made videos that illustrate the calibration, operation, and quality.

    Received WZ10020L much earlier than expected. Thanks for that, Banggood! Module works fine and it meets the description. I draw 19A for more than 2 hours and the reported (by the device itself) temperature has reached 51-52 Celsius degrees. Not bad at all given the high, close to the 20A limit amperage. Fan works silently but effectively and it starts spinning only when amp draw is over 5A or temperature.exceeds 45C All in all, this seems to be a decent DC/DC buck converter. Hope it will last for a long time as well. So far, definitely recommended.
