    I tested it. It works as expected. You might need to turn the potentiometer a few turns to see the effect on voltage. I think it's a nice power supply which is capable of adjusting not only voltage but also current. If you are looking for a better one with voltage display for a higher price, you might want to choose this one which is also very nice product but at higher price.

    As usual BangGood provides. Ordered Three of these converters. Working building E-Bike batteries I needed a way to charge 18650 batteries prior to testing. These will do the job. After using them for a while I realized I needed to charge More Batteries faster then I can using this Item. Now ordering two of the 600W Boost Converters to allow me to charge more then a few 18650's at one time. It would have been nice if BangGood would have provided a basic informational document with these

    I've ordered quite a few of these units. Keep finding more uses for them and ordering more. Suggesting them to friends for the same. This one was shipped to a friend to charge 38120 LIFEPO4 LITHIUM BATTERIES .
