    Easy to read display, intense brightness, faster load than the familiar ones, low consumption when on standby, led that helps a lot like flashlight, I made my DIY with 4, 8 and another with 12 18650 batteries and works very well. It does not heat when in charge or when in discharge, the exit of 2.1A is perfect and solves all the problems. I tested it with a soldering iron bought here at BangGood and it made me happy and happy. I highly recommend it

    I ordered 5 sets of them and all working. The percentage meter is not so accurate. When I connect to fully charged 4.2V lithium ion battery, some show 94%-96%. The output voltage is about 5.2-5.3V. Good for DIY powerbank or boost up lithium ion battery to 5V application up to 2A, Value for money.
