    This is a practical Power Bank enclosure, we can put a rechargeable 18650 battery into it, and we can easily remove and replace it, if it stopped working.

    The most important feature of these powerbanks is, in my view, the short circuit protection, as many of us have faulty wires, and as li-ion cells can easily provide currents in excess on 10A. This one does have short circuit protection, which actively resets once the short is resolved. As li-ion cells get damaged if discharged below ~3v, it's also important that these cases disconnect the power completely, so that no further discharging may occur (poor quality ones stop boosting the voltage up to 5v, and just leave a direct connection between the battery and USB port - which, if used to power passive consumers, such as LED lights, will result in over-discharging of the cell). This power-bank completely disconnects power once a threshold voltage is reached (~3.1v). Other facts: - output constantly kept at 5V, no matter how small the load. - 0.1 mA draw @ idle

    good deal for those who are interested in discovering how those USB power banks are made. For people interested in technical details, this case is based on a HT4928S chip made by HOTCHIP, which works as charger and DC-DC converter. Datasheet available only in chinese, but schematic easy to understand.

    All right, after a call from the Italian post office that said that the package was destroyed and was not delivered at the end it arrived perfectly but was put back in another envelope and then inside its original that was heat sealed again. Banggood's assistance was perfect in following what was happening. The product is great already in the past I had bought it and it worked well. Thanks Banggood.

    I ordered some of these powerbanks that I need for some experimental applications with burglar alarms. It was just what I needed, they are good and practical to use. Thanks as always Banggood.

    Produkt dobrze wykonany, ze sztywnego plastiku. Klapka zawsze jest biała, niezależnie od koloru obudowy. Powerbank jest zaprojektowany do jednorazowego włożenia ogniwa 18650 bez opcji późniejszego wyjmowania.
