    Nice step up converter. Very tiny, so it can fit in tictac box. Do not charge phone as shown on picture!! Intended for another interface.. No phones were harmed in process ;)

    Cztery gwiazdki za to że utrzymuje Uout dopuki Uin≤Uout. Dla moich potrzeb wystarczy (Lampa 24VDC zasilana z akumulatora 12V).

    Within a 4-35V input range, this device works very nice. Unloaded, the output can reach over 40V output from 5V in. The real danger is when the input drops below 3,5V. If this happens, the output becomes unstable and very high (60V or higher) which can damage circuits attached to it, be carefull! Also, because of the large caps, the voltage on the output takes almost 5 seconds to completely return to 0 after disconnecting the input voltage.
