    Got myself into a bit of face-meet-palm situation while wiring a +5v power cable for my SJ4000 camera. Reverse polarity did its thing.
    There is no obvious damage, blown/black bits but i suspect i have blown UN8HX charging IC.
    I cant find a replacement for it in UK and trying to get it somewhere that doesnt involve slow boat from china or 30gbp delivery charge for a grain of sand.
    The camera works just fine when hooked up to usb cable, which is also charging port, but charging capability is gone.

    Alternately i might replace it with analogous replacement if i knew what they were.

    Maybe someone here (uk based) might spare one IC, i'll pay the part and shipping of course.

    I googled the part number to find out what it was. Several other part numbers were listed as equivalents if that helps:

    Slow boat from china it is. Shopping for discreete components is apparently a nightmare...

    And what a hell is with delivery charges in uk ? 12 pounds to deliver a single smd component ?

    Have you tried digikey or mouser and selecting the USPS shipping option? The USPS priority mail rates for international are excellent.

    Royal mail impose a racketeering 'handling charge' to collect import duty.

    For small value orders, some Chinese suppliers put "gift" on the declaration - no duty/no handling charge.

    There is probably a value threshold for duty to be applicable.
