Got a gift from my friend. It was from an Indiegogo project. It worked fantastically until it has broken recently.
Although 1 year warranty was promised according to the site, the fact that it's from Indiegogo means that's non existence (I'd say if you actually receive the thing, you're very lucky). So I disassembled it and had a look.
Now I'm thinking maybe I just need to hack my way in to find out what that blown chip is and if I can replace it.
I am also disgusted by the Chinese printed on the IC...

    What was it before it was disassembled?

    @RiderExMachina it was a 4-in-1 car kit. I use the car wash water pump only. But since it's got a battery, it can jump start a car, be a power bank and the last feature is being a stupid hazard sign as it's big...

    @ctrl-alt-del Do keep us updated on this

    At least it's clear which component blew

    It looks like a diode. If it’s in series with a input, it may just be a polarity protection. If it is connected in parallel it may be a TVS diode to protect it from transient voltage.

    @lobelt I agree. Seems like a normal diode. IDK why it blew tho.

    @lobelt I'm looking for dudes like you to shed some light. The only thing I did potentially blew it was too charge it for longer than needed. Shouldn't have trusted it has protection for that... I was thinking it might be a capacitor.

    Ctrl-de@ctrl-alt-del I doubt it is a capacitor. Is the two connectors the battery terminal?

    Ctrl-de@ctrl-alt-del I doubt it is a capacitor. It is namned D3 (capacitor chould have been namned C3 insted) Is the two connectors below the battery terminal? It is most likely a zener acting as a crude charger by limiting the voltage in and out from the battery. Hard to say without some probing.

    Ps sorry for this late reply.

    looks like it might be a regulator with the placement? maybe?

    if so you could probably scoot by with just jumping it, at least for a while

    Haven't got time to come back to it yet. Will take it to the nearby electronic part shop and let the staff take a look too. This is something I'm okay to screw up. After "made in China" means "yep, it blows".
