Internally this charger looks like a tiny implementation of a QI inductive phone charger, which makes sense. The main chip is triggering strong Deja Vu from a previous exploration of a standard QI charger.
The investigation was thwarted by the mystery chip, which may be a microcontroller or may be an ASIC (Application Specific Integrated Circuit.) My guess is a microcontroller with dedicated inductive charging functionality.
That said, the circuitry is interesting, and a useful reference for future designs.

    I have one of these chargers, but my Apple watch Series 7 doesn't like it. For some reason it constantly thinks it's disconnect and then connects again, causing charging to be really slow.

    Black background -> blackground. That's funny 😀

    Skineffect is what your looking for

  4. Avataaar/Circle Created with python_avatars matpsim says:

    They say a watched watch never charges

  5. Avataaar/Circle Created with python_avatars Azelus Nova says:

    Poundland is a very interesting store name 🤔

  6. Avataaar/Circle Created with python_avatars blackcorvo says:

    The ferrite material is somewhat similar to what is used in thin fridge magnets, as well as the magnets for fridge seals.

  7. Avataaar/Circle Created with python_avatars Derek Traywick says:

    So, how difficult would it be to take the chip apart and reverse engineer what's going on? Asking for a friend. 😉

  8. Avataaar/Circle Created with python_avatars Ilka M. says:

    I think, the capasitors, connected to the coil, are for doubling the voltage in the coil to increase the current. The higher the current, the higher the transferred energie.

    I wonder if it would charge a Seiko kinetic watch?

    Maybe litz wire? Braided wire where individual strands of wire take turns being on the outside to defeat the skin effect.

    I cannot hear the word “poundland” and not chuckle a little.

    if you had a big enough one of these in your driveway, and parked an ev on top of it, wouldit charge the car?
