While charging my Apple Watch on a Geekera charging station it will repeatedly ding.

The Apple watch does not use Qi charging. If you device is not MFi certified it may have been using stolen codes to make the Watch charger function. When Apple made changes that affected the chipsets in the Watch cable they no longer worked properly. Contact the manufacturer.

With three replies having the same issue with different chargers, it's clearly not the charger. There's a problem with the update.

There is only 2 brands mentioned here although there are 3 chargers. Is the one you are using Made for iDevice certified?

You would have a better chance at an answer if Geekera has a forum and asking your question there.

I bought mine on Amazon, and the description says it's compatible with Qi charging for Apple products. Interesting that it worked fine for a full year until the recent watch update.

I'm having the same issue since the recent update. I have a Zubarr charger.

Even on Apple charger for watch the one that came with it keeps doing that

Having the same problem with AW 7 since the 8.5 update.
