can you charge an apple watch 9 with a usb A watch charger?

So far the exact same charging puck has worked for all Apple Watch models in the past. And looking at the Apple Watch accessaries, it looks like the same charging puck as before.

So if you have an existing Apple Watch charging puck, it should work.

The only limitation is if you have a very old charging puck, that model will not do "Fast Charging", but it will charge the Apple Watch.

My puck for my Apple Watch 6 would my charge v9. In fact as it was on the older puck the battery level DECREASED

My Apple Watch 9 is charging on my Apple Watch 1 USB charger right now. Not quickly mind you.

It would work just fine. It will not do "Fast" charging, but it will charge it just as fast as it charged your Series 6.

Fast Charging arrived with the Series 7, so the Series 7 and new charging pucks can charge faster when attached to a 20watt charging brick.

But the Series 7, 8, 9, Ultra I and Ultra II can still be charged with the Series 6 and older charging pucks.

The specs for the series 9 watch have not bent published yet. But I would expect that you can charge it with an older USB-A charger. You would just lose the fast charging feature. Just a guess.
