i have apple watch 5 old charger and i got ultra 1 now.

I was thinking not even using new charger, i dont sleep with watches so i always charge overnight.

charging my ultra with old charger will always charge it in 7 hours no?

And maybe its even better for keeping battery healthy?

Is my thinking correct?

I upgraded from a S6 to a S9 and I intended to do the same but the battery charges so slow with the USB-A cable that I ended up using the USB-C, probably because of the bigger battery. I would assume that it would be even worse with the AWU and it's huge battery.

Being completely honest: just buy another power brick. Fast charging is something you think don't need until you do.
