Does the speed of charging the Watch 7 with its new charger vary with the wattage? For example, does a 96W power adapter charge faster than a 20W and does a 20W charge faster than a 5W?
Apple Watch Series 7
All Apple Watches will use ONLY what they need. The Series 7 will use no more than 20watts during fast charging (the up to 50% point), then it will use less, no matter how much potential the charging brick has to offer.
This applies to all Apple Watches. They will use ONLY what they want, and will not care if the source has more to give. The source cannot force more power into the Apple Watch. The Apple Watch regulates how much power it takes, and stops taking when it is fully charged.
So you can even use the 140watt M1 Max MacBook Pro charger, and it will not matter and it will not speed things up any more than a 20watt charger will.

Thanks Bob! The critical fact you provided was 20W is the max the watch will draw. Apple says you can use a 5W adaptor with it (which of course you can) but I didn't find anything that says "Use something with at least 20W to get the faster charging".
Does the speed of charging with this new charger vary with the wattage?
