volts x amps = watts
That totally makes sense. In other words my Note 10 brick is capable of 24.75w (11v x 2.25A) and the new brick is capable of 35w (20v x 1.75A). Yet, the difference in how fast either of them actually charge my phone is negligible. It almost feels like a waste of my Samsung credit.

Help me out, here. I ordered the dual 35w/15w brick from Samsung.

Super Fast Charging is triggered at anything over 24W iirc.. but also won't allow more than ~25W in "Super Fast Charging" so yes your 25W charger and your 35W charger will perform exactly the same.

The steps are:
15W = Fast Charging
25W = Super Fast Charging (requires 3A cord)
45W = Super Fast Charging 2.0 (requires 5A cord)

Each step only goes up to that limit but not over.

Any charger between 30-40W is a waste of money over a 25W charger.

Interesting. Why bother with 35w charging?

Question we have like 4 25W Samsung bricks we got with our 21 Ultra's for free with accessory credit. We bought these braided cables off Amazon due to our cats chewing on the regular ones for some reason the white ones more than the black LOL! My husband ordered 1 x 45W and uses it with his chromebook instead of the big charger that came with it. Anyway we just ordered 22 Ultra's and with our accessory credit even though we don't really need it got 2 x 45 watt bricks and couple more 25 watt external battery packs don't think they make 45 watt ones but anyway the cables we got off Amazon and that we use now with our 21 Ultra say Super Fast Charging but I don't know if they are 3A or 5A so are you saying with ourn ew 22 Ultras to get super fast charging we will also need different cables with our 45 watt brick? I guess I can go to my order history and try to find out. Thanks!

Did you not order the chargers that came with the 5A cables?

We ordered just 2 x 45 watt bricks from Samsung with our accessory credit we don't like the cables that come with the chargers our cats chew on them and we like these braided thicker ones off Amazon and prefer longer. I just wondered if now with our 25 watt and cable our S21 says Super Fast Charging over fast charging old style from my S10 plus. So does the 22 Ultra with a 45 watt say Super Fast also and if it does maybe our cables are good? I guess we'll find out phone coming today we weren't home yesterday.

If you don't use the Samsung cords you will only get Super Fast Charging (25W) not Super Fast 2.0(45W) that you get with the Samsung cords

Edit: I'm sorry but I'm just really confused cuz I found 5A cables that said 100 watt on Amazon the ones we have now may be 3A l have to check. I just know when I looked up I previous order of cables on Amazon I saw 60 watt. And someone said if we have a 45 watt brick 60 w will be fine we only need 100 watt if we had a 100 watt brick I don't know. And then Samsung said our cables are fine but I want to get the most out of the 45 watt brick. And somebody else on YouTube commented to me and said that it says super fast charging 2.0 with the right cable and Samsung told me no it just will say super fast charging. I have no idea but if it will be faster with the 5A cables then I would like to get some. I have Anker ones now from Amazon I like the 10 ft they're kind of braided cuz my cat's chew on the thin Samsung ones. But we're getting to 45 watt charging bricks for free so I want to get the most out of them and we can still use our 25 watt ones too that we have I have chargers all around the house.

I read through this thread, but I still want to make sure I'm not mistakenly buying a non-45WSF2.0 charger. Some, but not all, Anker model 7xx chargers have the following disclaimer:
"Supports Super Fast Charging for S22 Ultra but does not support 45W Super Fast Charging 2.0"
I've read rumors elsewhere that the 2.0 spec calls for ~4.5A at 10V=45W. The 726 just doesn't have the Amps' oomph bc it only goes up to 3.0A. The 735 doesn't list any of its Amperage and still has the same disclaimer. The 715 only gets to 3.25A. The 713 only gets 3.0A. Here's where things get fuzzy and frustrating: the 736--the one that is a 100W charger--doesn't list its Amperage, but it does not have the disclaimer. There's no manual listed for it or customer comments on it either. If someone had like a multimeter or something to check it, that'd be helpful, but I don't feel like spending $80USD on a gamble.
Well fine then, who can I rely on for a 45WSF2.0 charger then? Any third-parties, or does Samsung have a corner on this market?

I've actually been looking at purchasing one of these myself (the65, because the 100 doesn't seem to be on sale here). From my research, they don't support super fast charging 2, which doesnt bother me that much as I'm wanting it as a multiport charger (it is admittedly a little annoying lol).

I do have a Tab S8 though, which supports 45w, so if you can wait a week or so (I'm waiting for prime day so I can be dissapointed that nothing worth buying is on sale lol) then I can test it and tell you for sure.

Also, for what it's worth, the 3 digit ID appears to broken down as follows model, number of ports on included adapter (if any), wattage. so 735 would be 7 (nano2) 3 (3 port adapter), 5 (65w). I could be wrong but that seems to be the convention.

The 100w *should* work though... I can't find the spec either though, although I haven't looked that hard not being able to buy one.

This one from Spigen supports the PPS standard that you need for Samsung super fast charging. And it's GaN, so it is smaller than the OEM charger.

It has folding prongs and comes with a pretty good cable. It's also a lot less expensive than the OEM charger. I have several of them.
