S21 Ultra - 25W or 40W supported?

[fbs4800]

Hi all, I keep finding conflicting information online... Some reports say the phone will take the highest rated chargers on the market, and others say it only supports 25W. I can't find a definite answer.

Also, are there higher rated cables? My Huawei P30 Pro had purple lined cables to get the absolute highest charge. What about this?

Can anyone help? Thanks in advance!

Unfortunately none of the S21's support 45W charging, only 25W

As mentioned, it's max charge is 25 Watts.
I just use my old 18 Watts charger as I charge at night and the S21 Ultra is an all day phone, so I doubt you could kill the battery unless you are at home whole day on it.

It's just 25W , I was using a spigen charger that was supposed to be 27w but only triggered fast charging, but when I swapped over to a proper 25W samsung one , it showed up as Super fast charging which I think is the proper 25W and reduced my charge time by quite a lot

I might be wrong but from what I understood is that you can use a 45W charger n it will work but the phone can only charge at a maximum of 25W. I might be wrong. either way phone only supports 25W

Yes you can and it charges the same as the 25W charger.
