Re: New chargers required
Sorry to explain here, I went looking for QC3.0 compliance, as I thought the S10 (Current device) was QC3.0 compliant (Turns out, it's not) so, not seeing QC3.0 compliance for the S21, I assumed that Samsung had walked away from QC and joined everyone else with USB-PD due to QC being a Qualcomm proprietary product, and Samsung probably not wanting to pay Qualcomm if they don't have to (Move to PD).
Turns out they do USB PD 2.0 as well as QC 2.0, and not QC 3.0:

USB-PD, will do 25W and QC2.0 / 3.0 will do 18W, but you don't have to swap everything immediately as you can still use QC 2.0.
