Fast charging - brick or cable?

I'd like to charge my SE (2) with a 2m long cable (but Apple no longer sells a 2m charging cable). I have several bricks that are reasonable powerful and are USB A power supplies.

I understand that the new brick/cable charging combo charges the new SE2 faster than the old brick and old (USB A) cable did. Perhaps USB C handles power better than USB A did. Is that the case?

If I use a more powerful brick with the old cable, will it also charge rapidly? Or to simplify - is the new brick the more important part of the charging equation or is the new cable the more important part of the equation. Or are BOTH crucial to fast charging?

Sorry, missed the part where this was about an Apple Watch SE and not an iPhone SE.

Yes, the Lightning cable won't help you with an Apple Watch.

A 20w charger and a USB-A cable should allow it to fast charge yes.

Both are important to fast charging, but the brick is the more important part.

You need the extra power provided by a brick to fast charge. No cable alone will provide fast charging if the connected charger does not offer enough power for it.

To Fast charge, you need a 18watt or greater charger and a good quality cable. A good quality cable can be one that ends in traditional USB-A however.

And yes, Apple still sells 2m USB-A to Lightning cables to charge iPhones.
