I won't be trying the fastest PD charging modes with non-original cable and charger anyway — it's simply not safe. And they do have a chip, but e.g. a 2024 iPad can get charged just fine with a USB-C charger that came with my Lumia 950 from 2015 — it takes like an hour, not half a day, even though iPad has a high-capacity battery and that charger's "fast charge" mode not being that exactly fast by today's standards — it's not even remotely that bad.
