To correct myself, having read elsewhere: the M3 16” Macbook Pros (not earlier M-chip versions) can now do 140W charging on both the MagSafe 3 port (as with earlier M-chip versions), but also now on the USB-C ports.

Whereas before it didn’t make sense to use an EPR-capable USB-C cable for the MBP16 (as it only charged via EPR over MagSafe), new MBP16 owners may now want to consider it, instead of the MagSafe cable - 1 less cable in the bag.

So, it seems there are now 3 laptop lines which can do >100W charging via USB-C: the Framework 16, M3 16” MacBook Pros, and the MSI A13VX Prestige 16 Evo. Still, the Framework 16 is currently the only one which can do 180W charging - as well as 240W charging, once a necessary 240W/48V charger exists.
