It's confusing because it's a confusing sentence...
The 16-inch MBP comes with a 140W charger and USB-C to MagSafe cable. The 14-inch MBP comes with a 67W or 96W charger and USB-C to MagSafe cable. Maybe the dude you quoted was thinking about a purchase because the 140W adapter is
compatible with a lot of other devices?
[edit]: From the article above: "... Apple also confirmed that any of the new MacBooks’ Thunderbolt 4 ports can be used to charge the laptops. On the 14-inch MacBook Pro, these ports can be used for fast charging; but fast charging the 16-inch MacBook Pro requires using MagSafe 3 and the 140W adapter because the Thunderbolt 4 predates the USB-C PD 3.1 standard and tops out at 100W." I
think that's what your quoter was trying to say.
