I was initially sceptical of USB-C, but was looking forward to having less things to plug in. Then I learnt that USB-C only supports up to 100W of power, and even worse the MBP included charger is only 87W. All high performance laptops draw more power than that at high load (think gaming, rendering, etc.). I just don't see USB-C ever replacing a proper charging cable if it can't even supply enough power to run the computer! The computer you leave to render overnight will drain the battery to flat and subsequently shut down/throttle. How is that in any way acceptable?

What was the wattage on the older models?

  The most powerful MagSafe adapter is 85W. GP must be talking about some PC gaming laptop

  I'd classify any laptop with 6 or more intel cores and a dedicated gpu >= rx560/gtx1050(ti). Not so sure about mobile, but a desktop RX560 on its own uses 80-100W[0] which doesn't really leave any headroom for a 6 (yet alone an 8 core) cpu.

    Recent MBP15s have 6 or 8 cores, and at least Radeon pro555, 560 or some variety of Vega. They run on an 87W charger fine.

Two USB-C ports in parallel would get you to 200W.

  According to this[0], Macbooks will only charge off one cable. Not sure if anything has changed in that regard since 2016, but I'd wager it hasn't.

    The comment was about USB-C generally, not limited to the MacBook implementation. There isn’t an inherent reason why two cables couldn’t carry twice the power of one.

MagSafe 1 and 2 topped out at 85W. There are gaming laptops that require more than one brick-sized charger. There are legitimate complaints in this thread, but this isn’t one of them.
