They are a good company, but not all their chargers are UL Listed apparently. I randomly picked one off Amazon and the box does not show UL Listed anywhere. I would expect to see the UL symbol if it was UL Listed.
Got a tip for us?

Apple's 140W Power Adapter is Company's First GaN Charger, Supports USB-C Power Delivery 3.1

Considering how Apple says it's so power-efficient, I have to agree. However, I also have an Alienware x17 laptop that needs something like a 240 watt power supply, but since it's a higher-end gaming laptop, I can understand.
I did not think that you can use multiple USB-C ports to do "additive power" to charge a laptop?
A real shame that there appears to be no LAN port on the power brick like with the iMac.
This was the only box not checked for me (on my wishlist) on these new MBPs. I too was really hoping that we'd see ethernet on the power brick.
MacBooks come with the cable when you buy them. Apple power adapters (even for their smaller devices don’t come with the power cables.
The USB C cable has to support the 140W PD 3.1, good luck finding one for cheaper, not all USB-C cables are created equal, some barely supporting 30W. Alas, show me a 140W charger that's cheaper / readily available...
No, you end up with an infinitely growing power brick because every time you say "hey! room for another USB-C in there" you add another 15W or more to the peak power consumption and have to make the power supply even bigger...
The primary purpose of these bricks is to charge the MacBook that they come with via the included MagSafe cable - connecting that via USB-C so you can use it to power other things is a nice bonus (plus it allows you to replace damaged cables) but you shouldn't become a victim of mission creep. If you really want a multi-port charger or docking station you can get one - and it looks like now you could still use the MagSafe cable with it.
...but it also connects via Magsafe which is designed to break away at the slightest tug rather than drag the Mac off the desk. Accidentally disconnecting the power on a laptop with its own battery is no big deal - whereas disconnecting Ethernet could cause apps to hang or crash, while pulling the USB plugs on external drives etc. could even cause data loss.
Contrast the magnetic connector on the iMac which has the opposite purpose to MagSafe - not to pull out easily and provide a secure connection without the grip provided by a much deeper connector.
Plus, the power brick is not the most convenient place to have ports if its going to be plugged into a socket near the floor. Even the iMac arrangement is pretty dumb, and was clearly spawned in an echo chamber where everybody lived in a building with hot & cold running ethernet sockets next to their power sockets (that's what those spiral cable tidies are for, folks!) and nobody had (e.g.) a router on their desk. Of course, the real reason for that is that some form-over-function nut desperately wanted to make the iMac so thin that it wasn't deep enough for standard sockets and an internal PSU, and everything else was after-the-fact rationalisation.
I’m assuming the maxed out 16” isn’t going to draw more than 96W considering that’s what is shipping with it. The 140W charger is most likely to utilize the quick charging feature.
It's not larger.
The screenshots in the store of the 140W and 96W charger must be to scale (since the "duckhead" plug is the same size on both).
The 96W charger is thicker and wider.
We know the 96W charger is about 7.8cm x 7.8cm x 2.8 cm = 170cm^3
Doing some screenshot math, the 140W charger looks to be around 9cm x 7.1cm x 2.4cm = 155cm^3
So the new one is about 10% smaller with 45% more power.

Yeah, that's a miss but my guess is with all the USB-C stuff, it wouldn't fit in there.
USB-C PD 3.1 supports up to 240 with a properly designed cable; so a USB-C port designed to the PD 3.1 spec should support more than 100W.
The new 4 port HyperJuice supports 245W but maxes out at 100W per port.
Yes, that's a good question. I have an LG USB-C monitor that keeps my 2018 15" charged but there is almost zero chance it will keep this beast charged. Also, I would assume that if Magsafe is plugged in as well as a USB-C power source, the MBP will detect that and default to Magsafe. But it's kind of scary to think about 😅
I guess not all GaN chargers need to flex about how small they can be lol
You can feel very confident in any of the Japanese standards (PSE). Japan doesn't fool around.
Same, I have a 95W USB-C GaN charger that is half the size of this one. Works like a charm, it charges my iPad Pro and other devices super fast at the same time.
And it came with a cable...
Yeah! I mean seriously, for something that large, wouldn't hurt to add an extra port so consumers can also charge their iPhone at the same time.
So much for environment, Apple wants you to buy one charger for every single devices you have...
Given this is GaN I'm surprised by how massive it is. Apple's chargers are usually really well made, but so are Anker chargers and they are a fraction of the size.
I'm waiting for Anker to release a 100W dual USB-C charger for my 14" MBP so when I travel I can charge my MacBook and MagSafe Duo Charger off of one brick.

Very well said. I‘m always amazed at the number of people who don’t think before posting the first reactive thought that pops into their head.
And for comparison: That 100W HyperJuice is 8.53cm x 6.08cm x 2.89cm = 149.88cm^3
That makes the 140W charger less than 5% bigger with 40% more power (but obviously only 1 port).
Overall, I'd conclude that the Apple charger is comparable to other GaN chargers in size.
