- Anker 65W: 1.65 x 1.42 x 1.74 (4 ounces)
- Apple 140W: 5.52 x 4.64 x 1.28 inches (12 ounces)
- Anker is 4.07 cubic inches
- Apple's is 32.7 cubic inches
- Apple's weighs 3 times as much.
- Apple's charger has about 60% more wattage but is 3x heavier.
- apple's charger is 8 times larger than Anker's by cubic inches
electronics aren't always a matter of multiplication as a linear curve but apple's is a GAN I charger and Anker's is GAN II that's why it's smaller. I'm challenging Apple who is selling a charger that costs $99 instead of $39 to at least only be double the size of Anker's versus 3X the size and that comes through Apple adopting better design. I think Apple can make their charger smaller and chose not to for price reasons.
There are GAN II 100W adapters out there that are much smaller than Apple's and all I'd lose is, at peak performance, the apple laptop would discharge slightly. I think that's what I'll have to do as Apple's brick is just too large for travel.
