> The power brick had a 2m detachable line-voltage cable, and fixed 2m low voltage cable. 2 + 2 = 4. I can sit 4m from the wall and charge using only the power adapter that came with the computer.
There's also the usual Apple Upgrade tax, the old charger was 85-90 euros and came with 4m of cable. The new one comes without a cable, is 99 euros and needs a 30 euro USB-C PD cable.
The new one is also much more useful, because it charges any arbitrary USB device: smartphones, tablets, visitors’ PC laptops, miscellaneous small gadgets, ...
Also, if the USB-C cord frays or breaks, it is replaceable.
I’m a bit sad about the loss of the magnetic connector, but overall I much prefer the new chargers.
I still wish someone would get around to putting 2–3 USB-C ports in a power strip which were capable of charging laptops though.
The old MagSafe stuff you could only (legitimately) buy from Apple. The USB-C stuff you can buy from anyone, and there are some decent quality cables and power supplies available that don't require you to pay the Apple tax.
Still the same with the USB-C power adapters, except that the detachable extension cord isn't included with new devices anymore. You can either use one from an old Mac, buy one from Apple (with the usual Apple-tax (https://www.apple.com/shop/product/MK122LL/A/power-adapter-e...), or get a cheap third-party one (https://www.amazon.com/s?k=apple+power+adapter+extension+cab...).
