I bought a portable AC battery for my Mac mini for $65. Hard agree though that it would be a lot cooler if the conversion was in the cable so I could just do dc in.
The thing is, M chips run so efficiently that even with the power loss from conversion, it’s still pulling less power than a lot of PCs.
But yeah it running on a sleek dc battery would be a lot cooler
That gives a lot more options IMHO on how to handle power for this machine, including portability, even if it's supposed to be a desktop machine.
I thought the same for the minisforum machines which would be competitive to this, they have a 19V input that really should be USB-C at this point.
