A 36Wh POWER BANK JUST RAN A FULL MAC MINI M4 FOR 3 HOURS 40 MINUTES
Idle draw in the test: 1.5W.
Light work (web, files, agents): 3–5W.
That is not a laptop number.
That is desktop-class macOS running off something the size of a soap bar.
iPad becomes the touchscreen via Sidecar.
Apple Vision Pro becomes the big screen.
Foldable keyboard + trackpad and the whole kit fits in a small bag.
For people building local agents this changes the travel equation completely.
You no longer need reliable internet or a remote machine.
You can tune prompts, edit files, test agents, and keep the full environment offline on a plane, in a café, in a car.
Apple official idle is ~4W.
Independent wall measurements usually land between 2.6–4.1W.
This test shows what happens when the system is dialed in and conversion losses are low.
A tiny power bank is no longer a toy.
It is enough for real sessions of local AI work.
The limitation is still real: heat, memory, and peak loads.
But the baseline efficiency is now so good that portable full macOS stopped being a meme.
