Today I looked upon my desk: as you can see in the screenshot below, there are three plastic boxes containing A/C adapters for (I think all in the 12-20V and 1-2A range):
- screen device
- notebook docking station
Altogether they are worse almost 2 kilograms metal and plastic.
My question is: are these dimensions already optimal, or could be same functionality put in significantly smaller size (like more than a half, or even 1/10?)
Or is this is by physics already mature technology which is not expected to improve?
Note: with keyword "feasible" I mean the fact that I understand that miniaturization would cost more: "not feasible" means in this context like a 10-100x fold price increase.
