You need to break down the issue into three seperate problem.
Problem 1: Target Voltage/Current
You need to know the Power requirement of your device.
Voltage is easy, because you only have 12V..
Current is a bit more tricky...
It depends HOW you use the hAP ac³
I think you should consider ~ 18 Watts (device + USB-Port, no PoE-Out)
This means 12V@1.5A
Problem 2: Transportation
a lot of Factors imfluence the delivery of electricity over a distance.
For exemple temperature, shape of conductors, interference to name only a few.
When powering a small Device indoors, you usually only have to take into account,
- Cable-Length
- Cable-Quality
- Connection (DC-Jack)
With 12V@1.5A you won`t be able travel long distances.
But the main limiting factor isn`t the Cable but the 5.5mm Jack.
1. I wasn`t able to find any DC-Jack for thick Wire (>0.5 mm²)
2. DC-Jack have "relatively" high resistence
I don`t see any problem with a cable up to 3 m.
If you want to push the limits maybe 4 or even 5 m will work...
But i wouldn`t go any longer.
Problem 3: Efficiency of device
I don`t own a hAP ac³ , so i can`t confirm this...
But I am very sure, the lower the Input-Voltage, the higher the Efficiency.
So for exemple 12V should be more efficiant then 28V
