Its really not that bad.

5v at half an amp across a 1mm thick conductor (17/18AWG) only loses about 4% voltage for every ten meters. Much less for thicker.

Ah - I was working on the basis of 20A (using a 100W switching power supply) - Forgot that it was powering 300 LEDs as well as the Pi Zero...

The drop for that is over 50%, bu obvs not very relevant...

I got it wrong too...a half amp rating is not relevant to a pi that can draw more than an amp! Efficiency drops with higher current. Either way, it's not the best solution to run long cables to a 5v device!
