You'd think, 220kW used when there's nothing charging, for power transmissions and upgraded range, better communications, integration with the network.
But this device does none of that: all it does within the network is broadcast a small signal to say "there's a recharger here". It's not even that far. It integrates with the existing network; ie it has to be within the orange space created by other roboport-like-entities. It doesn't create any orange or green space on its own. It helps the communications network zero. It just broadcasts this simple signal, like a gas-station advertisement. "Fuel up here!"
Therefore, 220kW power draw makes no sense at all. It should be far less than what a normal roboport uses, which is 50kW. Perhaps 20 is too much. It made a huge drop in power usage in my factory with over 500 placed, but allowed way more usage during heavy load, (12k uranium ore unload by active provider).
I'm calling this problem fixed, but I'm open to suggestions.
