There're two personal roboports MK2 in my power armour inventory, supplying 50 robots. Scratching whole forests from the map or placing large fields of refined concrete gives the robots a lot of work to do, so they need to recharge several times until all is done and they can come "home". The operational field size is 56x56 if that's important.

While they recharge, they use only one roboport; often, many robots are waiting for charge. I can watch the recharge process by opening the armour inventory and hover over the roboports to see their energy level. The first found in inventory is drained while the second stays at 100%, even if the first's energy is depleted.

If it runs completely out of energy, the robots need to wait. Additionally, the recharge time could be halved if both ports would be used simultaneous so twice the amount of robots can recharge. This would also minimize the probability that one or both are drained completely, provided that sufficient energy is available (no problems with batteries).

What you're seeing isn't "using only one roboport"; rather it's "using energy from only one roboport". Look at how the charging robots are clustered around you, and compare that to how it looks after removing one of the roboports. If you can acquire 4 or more roboports, and then remove all but one of them, it'll be even easier to see the difference.

Assuming you're right why is only one roboport drained and not the one a robot is currently using?

The bots are clearly using all 8 charging ports.

Thanks for changing the topic, it's now much more precise.

Thanks for the report. I made some tiny improvement here for 1.1.77 so it should discharge roboports equally if possible, but if some roboports are empty it may discharge other roboports more or go into fallback discharging. That however should not be a problem in most cases.
