I'm currently using an MFSU. I tried to give some of my friends energy so they can use it too, but after some metres ( about 45 blocks ) there's no electricty more so the cable doesn't come to their home because they'rer a bit far away.
Is this a bug? Because my English is so bad I tried to do a video to make it more "understandable":
And if that's not a bug, how can I do it anyway so that my friends get their energy?
