If you click on the green light bolt that is the symbol of the joker it will show you - “reduces energy consumption by 10%” - meaning:

When you visit a friend’s room (not trophies or crafters) it reduces the energy they will need to spend to play that room. Example: if I have to spend 100 energy to play a room, when you charge it I would only have to spend 90 energy. This affects only 1 time a day and lasts only 2 days but for high level players that play more expensive rooms with talismans this is big help. The further away you move from the middle of the map, the more expensive the rooms get usually.
