@lunawat123 there can be no gap between charging two EC. But one EC should be charged enough, atleast for 30 minutes, rest depends upon the situation, how much energy is required.
For example EC for a stomach ache would need less time but EC for Total Wealth Energy needs continuos energy.
Same way it doesn’t matter that what is the time gap between charging a bottle of water and an EC. Once water is charged, move to EC. But give 30 minutes to EC and then charge water.
Water is a visible quantity, it can be charged in few rotations. But EC might need more energy so send more energy. I explained it with two examples above.
