Anytime and anywhere is the outstanding irreplaceability of MSE, which fully meets the energy modernization standard. No other energy source has been found so far to have this feature. The MSE does not charge, but only charges the current of the MSE itself, and the current of the MSE is everywhere, and it can be MSE-charged at any time and place. We say that MSE products do not be refueled or charged, which means that they will not be charged with any non-MSE current of charging piles other than MSE's own current. It is the irreplaceability of MSE that is anytime and anywhere that creates many unique MSE products.
