Battery

— most often, in this case, power is supplied from replaceable elements; it can be not only accumulators, but also disposable batteries. This type of power can only be used in models with a mechanical load system, where the load system itself does not consume electricity; for electromagnets, the power of the batteries is not enough. On the other hand, such models do not depend on outlets; the battery, of course, can "sit down" at the most inopportune moment, but in this case, only the indicators turn off — the simulator itself will remain usable.
