Energy prices will explode in the winter of 2021/2022. It is a good time to optimize the energy needs of your own four walls to reduce costs. Our series of articles focusing on saving energy costs shows how and how this works.

It is said that for only 59 euros per unit, Voltbox can save "up to 90%" of electricity bills. It is said to have achieved this goal through the "pioneering current stabilization technology (EST) with reactive power compensation", which aims to stabilize household current and improve efficiency. Most importantly, it should be exposed to "less artificial electromagnetic radiation (EMF/EMR)". Finally, "sets [die Voltbox] uses advanced capacitors to eliminate harmful surges that can damage your home and appliances."

At least the last point-which is expected-it has been achieved to some extent. An analysis of its internal workings sheds light on why Voltbox crashes. In order to save you from relying on us alone, we have provided a copy to VDE for independent evaluation.

Electrician experts have already seen from the housing that Voltbox does not affect the current of domestic consumers: it does not have Schuko outputs that can be connected to other devices, but is connected in parallel with them in the home grid, so it can only affect the voltage. What sounds subtle to the layman is technically related: In order for the circuit to compensate for the reactive power consumed by the consumer, it must "shape" their current, even if it is more sinusoidal with the non-linear consumer and over time The change over time has complex loads.

Reactive power compensation can be achieved by inductive loads (motors, electromagnets) with parallel capacitors. However, on the one hand they must be too large to fit in the box, on the other hand they must be opened and closed with the consumer. In any case, since 2001, most power consumers who consume large amounts of electricity have to install power factor correction in the factory. In terms of voltage quality, this makes Voltbox redundant for all practical purposes.

In the Voltbox housing, there is a small circuit board with several components and a big black block as a "filter element", which literally means a black box.

After all, reactive power is only calculated for large commercial customers and therefore has nothing to do with private customers. However, Voltbox cannot change the actual strength of domestic consumers, which becomes a paid energy source over time. VDE confirmed this: "The product does not have any features that meet the product promise."

For this reason, Offenbach’s VDE testing and certification agency conducted a test with a high-fidelity amplifier as a consumer. The amplifier consumes a significant non-linear current, resulting in a high proportion of reactive power. Here, Voltbox should be able to perform miracles. But after inserting the box, the system actually consumes more actual power instead of significantly reducing it. The power consumption of 0.3 watts keeps Voltbox's annual electricity bill within a reasonable range, even around one euro. If the device is not helpful for energy saving, then it may have other functions.
