Why Top-Produkte exists
When buying a device, the price usually takes centre stage. What using it costs over the years, and which technical details really matter, is harder to see. Top-Produkte aims to make that easier to understand.
What we do
- Calculators that show what running a device can cost.
- Explanations of which details matter for a decision.
- Comparisons that set options side by side using stated criteria.
- Ideas for saving energy and money in everyday life – without marketing promises.
We are starting with the topic Energy & Living and the electricity cost calculator.
How we work
We work with published data and sources, make formulas visible and keep facts and assessments apart. The details are on the Methodology & Sources page.
What we do not claim
- We do not imply our own physical product testing where none has taken place.
- Our calculators give estimates – not measurements and no guarantee for your electricity bill.
- Our comparisons are not an absolute ranking; they apply to the criteria and use cases stated.
- Our content is no substitute for individual advice.
Affiliate links
Some older content may still contain affiliate links. Top-Produkte currently does not use any active affiliate programs. More under Transparency (German).
