    Correct, although it’s getting better

    https://en.wikipedia.org/wiki/Inductive_charging#Disadvantages

    Newer approaches reduce transfer losses through the use of ultra thin coils, higher frequencies, and optimized drive electronics. This results in more efficient and compact chargers and receivers, facilitating their integration into mobile devices or batteries with minimal changes required. These technologies provide charging times comparable to wired approaches, and they are rapidly finding their way into mobile devices.

    For example, the Magne Charge vehicle recharger system employs high-frequency induction to deliver high power at an efficiency of 86% (6.6 kW power delivery from a 7.68 kW power draw).

      imo 86% is pretty good. But I’m not an expert on thé topic.

      Although if we could dimish individuall car usage all together that would generate massive energy savings.
