I’m looking for higher-power NFC wireless charging reference designs.

    I tested an NFC wireless charger for tiny devices that outputs 5 V/45 mA on the receiving end with ~33% efficiency. Does anyone know higher-power NFC charging solutions I can reference?

    Based on the question, an electric induction hob works on the same principle, only the parameters of the electromagnetic field are different.

    Kind regards

    NFC is a communication method; it can barely power a simple data-receiving circuit in a contactless card – compare this with Qi, which is used for charging and has a higher power output.
