New wireless charging regulations take effect today: power limit relaxed to 80W
it was learned from the official website of the Ministry of Industry and Information Technology that the “Interim Provisions on Radio Management of Wireless Charging (Power Transmission) Equipment” issued by the Ministry of Industry and Information Technology in May 2023 will officially come into effect today.
From the date of implementation, the production or import of wireless charging devices that do not meet the requirements for sale and use in the country will be stopped. Wireless charging devices produced or imported before this date can continue to be sold and used until they are scrapped.
This means that after the new regulations come into effect,
the restriction on wireless charging power of mobile devices not to exceed 50W set in 2021 will be relaxed to 80W. Flagship mobile phones in the second half of this year are expected to be equipped with wireless charging power of up to 80W.
It is understood that in 2021, the Ministry of Industry and Information Technology issued the “Interim Provisions on Radio Management of Wireless Charging (Power Transmission) Equipment (Draft for Comments)”.
Article 4 clearly states that mobile and portable wireless charging devices should operate in the 100-148.5kHz, 6765-6795kHz, and 13553-13567kHz frequency bands, and the rated transmission power shall not exceed 50W.
It is precisely because of the introduction of this regulation that the competition among domestic Android mobile phone manufacturers in the field of wireless fast charging has come to an end. The maximum wireless fast charging power of all flagship mobile phones launched subsequently can only reach 50W.
