Multi-function frequency conversion charging device

Abstract

The present invention relates to a multi-function frequency conversion charging device, which mainly includes: a first circuit board; a high-frequency receiver module; at least one power transmission portion; a second circuit board; a low-frequency transceiver module to selectively receive the power initiation of the high-frequency receiver module and wirelessly charge a second electronic device; and at least one magnetic portion for filtering the noise and reducing the interference. The high-frequency receiver module is used to react with the high-frequency wireless charger to produce electricity, and then proceed the wired charging to the electronic device through the power transmission portion if the electronic device has no function of wireless charging; otherwise the wireless charging is proceeded through the low-frequency transceiver module and the interference between the high-frequency and low-frequency transceiver module is effectively isolated by utilizing the magnetic portion if the electronic device just supports the low-frequency wireless charging.
