Wireless Power Supply

The Seeed Wireless Power Supply is a power transfer devise which can be used for close wireless charging or power supply. The module is composed of transmitter (black) and receiver (white) . The transmitter module runs off a 12Vdc power supply and uses the principle of electromagnetic induction to transmit converted power to the receiver module. The receiver module receives the power supply and outputs a stable 5Vdc at 300mA.


  • Wireless charging or power supply
  • Output stable 5V direct current
  • Slim components
  • Easy-to-use
  • Easily added to electronic projects
  • Low heat dissipation

Application Ideas

  • Robot charging station
  • Wireless sensors
  • Mobile phone charging
  • Non-contact applications
  • Wireless Seeeduino power supply
  • Electronic magic tricks


  • Input voltage: 12Vdc
  • Output voltage: 5Vdc
  • Output current: 300~400mA
  • Transmitter module: 5mm*45mm*60mm
  • Receiver module: 2mm*40mm*55mm


  1. Can’t be used to charge or supply a voltage bigger or smaller than 5V.
  2. Pay attention to the anode pole and avoid connecting the power to wrong pole!
