You heard it right, this is really a wireless doorbell that can transmit wireless signals without batteries. This is a product called Augreener brand. The transmitter uses the world’s most advanced energy capture technology. Technology that can convert the kinetic energy of touching a button into electrical energy, which then drives the transmitter to send out wireless signals. This can be regarded as a revolutionary design. You no longer have to worry about the remote control running out of power and frequently replacing dry batteries, and it also avoids the environmental pollution of used batteries. If this energy-capturing technology can be spread to other products, it will be a blessing for the earth.
