Wi-Charge products comply with applicable international safety standards and regulations. The products have been tested and approved for introduction into commerce.
We do not use RF or ultrasound. We use infrared light – similar to remote controls and computer mice.
What’s the big difference?
RF, microwave, ultrasound – are all “man-made” types of radiation, byproducts of the industrial revolution. They didn’t exist 150 years ago, and the human body isn’t known to biologically adapted to any of them. As a result, they’re known to be harmful even at relatively low intensities, and their mechanisms of impact on human tissue are still being studied (meaning that one day we might find out they are even more harmful than we currently think).
Infrared, on the other hand, is natural radiation. It accounts for 50% of sunlight and has always been part of Earth ecosystem. All life of Earth is biologically adapted to it, so it is benign even at relatively high intensities.
To put this in numbers, infrared is 500 times safer than RF and 3000 times safer than ultrasound.
The applicable international standard is IEC 60825-1 Safety of Laser Products. Our products comply with this standard as Class 1 laser products (safe under all conditions of use and exempt from any protective measures). IEC 60825-1 compliance report by SII (an accredited certification laboratory) can be found here.
Compliance with IEC 60825-1 standard is a necessary and sufficient technical requirement by national regulators in nearly all countries. The US being an exception, we obtained a specific approval from the FDA (the US federal safety regulator).
Infrared-emitting products (like Wi-Charge) are regulated by the FDA, and are not subject to FCC regulation.
The Food and Drug Administration (FDA) is the US federal agency responsible for public health protection. This includes regulation of food, drugs, tobacco, medical devices, and radiation-emitting products. Our products fall under the last category.
The Federal Communications Commission (FCC) is the US federal agency regulating wired and wireless communications. As such, any radio-emitting product must comply with FCC regulations.
To prevent the complication of the same products being regulated by two different agencies (FDA for safety, and FCC for spectrum licensing and interference) the FCC also assumed the public safety aspect for radio-emitting products. This is the source of the confusion.
