Wireless charging, also known as inductive charging, typically utilizes electromagnetic fields to transfer energy between two devices. It commonly relies on specific frequencies that are safe and optimized for efficient power transfer. The most widely used frequency for wireless charging is around 100-205 kHz, known as the resonant frequency, and it is commonly used in technologies like Qi wireless charging.
Using a microwave for wireless charging would not only be inefficient but also dangerous. Microwaves generate a high level of energy in the form of electromagnetic waves, which are specifically designed to heat the water molecules present in food. Trying to use this energy for wireless charging could result in damage to the charging device, inefficient power transfer, and potentially hazardous conditions due to the high power and uncontrolled nature of microwave radiation.
If you're looking for wireless charging options, I would recommend exploring commercially available wireless charging pads or stands that are designed specifically for safe and efficient power transfer. These devices are typically compatible with smartphones, smartwatches, and other devices that support wireless charging technology.
