WiFi cordless power, as a mainstream and practical technology, does not exist. The term "WiFi cordless power" might be a bit misleading, as WiFi (Wireless Fidelity) primarily refers to wireless data communication and does not directly transmit power.
However, there are ongoing research and development efforts in the field of wireless power transmission. One of the most well-known methods is called "wireless power transfer" or "inductive charging." This technology allows devices to be charged without the need for physical cords. Inductive charging is currently used in some smartphones and other gadgets, where the device is placed on a charging pad, and power is transferred wirelessly from the pad to the device's battery.
Additionally, there have been experiments with long-range wireless power transmission, such as using microwave or laser beams to send power over greater distances. Still, these methods face significant technical challenges and safety concerns, making them not yet practical for everyday use.
As for the future, it's challenging to predict with certainty, but it's possible that advancements in wireless power transfer technology could lead to more cordless appliances and lighting in homes and other settings. However, the widespread implementation of such technologies would depend on several factors, including efficiency, safety, cost-effectiveness, and regulatory approvals.
Always keep in mind that technology is continually evolving, and new breakthroughs can happen in unexpected ways, so it's essential to stay updated with the latest developments in the field of wireless power transmission.
