Wireless Power Technology

PROXIMITY POWER IS EFFICIENT AND SAFE

Short distance power transmission is usually based on the principle of magnetic induction. With this technology, power is transferred only if the receiver is close to the transmitter. The technique of magnetic induction was discovered more than a 100 years ago. It has been used for decades in all kinds of electronic equipment. Why? Because it is simple, efficient, and safe.
