Today, Motorola officially showcased its long-distance charging technology. Jin Jie, General Manager of Lenovo’s China Mobile Business Unit, stated that this charging distance can far exceed current contact-based charging using Qi technology. It supports charging multiple phones simultaneously and offers safety features, making it a true wireless charging solution.
He also asked everyone about their needs. This technology is expected to be added to future Motorola Edge series.
The video shows that when two Motorola Edge phones are 1.8 meters apart, both phones can charge. When a hand blocks the charging transmitter, both phones stop charging. After removing the hand, the phones start charging again.
It is reported that as early as 2017, the technology company uBeam demonstrated its wireless charging technology for the first time, claiming to have developed a technology that converts ultrasound into electrical energy.
According to reports, the power generation principle is that the uBeam device emits ultrasonic waves, which drive a piezoelectric crystal in a piezoelectric transducer to vibrate to generate electricity. Within 15 feet (about 4.5 meters), it can charge phones and other devices.
