With the iPhone 8 series and iPhone X mobile phone launch, Apple's first in its smart phone products to join the wireless charging function. Although the wireless charging feature can be compatible with the Qi standard, but did not meet people's expectations. Earlier news that Apple will launch a new technology this year, allowing the iPhone to achieve remote wireless charging, without the need to use the charging board.
Although Apple did not achieve the wireless charge to get rid of the charge board bound, but the California-based start-up company Pi realized. The company uses a tapered desktop device Pi Charger, combined with Qi-based resonant sensing and a special beamforming algorithm, allowing it to charge multiple devices in any direction.
Pi Charger may not be able to meet the range claimed by Energous to WattUp Technologies, which uses radio frequencies to allow the device to charge wirelessly from 15 feet (4.6 meters) away, but Pi Charger is more flexible than existing charging boards Need to be in direct contact to charge.
"The magnetic field is the best way to transfer energy to mobile phones, tablets and other portable electronic devices," said Lixin Shi, chief technology officer and co-founder of the start-up company. "The difficulty is how to make the magnetic field more flexible and expand the effective range. "
It is understood that this product can be up to four devices at the same time wireless charging, the effective range of 12 inches (about 30 cm). The closer the phone is to Pi Charger, the faster the charge is. The company said the current Pi Charger has not yet developed a specific price, but is expected to be sometime next year to enter the market, the price will be less than 200 US dollars.
There are rumors that Apple has reached an agreement with Energous and plans to provide a truly wireless charging technology for its consumer devices, but we may have to wait for some time to see it coming. And before the arrival of the new technology, you can try to use Pi Charger to the upcoming new iPhone charge.
