Features Of Wireless Sharing Of Mobile Phone Power
It is a move that will not only improve the standards of wireless charging technology but will also drive the industry towards a universal standard and in the process likely increase the adoption of it. Turning it from a fairly niche technology to something which could one day outright replace wired charging.A Taiwanese company is demonstrating two-way touch charging in this week at the Computes exhibition. Using a new chip that allows two people to share one phone’s battery by holding their devices together. In a demonstration two iPhone’s with external battery packs containing the chips were pressed together back to back. One phone was used to charge the other, then after the settings on the external batteries were switched, power flowed in the opposite direction.
Wireless charging gives you a lot more freedom with your device. Rather than being chained to a cable you can just put your phone or other device on a charging surface. No more searching for your charger or fiddling around plugging it in. Longer term it could also mean wireless charging abilities being built into tables and desks. So simply putting your phone down on them will charge it.There are three wireless charging standards, Power Matter Alliance, Alliance for Wireless Power and the Wireless Power Consortium’s Qi and the former two have now teamed up.Previously any wireless charging solution would generally only be certified for one of those standards, but now it will be possible for them to incorporate technology from both PMA and A4WP. This innovative solution could help people easily recharge mobile or wearable gadgets, particularly for tasks such as emergency phone calls added.In experiments, Power-shake fit into small devices, met wireless power transfer safety guidelines and performed about as well at power transmission as commercial alternatives, such as the Qi wireless charging pad, transferring about 3.1 watts of power, the researchers said. They estimated that about 12 seconds of charging would support 1 minute of additional talk time, while 2 minutes of charging would support about 4 minutes of video watching.One drawback of Power-shake is that twice as much energy needs to be transmitted as is received.
