Rezence Magnetic Resonance Charging is The Future of Wireless Power

Rezence is a relatively new technology, and is the consumer-facing brand that represents the group of technologies represented by the Alliance for Wireless Power. There are currently three major wireless power alliances, for those not versed in the world of wireless power. There is the Wireless Power Consortium (WPC) which is responsible for the Qi wireless power standard, the Power Matters Alliance (PMA) and the Alliance for Wireless Power. Each of these organizations believes that they have the right idea about wireless power and there is some overlap between the three, but they are still fundamentally three different organizations. Additionally, many of their most prominent members are actually members of all three, like Qualcomm.

Now, we had an opportunity to meet with Geoff Gordon from Qualcomm, who was representing the Alliance for Wireless Power at the Rezence booth at Mobile World Congress. He took us around their booth and gave us a few demonstrations of how their magnetic resonance charging solution was superior to others. And considering the fact that I currently use Qi heavily, I’m quite familiar with the limitations of inductive charging. What was prominently displayed at their booth were a few demos from Qualcomm, Gill Electronics, Samsung Electro-Mechanics and Samsung Electronics as well as IDT and WiTricity.

Geoff gave us a great demonstration of the technology in action and we managed to get a great idea of how much better magnetic resonance charging really is.
