Why choose conductive charging over inductive charging?Conductive charging has a few clear advantages over inductive charging. It's alignment-free, more efficient, and can deliver up to 140W of power without the heat or energy loss that typically comes with inductive systems. As an added bonus, conductive charging is also low noise and therefore safer for use in sensitive electronics or those deployed in rugged environments. Power by Contact uses conductive technology to deliver a dependable wireless charging experience with fast charging speeds, total freedom of placement, and maximum efficiency.
-
Do I need to redesign my products to make them Power by Contact compatible ?No. Power by Contact's compact receiver can easily integrate into most existing product designs without major changes. Additionally, external USB Type-C adapters make it simple to retrofit your current devices, allowing you to take advantage of wireless charging with minimal modifications.
-
Are Power by Contact technologies protected with intellectual property ?Yes. Power by Contact is protected by a range of intellectual property (IP) rights, including international patents, trademarks, and proprietary reference designs. For companies looking to integrate Power by Contact into their next innovation, we offer licensing opportunities and support to ensure proper implementation while respecting the IP rights.
-
Is Power by Contact technology safe for my batteries?Yes. Power by Contact is designed to work alongside your device’s original charging standard and protocols, ensuring full compatibility. It’s compliant with USB-C Power Delivery, which makes it suitable for a wide range of batteries. In addition, Power by Contact includes multiple layers of protection and charge monitoring, ensuring that your battery receives the precise amount of power it needs - safely and efficiently - while preventing overcharging or damage.
-
What happens if a liquid or a conductive object is put on the charging surface ?Power by Contact’s foreign object detection system will stop the charging immediately if a foreign object is detected on active tiles.
-
Is Power by Contact certified ?Power by Contact simplifies the certification process. Since it doesn't use induction, its electromagnetic emissions are minimal, which makes it easier to meet regulatory standards. Customers have successfully received CE, FCC, and other equivalent certifications when integrating Power by Contact™ into their products, ensuring compliance with global safety and performance standards.
-
Is Power by Contact durable?Power by Contact is built with durability in mind.
