The Qi2 Standard
Qi2, the latest standard developed by the Wireless Power Consortium (WPC), introduces Magnetic Power Profile (MPP) to ensure precise alignment between chargers and devices, enhancing energy efficiency and enabling faster charging. Initially supporting 5 W wireless charging with plans to expand, Qi2 promises safe and convenient charging for Android smartphones, wireless earbuds, and more, fostering an ecosystem of accessories with reliable charging capabilities.
To address quality concerns, the WPC is intensifying evaluation of non-Qi Certified technologies. Their review exposes numerous recalls of “Qi Compatible” devices, highlighting the need for stricter standards. The Qi2 standard implements a rigorous certification process for manufacturers via stringent monitoring and enforcement system(s) which deter unauthorized modifications or cost-cutting measures. Qi2 Certified products will display the official logo, ensuring authenticity and safety to protect consumers from counterfeit and hazardous alternatives. Unifying the industry under one global standard, Qi2 simplifies the wireless charging landscape for consumers and OEMs.
What is Qi2 Wireless Charging?
Qi Wireless Charging is the prevailing wireless charging method due to smartphone adoption in 2012. Qi Wireless Chargers use inductive wireless power transfer between the transmitter (the charger) and receiver (the device). Qi Wireless Charging allows for the removal of cords and contact points, resulting in a portable, interoperable, reliable, and fully-sealed product that can be powered individually or simultaneously within a multi-bay system. WPC’s Qi2 implementation of MPP advances the standard by ensuring precise alignment between chargers and devices, enhancing energy efficiency and enabling faster charging.
Custom Low Frequency
Qi2, the latest standard developed by the Wireless Power Consortium (WPC), introduces Magnetic Power Profile (MPP) to ensure precise alignment between chargers and devices, enhancing energy efficiency and enabling faster charging. Initially supporting 15 W wireless charging with plans to expand, Qi2 promises rapid and convenient charging for Android smartphones, wireless earbuds, and more, fostering an ecosystem of accessories with reliable charging capabilities.
To address quality concerns, the WPC intensifies evaluation of non-Qi-certified technologies. Their review exposes numerous recalls of Qi-compatible devices, highlighting the need for stricter standards. The Qi2 standard surpasses its predecessor by implementing a rigorous certification process for manufacturers, implementing stringent monitoring and enforcement system, deterring unauthorized modifications or cost-cutting measures. Products meeting Qi2 standards will display the official logo, ensuring authenticity and safety, protecting consumers from counterfeit and hazardous alternatives. Unifying the industry under one global standard, Qi2 simplifies the wireless charging landscape for consumers and retailers alike.
What is Qi Wireless Charging?
Qi Wireless Charging is the most popular wireless charging method and is best known for its wireless phone charging application. Qi Wireless Chargers use a resonant inductive coupling between the sender (the charging station) and the receiver (the device) to charge or power devices. Wireless charging removes ports and contact pins, resulting in a portable, interoperable, reliable, and fully-sealed product powered individually or with a multi-bay system. WPC’s Qi2 implementation of MPP advances the standard by ensuring precise alignment between chargers and devices, enhancing energy efficiency and enabling faster charging.
