Xiaomi Debuts World’s First 30W Wireless Charging Technology 2nd Opinion September 10, 2019 News, Tech Xiaomi recently introduced four new major breakthroughs in the wireless charging industry, including the world’s first 30W fast wireless charging device with high power reverse-charging capabilities. The Mi 9 Pro 5G will sport this technology soon, along with two brand new wireless charging accessories. Xiaomi also announced it will be forming a wireless charging alliance with cross-industrial leading companies to further promote wireless charging in everyday life settings. Additionally, the brand also showcased its 40W wireless charging technology, which is already in-test, leading the wave of charging technology innovation and aiming to empower the 5G era. The new 30W wireless charger includes a 4:1 direct-charge architecture, high power wireless reverse-charging technology, a more secure and stable dual band transmission technology, and a universal combination of wired OTG reverse-charging and high-power wireless reverse-charging. Providing a higher efficiency for wireless charging in all kinds of situations. Compared to the previous 20W wireless charging 2:1 direct-charge architecture, the new 4:1 direct-charge architecture utilizes two levels of charge pump voltage reduction. This new architecture further improves efficiency while reducing the heat produced during charging, making it the best single-battery direct charge technology on the market right now. The 30W Fan-cooled Wireless Charging Stand can charge your 4,000mAh battery can charge your phone up to 50% in about 25 minutes, and fully charge it in 69 minutes. Its dual band transmission technology also utilizes Bluetooth. Compared to the communication protocol of the original Qi standard, which combines data and power transmission, dual band transmission technology separates the power transmission from the data communication. It also uses the mobile device’s Bluetooth function to transmit data, which greatly reduces the chance of disconnecting while in wireless charging mode and improves stability, with some additional benefits like transmitting time and battery percentage information between devices. The Mi 9 Pro 5G supports four types of charging: wired fast charging, wireless flash charging, wired OTG reverse charging, and wireless reverse charging. This versatile combination lets you charge your devices whenever, and wherever. When your phone is using wired fast charging, you can also use its wireless reverse charging functionality to charge other phones or earphones that support wireless charging; or supply power to other devices through wired OTG while it is using wireless flash charging. Other Charging Accessories Xiaomi also introduced two brand new wireless charging accessories—the 30W Fan-cooled Wireless Charging Stand and 20W Smart Tracking Wireless Charging Pad. The 30W Fan-cooled Wireless Charging Stand sports an ergonomic design, which allows for optimal viewing and operating while charging wirelessly. It features a vertical air duct design that allows the air outlet to blow directly to the phone to reduce obstructions, improve heat dissipation, as well as reduce the dust trapped in the air duct. The 20W Smart Tracking Wireless Charging Pad elevates the wireless charging experience by automatically tracking and aligning its charging coils to a user’s smartphone. Its dual band transmission technology displays the receiving smartphone’s charging status and time while charging wirelessly. Leading the charging industry trend In the recent years, Xiaomi has continued to make many breakthroughs in the high-efficiency charging field for both wired and wireless technology. In wireless charging, Xiaomi has continued to gain even more momentum with Mi MIX 2S being the first domestic mobile phone to support wireless charging. Following this, the Mi Wireless Charging Pad was released at a very affordable price point of only RMB 99 which reduced the cost of wireless charging for customers. Now, the Mi 9’s 20W wireless charging is still the highest powered wireless charging solution in the industry, and has also received safe wireless charging certification 2.0 from TÜV Rheinland. Xiaomi is a drafting member of the two national standards for wireless charging, a full Member in the WPC Wireless Charging Alliance, and has obtained dozens of patents in the wireless charging field. An even higher-powered 40W Xiaomi high-efficiency wireless flash charging technology is already in the beginning testing phase. With the arrival of the 5G era, where transmission modes are to be transformed, wireless charging will become the industrial trend and eventually replace the current wired charging technology. While the ultimate goal is to provide an accessible and seamless charging experience, Xiaomi, along with its smart home brand MiJia, has teamed up with several industry leaders to form a wireless charging alliance. The new alliance will further expand and integrate wireless charging into everyday life scenarios. The on-the-go charging experience will bring convenience to all and change the way of living, as well as accelerate the evolution of wireless charging while embracing the 5G era.
