Samsung is the pioneer of wireless charger for smartphones, LG and Nokia also have several models equipped with qi standard receivers. iphone new 8, 8 plus, x support direct wireless charger, but for the previous iphone 7 and older models, we need to install an additional wireless charger receiver. While we are enjoying wireless technology, wireless charging is already very convenient, but we still need wireless transmission faster and faster. As an industry pioneer, Samsung Electronics is the first to release a fast wireless charging pad for the hot-selling model Galaxy S6 Edge Plus. Since then, all Samsung's high-end models have supported wired fast charging and qi wireless fast charging. Compared with the standard wireless charger board, fast wireless charging can reduce less time. Especially when the mobile phone supports fast wireless charging, the charging time can be as short as 1.5 hours. iPhone 8, 8 plus, and x support 5W normal wireless charging, and the charging speed is limited by Apple's power management preset. But one day soon, the charging speed will increase, since Apple equipped its new iPhone with a full-capacity charging speed. Fast wireless charger requires higher rate power input, 9V/1.65 A is the standard level, fast charging USB cable is also very important! What Is Qi And How Does Qi Wireless Charging Works? Qi (Standard). Qi, is an open interface standard developed by the Wireless Power Consortium for inductive charging over distances of up to 4 cm (1.6 inches). The system uses a charging pad and a compatible device, which is placed on top of the pad, charging via resonant inductive coupling. Mobile device manufacturers that are working with the standard include Asus, HTC, Huawei, LG Electronics, Motorola Mobility, Nokia, Samsung, BlackBerry, and Sony.According to a list of Qi devices by Qi Wireless Charging, July 14, 2016 there were over 140 smartphones, tablets and other devices which can be charged wirelessly with Qi. Features and specificationsUnder the Qi specification, "low power" for inductive transfers denotes power deliveries below 5 W. Systems that fall within the scope of this standard are those that use inductive coupling between two planar coils to transfer power from the power transmitter to the power receiver. The distance between the two coils is typically 5 mm. It is possible to extend that range to at least 40 mm. Regulation of the output voltage is provided by a digital control loop where the power receiver communicates with the power transmitter and requests more or less power. Communication is unidirectional from the power receiver to the power transmitter via backscatter modulation. In backscatter modulation, the power- receiver coil is loaded, changing the current draw at the power transmitter. These current changes are monitored and demodulated into the information required for the two devices to work together. The WPC published the Qi low-power specification in August 2009. The Qi specification can be downloaded freely after registration. In 2011, the Wireless Power Consortium began to extend the Qi specification to medium power. The low-power specification delivers up to 5 W (typically used to charge mobile devices), and the medium-power specification will deliver up to 120 W (typically used to power displays and laptops). In 2015, WPC demonstrated a high-power specification that will deliver up to 1 kW, allowing the powering of kitchen utensils among other high-power utilities. System OverviewDevices that operate with the Qi standard rely on electromagnetic induction between planar coils. A Qi system consists of two types of devices-- the Base Station, which is connected to a power source and provides inductive power, and Mobile Devices, which consume inductive power. The Base Station contains a power transmitter that comprises a transmitting coil that generates an oscillating magnetic field; The Mobile Device contains a power receiver holding a receiving coil. The magnetic field induces an alternating current in the receiving coil by Faraday's law of induction. Close spacing of the two coils, as well as shielding on their surfaces, ensure the inductive power transfer is efficient.We provide wireless chargers, if you want higher quality wireless chargers, we can also produce them.
