13.56MHz (NFC) Wireless Charger Modules our 13.56MHz wireless charger module is designed for small sensors and wearable devices. It realizes wireless charging of ultra-small devices, which is complicated with the Qi standard. Since 13.56MHz is the same frequency band as the NFC communication standard, it is possible to share the antenna for power supply and NFC communication. Using the power transmission and the power reception modules that have been adjusted for antenna design and matching as a pair, the development of person-hours for antenna design and matching adjustment can be significantly reduced.
In addition to power and compatibility, when choosing a wireless charging module, you must consider the safety, charging distance, and power-saving performance. This module has protection functions such as metal foreign object detection(FOD), over-voltage protection(OVP), over-temperature protection(OTP), and over current protection(OCP). When any of the above abnormal conditions are detected, the module will stop supplying power and ensure safety. The maximum charging distance is 6 mm, so the smartphone is a phone case that you can still charge. The module has the excellent power-saving capability, providing 78% maximum power transfer efficiency and t 50 - 200mW standby power consumption.
Qi charging is already compatible with the latest models of smartphones, such as the iPhones13 and the Samsung Galaxy S22. As newer models become available, they will also have a Qi wireless charging function.
Some phone cases (such as wallet cases) might be too thick for wireless charging to work correctly. Cases made of plastic, silicone, rubber, and leather don’t seem to affect wireless charging too much.
Wireless chargers are rated by output in watts. Most current chargers provide around 5W, with a few capable 10W–15W. Used to charge an iPhone 13 or Galaxy S22, for example:
Wireless charging technology has been widely used in various products, such as mobile phones, furniture, automobiles, etc. Qi is an open, universal charging standard created by the Wireless Power Consortium (WPC). Compliance with standards allows for better interoperability and security for wireless charging products. This product is a Qi-compliant 5-watt (5 volt / 1 amp) wireless charging transmitter module. It can directly charge mobile phones with a wireless charging function. It can also charge the receivers that are compatible with the Qi standard but will not charge for receivers that are incompatible with the Qi standard.
Smartphones are built to prevent their batteries from being overloaded. If you leave your phone to charge overnight, it will reach 100% capacity and stop, although it will continue to top up the battery every time it falls to 99%. This can shorten the battery’s lifespan somewhat.
You can use any wireless charger with your smartphone if they support the same wireless charging standard (e.g., Qi). They don’t need to be made by the same manufacturer—you can use a Samsung wireless charger with an iPhone, for example.
