The IQ symbol on the USB interface represents the intelligent recognition function. Specifically, IQ refers to the ability of a device to intelligently recognize connected charging devices and adjust the output current based on the recognition results to provide the most suitable charging mode. This intelligent recognition function helps to protect charging devices, avoid damage caused by current mismatch, and also improve charging efficiency and safety.
For example, on mobile power banks such as power banks, the IQ logo is often combined with fast charging technology, which can automatically adjust the charging current and voltage according to the connected devices (such as phones, tablets, headphones, etc.) to achieve fast and safe charging. For low current devices such as headphones, using a portable power bank with an IQ tag for charging can avoid device damage caused by excessive current.
The IQ mark on the USB interface is an important intelligent recognition function that provides users with a more convenient, efficient, and secure charging experience.
