What is Qi2 Wireless Charging?

Qi2, much like its predecessor Qi, is a wireless charging standard that allows devices to charge without the need for pesky cables. It operates on the principle of electromagnetic induction, where power is transferred between a charging pad and a compatible device through magnetic fields.

The Qi2 wireless charging standard was developed by the Wireless Power Consortium (WPC) and represents a significant advancement over the original Qi standard.

Qi2, launching in early 2023, incorporates features inspired by Apple’s MagSafe technology, specifically Magnetic Power Profiles (MPP).

USB 4 is based on Intel's This innovation utilizes a magnetic ring to perfectly align the charging coil, increasing charging efficiency and reducing the risk of overheating.

How does Qi2 work?

Qi2, the next evolution in wireless charging technology, operates on the same fundamental principles as its predecessor Qi but introduces several key enhancements to improve performance and efficiency.

At its core, Qi2 utilizes electromagnetic induction to transfer power from a charging pad to a compatible device without the need for physical connectors. This process involves two main components: the transmitter (charging pad) and the receiver (the device being charged).

Transmitter (Charging Pad): The transmitter, typically a charging pad or mat, contains a coil of wire that generates an alternating electromagnetic field when connected to a power source. This electromagnetic field creates a localized area of energy transfer, commonly referred to as the charging zone.

Receiver (Device): The receiver, integrated into the device being charged, also contains a coil of wire. When the device is placed within the charging zone of the transmitter, the alternating electromagnetic field induces a current in the receiver coil through electromagnetic induction.
