What is the difference between Qi2 and Qi?
In 2023, the Wireless Power Consortium (WPC) introduced a new wireless charging standard—Qi2. Compared to Qi, Qi2 offers several upgrades, including faster charging speeds, more precise magnetic alignment, and improved cross-system compatibility. Previously, iPhones could only charge at 7.5W using Qi wireless chargers, while 15W charging was only possible with Apple-certified MagSafe chargers. Now, with the Qi2 standard, both iOS and Android devices can use the same magnetic charging equipment, ensuring precise alignment and enjoying up to 15W charging speed.
How Wireless Charging Works
Wireless charging fundamentally relies on electromagnetic induction to transfer energy. It requires a charger equipped with a transmission pad (TX) and a device with a built-in receiving pad (RX). The transmission pad (TX) generates an AC magnetic field at a specific frequency. When the two coils are close to each other, the receiving pad (RX) captures the magnetic energy and converts it into electrical energy through the principle of electromagnetic induction, ultimately charging your device.
Advantages of Qi2: More Powerful Than MagSafe
The Qi2 standard is built on Apple’s MagSafe technology and incorporates the Magnetic Power Profile (MPP), which not only makes magnetic wireless charging more precise in alignment but also reduces magnetic field leakage caused by misalignment, thereby minimizing heat generation and ensuring optimal charging efficiency. Qi2 also breaks the limitation of MagSafe being exclusive to Apple products. Now, as long as you purchase a wireless charger with the WPC-certified “Qi2” logo, all Qi2-supported phones and devices can enjoy the next generation of wireless charging. Products from different brands are compatible with each other, reducing the need for repeated purchases.

Future Prospects of Qi2
Qi2 not only retains the advantages of MagSafe but also offers higher charging efficiency, more convenient magnetic alignment, and broader applications! In the future, Qi2’s charging power is expected to increase to 50W, supporting more devices. As this technology becomes more widespread, it will provide users with a more effortless and convenient charging experience.
Innergie’s latest magnetic wireless charging charger and magnetic battery pack adopt the Qi2 standard and have been officially certified by WPC. Whether you are an Apple iOS or an Android user with Samsung, Huawei, or other devices, as long as your phone supports Qi2, you can enjoy up to 15W wireless charging!
