The Evolution of Qi Wireless Charging: Introducing Qi2.2
The Qi wireless charging protocol, established in 2010, has made remarkable strides over the past 15 years. Initially limited to a modest 5W output, it has now made a significant leap to commonly offer 15W. While it may not categorize as ultra-fast charging, it is sufficiently speedy to add convenience to users. The recent advent of the Qi2 standard has integrated Apple’s MagSafe technology, allowing for magnetic alignment between chargers and devices. This advancement eliminates the hassle of precise alignment for effective charging.
As of 2023, Qi2 has been firmly established as a standard, with the promise of enhancements on the horizon. The Wireless Power Consortium (WPC), the body responsible for its development, indicated that Qi2’s 15W capability is expected to rise, laying the groundwork for quicker charging solutions. Moving into 2025, the anticipated benefits are materializing with Qi2.2, predominantly seen on iPhones at this time.
The 25W Advantage of Qi2.2
Officially recognized in April, Qi2.2 expands upon its predecessor by enabling power transfer rates of up to 25W while maintaining magnetic connection. When paired with an appropriate cable and power adapter, this increase can significantly enhance charging speeds compared to 15W alternatives. For instance, the latest iPhone 16, when used with Apple’s latest MagSafe charger and a 30W power adapter, can charge from 0 to 50% in just 30 minutes. In comparison, 15W MagSafe would achieve a similar result in approximately 45 minutes. This is quite impressive for a wireless solution.
It’s important to note that the current MagSafe charger operates under the Qi2 standard rather than Qi2.2. As Qi2.2 products start to hit the market, their performance will provide a clearer comparison to Apple’s existing MagSafe solutions. There are even indications that Apple might be developing chargers compatible with Qi2.2.
News suggests that third-party Qi2.2 chargers may soon become available. According to The Verge, several charging devices have been recognized by the WPC for supporting Qi2.2, including:

Scosche MagicMount Pro Charge (alternative version)
Currently, these Qi2.2 products aren’t ready for consumer availability. For instance, UGREEN’s power bank is projected to launch in the fall of 2025. However, it’s encouraging to see firms making progress with this advanced Qi standard. The hope is for a swift rollout of these products alongside increased support for Qi2 and higher from smartphone makers. Apple’s offerings are compatible with Qi2 starting from the iPhone 12, yet only the HDM Skyline currently supports this standard on Android devices.
