Qi 2.2: The Future of Wireless Charging

Qi 2.2: de toekomst van draadloos opladen

Innovation is happening fast in the world of wireless charging. In a short time, we’ve gone from 7.5 watts to 15 watts, and now it looks like 50 watts of wireless charging is coming sooner than expected. A member of the Wireless Power Consortium (Anker) recently posted about the latest version of the Qi charging standard.

Qi 2.2 is introduced in it, while the Wireless Power Consortium itself has not yet released anything about this. It is stated that we can expect phones and accessories that support Qi 2.2 later in 2025. But what is Qi 2.2, what can you do with it, and how does it work? In this blog, we will delve deeper into this.

What is Qi 2.2 and how does it work?

Qi 2.2 is the successor to Qi 1 and Qi 2 – wireless charging standards managed by the Wireless Power Consortium. This charging standard guarantees a certain charging speed and safety. Qi 2.2 is a big leap forward compared to its predecessors. Qi 1 supports up to 15W (for iPhones even up to 7.5W), while Qi 2 has increased this uniformly to 15W for all smartphones.

Qi 2.2 changes that with a potential charging power of no less than 50W. That is a huge improvement. Some phones, such as the newer iPhones, do not even reach that power via a cable. Qi 2.2 chargers will also have a magnetic design, so that your device always lies correctly on the charging coil. They are also backward compatible with older Qi standards. In theory, you could soon have a wireless power bank that can charge your phone with 50W.

Is Qi 2.2 faster than MagSafe?

For now, MagSafe is slower than Qi 2.2. MagSafe is based on the Qi 2 standard and currently supports a maximum of 25W (only on the iPhone 16). That is half the promised power of Qi 2.2. When more manufacturers start using Qi 2.2, it is likely that Apple will follow suit. After all, Apple is already leading the way in the field of wireless charging.

What is the difference between Qi 2 and MagSafe?

MagSafe is Apple's own charging standard, based on Qi 2. Technically, there are few differences: you can use a MagSafe charger for other Qi 2-compatible phones. The only real difference is that Apple's MagSafe charger can deliver up to 25W, and that's only with the iPhone 16. Standard Qi 2 chargers max out at 15W.

Which phones support Qi 2.2?

At the moment, no phone supports Qi 2.2, because this standard is still in development. The Wireless Power Consortium has not yet announced anything official about this. However, some manufacturers, such as Google, have shown interest. They want to be at the forefront of wireless charging with the Pixel series.

Samsung has already developed a chip that supports Qi 2.2, and thus also enables 50W wireless charging. They claim an efficiency of 98%, which is exceptionally high. In practice, this will be slightly lower.

Conclusion

Qi 2.2 is a huge step forward in wireless charging. However, there are no phones or other devices that support it yet. It will be interesting to see which phones will support it first. For now, it seems to be Samsung, because they already have a chip ready to support it.
