The Wireless Power Consortium (WPC) is further expanding the Qi2 standard for wireless charging. With the new version 2.2.1, Qi2 now manages up to 25 watts, the WPC announced on Wednesday. Previously, it was possible to charge with up to 15 watts via Qi2. The new version is referred to as "Qi2 25W".
The WPC is thus raising its standard to the level of Apple's Magsafe technology, which formed the basis for Qi2. In addition to Apple's iPhone, Android smartphones from other major manufacturers are now set to support the standard. The first devices have already been certified and hundreds more are still being tested, according to the WPC. The first devices are expected to come onto the market in the coming months.
Qi2 is the further development of the Qi standard originally introduced in 2010, which was announced at the end of 2023 and was initially able to charge with up to 5 watts and then also process 15 watts. Qi2 was also initially designed for up to 15 watts, but the new version is now 25 watts.

"Fast and efficient"
Paul Struhsaker, Executive Director of the WPC, said that it was clear from the market launch of Qi2 that the technology would be suitable for even faster and more efficient wireless charging. "Qi2 25W's remarkably fast and efficient wireless charging will drive the adoption of wireless charging and accelerate the uptake of the new standard."
It took a while for Qi technology to catch on. The Palm Pre smartphone launched in 2009 could already be charged wirelessly. However, the standard only became more widespread in 2012 with Google's Nexus 4 and Nokia's Lumia 920. According to the WPC, there are now over one and a half billion Qi2-certified devices on the market worldwide.
Also in the kitchen
The Wireless Power Consortium was founded in 2008. In addition to Apple, over 300 international companies belong to the consortium, including the German members Bosch, Infineon and Mercedes Benz. In January, the WPC presented its "Ki" standard for the power supply of kitchen appliances at the CES in Las Vegas.
