Wireless power alliance New Standard: wireless charging for computers

Although wireless charging sounds good, devices that can use this technology are still very limited. The good news this week is that Alliance for Wireless Power (A4WP) the new standard has expanded the power range supported by wireless charging from 3.5-16 watts to 1-50 watts. This means that the devices supported by wireless charging devices will no longer be limited to smartphones in the future. Many tablet devices and even laptops can use wireless charging technology to provide power.

For the wireless charging industry, this new A4WP standard has solved the problem of the applicability of wireless charging devices, after all, up to 50 watts of power support can cover most of the electronic devices we currently have access. However, many users may have several mobile phones and tablets, so wireless charging technology also needs to solve the problem of simultaneous power supply for devices of different power specifications. At this point, A4WP is not ignored-the latest A4WP standard supports both simultaneous charging of multiple devices and power supply of devices with different power supply specifications. This means that wireless charging devices using the A4WP standard will be able to charge the iPhone and Android mobile phones at the same time.

At the end of this year, A4WP is expected to launch and upgrade existing system specifications and certification projects for device manufacturers. As an independent non-profit organization, A4WP aims to make its Rezence technology a standard in the global wireless charging industry, it has also been supported by well-known manufacturers such as Qualcomm, Samsung, and Lenovo.

Just as when a new technology was born, some large companies always come out to snatch the definition right of industry standards, wireless charging is also a promising technology. Currently, in addition to A4WP, the other two competitive standards are Power Matters Alliance and Qi. The supporters behind Power Matters Alliance include well-known companies such as Google, Starbucks, and AT&T, and Qi, the first to start, has received support from many vendors such as Philips, HTC, Nokia, and Samsung.

In June February this year, A4WP and Power Matters Alliance signed a cooperation agreement that will be applicable to charging devices using these two standards. This naturally led to the confrontation between A4WP, Power Matters Alliance and Qi in the wireless charging industry. This is of course a good thing for the development of the industry.

As A4WP upgraded its wireless charging technology standards this week, wireless charging devices are one step closer to normal consumers. Although the competition for standards continues, the technical strength will also be an important factor in the choice of third-party vendors.
