Introduction
Tech enthusiasts are well aware that Apple made upgrades to both wired and wireless charging with the iPhone 12 series. Wired charging power was increased from the original 18W to 20W. Don't underestimate this 2W change; it had a profound impact on the fast-charging market. After the release of the iPhone 12 series, various manufacturers introduced nearly a hundred 20W fast chargers in about half a year. Furthermore, many high-power multi-port fast charging products have incorporated 20W into their simultaneous output strategies.
In the realm of wireless charging, the 12 series retained compatibility with Qi 7.5W wireless charging while introducing the new MagSafe wireless charging. Whether in terms of charging speed or usage, MagSafe provided users with a satisfying experience. Subsequently, third-party wireless charging products launched in the market were greatly influenced by MagSafe. Even if they didn't use Apple-certified wireless charging modules, they often included magnetic functionality. Currently, there is a wide variety of multi-in-one and stand-type magnetic wireless chargers and magnetic wireless power bank products available.

This year, the Wireless Power Consortium (WPC) introduced the new Qi2 enhanced wireless charging standard. Based on Apple's innovative Magnetic Power Profile (MPP), Qi2 aims to deliver a better wireless charging user experience and pave the way for future feature enhancements. Following this, ChargerLAB and others leaked information suggesting that Apple's upcoming iPhone 15 series will support 15W wireless fast charging.
From WPC statistics, it's evident that the wireless charging market is immensely vast. The implementation of new wireless charging features in the iPhone 15 series signifies a new wave of disruption for the entire market, and the impact of the iPhone 12's influence on the market, as mentioned earlier, is a perfect example.
What is the Qi2 Wireless Charging Standard?
The latest Qi2 wireless charging standard from the WPC, optimized based on Apple's MagSafe, known as the Magnetic Power Profile (MPP) protocol, makes wireless charging more convenient and efficient for users, offering improved compatibility. WPC has standardized and integrated authentication verification, enhancing practicality and convenience while promoting the widespread adoption of wireless charging.
Qi2 certification requires products to include EPP and MPP transmitting areas and must incorporate authentication. Single BPP wireless chargers cannot receive Qi2 certification. In multi-in-one wireless chargers, they can include BPP, but they must include at least one EPP or MPP.
Qi2 certification must pass ATL verification, and there are currently 11 authorized labs in the WPC network.
Qi2 MPP Wireless Charging Module
MagSafe is Apple's proprietary protocol, requiring Apple's authorized MFi certification to achieve 15W fast charging for iPhones. Without certification, even though it can magnetically attach for charging, it remains at 7.5W. This limitation restricts the expansion of the ecosystem. Qi2 MPP upgrades the proprietary protocol to the WPC standard. Through Qi2 certification, it can adapt to Apple's 15W fast charging, significantly reducing end-user costs and allowing more chip manufacturers to foster the ecosystem together.
The MPP module not only replaces traditional MagSafe modules but also reduces wireless charging costs and enhances user experience. It's widely used in wireless charging docks, magnetic power banks, and car mounts.
iPhone 15 Series Adapts to Qi2 Wireless Chargers
On September 12, 2023, the highly anticipated Apple Fall Event unveiled the iPhone 15 series, the new Apple Watch series, and AirPods Pro 2 with USB-C ports.
The brand-new iPhone 15 series not only adopts USB-C ports across the board but also emphasizes support for the new Qi2 wireless charging standard at the event. This means that Qi2-certified chargers can provide up to 15W wireless charging for iPhone 15 models, just like Apple's MagSafe charger. Qi2 chargers do not require Apple's expensive MagSafe module or MFi certification.
Apple's move to support Qi2 is bound to garner significant attention throughout the industry, both upstream and downstream in the supply chain. Some forward-thinking manufacturers have already seized this opportunity and made early strategic investments. According to ChargerLAB's incomplete statistics, companies like ConvenientPower, ESSON Tech, and WPINNO have introduced complete Qi2 MPP wireless charging modules. With these existing solutions and modules, manufacturers can quickly bring their products to mass production and market, gaining a competitive advantage.
