Many devices, such as smartphones and wireless earbuds, have become compatible with wireless charging. Among them, **Qi2** has been attracting particular attention recently.
Qi2 is a new **wireless charging protocol** that significantly advances conventional **wireless charging**, offering many benefits such as precise alignment through magnetic adsorption, high charging efficiency, and improved safety.
This article will explain Qi2 in detail, from its basics to differences from conventional standards, benefits, and how to choose compatible products. We will also introduce the features of **PISEN** products that offer Qi2-compatible accessories.
What is Qi2? Understanding the Latest Wireless Charging Standard
Qi2 is the next-generation wireless charging standard developed by the Wireless Power Consortium (WPC).
Developed based on the conventional Qi standard, it adopts **Magnetic Power Profile (MPP)**, inspired by Apple's MagSafe technology.
This allows the charger and smartphone to automatically align magnetically, enabling more efficient and stable charging than before.
Currently, many manufacturers, including Android smartphones, are moving towards Qi2 compatibility, and it is expected to become the future standard.
The Background of Qi2's Creation
With conventional Qi charging, you had to place your smartphone precisely in the center of the charger to achieve sufficient charging performance.
Even a slight misalignment could lead to:
- Reduced charging speed
- Increased heat generation
- Charging stopping midway
Such problems were not uncommon.
Qi2 was developed to solve these issues.
The Role of the Wireless Power Consortium (WPC)
The WPC is an organization of electronic device manufacturers worldwide responsible for developing and certifying the Qi standard.
With Qi2, the certification system has been further strengthened, allowing users to confidently choose certified products.
How does Qi2 work?
The biggest feature of Qi2 is **Magnetic Power Profile (MPP)**.
What is Magnetic Power Profile (MPP)?
MPP means that both the charger and the device have magnets.
They attract each other to the correct position and automatically fix to the optimal charging position.
As a result, it achieves:
- Reduced power loss
- Suppressed heat generation
- Stable high-speed charging
has been achieved.
How Magnetic Alignment Works
With conventional Qi, users had to manually adjust the position.
With Qi2, on the other hand, the magnets automatically center the device, allowing for optimal charging every time.
This significantly improves convenience, especially in situations where you charge many times a day, such as before bed or during desk work.
Differences in Charging Efficiency Compared to Conventional Qi
Less misalignment improves power transmission efficiency and reduces wasted power consumption and heat generation.
As a result, it also helps to reduce the burden on the battery.
Qi2 vs. Conventional Qi
When comparing Qi2 and conventional Qi, there are the following differences:
| Item | Qi | Qi2 |
|---|---|---|
| Alignment | Manual | Magnetic Adsorption |
| Charging Efficiency | Normal | High |
| Heat Generation | Slightly High | Low |
| Stability | Affected by misalignment | Very High |
| Convenience | Standard | Very High |
Charging Speed
With Qi2, power can be supplied in the optimal position, making the actual charging speed more stable.
Heat Generation Performance
Reduced power loss due to misalignment also suppresses heat generation.
Reduced heat generation also lowers the risk of battery degradation when used for long periods.
Energy Efficiency
Qi2 improves power transmission efficiency, allowing for more efficient energy supply even with the same charging time.
This also contributes to reducing environmental impact.
Compatibility
Qi2-compatible devices can be charged with Qi chargers, but Qi2-compatible accessories are required to utilize magnetic adsorption and Qi2's unique performance.
Benefits of Qi2-Compatible Products
Qi2-compatible accessories offer various advantages.
Smartphones
Magnetic adsorption allows for easy one-handed charging.
The stable charging position makes it comfortable to use even while on the go or at a desk.
Mobile Batteries
With a Qi2-compatible mobile battery, you can simply attach it to the back of your smartphone for cable-free charging.
This offers great convenience when you're out and about.
Wireless Chargers
With desktop chargers and stand-type chargers, you can continue charging without misalignment even while watching videos or in online meetings.
