Wireless charging has transformed how we power our devices — and the Qi standard has been leading this transformation for over a decade. Developed by the Wireless Power Consortium (WPC), Qi ensures universal safety, compatibility, and performance across brands.
From Qi1 to Qi2.2, every version has introduced faster charging speeds, stronger magnet alignment, and improved energy efficiency. For consumers, this means convenience and reliability; for distributors and OEM/ODM partners, it represents a crucial competitive edge.
As a professional wireless charger and power bank manufacturer, D-WIRELESS has evolved alongside the Qi standard — from early 5W Qi1 pads to today’s 25W Qi2.2 power banks and chargers.
1. What Is Qi and Why It Matters
The term “Qi” (pronounced chee) comes from Chinese, meaning “energy flow.” It’s the global standard for inductive and magnetic wireless charging, managed by the WPC.
Qi allows energy transfer between two coils through electromagnetic induction. The latest versions also include magnetic alignment for stability and faster charging.
Today, Qi is supported by nearly all major smartphone brands, and it continues to evolve toward higher wattages, lower heat, and smarter charging algorithms.
2. Quick Comparison: Qi1 vs Qi2.0 vs Qi2.1 vs Qi2.2
| Version | Release Year | Max Output Power | Magnetic Alignment | Efficiency | Key Improvements | Ideal Products |
| Qi1 | ~2010 | 5W | ❌ None | 50–60% | Basic inductive charging | Simple charging pads |
| Qi2.0 | 2023 | 15W | ✅ Magnetic Power Profile (MPP) | 70–75% | Magnetic alignment, faster charging | MagSafe-type chargers, magnetic power banks |
| Qi2.1 | 2024 | 15W | ✅ Improved MPP | 75–80% | Smarter communication, cooler operation | Foldable 3-in-1 chargers, car mounts |
| Qi2.2 | 2025 | 25W | ✅ MPP 2.0 (Stronger Magnets) | 80–85% | Faster 25W wireless charging, AI-based safety | Qi2.2 power banks, desktop chargers, travel chargers |
3. Qi1 — The Beginning of Wireless Charging (Up to 5W)
Introduced around 2010, Qi1 was the foundation of modern wireless charging. It worked on inductive coupling and required precise alignment between the charger and device.
- Power Output: 5W
- Efficiency: Around 60%
- Main Limitation: Alignment sensitivity and slow charging
At D-WIRELESS, our first Qi1 chargers focused on safety, stability, and heat management, helping us develop strong R&D capabilities for future wireless power designs.
4. Qi2.0 — The Magnetic Revolution (Up to 15W)
Qi2.0, released in 2023, introduced Magnetic Power Profile (MPP) — a breakthrough inspired by Apple’s MagSafe system.
This addition allowed phones to magnetically snap into perfect charging alignment, reducing power loss and ensuring stable energy transfer.
Key Features
- Output: Up to 15W
- Efficiency: 70–75%
- Compatibility: iPhone 12+ and Qi2-certified Android models
- Magnetic Alignment: Yes (strong built-in magnets)
Factory Insight
D-WIRELESS upgraded its assembly lines to produce Qi2.0 wireless chargers and magnetic power banks, combining precision magnet placement, optimized PCBA, and durable materials.
Products like our 15W magnetic pads and 3-in-1 foldable chargers became popular choices among distributors and private-label clients.
5. Qi2.1 — Smarter, Cooler, and More Compatible
By 2024, WPC enhanced the standard further with Qi2.1, optimizing temperature control, safety, and multi-device support.
Core Improvements
- Dynamic power communication
- Better thermal control
- Enhanced cross-brand compatibility
- Upgraded FOD (foreign object detection)
D-WIRELESS integrated these improvements into its Qi2.1 modules, ensuring our chargers and power banks operated safely under continuous use. Each product underwent CE, RoHS, FCC, and Qi certification testing before shipment.
6. Qi2.2 — The Next Leap: 25W Wireless Charging and Qi2.2 Power Bank
Released in 2025, Qi2.2 represents a major performance leap — enabling 25W wireless charging with Magnetic Power Profile 2.0 (MPP 2.0).
Technical Highlights
- Output Power: 25W (66% increase over Qi2.0)
- Efficiency: 80–85%
- Alignment: Stronger magnetic hold with MPP 2.0
- Safety: Intelligent temperature and current monitoring
- Compatibility: Backward-compatible with Qi2.0 and Qi2.1
The Qi2.2 power bank quickly became the flagship application of this standard. Offering both fast wireless charging and portable convenience, it’s now the top choice for distributors and tech brands.
