Qi vs Qi2 Wireless Charging: What Importers and Brands Should Check
Qi is the Wireless Power Consortium’s wireless-charging standard; Qi2 builds on it with a Magnetic Power Profile designed for consistent alignment and interoperability. For sourcing, the label alone is not enough: verify the exact product in the WPC database, confirm the supported device and power conditions, and test the complete charger–device–case–adapter setup.
Qi and Qi2 in Practical Buyer Terms
Qi defines a common approach for compatible wireless power transmitters and receivers. The Wireless Power Consortium introduced Qi2 in 2023. Its Magnetic Power Profile uses magnetic alignment to position compatible devices and chargers; WPC describes the original Qi2 profile at up to 15 W and has since introduced a higher-power Qi2 25W specification.
Those are standards-level descriptions, not proof that a specific supplier product is certified, supports every profile or delivers a headline power level to every device. Product verification must be exact.
Qi vs Qi2 Sourcing Comparison
| Question | Qi sourcing check | Qi2 sourcing check |
|---|---|---|
| Alignment | Check the product’s coil position, stand geometry and intended device placement | Confirm Magnetic Power Profile implementation and intended compatible cases/devices |
| Certification | Search the exact product in the WPC database if certification is required | Search the exact Qi2 product/profile in the WPC database; do not infer from magnetic appearance |
| Power | Confirm the supported profile and device-dependent output conditions | Confirm the exact Qi2 version/profile, input requirement and device support |
| Accessories | Verify cable and adapter requirements | Verify cable, adapter and any magnetic case/accessory requirements |
| Sample testing | Test the buyer’s device/case matrix | Test alignment, retention and charging with the buyer’s device/case matrix |
Magnetic Does Not Automatically Mean Qi2
A product can use magnets for alignment without being a Qi2-certified product. Conversely, a buyer should not rely on the appearance of a magnetic ring or a broad compatibility sentence. Ask for the exact model identification and look it up in the official certified-product database when certification is part of the purchase requirement.
The current W93 foldable magnetic wireless charger can be used as a model reference during an RFQ, but its current specification and any certification requirement must be confirmed for the quotation.
Power Claims Need Conditions
Wireless charging output is affected by the product profile, input source, device support, alignment, temperature management and concurrent charging conditions. Ask whether a stated wattage applies to one charging position, a combined product configuration or a maximum supported profile. Confirm the recommended adapter and cable.
For a multi-device station, list the phone, watch and earbud devices expected to charge together. Request the relevant input requirement and evaluate the complete setup during sample review.
How to Verify a Certification Claim
- Obtain the exact commercial product/model name and any certification identifier from the supplier.
- Search the Wireless Power Consortium certified-product database.
- Compare the database entry with the exact product, brand, model and profile being quoted.
- Confirm that customization or configuration changes do not create an unverified assumption about the listing.
- Keep the search result or relevant record with the project approval documents.
Buyer Questions for a Qi or Qi2 RFQ
- What exact wireless charging standard/profile does this model support?
- Is the exact product listed in the WPC certified-product database, and under what name or identifier?
- Which phones, watches, earbuds and case conditions should be tested?
- What input adapter and cable are required for the stated output?
- Does the wattage refer to one position or a combined maximum?
- What changes when multiple charging positions are used together?
- Which statements and logos may appear on packaging for the confirmed product?

Frequently Asked Questions
Is Qi2 simply a higher-wattage version of Qi?
No. Qi2 introduced a Magnetic Power Profile and alignment-focused interoperability. Power capability still depends on the specific Qi2 version/profile, product and device.
Does every magnetic wireless charger use Qi2?
No. Magnetic appearance or alignment alone is not proof of Qi2 certification.
How can a buyer check certification?
Search the exact product in the Wireless Power Consortium’s official certified-product database and compare its details with the quoted model.
Will a certified charger deliver the same output to every phone?
No. The device, profile, input adapter, alignment, case and operating conditions can affect the supported charging behavior.
