This page is for B2B buyers who have already decided to add Qi2 to their line and now need three answers: how to prove a charger is genuinely Qi2 certified, which devices it will actually charge well, and how to choose the right model without paying for capability nobody will use. It is written from a factory-buying perspective — the perspective behind Wecent's wireless charger collection: what documents to request, what test data separates a real Qi2 product from a magnetic Qi charger with a new label, and how to match form factors to the customers you sell to. If your question is about launch timing, SKU rollout or retail pricing, the new-product series on the Wecent blog covers that; this page deliberately stays inside certification, compatibility and selection.
What Qi2 Certification Actually Covers
Qi2 is the Wireless Power Consortium's (WPC) second-generation specification, and its defining addition is the Magnetic Power Profile (MPP). A ring of magnets in the charger pulls a matching ring in the phone into a narrow coil-to-coil alignment window, which improves efficiency, reduces heat and makes charging repeatable across devices and brands. The magnetic architecture that MagSafe popularized was licensed into an open standard, which is why the same charger can serve iPhones and MPP-equipped Android devices.
For a buyer, two consequences matter more than the marketing story. First, Qi2 is a specification, not an adjective: a certified product has passed testing at a WPC-qualified laboratory and is listed in the public Qi product database. Second, certification is model-specific. A certificate number belongs to one model with one coil, one magnet assembly and one housing; changing the coil size, moving the magnet ring or swapping the housing shell can require retesting. When a supplier says "our platform is Qi2 certified," ask for the certificate of the exact model you are quoting, not of a similar product.
There is also a power nuance worth pinning down before you build a spec sheet. The certified baseline for MPP is 15W. Several platforms advertise 25W or higher through extended or vendor-specific power profiles, and those higher ratings are not automatically covered by the standard 15W MPP certificate. Ask your supplier to state in writing which certificate covers the wattage you plan to print on the retail box.
Certification document checklist
| Document | What to check before the PO |
|---|---|
| WPC Qi certificate | Model name and number match your SKU exactly; wattage listed matches your spec |
| Test report from a WPC-qualified lab | Covers MPP alignment, sustained power, thermal and foreign object detection |
| Qi logo license | Licensee is the factory or your brand; covers the markets you ship to |
| Public Qi database listing | Search the model number to confirm it is current and searchable |
| Production QC records | Coil, magnet and thermal test data for the batches you are buying |
Request all five before the order, then re-request the QC records at each new production batch. The certificate is design-level proof that a model can meet the spec; it says nothing about whether this week's production run was assembled with the same coil tolerance and magnet strength. That is why the last row of the checklist matters as much as the first.
Compatibility: Which Devices Actually Benefit
The magnet ring only helps devices that carry a matching ring. iPhones from the 12 generation onward include the magnetic array, so they get MPP-aligned charging from a Qi2 charger. A growing number of Android models ship with the ring or are announced as "Qi2 Ready"; when the hardware is present, the phone receives the same aligned charging. Devices without magnets still charge on a Qi2 charger through the standard Qi profile, but with manual positioning and the same efficiency profile as today's Qi chargers.
That single fact should shape every compatibility claim you make. Qi2 does not break older devices, but the effortless "drop and charge" experience is reserved for phones with the magnet ring. If your catalog copy promises aligned charging, the promise only holds for that subset.
Cases change the picture as well. A magnetic case preserves alignment because the phone's ring is strong enough to pull through it. A thick non-magnetic case — generally anything over 2–3 mm, and any case with metal — can push the coil out of the alignment window or trigger foreign object detection. Brands that sell cases alongside chargers should test the combination before launch; this is a common source of "it doesn't charge my phone" returns.
Device compatibility matrix
| Device group | Magnetic alignment | Expected charging result | Notes |
|---|---|---|---|
| iPhone 12 and later | Yes | 15W aligned charging | Works with MagSafe-compatible cases |
| Android with MPP / Qi2 Ready | Yes (if ring present) | 15W aligned where supported | Confirm per phone model |
| Android without magnets | No | Standard Qi speeds | Manual positioning required |
| Older Qi phones and earbuds | No | Standard Qi speeds | No benefit from the magnet |
| Watch and earbud accessories | n/a | Via station coils only | Only on multi-device stations |
Choosing the Right Qi2 Form Factor for Your Line
Four form factors dominate B2B demand: pads, stands, 3-in-1 stations and magnetic power banks. The specification does not decide between them; the customer's environment does. A pad suits a single-phone nightstand, a stand suits a desk where the phone is used for video calls, a 3-in-1 suits a household with a watch and earbuds, and a power bank suits travel — see current models such as the C11 15W magnetic pad, the X40 mini 3-in-1 stand, the Y302 Qi2 3-in-1 station and the L8 Qi2 magnetic power bank. Start with the device mix and the location, then pick the form factor — not the other way around.
A second consideration is SKU discipline. Certification is priced per model, so each extra model adds its own certificate, logo administration and test report. Buyers with tight margins are usually better served by one or two well-chosen certified models with brand customization than by a wide range of unverified claims. This is the one place where the budget question belongs in selection: fewer, certified models beat many, uncertified ones.
Form-factor decision table
| Form factor | Primary use | Devices covered | What to verify |
|---|---|---|---|
| Qi2 pad | Bedside or desk, single device | Phone only | Magnet ring position, surface temperature |
| Qi2 stand | Office desk, video calls | Phone, optional earbuds | Viewing angle, heat path, cable management |
| 3-in-1 station | Premium desk or nightstand | Phone, watch, earbuds | Watch coil certification, power sharing between coils |
| Magnetic power bank | Travel | Phone, passthrough charging | Battery cell certification, magnet retention during movement |
Five questions that narrow the choice in one pass:
- What devices will the end customer place on it?
- Where will it live — desk, bedside, bag or countertop?
- Is it a single-device or multi-device purchase?
- Who buys it: consumers, corporate gifts or a retail chain?
- How many SKUs can the certification budget support this year?
What to Verify With the Factory Before You Order
The certificate answers "can this model meet Qi2?" Production data answers "does this batch meet Qi2?" Four checks matter in every order:
Alignment consistency. The magnet ring's position tolerance across batches determines whether 15W is actually sustained. Ask for the production limit and the measured distribution, not just a single sample photo.
Sustained power. Many chargers reach 15W briefly and then settle lower. A 30-minute sustained test at 25°C ambient is more informative than the peak number on the box.
Surface temperature. Temperature rise affects both safety and certification compliance. Ask for the soak-test temperature at the end of a full charge cycle, not the temperature after two minutes.
Foreign object detection. A coin or key between charger and phone should be detected and power reduced. Ask for the FOD test method and result; this is a safety feature, not a spec-sheet extra.
Field note from Wecent's QC lab
A representative 15W Qi2 pad from a recent Wecent production batch: after a 30-minute soak at 25°C ambient, sustained output held between 14.5W and 14.8W with fluctuation within ±0.3W after warm-up; alignment offset at the production limit was within 0.8 mm; surface temperature rose 12–15°C above ambient at the end of the soak; a foreign object detection test with a 10 mm metal disc produced no measurable heating beyond a 5°C rise. These values vary by model and are supplied with each SKU's latest test report. [Replace this paragraph with the actual QC report of the model you quote before publishing.]
Budget and Lead-Time Drivers
Four factors move the quote: certification status, tooling, power platform and packaging. An already-certified reference design — like the models in the product collection — is the fastest path to market: you pay for brand customization, logo application and packaging, but not for a new certificate. A new model with new certification adds WPC program fees, lab time and retest risk; certification timelines are typically measured in weeks to months depending on the lab queue, so ask for a dated project plan rather than a promise. A 25W extended-power platform costs more in engineering and validation than a 15W MPP baseline. MOQ is set per model and depends on magnet and coil assembly setup plus packaging configuration, so request the current price sheet for the specific SKU you want rather than applying a generic minimum.
Bottom Line
Choose certified models with per-model certificates and batch QC data, match the form factor to the customer's device mix, and keep SKU count aligned with the certification budget. The document set — certificate, test report, logo license, database listing and batch records — is the fastest way to separate a real Qi2 line from a relabeled Qi charger.

Frequently Asked Questions
Can we print the Qi2 logo before the certificate is issued?
No. Logo usage requires a valid license from the WPC program, and printing it early risks a compliance issue and a costly reprint. Confirm the license covers the markets you ship to before artwork is finalized.
Do Qi2 power banks need certification beyond Qi?
Yes. A Qi2 magnetic power bank still requires battery cell and transport certifications — typically UN38.3 and IEC 62133 for the cell, plus applicable air-shipping rules — which are separate from the Qi certificate and are checked independently by freight forwarders and customs.
Can an existing Qi pad be upgraded to Qi2 with a firmware change?
No. Qi2 needs a magnet ring, a repositioned coil, revised foreign object detection and updated thermal design, and the new configuration must pass certification. In practice this is a new product project, not a software update.
Are Qi2 and MagSafe the same thing?
Not exactly. Qi2 uses the same magnetic alignment principle that MagSafe popularized, but it is an open standard managed by the WPC, while MagSafe remains Apple's proprietary ecosystem. A Qi2 charger will charge MagSafe-equipped iPhones at aligned speed without an Apple license; a separate Apple certification program only matters if you want to market your accessory through Apple's own channel and carry its branding.
Does the Qi certificate cover the phone as well as the charger?
No. The Qi certificate you receive from your supplier covers the power transmitter — the charger itself. The phone's receiving side is certified by its own manufacturer. What you need on your side is the charger certificate plus a compatibility verification against the exact phone models you target, which is exactly what the compatibility matrix above is for.
