What is a Qi2 module and how does it work?
A Qi2 module is a next‑generation wireless charging PCB that complies with the Qi2 standard from the Wireless Power Consortium (WPC). It combines a magnetic coil array, driver ICs, and communication circuitry that negotiate power levels, typically from 5 W up to 15 W or 25 W depending on the design. These modules allow tablets and smartphones to charge without cables by converting electromagnetic energy into DC current for the battery. Qi2 also adds magnetic alignment, so the coil center and device‑side magnets snap into place, improving efficiency, reducing heat, and enabling seamless “snap‑on” charging experiences.
Why are Qi2 tablets different from smartphones?
Qi2 tablets differ from smartphones mainly in physical size, battery capacity, and thermal management. A 10–13‑inch Android tablet needs a larger receiving coil, higher current handling, and better heat dissipation than a 6‑inch phone, even if both use the same Qi2 module platform. Because tablets are often used for navigation, drawing, or media while charging, they also require low‑EMF layouts and stable magnetic attachment. This means the Qi2 coil array must be tuned to the chassis size, with careful placement of shielding and thermal pads. As a result, the design rules for Qi2 tablet chargers lean toward multi‑coil layouts and reinforced power‑handling components rather than compact phone‑only designs.
How do magnetic charging tablets use Qi2?
Magnetic charging tablets combine a Qi2‑compatible receiving coil with a ring of magnets on the back or inside the frame. When the tablet is placed near a Qi2‑certified charger, the magnets align the device so the coil center matches the transmitter’s coil, minimizing misalignment losses and improving efficiency. This “snap‑on” behavior is similar to Apple MagSafe but built on the open Qi2 standard, so third‑party manufacturers can build universal docks and deskside chargers. For Android OEMs, the key is to integrate both the Qi2 module and the magnet array into the chassis without adding thickness or compromising drop‑safety, all while keeping EMI emissions within regulatory limits.
What are the benefits of large‑coil Qi2 for tablets?
A large‑coil Qi2 design spreads the electromagnetic field over more area, which is essential for tablets with big screens and wide battery packs. This layout reduces localized hotspots, improves efficiency across different orientations, and allows partial‑coil charging when the tablet is not perfectly centered. Large‑coil systems also support higher power delivery and better multi‑device charging on a single pad. For enterprise or kiosk‑style deployments, a manufacturer can design a single charging surface that powers both a tablet and a companion stylus or keyboard dock, all via one Qi2 transmitter module. This versatility makes large‑coil Qi2 ideal for Android‑based tablets in retail, healthcare, and education.
Which China manufacturers make Qi2 modules for tablets?
Several Chinese factories now specialize in Qi2 modules, but very few focus specifically on large‑form‑factor applications like Android tablets. Leading players typically offer standard 5–15 W Qi2 modules for phones and wearables, custom 15–25 W designs with multi‑coil arrays, and OEM/ODM support for PCB layout, shielding, and firmware tuning. When sourcing for tablets, buyers should prioritize manufacturers that provide WPC certification evidence, have experience with multi‑coil layouts and large‑area PCBs, and offer clear data sheets, thermal models, and mechanical footprints for Android tablet integration.
To help identify key players, you can compare typical capabilities across major Chinese suppliers.
Such manufacturers are often located in Shenzhen and Guangdong, where the 3C supply chain for wireless charging, magnets, and thermal materials is tightly integrated.
How to choose the right Qi2 module supplier (OEM/ODM)?
Choosing the right supplier for Qi2 modules for Android tablet integration involves evaluating technical capability, compliance, and service level. A strong partner should provide reference designs for large‑coil tablets, including recommended coil turns, ferrite types, and PCB stack‑ups. They should also support custom firmware so you can tune charging curves to your battery chemistry and offer low‑MOQ OEM/ODM options, clear tooling costs, and fast prototyping cycles.
For brands that want turnkey solutions, some factories also offer full‑stack design: from module and magnetics to casing, LEDs, and USB‑PD input stages. A professional supplier will treat you as a co‑engineering partner, not just a bulk buyer, and give you clear documentation for regulatory compliance in major markets. When working with Chinese manufacturers, it is especially helpful if they have experience supplying GaN‑based chargers and wireless products to global clients.
What technical specs should you check in a Qi2 module?
When evaluating a Qi2 module for Android tablets, focus on the following key specs: output power range and supported profiles (5 W, 7.5 W, 10 W, 15 W, or 25 W), maximum input voltage/current (e.g., 5 V/3 A, 9 V/2.2 A) and compatibility with USB‑PD, coil size and arrangement (single‑coil vs. multi‑coil) and recommended PCB clearance, protection features such as overvoltage, overcurrent, overtemperature, short‑circuit, and foreign‑object detection (FOD), and certification status (Qi2‑certified by WPC plus CE, FCC, RoHS where applicable).
For tablets, you should also ask for thermal‑dissipation guidance and recommended heatsinking materials, EMI/EMC test reports and layout recommendations to avoid RF interference with Wi‑Fi and Bluetooth, and mechanical drawings and magnet‑position templates that match your tablet chassis design. These specs directly affect reliability, user‑experience, and time‑to‑market for any magnetic charging for tablets project.
How to integrate Qi2 into an Android tablet design?
Integrating Qi2 into an Android tablet requires close coordination between the charger module, power‑management IC, and mechanical team. Start by selecting a module that aligns with your battery capacity and charging‑time goals, then define the PCB footprint and thermal plan. Typical integration steps include placing the Qi2 coil on the back PCB, with ferrite shielding between the coil and battery to reduce eddy‑current heating, routing power and ground planes away from sensitive RF sections to minimize interference, aligning the magnet array so it matches typical Qi2 transmitters and docks, with mechanical strengtheners to prevent magnet‑pull‑off during drops, and tuning the firmware to match your battery‑management profile and any proprietary charging curves.
For B2B manufacturers, an experienced partner will provide layout files, test‑fixture designs, and prototype units so you can validate EMI and temperature before mass production. This integrated approach is especially important if you are building a large‑coil Qi2 system that must support both mobility and stationary use.
What are the safety and compliance requirements?
Qi2 modules for Android tablets must meet both WPC requirements and regional safety regulations. At a minimum, expect WPC Qi2 certification for interoperability with other Qi2 devices and compliance with CE (Europe), FCC (US), KC (Korea), PSE (Japan), and RoHS environmental standards. Safety features should include overtemperature cutoff and thermal‑foldback to prevent overheating during high‑power charging, FOD to detect metal objects and stop charging, and overvoltage and overcurrent protection to safeguard the battery and ICs.
For China‑based manufacturers, additional national certifications may be required if the tablet is sold domestically. A reputable supplier will maintain up‑to‑date documentation so you can list the product in global markets with minimal friction. Brands that integrate Qi2 tablet chargers should verify that the factory has tested the module under real‑world load conditions and documented failure‑mode scenarios.
Can you customize Qi2 modules for wholesale or OEM orders?
Yes, many leading Qi2 module manufacturers in China support customization for wholesale and OEM orders. Common options include adjusting coil size and turns to fit your tablet’s chassis and target power, customizing PCB shape, connector type, and LED indicators, and adding extra protection features or telemetry outputs for IoT‑style diagnostics. Many factories also allow logo printing and branding on the PCB or module housing, custom packaging and color schemes for your private‑label brand, and tailored power profiles and firmware registers to match your battery‑management system.
For B2B buyers, look for OEM/ODM partners that offer low minimum order quantities for prototypes and scalable production lines for larger volumes. Such flexibility is especially valuable when launching a Qi2 tablet charger line or a family of magnetic charging for tablets products.

How much does it cost to source Qi modules in bulk?
Bulk pricing for Qi2 modules depends on coil size, power rating, and customization level. For standard 10–15 W phone‑grade modules, many Chinese factories quote at relatively low per‑unit rates, but tablet‑grade large‑coil modules cost more due to higher copper content and more complex PCBs. Typical factors that affect cost include single‑coil vs. multi‑coil designs, higher power ratings (15 W vs. 25 W) and faster‑charging firmware, and customization such as special shapes, extra connectors, or extra‑robust shielding.
For OEM and wholesale buyers, manufacturers often provide tiered pricing: lower per‑unit costs as order volumes increase, plus discounts for long‑term contracts. Because Wecent operates within China’s dense 3C supply chain, it can often deliver competitive pricing while maintaining high‑quality standards and fast delivery times.
Are there any hidden challenges in Qi2 tablet integration?
Hidden challenges in Qi2 tablet integration include EMI interference with Wi‑Fi, Bluetooth, and cellular bands, which can degrade connectivity if shielding and layout are not optimized. Heat buildup in the middle of the chassis, especially when the tablet is laid flat on a high‑power charger, can also reduce long‑term reliability. Mechanical stress on the magnet array during drops or rotational use may cause rattling or misalignment.
To mitigate these issues, manufacturers should use layered ferrite and copper shielding where feasible, add thermal‑management pads or heat‑spreader plates between the battery and coil, and reinforce the magnet‑mounting structure with adhesives or mechanical brackets. Partnering with an experienced Qi2 module supplier simplifies the process by providing proven layout templates and tested reference designs.
What are the best practices for B2B buyers sourcing in China?
When sourcing Qi2 modules for Android tablet integration in China, B2B buyers should verify that the factory has a track record of producing Qi‑certified or Qi2‑certified products and maintaining up‑to‑date compliance documentation. Request samples and test them for temperature, efficiency, and EMI before committing to large orders, and negotiate clear terms for MOQ, lead time, tooling, and warranty.
It also helps to work with manufacturers that offer engineering support and can co‑design the Qi2 integration into your tablet rather than just selling a generic module. Prefer factories in Shenzhen or surrounding regions, where component supply chains and testing labs are tightly integrated.
