Wireless Charger PCBA for Cup Warmer and Desktop Charging Products
A wireless charger pcba is the core electronics platform that lets a desktop 2-in-1 accessory manage both cup warming and phone charging in one compact body. For buyers, the main problem it solves is space and convenience: one unit can keep coffee or tea warm on a desk while also providing a charging surface for a smartphone, reducing cable clutter and the need for separate tabletop devices.
Product Overview
Based on the visible board structure, this assembly combines a rounded PCB, a central spiral heating coil, a USB-C power input, and control components arranged around the edges. The overall layout fits the role of a mug warmer pcba or heating coaster pcba used inside a consumer desktop accessory. The printed markings visible on the unit include “Desktop 2-in-1 Solution” and “Cup Warmer & Phone Charging,” which clearly indicate the intended end use.
The electronics module shown appears suitable for OEM or ODM integration where a compact heating and charging subassembly is needed. It may also be used as a replacement internal board for repair or spare-parts sourcing. Because only the image is available, exact electrical ratings, charging protocol, and temperature performance should be confirmed before purchase.
Visible Structure and Functional Layout
PCB and coil arrangement
The board uses a blue solder-mask PCB with a large circular coil area in the center. A tightly wound spiral element is visible, along with a dark central support area and insulated lead connections. Around the lower and right edges, small surface-mount components, a red box-style capacitor, and a metal USB-C connector can be seen.
This layout suggests a compact power-transfer or heating control module where the coil and control electronics are integrated into one assembly. Whether the coil is used strictly for heating, wireless power transfer, or a combined function cannot be confirmed from the image alone, so it is best described as a coil-based heating/charging board.
Model and board identification
Visible markings include “EJ2066 V1.1” and “149501A-V74-210311.” These identifiers are useful for sourcing, revision matching, and PCB assembly documentation. For B2B buyers, keeping the same board revision is important when compatibility with enclosure geometry, connector positions, or firmware behavior matters.
Materials and Finish Options
The visible housing appears to be a white plastic enclosure with a glossy or matte surface finish. The internal board is a rigid FR-4-style PCB with blue solder mask and standard silkscreen markings. The coil appears to be insulated wire or flat copper winding wrapped with white insulating material. White lead wires and a taped section near the coil connection are also visible.
In manufacturing, finish options for this product family may include different enclosure colors, texture levels, PCB surface finish choices, connector positions, and coil insulation materials. Final options depend on the target power level, thermal design, and product housing.
Manufacturing Process and Assembly
This type of assembly typically involves PCB fabrication, SMT population, coil winding or coil module integration, connector soldering, and final electrical assembly. The board shown likely passes through reflow soldering for surface-mount parts, followed by manual or semi-automatic installation of the coil and lead wires. A complete unit would then be integrated into the plastic shell and checked for fit, polarity, and basic function.
hcdpcba supports SMT贴片, PCB打样, 元器件代采, 组装, 测试, and OEM/ODM service. For customers building a wireless charger pcba product, this kind of one-stop support is useful when the project requires board sourcing, assembly coordination, and process control in one workflow.
Application Scenarios
This board category is suitable for office desks, home workstations, dorm rooms, bedside tables, reception counters, and small retail or hospitality environments. A heating coaster pcba can help maintain beverage temperature during long work sessions, while the charging function supports everyday phone use at the same spot.
Typical buyer use cases include consumer electronics development, product refresh projects, spare-part replacement, and small-batch custom appliance production. The 55℃ constant temperature concept and 55 degree thermostatic cup heating coaster pcba module are common search terms in this segment, but exact temperature control capability must be verified by test data, not assumed from appearance alone.
Quality Control and Buyer Decision Factors
When choosing a board like this, buyers usually evaluate several factors: connector type, board revision, coil size, thermal control method, cable routing, component sourcing, and assembly repeatability. For a mug warmer pcba, the most important practical checks are stable heating behavior, reliable power input, safe insulation, and consistent board-to-housing fit.
Quality control for this product family normally includes visual inspection, solder joint review, continuity testing, functional power-up tests, and thermal verification. If the product is intended for mass production, DFMA review is also valuable because coil placement, component spacing, and enclosure geometry can strongly affect assembly efficiency.
Customization Guidance
Customization may cover PCB shape, connector orientation, coil layout, enclosure dimensions, surface graphics, and assembly method. If you need a wireless charger pcba for a new product, it is useful to provide target application, power input requirements, expected heating behavior, and mechanical constraints early in the development stage.
For replacement or compatibility projects, share the visible board markings, photos of both sides, connector locations, and enclosure dimensions. That information helps reduce trial-and-error and improves the chance of matching an existing design.
