The custom GaN charger project is the bridge between a brand’s idea and a branded product, and the bridge is built on the specification: the electrical requirements, the mechanical targets, the compliance scope and the brand layer, decided in order and frozen in writing. This page is the custom GaN workflow for OEM buyers — the spec-first method, the platform decision, the project gates and the rework loops to avoid.
The Spec-First Method
The custom GaN project starts with the specification, not the packaging: define the electrical requirements from the device list — the wattage, the ports, the protocols and the PDO table — then the mechanical targets — the size, the weight, the plug and the finish — then the compliance scope — the markets and the certificates — and finally the brand layer — the logo, the colors and the packaging. The order matters because each layer depends on the one before it: the branding is the final layer on top of a defined product, and a project that starts with the branding inherits the electrical decisions from the factory’s catalog. The spec-first method is the difference between a custom product and a relabeled one.
The Platform Decision
The custom GaN project’s fastest path is the platform: a certified platform with the brand layer applied, versus a from-scratch design with new engineering and new tooling. The platform decision should be made from the spec’s fit — whether the electrical and mechanical requirements fit within a proven platform — because a perfect match on a platform ships fast and cheap, while a mismatch forces a new project wearing a platform label. The buyer should review the platform’s evidence — the PDO table, the thermal data, the certificate file and the change log — before the branding work, because the platform’s quality is the brand’s floor. Wecent’s OEM/ODM service runs the platform review as the first project step, which is where the custom decision should start.
The Custom Spec Sheet
| Section | Must define | Why it matters |
|---|---|---|
| Electrical | Wattage, PDO table, ports, protocols | Sets the device coverage |
| Thermal | Sustained load, surface temp limit | Sets the real-world rating |
| Mechanical | Size, weight, plug, material | Sets the tooling and the feel |
| Compliance | Markets, certificates, labels | Sets the lead time and the cost |
| Branding | Logo, colors, packaging | Sets the MOQ and the NRE |
| Volume and timeline | Forecast, milestones | Sets the project plan |
The spec sheet is the RFQ document and the project’s contract; the factory’s response to the sheet is the first test of its engineering.
The Project Gates
The custom project runs the standard gates: spec freeze, electrical sample, brand sample, compliance run, pilot batch. The electrical sample is tested against the spec — the charging performance with the target devices, the thermal behavior and the protocol verification — and the brand sample fixes the logo, the colors and the finish on the actual housing. Each gate has a written approval, and the approvals are the project’s record. The gate that custom GaN projects most often skip is the electrical sample review with the actual devices, and the skip is how the “it charges everything” claim becomes the “it charges nothing” return.
The Compliance Scope for the Custom Model
The custom model’s compliance scope is the per-market certificate set naming the custom configuration: the wattage, the ports, the plug and the housing. The scope should be frozen with the spec, because a market added after the freeze adds a certificate and a timeline, and a housing change after the certification can trigger a re-assessment. The buyer should also decide the certificate ownership early — whether the factory holds the approvals or the certificates are issued or transferred to the brand’s name — because the ownership affects the timeline and the marketplace access.
The Rework Loops to Avoid
The custom GaN project’s rework loops repeat across brands. The spec loop: the buyer changes the wattage or the ports after the freeze, and the electrical sample resets. The brand loop: the logo is approved from a render and fails on the actual material, caught at the physical sample. The compliance loop: the market list grows after the certification plan, and the certificates add weeks. The tooling loop: the housing is designed without the DFM review, and the tool needs rework. Each loop is prevented by the same habits: freeze the spec with the change-request discipline, approve physical brand samples, lock the market list and run the DFM review before the tooling.
The Brand Layer in Detail
The brand layer is the final layer of the custom project, and its details decide the product’s feel: the logo placement and the print method on the housing, the color and the finish, the cable and the accessories, the packaging structure and the insert. Each detail should be approved on a physical sample, because the render cannot show how the logo behaves on the material, how the color shifts under light or how the packaging feels in the hand. The brand layer also carries the regulatory marks and the language set, and the sample should verify the marks’ placement and legibility. The custom brand that approves the physical samples ships the product it designed; the one that approves the render ships the surprise.
The Cost Structure of a Custom Project
The custom project’s quote should break the cost into the layers: the engineering (the electrical and mechanical adaptation), the tooling (the molds and the fixtures), the certification (the per-market fees and the lab time), the packaging (the artwork and the materials) and the NRE (the custom electronics or the firmware work). The cost structure is the negotiation map — the platform reuse compresses the engineering and the certification, the branding depth sets the packaging and the NRE, and the tooling is the line that should never be cheapened. The buyer who sees the cost structure knows where the savings are real and where the savings are the next project’s risk.
The Custom Project Timeline
The custom GaN project’s timeline is the gate schedule: the spec freeze, the electrical sample, the brand sample, the compliance run and the pilot, with the dates and the owners named. The timeline’s variables are the platform reuse, the certification scope and the brand depth — a platform-based project with the markets frozen ships on a short schedule, while a from-scratch design with new markets runs on a long one. The buyer should treat the timeline as a contract with the approval deadlines on their side named, because the project’s speed is the intersection of the factory’s schedule and the buyer’s decisions, and the schedule that names both is the schedule that ships.
Bottom Line
The custom GaN charger is a spec-first project: define the electrical, mechanical, compliance and brand layers in order, choose the platform by the spec’s fit, run the gates with the records and avoid the rework loops with the freeze discipline. The brand that runs the spec-first method gets a custom product; the one that starts with the logo gets a relabeled catalog item. The spec-first method is also the relationship’s foundation: the spec sheet, the gate records and the approvals become the shared reference for the factory and the brand, and the project that runs on the documents is the project that survives the changes, the staff moves and the reorders — the discipline is what turns a one-off custom order into a repeatable program capability.
For a custom GaN project review with the platform options and the spec template, contact Wecent through the contact page; the OEM/ODM service covers the project from the spec freeze to the pilot, and the review starts with the spec sheet rather than the sales call, which is the first evidence of how the project will run.
Frequently Asked Questions
What is the minimum quantity for a custom GaN charger?
The MOQ depends on the platform reuse and the branding depth; a platform-based custom project carries a lower MOQ than a new design, and the quote separates the product and the branding minimums.
How long does a custom GaN project take?
For a platform-based project, the timeline is driven by the samples and the certification; for a from-scratch design, add the engineering and the tooling. The gate schedule in the quote is the answer.
Can we customize the PDO table?
Within the platform’s capability, yes; the protocol table is part of the electrical spec, and the platform review decides which profiles the custom model can advertise.
Who owns the certificate for a custom model?
The factory holds the approvals by default; many programs arrange the certificates in the brand’s name, which affects the timeline and the fee structure and should be decided at the spec freeze.
Can we use our own housing design?
Yes, if the design passes the DFM review and the compliance scope; a new housing means new tooling, and the platform review is the gate that decides whether the custom geometry is worth the cost. The housing decision should be made with the tooling quote and the timeline impact in hand, because the custom geometry’s cost is not the mold alone but the certification and the lead time that travel with it, and the geometry that looks right in the render is only right when the DFM review says it can be built.
