The sample was approved in March and the shipment left in June. Nothing had gone wrong in production; the label text changed after the print plates were cut, the reprint moved behind another customer’s run, and the programme absorbed eleven weeks in a queue. The decisions that keep an adapter programme on schedule are made before the tooling, and the most expensive one to make late is the smallest: the words on the label.
This guide is part of our OEM & ODM Charger Programmes. Read the full topic guide for the decisions that come before and after this step.
Custom power adapter programme: the five decisions that carry the schedule
Five decisions determine whether the programme ships on the planned date.
The output and connector specification, the platform or new-design route, the certification scope and label content, the packaging proof, and the pilot. Each has an entry condition, and each one, if left open, converts a schedule into a negotiation.
The reason the label content ranks as high as the electrical specification is that it sits on the critical path immediately before printing, where the remaining float is smallest. A label change after the plates are cut is a reprint; a reprint is a queue; and the queue is what the customer experiences as a slip. Freezing the label text early is one of the cheapest decisions available in the programme.
Decision 1: output, connector and polarity
State all three in writing and confirm all three on a physical sample with a meter.
Voltage and current set compatibility, the connector sets the fit, and the polarity decides whether the equipment works or is damaged. Connector and polarity errors dominate returns in this category because they are agreed once and rarely re-checked. Ask how the factory inspects polarity in production and whether the result is recorded per unit.
Decision 2: platform or new design
Where a platform covers the output and the connector, the programme avoids tooling and a test submission.
A branded adapter can open at 200 pieces per model on an existing platform with the label, colour and packaging applied. A new enclosure or a new output configuration carries tooling and sample loops, which sets a higher minimum and a longer calendar. Ask the quotation to state which route it represents and to separate tooling from the unit price.
Decision 3: certification scope and label content
Freeze the label text before the print plates are produced.
The label carries the ratings, the model designation, the manufacturer identification and the market marks, and it has to match the certified product. Adapters are often assessed as part of the equipment they power, which means the adapter documentation must align with the end product’s technical file. Confirm which reports exist, which markets they name, and what the importer details must state for each destination.
Decision 4: the packaging proof
Approve an assembled box, not a flat artwork.
The proof brings the board grade, the insert, the print, the language versions and the accessories together, and it is the artefact that shows how they interact. Confirm the carton dimensions at the same time, because they decide the pallet pattern and the units per container, and that figure belongs in the landed-cost calculation rather than in a separate conversation.
Decision 5: the pilot
The pilot validates the process, and its report is what turns an engineering success into a manufacturing plan.
It should run on the production line with production fixtures and the approved sample, and the report should state the quantity, the yield, the defects found by category and the corrective actions taken. Only after the pilot should the production schedule be committed, because the process is what has to hold at rate – not the sample.
| Decision | Entry condition | What it protects |
|---|---|---|
| Output, connector, polarity | Specification agreed | Compatibility and returns |
| Platform or new design | Market list fixed | Tooling, MOQ and schedule |
| Certification and label | Markets and importer details confirmed | Print plates and compliance |
| Packaging proof | Accessories decided | Freight and packing |
| Pilot | Golden sample approved | Production at rate |
Scheduling the programme backwards
Work backwards from the shipment date and name the milestone that starts each stage.
Shipment date, production week, packing and outgoing inspection, pilot run, sample approval, and where they apply tooling and certification. Assign an owner to each stage and put a buffer in front of the shipment date. A schedule without a buffer assumes every loop passes first time and every artwork revision is approved without comment, which is not how tooling or printing behave.
What to verify before the order
Confirm the certification reports, the production test scope and the change-notification process.
Wecent Group prepares certification groundwork for CE, FCC, RoHS, PSE and KC and confirms the current status per model. Ask how the production test covers output, polarity and protection functions, and ask which components are treated as safety-critical and who approves an alternate. Those answers determine whether the shipped product continues to match the approved sample.
FAQ
“The label can be finalised while the cartons are being printed.”
The label sits immediately before printing in the sequence, where the float is smallest. A change after the plates are cut becomes a reprint and a queue, which is the most common cause of a late shipment in this category. Freeze the label before the plates are cut, because a change afterwards becomes a reprint and a queue rather than an edit.
“We can approve the packaging from the artwork file.”
An artwork file does not show the insert fit, the print colour on the board or the interaction with the accessories. Approve an assembled proof, and confirm the carton dimensions in the same review. Approve an assembled proof and confirm the carton dimensions in the same review, because the artwork file does not show the insert fit or the print colour on the board.
“A pilot is unnecessary for a platform product.”
On a platform product the pilot can be short, but it still confirms that the packing line and the label allocation match the approved sample. It is the cheapest test of the process available. Run it short but run it, because it confirms that the packing line and the label allocation match the approved sample. and name the person who signs it off.
