How to Write a USB-C Charger Sourcing Brief

A USB C charger sourcing brief should define the target devices, charging scenarios, destination markets, first-order quantities and repeat-order expectations as separate requirements. It should also tell suppliers which configuration to quote, what evidence to provide and which assumptions need your approval.

For brand buyers and importers, this creates a usable basis for comparison. Without it, two quotations for a “65W charger” may cover different port combinations, cables, market versions and customization work.

At KYT, a useful starting point for a sourcing discussion is the job the charger must perform. The brief below turns that job into a product shortlist, a document request and a sample approval plan.

Start with devices and simultaneous charging scenarios

Define which devices must charge together before choosing a wattage or port layout. Separate the power a device needs when used alone from the capability you require when several ports are occupied.

List exact device models, their official charging requirements and the cables intended for the bundle. “Samsung compatible,” “for laptops” and “fast charging” leave too much open: the supplier needs to know which devices, which charging modes and what the customer should experience.

For each scenario, describe whether the device is charging while idle or operating under a defined workload. Record the preferred port, any charging-speed claim you intend to advertise and whether adding another device may reduce the power available to the first.

USB Power Delivery manages power between connected products; a charger's headline rating does not mean every device will draw that amount. Build the requirement around the capabilities of the complete charging setup, using the USB-IF explanation of USB Power Delivery as technical background

Make the power-sharing requirement explicit

Hypothetical example: A buyer wants one port to make 45W available to a laptop while a second port offers 20W to a phone. These are illustrative procurement targets, not KYT model specifications or promises of actual device power draw.

The supplier must confirm whether its proposed model supports that combination with the required output profiles. If it cannot, ask for a clearly identified alternative: a different allocation, a higher total rating or a revised device-priority rule.

Also request behavior when a cable is inserted or removed. Your sample plan should check whether existing connections renegotiate or briefly interrupt charging and whether that behavior suits the intended use.

Include cable length, connector type, required power and current capability, and whether electronic marking is needed for the proposed operation. A certified cable does not increase the capability of the charger or device; the USB-IF cable guidance makes this distinction explicit.

Define market versions and compliance responsibilities

Write a separate market requirement for each destination. A plug choice describes the physical connection; the compliance file must address the product, its intended market and the businesses responsible for placing it there.

For an EU and Australia launch, identify the actual countries or jurisdictions, sales channels, plug versions, label languages and importer arrangements. Record the intended launch date so the compliance review can consider the requirements applicable when the product enters the market.

European Union

Ask for the applicable legislation and standards, the EU Declaration of Conformity and supporting technical evidence for the proposed model and variant. Assign responsibility for reviewing the documentation, product identification, instructions and final artwork.

CE marking is the manufacturer's declaration that applicable requirements have been met. A business having products made and selling them under its own brand may itself be considered the manufacturer, so private-label buyers should establish their role early. The European Union's CE marking guidance explains these responsibilities and the conformity-assessment process.

Australia

Name the local business responsible for compliance and ask it to confirm the applicable electrical-safety pathway. Where EESS applies, check the Responsible Supplier registration, equipment risk classification, required evidence, any required equipment registration and RCM marking arrangements against the official EESS compliance steps.

Address applicable ACMA obligations as well. Its supplier compliance process covers checking the rules, demonstrating compliance, keeping records, registration and labeling.

For both markets, ask the supplier to distinguish documents already available for the exact variant from work still required. Give every outstanding item an owner and completion stage. A certificate image in a presentation is insufficient to establish that your selected version is ready for sale.

Separate the first order from repeat demand

State the launch purchase and the replenishment plan independently. A first order is a purchasing requirement; an annual forecast is planning information unless you expressly commit to buying it.

Break the first order down by model, plug, color, packaging language and included accessories. Ask whether MOQ applies to the total order, each electrical variant, each color or each printed packaging version. This makes a supplier's minimum quantity meaningful for your actual SKU mix.

Hypothetical example: An importer plans a first order of 1,200 units, split between 800 EU-version units and 400 AU-version units. The buyer also forecasts 600 units per quarter, subject to sell-through. These are planning assumptions, not KYT MOQ conditions, accepted quantities or sales forecasts.

The supplier should quote the opening order against that split and state the conditions for future replenishment. A combined order total does not establish that every packaging or plug variant meets its own purchasing minimum.

Ask for dates with defined starting points

Separate sample preparation, customization approval, compliance work, production and transport. Ask which event starts each quoted period: approved artwork, specification freeze, deposit receipt, material availability or another agreed milestone.

Specify both the required dispatch date and the required warehouse-arrival date. Ask for the shipping term, named place, included freight costs, quotation currency, payment terms and price-validity period. Compare offers on the same commercial basis.

For repeat orders, record the expected order interval, typical quantity per version and acceptable changes. Ask how the supplier will notify you about component substitutions, packaging revisions or discontinued parts. Also agree warranty scope, evidence needed for a claim and responsibility for return or replacement costs.

Set customization boundaries before requesting a price

Separate mandatory features from preferences and optional upgrades. Suppliers should quote the same required configuration first, then explain the cost and development effect of alternatives.

Logo printing and packaging changes belong in a different request line from a new housing, revised port layout or modified electrical design. This helps the supplier identify work that fits an existing platform and work that needs engineering validation or tooling.

Use the KYT custom phone charger service page as a starting point for discussing branding and product changes. Ask for project-specific confirmation of the available options, quantities and timing before treating any website statement as a purchase commitment.

Describe housing dimensions, plug mechanism, color reference, finish, logo position, label content and packaging format. Include cable requirements and any retail barcode or language versions. Mark drawings and artwork with revision numbers so an old file cannot silently become the basis for a quotation.

If a display or retractable cable is optional, request it as a separate configuration. Ask what additional functionality, structural validation and sample checks it would require, and whether it changes the intended launch schedule.

Explain your priorities when requirements conflict. A smaller enclosure, more ports and a lower target cost may need different compromises; the brief should show which requirement can move. If GaN is a preference rather than a mandatory specification, invite a technically justified proposal and compare the complete product against the same size, thermal, functional and cost criteria.

Ask suppliers to separate recurring unit costs from one-time charges for tooling, engineering, testing or artwork. For new tooling, agree ownership, maintenance responsibility and the conditions for later design changes.

Build a shortlist with separate evidence for each model

Treat a product family as a place to identify candidates. Each shortlisted model needs its own configuration record and supporting evidence before you can compare its suitability.

The KYT 65W USB-C wall charger range is a relevant starting point for a 65W sourcing discussion. Request the exact model, suffix, plug version and current datasheet revision for each proposal.

If your candidate list includes KYT830 and KYT834A-65W references, keep them on separate lines. Their suitability remains subject to current model documentation and sample validation. Do not copy a power-allocation table, protocol claim or certification list from one candidate to the other.

For each candidate, request:

• Electrical specification: AC input rating, port labels, single-port output profiles, supported protocols and simultaneous-use allocation for the combinations you require.

• Mechanical configuration: dimensions, plug version, enclosure revision and the cable or accessories included in the quoted package.

• Compliance evidence: model identifiers covered by the documents, applicable market versions and any unresolved work.

• Commercial offer: quantity basis, customization scope, excluded charges, sample conditions and production assumptions.

• Validation plan: relevant device combinations, test conditions, acceptance criteria and the version that will be supplied for testing.

Check that the model name on the quotation matches the datasheet, sample label and compliance documents. Where a document covers a family, request confirmation that your exact variant is included and that any differences are addressed.

Keep buyer requirements, supplier claims and verified results in separate columns in your working shortlist. A brochure statement belongs under supplier claims until the relevant evidence supports it. When documents conflict, ask for a reconciled, dated specification rather than choosing the more attractive number.

Use this one-page USB C charger sourcing brief template

Keep the main brief short enough for a supplier to review in one pass. Attach detailed device lists, drawings and test requirements separately, with filenames and revision dates referenced in the brief.

Fill in the buyer column below and ask each supplier to complete the response column against the same revision.

Use short entries in this template and place detailed evidence in attachments. Require suppliers to write “unconfirmed” against unresolved items rather than leaving cells blank. Keep the first-order quantity separate from the repeat-order forecast, even when both appear in the same request for quotation.

Add this response instruction beneath the table:

Identify the proposed model and revision. Mark each requirement as met, partly met or unconfirmed, with evidence. List deviations and assumptions separately. Quote optional alternatives separately from the required configuration.

Keep a revision log when requirements change. Send the same update to every shortlisted supplier and ask each to identify its effect on configuration, documents, price and timing. This preserves a fair comparison when one supplier responds before a specification change and another responds afterward.

Review supplier responses before approving samples

Compare configuration and evidence before comparing the headline price. A lower quotation is useful only when you understand what it includes, which requirements it meets and which risks remain unresolved.

Use the KYT company profile for supplier background, then request the project-specific information needed for your shortlist. Company-level material cannot replace evidence for the exact product you intend to buy.

Use this review table to decide what needs clarification before committing to samples or production.

Apply the same questions to every supplier. A specific, documented limitation is easier to evaluate than an unsupported promise. Record each unresolved point with an owner and due date before moving the candidate forward.

Turn the brief into a sample approval plan

Agree what the samples must demonstrate: charging with the listed devices, the required port combinations, cable insertion and removal behavior, physical fit, labeling and packaging. For thermal evaluation, specify the environment, load, measurement method and acceptance criteria rather than asking whether the charger “runs cool.”

Request the proposed functional, Hi-Pot and burn-in or aging controls, including their purpose and applicable conditions. Distinguish routine production checks from compliance testing and agree which evidence you will receive. Do not assume that a generic test name defines a sufficient acceptance plan.

Before production approval, identify the approved sample and freeze the agreed specification, relevant bill-of-materials revision, firmware where applicable, artwork and inspection criteria. Require notification and review of changes that could affect performance, compliance or interchangeability. Apply the same version controls to replenishment orders so that the approved product remains identifiable beyond the launch batch.

Conclusion

A useful USB C charger sourcing brief gives suppliers a clear problem to solve and gives buyers a consistent way to judge the answer. Define the devices and simultaneous charging scenarios, separate market versions, and distinguish the opening purchase from future demand.

Then ask each supplier to connect its proposed model to a dated specification, applicable compliance evidence, a transparent commercial offer and an agreed sample plan. For KYT830, KYT834A-65W or any other candidate, assess the exact version individually and resolve conflicting information before making product claims.

Start with the one-page template, attach your device list and market requirements, and mark optional features separately. That gives the next discussion a practical focus: which configuration fits, what remains unconfirmed and what must happen before production approval.

Send your target devices, market and feature requirements to KYT.

FAQ

What should a USB C charger sourcing brief include?

Include the devices, charging scenarios, markets, first-order quantities and repeat-order expectations. Add the required ports, protocols, cables, customization and compliance responsibilities. Ask suppliers to identify their proposed model, provide supporting documents and list assumptions separately.

Can I use one power-allocation table for all 65W chargers?

No. Request the allocation table for each exact model and relevant revision. Check the port combinations your customers will use, because a shared headline wattage does not establish identical simultaneous outputs. Confirm the proposed behavior during sample testing.

What should I request for EU and Australian market versions?

Request separate variant and compliance records for each market. For the EU, identify the applicable requirements and supporting conformity documentation. For Australia, have the responsible local business confirm the applicable safety, registration, labeling and ACMA obligations described above.

How should I distinguish the first order from repeat orders?

State the first purchase by SKU and label future quantities as forecasts unless they are committed orders. Ask for MOQ and pricing conditions for both the launch mix and expected replenishment mix. Specify how changes to components, packaging and documentation will be managed.

Do I need a finalized charger model before contacting KYT?

No. Start with exact target devices, use scenarios, markets and mandatory features. Ask for candidate models with separate specifications and clearly stated limitations. Keep the shortlist provisional until the relevant documents and samples support your requirements.
