Three levels of customisation are usually described with the same word, and the cost difference between them is a fixed-charge difference rather than a material one. A branded platform build and a new enclosure can carry the same electronics and differ by more than the price of the product.
Custom charger cost: the three levels
Branding on a certified platform, re-specification inside the tested envelope, and a new enclosure or electrical design.
The levels are not a ladder of quality. Each answers a different commercial question, and each adds a different fixed charge: artwork and plates at the first, engineering and documentation at the second, tooling and a test programme at the third.
The cost comparison only becomes meaningful when the fixed charges are placed beside the unit price, because at a small opening quantity the fixed line dominates and at a large one it nearly disappears.
Level 1: branding on a certified platform
Artwork, colour, finish, cable and packaging, with the electrical design untouched.
The fixed cost is limited to artwork and print plates per version, and the certification work is a label and file update where the platform already covers the markets. The opening quantity is set by the packaging version and the test time rather than by tooling, which is why this level can open at a few hundred pieces per model. Its limitation is differentiation: the form is shared with other customers of the platform.
Level 2: re-specification inside the tested envelope
Ports, plug kits, cable ratings and small mechanical changes.
The added cost moves from artwork to engineering: documentation, sample verification and possibly a review by the test house where a characterised parameter is touched. There may be small tooling for a changed clip or a different plug housing. The benefit is that the configuration differs while the platform, the certification basis and the production process stay the same.
Level 3: a new enclosure or electrical design
Tooling, trial loops and a test programme, with the opening quantity following the moulding economics.
The fixed charges here are an order of magnitude larger than at level one: the mould and its trials, the fixtures and gauges that make the assembly repeatable, and the certification work on the finished configuration. The unit price may be lower or higher depending on the volume, and the first order has to carry the fixed total. This level is justified when the form is the reason customers buy, when the volume can amortise the tooling, or when the specification needs something no platform provides.
| Level | Fixed charges added | Certification work | Opening quantity | Differentiation |
|---|---|---|---|---|
| Branding | Artwork and print plates | Label and file update | Set by packaging version | Branding only |
| Re-specification | Engineering, documentation, samples | Review or update | Set by the change | Ports, plugs, cable |
| New design | Mould, trials, fixtures, test programme | New submission | Set by the moulding batch | Form and architecture |
What each level adds to the fixed charges
Four groups, and where each level stops.
Mould and die: only at level three. Fixtures and gauges: at level three, and small items at level two where the assembly changes. Trial loops: level three. Packaging plates: at every level, once per artwork version. Reading the levels through those four groups explains why level one can start small and why level three cannot, and it also shows where a quotation is incomplete.
Where the money goes over the first year
The comparison changes with the quantity, not with the level. The quantity decides.
At a few hundred units the fixed charges dominate every level, and the cheapest route is the one with the fewest of them. At tens of thousands the fixed charges are absorbed and the material and process lines decide, which is where a level three design can become competitive per unit while remaining more expensive overall. The useful exercise is a first-year total at the quantity the forecast supports, not a unit price comparison.
Choosing the level
Three questions settle it.
Does the form decide the purchase, or the specification, or the price? Can the forecast amortise the tooling within a reasonable period? And does the brand need a configuration no platform provides? Where the first answer is the specification, level two is usually the efficient route; where it is the form and the volume is there, level three is justified; where it is the price, level one is the honest answer.
FAQ
Is level three always more expensive?
It is more expensive in fixed charges, and not always in unit price. At high volume a new design can carry a competitive unit cost, while the programme total remains higher because of tooling, fixtures and certification. Compare the programme total rather than the unit price, because the fixed charges are where the third level differs and where the comparison is decided.
Can we start at level one and move up later?
Yes, and it is a common route: prove the channel with a branded platform build, then re-specify or tool once the reorder rate justifies it. The later step pays the fixed charges with data behind the decision. The later step pays the fixed charges with sales data behind the decision, which is why the route is common and usually cheaper overall.
Does level two require new certification?
It requires an assessment of what changed. Where the changes stay inside the characterised envelope, the file is updated; where a parameter moves, a review or a partial submission follows. Ask which parameters changed and compare them with the characterised envelope, because a change inside it is a file update while one outside it is a test. and the result is recorded against the file revision.
What is the most common cost surprise at level three?
The fixtures and the trial loops. Both are necessary for a repeatable assembly and both are often absent from an initial tooling quotation, which makes the first invoice larger than expected. Ask for the fixtures and the trial loops to be quoted separately from the tooling, because they appear in the first invoice rather than in the unit price. and ask for them in the first quotation.
