Your retail window opens in fourteen weeks, the packaging artwork is nearly signed off, and the factory tells you the line is full until after the season. Capacity is usually treated as a detail of the purchase order. In practice it is the constraint that decides whether a launch happens on time, and it is booked long before the design is finished.
Why capacity is booked before design is finished
A charger line is planned as a block of hours, not as an infinite service. SMT capacity, assembly benches, aging racks and test stations are finite, and a factory allocates them weeks ahead across many customers. That is why the useful question is not “when can you make my charger” but “when must I commit so that a slot exists for me”. The answer depends on three variables: the platform you choose, whether tooling is required, and the season you are shipping into.
The factory calendar: when charger lines actually fill
Charger production is seasonal, but not in the way most buyers expect. Demand peaks twice: once in late spring and summer, when brands build stock for back-to-school and autumn retail resets, and once in early autumn, when distributors finalise Q4 and holiday inventory. Between those peaks there are windows that suit trial orders and range extensions. A programme that books in a quiet window can often start within days of the purchase order; the same programme in September may wait weeks for a bench slot even when the materials are ready.
What to confirm before you ask for a date
A factory cannot hold capacity for an undefined product. Before a realistic date can be given, three things need to be fixed: the platform or model you are re-badging, the wattage and port configuration you need, and the market you are shipping to, because the plug kit and the certification state follow from it. If any of those is still open, any date you receive is provisional and should be treated as such.
Deposits, tooling and the three booking milestones
Most factories work with three milestones rather than a single reservation. The spec freeze establishes what will be built; the order confirmation with deposit converts an enquiry into planned capacity; the tooling release starts the calendar that ends with the pilot run. Missing one milestone moves the slot, which is why the sequence matters more than the deposit amount.
| Milestone | What is fixed | What it unlocks |
|---|---|---|
| Specification freeze | Platform, wattage, ports, plug kit, branding position | A provisional date and a costed quotation |
| Order confirmation and deposit | Quantity, packaging route, certification status | A named slot in the production plan |
| Tooling release or sample approval | Enclosure, print plates, approved golden sample | Materials release and a firm production week |
Platform reuse: the fastest honest route to a slot
A tooled platform that is already in production removes the longest stage from the critical path. Re-badging an existing model with your logo, colour, labels and retail box does not restart the enclosure schedule, and re-specification within tested limits avoids a new engineering loop. The result is a shorter, more predictable route to capacity, which is why the first branded order is often a platform order rather than a new form.
How peak season changes the answer
In peak weeks, the practical lead time is set by the queue rather than by the production time. A programme that needs 200 pieces and a platform change may still find a bench, but a programme that needs new tooling plus certification plus packaging artwork will not compress into the same window. If your launch date is fixed, the honest options are to move earlier in the calendar, choose a platform that is already tooled, or split the launch so the platform SKUs ship first and the new form follows.
What to send in the first enquiry
- Device list and the wattage each one needs, with the largest device called out
- Target markets, which determine the plug kit and the compliance documents
- Whether you are re-badging, re-specifying or developing a new form
- Quantity for the trial order and the annual volume you expect
- Launch date and the date stock must leave the factory
- Packaging route: retail box, e-commerce mailer or bundle
With those six items, a factory can answer with a dated plan rather than a range. Send the device list and target markets to Wecent Group for a costed slot assessment; quotations are returned within 24 hours on business days.
Red flags in a promised date
Be cautious when a date is given without a platform, when the same date is offered for both a re-badged model and a new enclosure, or when the lead time is quoted in months without stating what triggers the clock. A credible answer references the milestone that starts the schedule and names the item that could move it. Ask what happens if the artwork is late, or if certification takes longer than planned, and see whether the answer is a new date or a shrug.
Slot-booking checklist
- Platform chosen and configuration fixed
- Target markets and plug kit confirmed
- Trial quantity agreed, with the annual projection stated
- Certification state understood before the date is promised
- Packaging artwork owner and deadline named
- Deposit and milestone dates written into the order
Frequently asked questions
Can I reserve capacity before paying for tooling?
A provisional slot can be discussed, but it is not firm until the order is confirmed. Tooling release is what converts a provisional date into planned production, because the enclosure schedule is the long pole for a new form.
How far in advance should a 200-piece trial order be booked?
For a platform SKU, two to four weeks is usually enough in a quiet window and considerably longer in peak season. For a new enclosure, the tooling and sample loop sets the schedule regardless of the order quantity.
What happens to my slot if certification takes longer than planned?
It moves, unless the programme is built on a platform whose certification is already established. This is the main commercial argument for choosing a certified platform for a first launch.
