What should we check before re-ordering a charger model a year later?

Confirm the specification, components and test reports are unchanged, check labels against current rules, compare the new golden sample with the old one, and review a year of returns before you sign the re-order.

The question

Our 100W charger sold well last year and we want to re-order. A year has passed since the first order. What should we check before placing it?

Main answer · Wecent Editorial Team

Short answer: Ask Wecent to confirm in writing whether anything changed: components, PCB revision, housing material, firmware or factory. Check that test reports and certificates are still valid for the current standard editions, that labels and packaging meet any new rules, and request a pre-production sample to compare with your retained golden sample. Review your returns from the first batch and fix any recurring issue in the new order.

Ask about changes

Component changes, including second-source parts.
PCB or firmware revisions.
Housing material or colourant supplier.
Production location.

Changes aren’t always bad, but they can affect test reports and performance. Ask for a written statement of changes since your last order.

Check documents

Are test reports still valid, and do they cover current standard editions?
Do changed components require updated reports?
Is your DoC current, with correct standards and company details?

Check rules that changed

In the EU, examples in recent years include GPSR (applying from 13 December 2024) with traceability and contact information, the common charger rules and pictograms for in-scope devices, and battery rules for power banks. Similar updates happen elsewhere. Update artwork before production.

Compare samples

Keep a golden sample from the first order. Ask for a pre-production sample and compare appearance, colour, labels, weight and performance on key devices. Differences should be explained before mass production.

Use returns data

Review the return reasons from the first batch. If loose plug heads, scratches, or a port issue appeared repeatedly, ask Wecent for a corrective action and add a check in the AQL clause.

Commercial points

Updated price and validity; confirm what changed in costs.
Lead time: Wecent’s product pages state 7–15 days mass production after sample confirmation; confirm for your quantity.
Packaging stock: is leftover branded packaging from last time usable?

Marketplace listings

If the model or packaging changed, update photos, specifications and compliance documents on each marketplace listing. Mismatches between listing and product are a common reason for complaints and listing suspensions.

Inspection

Book a pre-shipment inspection for the re-order, even if the first order went well. Use the same AQL clause and checklist so results are comparable across orders.

Same model, new risks

Treat a re-order after a long gap as a partial new launch. A short checklist now avoids surprises at customs, on marketplaces or in returns.

Where this answer says confirm with Wecent, the detail is not published on the product page and has to come from the datasheet or the factory. General facts come from the standards bodies, regulators or device makers named in the text.

Three more perspectives

Wecent Editorial Team · Purchasing perspective

Ask for a written “no change” confirmation, or a change list, as part of the purchase order. It sets expectations for both sides.

Wecent Editorial Team · Compliance/QC perspective

Keep the first batch’s golden sample sealed and labelled. Without it, comparisons a year later rely on memory and photos.

Wecent Editorial Team · After-sales perspective

Share your return reasons and photos with Wecent before re-ordering, not after. Fixes are easier before production starts.
