Step 1: Business Demand Communication

You send your purchase needs to our overseas sales team.

You tell us clear information: product type, target power wattage, order quantity, brand printing demands and special function requests.

Our sales staff sort all your information and send formal feedback within 24 working hours.

Step 2: Custom Solution & Price Confirmation

If you choose OEM service: We match our existing mature product models to your demands. We make official quotation based on your total order volume.

If you choose ODM service: Our R&D engineers check your custom ideas. We draw initial design drafts and calculate full production cost. We send complete design plan and price list for your review.

You put forward modification suggestions or sign to confirm the plan and price.

Step 3: Custom Sample Production

We start sample making after you confirm the plan and finish sample fee payment.

OEM samples use our standard product structure with your printed logo and custom packing box.

We finish all samples within 7 to 15 working days. We send sample photos, official test reports or physical samples for your quality check.

Step 4: Sample Modify & Final Standard Confirmation

You check sample power performance, surface look, logo printing quality and packaging details.
