You bring the concept. Our R&D team designs the circuit, tooling, firmware, and exterior from scratch. Tooling ownership, design rights and any exclusivity are defined in the manufacturing agreement.
- ✓ Custom PCBA and circuit design
- ✓ Proprietary mold and tooling
- ✓ Custom firmware development
- ✓ MOQ typically from 2,000 units for new tooling or original structural development
For YULIDA quotations, distinguish branding on an existing model, configuration changes and new product development. Use the written scope to agree on engineering work, tooling, sample validation, design rights and ownership before choosing a service tier.
Three Ways to Build Your Brand
Whether you need logo printing on stock models or a fully customized product from scratch, YULIDA has the right service tier for your project stage and budget.
Production ranges are planning estimates for the agreed configuration after the required approvals and material readiness. They do not establish the total time from inquiry to delivery. Confirm tooling, sample validation, project-specific testing, production and transport dates separately in the quotation.

Your Power Bank Manufacturing Process
From first inquiry to mass production delivery, we keep the process transparent and you informed at every stage.
Inquiry & Requirements
Share your product needs, target market, quantity, and budget. Our sales engineer responds within 24 hours with a preliminary proposal.
Sample & Specification
We send physical samples for evaluation. For ODM projects, our R&D team creates a technical specification document with 3D renderings and circuit diagrams.
Quote & Agreement
Final pricing based on confirmed specs, quantity, and customization level. We sign an NDA and manufacturing agreement covering IP, quality, and delivery.
Tooling & Pre-Production
For ODM: custom mold creation and PCBA prototyping. For OEM: artwork files finalized and packaging materials produced. A pre-production sample is sent for sign-off.
Mass Production & QC
Full production follows the approved specification and quality plan. Finished-unit inspection, battery-cell-lot aging and batch records are applied according to the selected model and purchase order.
Shipping & After-Sales
Confirm packaging, labeling, transport method, the agreed Incoterm and route-specific documents before dispatch. Warranty scope, claim handling and responsibility for related costs are recorded in the order agreement.
The stages above show an illustrative project sequence. Actual timing depends on the product, engineering work, material availability, sample approvals, inspection and shipment route. Confirm each milestone and distinguish factory dispatch from arrival at the destination.
