Choose the Right Development Route

new private mold power bank architecture

Existing Platform

Change the logo, color, packaging or standard configuration.

Internal Modification

Keep the housing while adjusting the PCB, battery, cable, screen or ports.

New Private Mold

Use when the shape, structure or user experience must be different.

Validation Before Tooling

ZEROSET power bank development team and factory validationFactory + Engineering Review

We check the battery, PCB, structure, thermal design and assembly before tooling.

Feasibility Check

Structure — size and assembly
Electronics — PCB, ports and power
Battery — cell space and capacity
DFM — heat and production feasibility

Custom Power Bank Development FAQ

1. What can I send to start?
A photo, link, sketch, rendering, 3D file or physical sample.
2. What is the MOQ?
Existing platform: 1,000 pcs. Internal modification: 2,000 pcs. New private mold: 3,000 pcs. Standard colors normally start from 500 pcs per color.
3. How long does development take?
Mature-platform samples are typically 7–10 days. Modified and private-mold projects are scheduled after feasibility review.
4. How long does mass production take?
Mature-platform production is normally around 30 days after approval. Tooling projects require additional prototype and pilot validation.
5. When is a new mold necessary?
When the outer shape, internal structure, mechanism or interface layout must materially change.
6. What compliance support is available?
Common support includes CE, FCC, RoHS, UN38.3, MSDS and IEC 62133. Other market requirements are reviewed by project.
