PRODUCT DESIGN & PLATFORM DECISIONS
Power Bank Product Design & Platform Guides
Start with the user and SKU role. Then choose the right platform, capacity, power and CMF before engineering or tooling begins.
Choose the Platform by Use Case
Start with how the customer carries and charges.
slim · mini
built-in cable
phone alignment
direct-plug · AC
retractable
tablet · laptop
Four Product Decisions
entry · core · premium · travel
mini · cable · magnetic · plug
5K · 10K · 20K · 20W–45W
color · finish · geometry · packaging
Capacity & Power
5,000mAh: compact carry. 10,000mAh: everyday core. 20,000mAh: longer runtime and higher-power use.
Choose 20W–45W around the real device mix, size, heat and cable capability.
Product Design Workflow
User & channel → platform → capacity/power → CMF → ODM or private mold → engineering handoff.

Match the Use Case to a Platform
Choose the platform first, then refine around the user, charging scenario and channel.
CMF or Private Mold?
Use color, material, finish, geometry, cable treatment and packaging as one product-family language.
If housing, mechanism, display or interface positions must change, move from a mature ODM platform to controlled upgrade or private mold →
Move to a Buildable Brief
Define user, market, channel, SKU role, platform, capacity, power, interfaces, dimensions, CMF, packaging, volume and timing.
Useful Resources & Evidence
Power Bank Product Design FAQ
How should a buyer choose 5,000mAh, 10,000mAh or 20,000mAh?
Choose by user and runtime need: 5K for compact carry, 10K for everyday use and 20K for longer runtime or higher-power devices. Size and weight rise with capacity. Capacity reference →
Built-in cable, retractable cable or direct-plug?
Built-in cable favors simple all-in-one use, retractable cable improves storage with more mechanism, and direct-plug prioritizes compact top-up without a loose cable. Match the form factor to how the customer carries and charges.
Does magnetic attachment automatically mean Qi2?
No. Magnetic attachment, wireless power and Qi2 certification are separate decisions. Define the required charging standard and certification scope for the exact SKU. WPC reference →
When is a mature ODM platform enough?
Use a mature platform when CMF, branding, packaging or limited changes create enough differentiation. Use a controlled upgrade or private mold when structure, mechanisms, electronics or interface positions must materially change. Private Mold & ODM →
