Power Bank Supplier Evaluation Scorecard
Compare suppliers with the same evidence-based framework across manufacturing, engineering, cell/PACK, quality, compliance, samples, commercial execution and change control.
Rule: no evidence, no full points. A critical project risk should be closed even when the total score is high.
Supplier Scorecard · 8 Decision Areas
Rate each area from 0–5, then apply the section weight. Keep the same method across competing suppliers and close any critical risk before approval.
01 · Manufacturing Reality — 10%
Factory role · lines/equipment · production control · traceability · CAPA.
02 · Product Engineering — 15%
Cell/PACK · PCB · PD/PPS · cable/thermal · DFM/NPI.
03 · Cell / PACK Control — 20%
Cell model · lot traceability · PACK architecture · substitution control.
04 · Quality System — 15%
IQC/IPQC/final control · functional/aging tests · defect handling · CAPA.
Manufacturing & Quality Evidence — verify real production control, traceability and corrective action.
Engineering & Product Control — check cell/PACK, charging, structure, thermal and validation capability.
05 · Compliance Evidence — 10%
Exact-SKU report matching · battery/transport evidence · market/labels. Certification →
06 · Sample Discipline — 10%
Sample ID/revision · test/deviation records · golden-sample control.
07 · Commercial Execution — 10%
Quotation scope · MOQ/lead time · project ownership · response. MOQ & Lead Time →
08 · Change Control & After-Sales — 10%
BOM/component notice · buyer approval · defect response · corrective action.
Critical-Failure Rule
Section score = (average rating ÷ 5) × section weight. No evidence, no full points. Close uncontrolled substitution, weak traceability, missing change control or mismatched compliance/transport evidence before supplier approval.
Evidence to Verify
High scores should point to evidence another reviewer can inspect: documents, drawings, samples, test results, traceability records or factory observations.

Approval Signals & Red Flags
Good Signs
✓ Exact cell and configuration identified.
✓ Engineering uses measurable data.
✓ Samples carry IDs and revisions.
✓ Documents match the proposed SKU.
✓ Deviations and changes are controlled.
Red Flags
× “A-grade cell” with no controlled model.
× “Supports PD” with no profile/test evidence.
× One document set claimed for unrelated SKUs.
× No sample/BOM/firmware revision state.
× Silent component substitution is treated as normal.
