Power Bank Reliability Test Plan & Validation Checklist
Validate the released product state with four practical checks. Identify the exact SKU and revision, define the stress condition, keep measured evidence and close every failure before release.

Reliability Validation — 4 Practical Checks
Use project-specific limits. For every check record the exact sample state, condition, measured result, acceptance rule and disposition.
Best for: proving the exact released electrical state.
Model / SKU / sample ID: ___
BOM / PCBA / firmware: ___
Cell / PACK lot: ___
Capacity / Wh: ___
Charge-discharge profile / cycles: ___
Post-test behavior: ___
Decision: Pass / Retest / Hold
Best for: validating the operating envelope and protection behavior.
Input / output profile: ___
SOC / ambient / duration: ___
Hotspot / temperature result: ___
Environmental condition: ___
Protection / recovery result: ___
Decision: Pass / Retest / Hold
Use controlled laboratory procedures for abnormal-condition testing.
Best for: finding wear, drop, connector and moving-part risks.
Drop / structural condition: ___
USB-C / connector state: ___
Built-in cable / flex cycles: ___
Retractable / stand / plug / button: ___
Wear / retention / post-cycle function: ___
Decision: Pass / Rework / Retest
Best for: deciding whether reliability evidence is ready for NPI.
Failure / issue ID: ___
Containment / root cause: ___
Corrective action: ___
Affected revision: ___
Re-test evidence: ___
Release: Approved / Conditional / Hold
Rule: reliability results belong to the exact tested revision. If the cell, firmware, PCBA, cable, housing or mechanism changes, review whether the affected checks must be repeated.
Release Decision & Next Step
Defined tests meet the project acceptance criteria and evidence is linked to the tested revision.
Limited open items have a named owner, due date and closure evidence.
A corrective action or relevant product change requires the affected condition to be verified again.
Do not move to release until the failure or revision mismatch is closed.
