Power Bank Retention Samples: How to Investigate Complaints Against the Shipped Batch

Worker recording a power bank inspection beside finished units and cartons

Retain traceable finished units from the approved build and shipped lots under a written sampling and storage plan. Record the exact SKU, lot, revision, seal, selection method, location and custody. When a complaint arrives, compare the returned unit, retention sample and release record using the same approved method. Set sample quantities and duration from market obligations, risk, volume and the quality agreement; no universal count fits every project.
