Repair Preview
- Move the pack and charger to a dry, ventilated room-temperature location and let a hot or cold pack normalize before continuing.
- - Inspect the charger cord, case, cavity, and pack for cracks, liquid, scorching, swelling, unusual heat, or conductive debris - stop for any hazard.
- Prove the outlet with another appliance, plug in the designated charger, and seat the pack fully.
- Read charging, full, temperature-delay, and problem indications only by that exact charger manual.
- - Cross-check with one known-good compatible pack or designated charger - retire the failed external item or use authorized service without opening either hou
