2. Multi-Layer Circuit Protection: Quality power banks incorporate NTC temperature controllers, over-voltage protection, short-circuit cutoffs, and fire-retardant polycarbonate outer shells.
3. True Capacity vs Rated Capacity: Remember that a 20,000mAh 3.7V power bank converts to around 13,000mAh of actual usable output capacity due to voltage step-up conversion.
