8. Troubleshooting

Q1: Why does my power bank provide less power than expected?

During use, some energy is lost due to voltage conversion (3.7V > 5V) and internal heat—typically 30-45%. For example, a 20,000mAh power bank usually delivers 11,000-13,000mAh, which is standard across the industry.

Q2: Can I take this power bank on a plane?

Yes. This power bank has passed the UN38.3 test, the safety standard required by ICAO and IATA for lithium batteries in air transport.

Q3: What are the instructions before use for better battery accuracy?

For better battery level accuracy, we suggest fully discharging to 0% and then charging to 100% without stopping.
