Technical Basics, Safety & Care

Convert mAh to real device charges with simple Wh math, account for efficiency losses, and verify labeling to meet airline rules and avoid checkpoint hassles.

Cut through airline power bank rules with protocol-accurate steps: convert mAh to Wh, measure real output, verify UN38.3 and labeling, and match carrier-specific limits and in-flight bans. Use the compliance workflow to choose banks that avoid confiscation and power devices reliably.

Translate UN38.3, UL2056, and IEC 62133 into practical checks - accurate Wh labeling, validated protection circuits, safe thermal practices, and proper storage - to ensure airline compliance and reduce failure risk. Use the preflight checklist to avoid confiscations and extend power bank lifespan.

Decode the real differences between USB PD and Qualcomm QC to avoid mismatched fast charging, thermal shutdowns, and airport confiscations. Use the included compliance checklist - Wh labeling, UN38.3 documentation, protocol testing, and cable requirements - to choose a safe, travel‑ready power bank.
