Airline Travel: This 30000mAh (111Wh) power bank meets the requirements for most airlines (under 160Wh limit). However, always check with your specific airline before flying, as policies may vary. Some airlines may require approval or have different limits.
Charging Time: Due to the large 30000mAh capacity, this power bank takes approximately 8-10 hours to fully recharge. Use a 2A or higher charger for fastest recharge time.
Actual Capacity: Due to voltage conversion and energy loss, actual usable capacity is approximately 60-70% of rated capacity (about 18000-21000mAh at 5V). This is normal for all power banks.
